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  - 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  - 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  - 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  - 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.

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  - Crop rotation, soil cultivation and weed control measures are in direct correlation with the content of the weed seed bank in the soil. Knowing the weed seed bank and the dynamics of the weed emergence is the basis for planning and implementing the measures for effective weed control. The research was carried out on the plots of the long-term stationary experiment 'Plodoredi' of the Institute of Field and Vegetable Crops in Novi Sad. During August of 2014, following the soybean harvest, the soil from the plots under different cultivation systems was sampled: soybean monoculture and 3-field (soybean, wheat, corn). Two methodological procedures were used to evaluate the reserve of seeds in the plough layer and the under plough soil layer. The physical extraction of seeds has determined the total content of weed species in the seed bank, while seed germinarion was used to determine which of the observed species are capable of germinating in the following period. The method of physical extraction has determined that the highest number of seeds was present in the soil samples from the soybean monoculture, in the depth layer of 15-30 cm. The under plough soil layer was characterized by a lower number of seeds, in both variants. In the study of germination, which was conducted under controlled conditions 18 months after the sampling, the best seed germination was recorded for the seeds of Ambrosia artemisiifolia L., Chenopodium hybridum L. and Chenopodium album L.

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  - 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.

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.",

AB  - Weedy forms of cultivated sunflower (Helianthus annuus) are invasive species widely distributed in several regions of the world and are commonly controlled by applying acetohydroxyacid synthase (AHAS)-inhibiting herbicides, such as imidazolinones (IMIs) or sulfonylurea (SUs). The widespread adoption of herbicide-resistant crops has exposed the weedy population to the high risk of crop-to-weedy gene flow. The aim of this study was to check and quantify the gene flow from IMI- and SU-resistant sunflower hybrids to weedy sunflower populations. Field experiments were conducted in 2008 at two sites in Serbia to evaluate the relationship of distance between the crop and the weedy sunflower and its impact on the percentage of gene flow. The weedy sunflower progenies were evaluated through herbicide resistance and SSR marker study. Hybridization with IMI-resistant hybrids was not confirmed. Conversly, SU-resistance trials and SSR marker studies partially confirmed the transfer of resistance within the weedy population.

Three treatments (T1- storage at room temperature; T2 - exposure to 4°C for 30 days; T3 - scarification by concentrated sulphuric acid) differing in manipulation with seeds before germination were tested at different temperatures (5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C). Germinated seeds were counted daily for ten days and the length of seedlings was measured on the last day. The results showed that differences in germination of C. campestris seeds were very prominent between temperatures, as well as between treatments T1, T2 and T3. Seeds failed to germinate at 5°C and 45°C in all treatments (T1, T2, T3). Germination ranged from 6.25 at 10°C to 96.88%, the highest percentage, achieved at 30°C.
AB  - Izučavanje bioloških karakteristika semena i uslova u kojima klijaju ima veliki značaj za planiranje i realizaciju racionalnih mera za kontrolu korova. Cilj ovog istraživanja je bio da se ispita efekat različitih temperatura na klijanje semena C. campestris. U ogled su bila uključena tri tretmana (T1 - semena čuvana u laboratorijskim uslovima na temperaturi 22- 25°C, T2 - semena koja su prethodno 30 dana izlagana niskoj temperaturi (4°C), T3 - semena koja su skarifikovana koncentrovanom sumpornom kiselinom), pri čemu su svi tretmani ispitivani na sledećim temperaturama: 5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C. Svakodnevno, u periodu od deset dana, rađeno je prebrojavanje proklijalih semena, a poslednjeg dana su izmerene i dužine klijanaca. Dobijeni rezultati ukazuju da postoje značajne razlike u klijanju semena u odnosu na ispitivane temperature i tretmane. Semena nisu klijala na temperaturama od 5°C i 45°C ni u jednom od rađenih tretmana. Procenat klijanja se kretao od 6,25% do 96,88%, pri čemu je najveći procenat u sva tri tretmana zabeležen na temperaturi od 30°C.

AB  - Field experiments were conducted in 2008 and 2009 at the Experimental Field Institute Padinska Skela PKB Agroekonomik, near Belgrade, to quantify effects of nicosulfuron on plant traits (vegetative production and fecundity) of Xanthium strumarium. Plants of X. strumarium were grown in monoculture on plots of 5 x 4.2 m. Inter-row spacing was 24 cm and the distance between the rows was 70 cm. Plants were treated with nicosulfuron when they developed two pairs of leaves. The applied rates of nicosulfuron were 20, 40 and 80 g a.i. ha(-1) and one control treatment (without herbicide application) was included. Vegetative parameters (height, fresh weight, leaf area and leaf area index (LAI)) were recorded just before herbicide application and four times after the herbicide treatment. Measurements were made at intervals of about two weeks. At maturity, fecundity of weeds (bur weight plant(-1) and bur number plant(-1)) was measured. In both years, the application of nicosulfuron caused less growth (height, fresh weight and LAI) of X. strumarium in comparison with the control. All rates of nicosulfuron reduced vegetative parameters, which decreased as rates of nicosulfuron increased. On the other hand, effects of nicosulfuron on bur production were not equivalent to its effects on vegetative parameters. Only the highest rate of nicosulfuron reduced bur production significantly.

