AB  - Avena sp. je prisutna u poljima žitarica. Dve najčešće prisutne vrste su A. fatua and A.
sterilis. Veoma su slične i praktično ih je teško razlikovati. Korišćenjem metode “Model
veštačkih neuronskih mreža” (MVNM) se mogu izdvojiti uzorci i na pouzdan način razdvojiti
navedene vrste. Razdvajanje je obavljeno na osnovu osobina semena Avena sp. prikupljenih sa
122 lokaliteta širom Balkana i severoistočne, zapadne i centralne Evrope (oko 22000
semena). Analizirane osobine semena: masa, veličina, boja, dlakavost i pozicija osja su
stavljene u odnos sa geografskom lokacijom uzorkovanja. Nakon analize dobijena je
pouzdanost razdvajanja Avena sterilis vs Avena fatua R2>0.99 i RASE<0.000001 (uz nivo
greške 0). Prednost ovog modela je što analizira relacije morfoloških osobina koje se ne mogu
lako definisati standardnim statističkim metodama. Kao primer se može navesti boja semena
koja se može upoređivati vezano za geografski lokalitet i druge osobine semena.
Poređenjem navedenih vrsta, preko posmatranih parametara, je konstatovano: 1)
pozicija osja kod A. fatua pretežno se nalazi na gornjoj polovini leme a kod A. sterilis na donjoj
polovini; 2) A. sterilis ima nešto duže seme i dlačice; 3) masa i dlakavost semena su slični kod
obe vrste i 4) semena A.fatua su uglavnom braon, svetlo braon i crne boje a kod A. sterilis crne,
braon i žučkaste.
Analiza je pokazala da razdvajanje A. fatua vs A. sterillis na osnovu pojedinačnih
osobina, a zbog prisustva zajedničkih osobina i stepena variranja, predstavlja veliki izazov.
Zbog toga ovaj pristup (MVNM) predstavlja potencijal za proučavanje morfoloških,
ekoloških i fizioloških osobina blisko srodnih vrsta.

AB  - The aim of our study was to evaluate the use of Raman spectroscopy for pre-diagnostic estimation of weed response to bleaching herbicides. Model plants were Chenopodium album and Abutilon theophrasti treated with mesotrione (120 g a.i. ha−1). Raman single-point measurements were taken 1, 2, 3, and 7 days after herbicide application from different points on the leaves. Principal component analysis (PCA) was carried out on data normalized by the highest intensity band at 1522 cm−1 and using spectral region from 950 to 1650 cm−1 comprising mainly contributions of carotenoids. The carotenoids by intensive band at ∼1522 cm−1 and bands with lower intensity at ∼1155 and 1007 cm−1 in treated plants were confirmed. According to PC1 (the first principal component) and PC2 (the second principal component), the highest intensity bands responsible for treatment differentiation in C. album could be assigned to chlorophyll, lignin, and carotenes. According to PC1 in A. theophrasti leaves the treatment differences could be observed 7 days after mesotrione treatment and PC2 gave a clear separation between all control and treated leaf samples. Raman spectroscopy may be a good complement to invasive analytical methods, in assessing the plant abiotic stress induced by bleaching herbicides.

AB  - Given the importance of different weed management systems (MS) for weed communities and soil seed bank, our aim was to study the impacts of organic (Org) and conventional (Conv) MS in tomato and sugar beet on the abundance of weeds and weed seed bank. The results have shown that in both crops the aboveground weed flora is dominated by 2–3 species in the Conv MS, while it is more diverse in the Org MS. In both crops the soil seed bank is less diverse when compared with the aboveground weed flora. Furthermore, a comparative analysis of the weed flora and soil seed bank has shown a high number of different weed seeds in the soil for tomato, unlike sugar beet, where a higher number of weeds was determined in the aboveground weed flora. In tomato, the soil seed bank is more diverse in Org MS (4.1 ± 1.5) than in Conv MS (3.8 ± 1.3), which was also true for the aboveground plant biodiversity (4.6 ± 1.1 vs. 3.6 ± 1.5 species, respectively). Also, although the differences in aboveground weed density and abundance in tomato were not statistically significant, seed bank reserves in the Org MS were significantly more abundant (40.4 ± 16.7 weed seeds vs. 4.5 ± 3.6 in Conv MS). This study has also shown that in sugar beet there were practically no differences between Org and Conv MS, even though the abundance of its aboveground weed flora was higher in Org MS (70.2 ± 29.4 vs. 38.1 ± 21.2 plants/m2 in Conv MS). In conclusion, it can be said that although both MS had similar effects on weed management in tomato, for sugar beet Org MS has proven to be less effective in weed control.

Takođe, fl oristički sastav zajednice zavisi i od starosti zasada. U mlađim zasadima dominiraju korovi okopavina, a sa starenjem zasada zajednica dobija korovsko-ruderalno-livadski karakter. Najčešće korovske vrste zasada jabuka u Srbiji su: Amaranthus retrofl exus, Ambrosia artemisiifolia, Carduus acanthoides, Chenopodium album, Convolvulus arvensis, Cynodon dactylon, Erigeron canadensis, Hordeum murinum, Lamium amplexicaule, L. purpureum, Medicago lupulina, Setaria spp., Sonchus arvensis, Stellaria media, Stenactis annua, Taraxacum offi cinale, Veronica spp., Vicia spp. itd. Za suzbijanje korova u zasadu jabuke preporučuju se agrotehničke (obrada zemljišta), fi zičke (košenje, malč prostirke), termičke, hemijske i biološke mere, kao i gajenje pokrovnih useva. U praksi za suzbijanje korova u zasadu jabuka se dominantno koriste herbicidi i to na bazi sledećih aktivnih supstanci: napropamid, glifosat, 2,4-D, fl azasulfuron, fl urohloridon, cikloksidim, fl uazifop-p-butil, kletodim, dikvat, fl uroksipir-meptil, pirafl ufen-etil i dr. S obzirom na dolazeće trendove sa imperativom proizvodnje zdravstveno bezbedne hrane i zahteva međunarodnog tržišta za očekivanje je da će biopreparati dobiti prednost u suzbijanju korova u zasadu jabuka u odnosu na klasične sintetičke herbicide. Osim toga, nehemijske mere takođe dobijaju sve više na značaju u sklopu integralnih mera zaštite zasada jabuka od korova.

AB  - Crop rotation is known as an eco-friendlier approach, as provides diversification in crop management systems, modifies intensive pressure on the agricultural ecosystem, utilizes various soil horizons, and prevents the establishment of specific pests and weeds. We set out here a study on the farms that have been managed over 50 years of specific continuous crop management programs. The experimental treatments were in a different management system: monoculture of maize, winter wheat, and soybean, 2-year crop rotation (winter wheat–maize) with and without chemical fertilizer, and 3-year crop rotation (winter wheat–soybean–maize) with and without chemical fertilizer and manure. We took soil samples six times from 2014 to 2017 prior to sowing and after harvesting each year. Weed seeds were extracted from soils and identified and counted by species. We, upon the data of a long term experiment of crop rotation, could conclude that crop rotations with more crops in the sequence are significantly effective in maintaining weed populations, a low-input crop production could reach a constant low population below an important damaging density, and therefore will be a more sustainable crop production while chemical fertilizers would change the soil’s chemical and structure and imbalance the plant population diversity and manures with high weed seed infestations have the potential to totally eradicate crop rotation effects, Therefore, clean manures or compost are highly recommended.

AB  - Herbicide application has long been considered the most efficient weed control method
in agricultural production worldwide. However, long-term use of agrochemicals has numerous
negative effects on crops and the environment. Bearing in mind these negative impacts, the EU
strategy for withdrawing many herbicides from use, and modern market demands for the production
of healthy and safe food, there is a need for developing new effective, sustainable, and ecological
weed control measures. To bring a fresh perspective on this topic, this paper aims to describe the most
important non-chemical weed control strategies, including ecological integrated weed management
(EIWM), limiting weed seed bank, site-specific weed management, mechanical weeding, mulching,
crop competitiveness, intercropping, subsidiary crops, green manure, and bioherbicides.

AB  - Evolucija rezistentnosti korova na herbicide možda je najjača pokretačka snaga u
traganju za herbicidima novih mehanizama delovanja, novih tehnologija u suzbijanju
korova i promovisanje najbolje prakse za održivu proizvodnju useva. Ovaj fenomen je
odličan primer brzog prilagođavanja biljaka ljudskoj aktivnosti, jer je odavno
potvrđeno da rezistentnost nije problem herbicida već ponašanja njihovih korisnika.
Ubediti poljoprivredne proizvođače da što ranije uvedu promene u upravljanje
rezistentnošću korova, predstavlja veliki izazov i dugoročni zadatak za sve
savetodavce i druge relevantne činioce u poljoprivredi. Najvažniji istraživački napori u
ovoj oblasti treba da budu usmereni ka razvoju ekonomski održivih strategija za
odlaganje pojave i upravljanje rezistentnošću. U Republici Srbiji do sada su potvrđeni
slučajevi rezistentnosti Amaranthus retroflexus L., Ambrosia artemisiifolia L.,
Helianthus annuus L. i Sorghum halepense (L.) Pers. na ALS inhibitore, kao i S.
halepense na pojedine inhibitore acetil koenzim A karboksilaze (ACC-aze) uključujući
i višestruku rezistentnost ove vrste na inhibitore oba prethodno pomenuta mehanizma
delovanja. Ekonomski najznačajnije korovske vrste u Srbiji su A. artemisiifolia, A.
retroflexus i S. halepense rezistentni na ALS inhibitore. Procenjuje se da su ove tri
korovske vrste sa svojstvom rezistentnosti na pomenute dominantne herbicide
rasprostranjene na stotinama hiljada hektara, pri čemu pričinjavaju najveće štete u
severnom delu Srbije. Značajne ekonomske štete prouzrokuju biotipovi S. halepense
rezistentni na pojedine herbicide inhbitore ACC-aze, odnosno na podrgrupu
ariloksifenoksi poropionata (FOP). Potvrđeni slučajevi rezistentnosti S. halepense na
pojedine inhibitore ACC-aze, zajedno sa slučajevima višestruke rezistentnosti na
inhibitore ACC-aze i ALS inhibitore, rasprostranjeni su za sada samo u jugozapadnoj
Bačkoj (opštini Bač). Ovi nalazi su opomena da je potrebno više nego ikad dosledno
sprovođenje antirezistentne strategije na celoj teritoriji Srbije. To podrazumeva edukaciju, praćenje rezistentnosti korova prema dominantnim herbicidima i
sprovođenje proaktivnog i aktivnog upravljanja rezistentnošću korova na herbicide.
Stanje mera antirezistentne strategije procenjeno je u 2019. godini anketiranjem 914
poljoprivrednika i agronoma od kojih 96,8% donose odluke u izboru i primeni
herbicida. Prema ovoj anketi, kod većine useva dominantni herbicidi su ALS inhibitori,
a u plodoredu su uglavnom zastupljene smene dva ili u manjem procentu tri useva.
Smeše herbicida različitih mehanizama delovanja uvek koristi 24,6% anketiranih,
42,2% često, 21,8% povremeno, 8,4% retko i 2,8% nikad. Smenjivanje herbicida
različitih mehanizama delovanja u vremenu i prostoru uvek koristi 20,2% anketiranih,
često 37,9%, povremeno 26%, retko 12,3% i nikad 3,5%. Obradu zemljišta, kao
dodatak hemijskom suzbijanju korova, uvek koristi 42,2% anketiranih, 33,1% često i
15% povremeno. Od ukupnog broja anketiranih koji su odgovorili na pitanje, uputstvo
za primenu pri izboru količina i vremena primene herbicida uvek se poštuje kod
78,9%, često kod 17,6%, povremeno 2,4%, retko 0,6% i nikad kod 0,5%. Od
najvažnijih vrsta korova koje se otežano suzbijaju herbicidima najčešće su navedeni:
S. halepense (82,7%), Cirsium arvense (L.) Scop. (47,8%), Xanthium strumarium L.
(43,8%), A. artemisiifolia (43,5%), Amaranthus spp. (31,1%) itd. Sa prisustvom
korova rezistentnih na herbicide u Srbiji upoznato je 67,3% od ukupno 856
anketiranih, a u svojoj opštini 69,5% od ukupno 629 anketiranih. Iskustva sa korovima
rezistentnim na herbicide na svom gazdinstvu imalo je 57,5% od ukupno 515
odgovora. Od najvažnijih vrsta korova kod kojih je potvrdjena rezistentnost na
herbicide u opštini, najčešće su navedeni: S. halepense (77,2%), A. retroflexus
(20,2%) i A. artemisiifolia (19,4%). Slične vrednosti su i za pretpostavku koje vrste su
rezistentne na njihovom gazdinstvu (S. halepenese 71,6%, Amaranthus spp. 19,1% i
A. artemisiifolia 15,5%). Poljoprivrednici su do informacija o rezistentnosti najčešće
dolazili na savetovanjima (62,5%). Mehanizme delovanja herbicida razume 72% od
812 anketiranih i oni su ujedno upoznati da se oznake mehanizama delovanja
herbicida nalaze na etiketi herbicidnih preparata. Međutim, značenje ovih oznaka
razumelo je 62,6% od ukupno 808 odgovora. Od specifičnih mera antirezistentne
strategije od 563 dobijenih odgovora, najčešće se koriste: smena herbicida različitih
mehanizama delovanja u plodoredu (50,8%), smena herbicida različitih mehanizama
delovanja u usevu (29%), korišćenje maksimalne preporučene količine herbicida
(32%), upotreba rezidualnih (zemljišnih) herbicida posle setve a pre nicanja (25,8%),
primena glifosata pre setve ili posle setve a pre nicanja useva (33,2%), osnovna
obrada zemljišta oranjem (36,6%), smena žitarica i širokolisnih useva (31,4%), smena
ozimih i prolećnih useva (33,2%) i dopunska obrada zemljišta kao dodatak
herbicidima (36,1%). Na pitanje da li se čiste poljoprivredne mašine (kombajne) pre
prelaska sa jednog polja na drugo da bi se smanjilo širenje semena korova, od
ukupno 799 odgovora, 20,3% uvek to radi, 14,1% često, 22,8% povremeno, 21,9%
retko i 20,9% nikad. Na pitanje da li se vodi evidencija (knjiga polja) o primeni
herbicida i drugih agrotehničkih mera, pozitivan odgovor je dalo 69,2%. Na osnovu
analize prethodnog stanja, postaje više nego ikad značajnije da poljoprivrednici počnu
da razmišljaju izvan okvira starog modela suzbijanja korova ukoliko žele da sačuvaju
upotrebljivost postojećih herbicida koje već imaju i obezbede da herbicid sa novim
mehanizmom delovanja, koji će se pojaviti, dostigne svoj pun potencijal. Za razliku od
drugih država, koje su odavno prepoznale značaj ovog problema, u Srbiji ne postoji
organizovano praćenje rasprostranjenosti populacija rezistentnih korova prema
pojedinim herbicidima. Upravljanje rezistentnošću korova na herbicide održivo je
jedino zajedničkim naporom svih relevantnih aktera: poljoprivrednika i njihovih
udruženja, proizvođača i prometnika herbicida, univerziteta, instituta, nadležnih ministarstava i sekretarijata, savetodavaca, vlasnika zemljišta, profesionalnih
udruženja, medija, nevladinih organizacija i dr. Veoma važno je podsticanje
zajedničkih aktivnosti pomenutih relevantnih subjekata, jer svako dalje ignorisanje i
odlaganje mera za upravljanje rezistentnošću korova na herbicide može
prouzrokovati nesagledive posledice po poljoprivredu Srbije.

AB  - Recent reports of the presence of Ambrosia trifida (AT) in areas infested by A. artemisiifolia (AA) in Serbia warn of the impending establishment of a more damaging crop weed. Here, we test the potential competitive effects of these two weed species. We conducted a field competition study in 2016 and 2017 as a replacement series experiment arranged in a split plot, with main plots (20.5 m × 2 m) at total plant densities of 10 and 100 plants/m2, and sub-plots (3 m × 2 m) at the proportion of AT to AA of 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100. Individual plant biomass (IPB) for AT was lowest when grown in monoculture, while AA reached its highest IPB in its monoculture. With AT < 40%, the AT IPB was larger than (2017) or the same as AA (2016). With AT > 40%, its IPB decreased due to increased intraspecific competition. We obtained the lowest sub-plot biomass (SPB) of AT + AA in mixtures with 40:60 and 60:40 ratios, and also the highest SPB of other weed species. We show that despite a larger leaf area, AT may not fully replace AA and thus not become a new threat to crops, as it not only suffers from intraspecific competition at high densities, but also from interspecific competition with AA. Therefore, crops may benefit from a stable coexistence of both species as compared to highly dominant AT or AA. Further studies in the presence of crops are needed to confirm this hypothesis.

AB  - Ambrosia artemisiifolia (common ragweed) and A. trifida (giant ragweed) are very important weed species that are invasive in Serbia and are often found in agricultural regions. When these weeds are present at high densities, crop yields can be significantly reduced or even completely destroyed. Unlike A. artemisiifolia, A. trifida is locally present in the Central Bačka region (Vojvodina province), and it is expected that its area of distribution will expand in the future. Starting from the assumption that future distribution of A. trifida could take on larger proportions than now, the aim of this study was focused on examining the interaction between these two species. Experiments were conducted using the replacement design model, in which Ambrosia trifida/Ambrosia artemisiifolia per m2, were planted as density ratios of 10/0; 8/2; 4/6; 6/4; 2/8, and 0/10, in a completely randomized block system with four replications. The vegetative parameters (height and dry mass) of A. artemisiifolia were measured in July, August and September over a period of two years (2016 and 2017), and the results were statistically analysed in the Statistical Package for the Social Sciences (SPSS 23). In July 2016, the average height of A. artemisiifolia was in the range between 35.00 and 50.40 cm, in August it was from 68.00 to 95.50 cm, and between 83.75 and 99.80 cm in September. In the following season (2017), the corresponding values ranged from 56.19 to 78.50 (July), 98.38 to 125.50 cm (August) and 111.19 to 148.50 (September). An increase in the number of A. artemisiifolia plants and decrease in A. trifida counts per m2 caused an increase in the dry mass of A. artemisiifolia per plant. The dry mass of A. artemisiifolia ranged from 4.22 to 6.11 g/plant (July), 8.96 to 10.27 g/plant (August) and 7.04 to 19.53 g/plant (September). In the following season, these values ranged from 9.62 to 14.60 g/plant, 14.37 to 28.90 g/plant, and 23.43 to 40.47 g/plant in July, August and September, respectively. Minimum values of vegetative parameters were recorded in the treatment with 2 plants, and maximum in the treatment with 10 A. artemisiifolia plants/m2. This means that interspecific competition is more pronounced in this ragweed species than intraspecific competition.

AB  - Intraspecific variation in spikelet and seed morphology was assessed for eleven populations of common wild oat (Avena fatua L.). Spikelet lengths varied between 1.13 and 1.81 cm, with highly significant differences being recorded between most analyzed populations. Lemma color varied between ocher, light-brown, brown and black, with the majority of analyzed populations (63.64 %) having predominately (≥50%) brown lemma color. Percent of lemma hairiness was also assessed and yielded some highly significant differences between the populations. Length of the awn varied between 2.34 and 4.74 cm, with differences in mean values of awn length per population being statistically significant between several analyzed populations. The angle between the awn and the dorsal surface of lemma was also studied and varied between 85.76° and 140.71°. Analysis of grain length has shown highly significant differences only between the populations from Bačevci (BIH02) and Aleksandrovac (BIH03), when compared with other nine analyzed wild oat populations, while contrary to this, grain mass was shown to be a highly significant factor when comparing wild oat populations. Consequently, it can be theorized that the wide range of variation documented for certain seed morphology traits results from a high local differentiation potential of wild oat populations.

AB  - Pored Ambrosia artemisiifolia L. koja je raširena na većem delu teritorije Srbije, Ambrosia trifida L. je za sada lokalno prisutna. Uzimajući u obzir njen vegetativni i generativni potencijal može se očekivati njeno dalje širenje i samim tim veće štete u poljoprivredi. Cilj ovih istraživanja bio je da se odredi koliki je uticaj A. artemisiifolia na vegetativni prinos A. trifida u uslovima njihove koegzistencije. Eksperiment je postavljen po modelu zamenjujućih serija ("Replacement Design") gde je praćena intra i interspecijska kompeticija. Ogled je postavljen u šest tretmana (potpuno slučajan blok sistem u četiri ponavljanja) sa različitim proporcijama biljaka m-2 A. artemisiifolia/A. trifida (%): 100:0, 80:20, 40:60, 60:40, 20:80 i 0:100 u dve serije: mala (ukupno 10 biljaka m-2) i velika gustina (ukupno 100 biljaka m-2). Tokom sezone u tri ocene merena je suva biomasa biljaka A. trífida i A. artemisiifolia pri čemu će ovde rezultati biti prikazani samo za A. trifida. Za ispitivanje analiziranih parametara korišćena je trofaktorska analiza varijanse (ANOVA) a podaci su obrađeni u statističkom paketu SPSS. Kod tretmana sa niskom brojnošću biljaka, prosečne vrednosti suve mase A. trifida kretale su se u rasponu od 5,36-8,99 g biljka-1 (jul), zatim od 7,4-13,01 g biljka-1 (avgust) i od 9,08-16,13 g biljka-1 (septembar) dok su se u tretmanu visoke brojnosti vrednosti kretale u rasponu od 6,35-8,38 g biljka-1 (jul), 8,66-11,71 g biljka-1 (avgust) i 9,53-13,54 g biljka-1. Dobijeni rezultati pokazuju da je kod A. trifida izražena interspecijska kompeticija (pri manjoj brojnosti populacije), dok sa povećanjem broja jedinki po jedinici površine više dolazi do izražaja intraspecijska kompeticija.

AB  - The application of minimal doses of herbicides is very popular due to concerns about the negative impacts of herbicides on the environment and public health. Studies were conducted to estimate the possibility of using quick and non- destructive methods to investigate Chenopodium album L. and Abutilon theophrasti Medik. response to mesotrione. The studies were conducted in a controlled environment to determine the response of C. album and A. theophrasti to mesotrione using dose–response curves created based on plant dry weight, chlorophyll fluorescence parameters and chlorophyll content. The obtained effective dose values showed that the studied weeds were susceptible to reduced doses of mesotrione. ED95 values estimated for both species for dry weight and chlorophyll fluorescence parameters were lower than the recommended dose rate (120 g a.i. ha−1), with less than 85 g a.i. ha−1 needed to achieve a reduction of 95%, compared with untreated plants, while ED95 value (A. theophrasti: 182 g a.i. ha−1 and C. album: 180 g a.i. ha−1) for chlorophyll content for both species was above the recommended dose rates. Consequently, dry weight and the chlorophyll fluorescence parameters are suitable for estimating the plant response to mesotrione, while chlorophyll content is not.

AB  - Gene flow is a main concern associated with the use of herbicide resistant sunflower crops because it could transfer herbicide resistance traits to weedy sunflower. In order to estimate potential gene flow from imazamox and tribenuron-methyl resistant sunflower hybrids to weedy sunflower, field experiments and DNA analysis were conducted. The progeny of weedy sunflower which grown near imazamox (WS1) and tribenuron-methyl (WS2) resistant hybrid in previous experiments were used. In the field experiment, recommended rates of imazamox and tribenuron-methyl were applied to WS1 and WS2, respectively, and plants surviving were recorded. Herbicides effect on fresh weight of survived plants were also determined. The presence of mutations responsible for sunflower resistance to herbicides (imazamox and tribenuron-methyl) checked based on DNA analysis of selected survived plants. Percentage of survived plants in field experiment was recorded at maturity and depend on weedy sunflower accession (WS1 or WS2) and distance of their mother plants from resistant sunflower hybrid in previous experiment and was higher for WS2 (50.25%) than for WS1 (24.50%). As DNA analysis were not confirmed the presence of the point mutations responsible for sunflower resistance to imazamox and tribenuron-methyl.

AB  - Ambrosia artemisiifolia is considered a serious and problematic weed in crops and other crops, but also on non-agricultural land in Serbia. Due to the early rapid growth in spring and the large vegetative and generative production, as well as the seeds that maintain germination in the soil for many years (up to 40 years) it is very difficult to control the spread. Also, its related species Ambrosia trifida, currently only locally present in the territory of Serbia, is in the focus of interest of many researchers dealing with invasive biology. It does great damage to crops, reducing yield and product quality. Also, both weed species have a negative impact on human and animal health with their allergens, so it is necessary to continuously monitor and implement adequate suppression measures, as well as to continuously promote the topic and inform the public about problems and damages that they cause.

AB  - Development of herbicide-resistant (HR) crops is way to overcome problems in weed control due to weed resistance to herbicides and absence of new herbicides with a new mode of action for their control. Three types of HR crops were developed: nontransgenic, transgenic, and multiple HR crops. Cultivation of HR crops is associated not only with many benefits (simplification of weed control, more effective and efficient weed control, higher yields, etc.) but also with various risks (development of HR weeds, development of HR volunteer crops, gene flow from HR crops to susceptible relatives, etc.). The greatest risk is gene flow from HR crops to related weed species, wild relatives or conventional crops of the same species. Unwanted gene flow could be prevented or reduced using different barriers such as isolation in space or time, protective vegetation barriers, male sterility, etc. Sunflower hybrids resistant to herbicides (imidazolinones and sulfonilureas) was developed by conventional breeding methods, and their introduction in Serbian fields has enabled a more efficient control of harmful weed species, but the presence of huge populations of weedy sunflower is the main concern associated with their cultivation, because numerous studies have confirmed gene flow from sunflower to its relatives.

AB  - Unfortunately, herbicide resistance developed shortly after the introduction of the herbicides 2,4‐D in 1957. According the herbicide resistance mechanisms, all processes can be grouped as follows: target‐site resistance, non‐target‐site resistance, cross‐resistance and multiple‐resistance. Target‐site resistance is generally due to a single or several mutations in the gene encoding the herbicide‐target enzyme, which, in turn, decreases the affinity for herbicide binding to that enzyme. Non‐target‐site resistance is caused by mechanisms that reduce the amount of herbicidal active compound before it can attack the plant through the reduced absorption or altered translocation, increased herbicide sequestration or enhanced herbicide metabolism. Cross‐resistance means that a single‐resistance mechanism causes resistance to several herbicides with some mode of action. Multiple‐resistance is a situation where two or more resistance mechanisms are present within the same plant, often due to sequential selection by herbicides with different modes of action. Currently, herbicide resistance has been reported in 478 weed biotypes (252 weed species) in 67 countries. Many of those biotypes are resistant to acetolactate synthase (ALS) inhibitors, PS II inhibitors, ACC‐ase inhibitors and EPSPS inhibitors. Strategy for herbicide‐resistance weed management must involve all the available preventive, cultural, mechanical and chemical measures for effective, safe and cost‐effective weed control.

AB  - Velvetleaf (Abutilon theophrasti Medik.) is an invasive alien species in many countries and one of the major weeds in summer row crops worldwide. Weed-management techniques that reduce weed production need to be investigated to provide new approaches. The first step in this process is the determination of weed productivity in different competitive conditions. Field experiments were conducted in 2006 and 2008 in an experimental field in Padinska Skela to quantify growth and seed production of velvetleaf in maize, as well as in a velvetleaf monoculture. A density of velvetleaf ranging from 1 to 8 plants m-1 was artificially created. In a mixture with maize, velvetleaf was sown in crop rows. The growth of velvetleaf was estimated based on plant height, fresh aboveground biomass and leaf area index (LAI). Velvetleaf fecundity was determined as seed mass plant(-1) and seed mass m(-2). Differences between years in plant production were very prominent. In general, velvetleaf productivity in maize depended on its density. Intraspecific competition had a major influence on growth and seed production when velvetleaf density was from 4 to 8 plants m(-1) in maize rows. This information indicates that environmental conditions and weed density can promote/reduce inter-and intraspecific competition and help in the construction of population dynamics models to predict population density, seed bank and competitiveness of weeds and reduce inputs for weed management.

AB  - As the plant matures numerous changes at the morphological, physiological and anatomical level occur, leading to changes in the susceptibility to herbicides. Anatomical characteristics of apical fully developed leaves of Chenopodium album were studied in this paper. From plants at 2, 4, 6, 8 and 10 leaves stage, fully developed leaves were sampled and used to make permanent slides for light microscopy. The following parameters were measured on permanent microscope slide samples: thickness of the leaf, epidermal adaxial and abaxial, thickness of the mesophyll, palisade and spongy tissue. The obtained results have shown that maturing of the C. album plants can affect the anatomical structure of its fully developed leaves. Hence, it has been confirmed that the tissue thickness in leaves collected from plants in younger stages of development is significantly different from the tissue thickness of corresponding leaves collected from older plants.

AB  - Weedy sunflower has become a problem worldwide, giving significant yield losses in sunflower and soybean fields even at low densities, decreasing their oil quality and allowing gene flow among crops and weeds. Its evolution differs among countries due to availability of wild forms. The problem is not only weedeness but also herbicide resistance in the Republic of Serbia. Three weedy sunflower populations from Serbia were studied: RWS1 and RWS2, which were presumably ALS herbicide resistant and SWS which is susceptible. Plant height, fresh weight, leaf area, relative chlorophyll content, fecundity and percentage of germination, length and weight of seedlings with and without nicosulfuron application were recorded. The most frequently RWS1 and RWS2 populations were of better ecological fitness than the SWS population under the conditions with and without nicosulfuron application. The number of seed produced was higher in RWS1 without herbicide application and RWS2 with nicosulfuron application. It was concluded that the differences in the level of herbicide-resistance could result in different fitness level of weedy sunflower populations which could promote the invasiveness of these populations in landscape.

AB  - Weedy sunflower Helianthus annuus L. (WS) can become troublesome for cultivated sunflower given their genetic similarity which allows gene flow from weed-to-crop and from crop-to-weed. Also, it causes yield losses in different spring-sown crops. Despite this, there is still no data about its response to herbicides. Field experiments were conducted to quantify the effects of nicosulfuron on WS populations. Plants of three populations (R1-WS and R2-WS = presumably resistant and S-WS = susceptible) were treated with 40 g nicosulfuron ha-1 at the 2–4 true-leaf growth stage. Vegetative parameters (plant height, fresh weight, leaf area) and relative chlorophyll content (RCC) were measured 30 days after herbicide application. Generative parameters (number of heads plant-1, head diameter, number of seeds plant-1) were measured at maturity. After harvesting, seed germination of collected seeds was studied in Petri dishes at 25°C. Nicosulfuron was found to have a significant effect on vegetative and generative production of WS plants. The effect on RCC and postharvest seed germination was not so prominent. All this effects depended on the population, which is probably a result of different history of herbicide application and possible development of resistance in the populations R1-WS and R2-WS.

AB  - This work present two basic biological processes of seed dormancy and germination. Seed dormancy can be characterized as a basic for survival maintenance and expansion in agroecosystem, while, germination is the initial stage of plant development. Based on the research results of a large number of researchers, the work especially shows the behavior of weed seeds in the influence of the most important enviromental factors (water, temperature, light, soil), as well as the laws that govern these processes. Knowing reserves of weed seeds in the soil and their biological and ecological characteristics it is possible to predict when and how many seeds will germinate under certain climatic and soil conditions. A model for the evaluation of the appearance of weed plants and their effective in suppression of a given crop can be made, as well as an assessment on the potential invasiveness of cerain weed species.

AB  - The response of two populations (CC1, 43.59 degrees N & 20.40 degrees E; CC2, 44.46 degrees N & 20.17 degrees E) of common cocklebur (Xanthium strumarium L.) to nicosulfuron was investigated both in field experiments and in the laboratory. Population CC1 had no history of treatment with any herbicide, while population CC2 was treated with ALS inhibitor herbicides for six consecutive years. In the field, plants were treated post-emergence with nicosulfuron (0, 10, 20, 40, 60 and 80 g ai ha(-1)) at four true leaves. Visual injury estimation and vegetative parameters (plant height, fresh weight, leaf area) were recorded about month after herbicide application. The acetolactate synthase (ALS) enzyme activity in response to herbicide concentrations of 0, 0.01, 0.1, 1, 10, 100 mu M was determined in vitro. GR(50) values for vegetative parameters and 150 values for ALS activity were slightly greater for the CC2 than for the CC1 population, but the results confirmed that neither population was susceptible to nicosulfuron. Namely, based on results for fresh weight, the population CC1 was about 3.9 and 2.6-fold more susceptible CO nicosulfuron than population CC2 in two consecutive years, but differences were not so prominent for other parameters (plant height, leaf area and ALS activity), ranging from 1.18 to 1.8-fold. The differences between population CC1 and CC2 could be attributed to inter-population variability in susceptibility CO nicosulfuron or could be the consequence of repeated application of ALS herbicides to the CC2 population during the six previous years. Future investigations are necessary in order to clarify this dilemma.