AB  - Changes in leaf anatomy were examined in two S. African populations of Conyza canadensis of which one was presumed to be resistant (CCPR) and the other susceptible (CCS) to glyphosate. Glyphosate was applied to plants, which were grown from seed collected from these populations, at rates of 1, 2 and 4 kg a.e. ha(-1) of TOUCHDOWN [active substance: glyphosate trimesium salt, 500 g L-1] that are equivalent to 2, 4 and 8 L ha (-1) of the herbicide Touchdown. Leaf samples for the light microscope (LM) analysis were collected 3, 7 and 24 h after treatment (HAT). Changes in chlorophyll and shikimate content of leaf material were also examined. Changes in the palisade and pith tissue of leaves were not detected in the investigated populations at 3 and 7 HAT. However, at 24 HAT the different herbicide doses caused changes in leaf anatomy. These changes (injuries) were detected in the CCS at all tested doses, but in the CCPR population of C. canadensis the injuries were observed at only the two highest rates, 2 and 4 kg a.e. ha(-1). Chlorophyll and shikimate contents indicated significant differences between the treated and untreated plants of susceptible population only. Difference in glyphosate resistance between the CCS and CCPR populations was confirmed with an index of resistance of 1.58. This value of the index of resistance indicates that CCS population is 1.58 times more susceptible to glyphosate compared to CCPR population. (C) 2013 Friends Science Publishers

AB  - Weed control in rapsberry and blackberry plantings during the 2007 vegetation season was evaluated using three herbicides: Casoron G (a.i. dichlobenil 67.5 g/kg) with application rates of 60 and 80 kg/ha, foliar treatments of Galop (a.i. paraquat 200 g/L) at 4.0 L/ha and Bonaca EC (a/o/fluroxypyr-meptyl 360 g/L) at 0.8 and 1.0 L/ha. Bonaca (1 L/ha) showed the best efficacy against all broad leaf weed species and Casoron G (80 kg/ha) against all grass weed species. None of the combinations showed sufficient efficacy ( gt 95%) against Cynodon dactylon or Sorghum halepense.

AB  - A timely and proper weed control imposes the need to identify the floristic composition and biology of weed community in raspberry plantings. A survey was conducted in more than 40 raspberry plantings (southwest part of Serbia) and about 85 weed species (68 broadleaf and 17 grass species) were registered. At the study area, the predominant grass weed species according to abundance and cover values were: Panicum crus-galli L., Setaria glauca (L.) P. B., Setaria viridis (L.) P. B. and Digitaria sanguinalis Scop.; and broadleaf species: Amaranthus retroflexus L., Amaranthus hybridus L., Chenopodium polyspermum L., Erigeron canadensis L., Galinsoga parviflora Cav., Glechoma hederacea L., Polygonum lapathifolium L., Convolvulus arvensis L., Calystegia sepium R.

AB  - A better understanding of the seed ecology can be helpful for prediction of the potential of weed species to spread, for prediction of their invasiveness, and for development of more effective weed management strategies. In Serbia, in agricultural areas, edges of crop fields, as well as in uncultivated areas, more and more populations of common cocklebur (Xanthium strumarium L.) were detected. Seeds from two populations (P-1 and P-2) of this species were collected for testing temperature effects on germination. Germination tests were conducted in an incubator set to 10, 15, 20, 25, 30 and 35 degrees C, in the dark. The seeds were considered to be germinating at the moment of radicle emergence. The number of germinated seeds was recorded daily (germination rate) during 7 day period and germination rate (sum of germinations per day) was calculated. Final percentage of germination and seedlings length and weight were measured after 7 days of incubation. Seeds of the both common cocklebur populations did not germinate when incubated at 10 degrees C. The lowest germination occurred at 35 degrees C for population PI and at 15 degrees C for population P-2, while the maximum germination occurred at 25 degrees C for both populations. The highest length of seedlings were recorded at 25 degrees C and 30 degrees C for population P-1 and P-2, respectively, while the highest seedlings weight was at 35 degrees C for both populations. The lowest seedlings length, as well as weight, was measured at 15 degrees C for both populations.

AB  - Soil bacteria are able either to stimulate or inhibit seed germination. If seed germination is stimulated, the seedlings of weed species emerge more uniformly, so that they could be killed in the next step of weed control. This investigation focused on testing the germination of Ambrosia artemisiifolia L. on several media: Pseudomonas fluorescens (B1), Azotobacter chroococcum (B2), Bacillus licheniformis (B3), B. pumilus (B4), B. amyloliquefaciens (B5). In control, seeds germinated in water. Seed germination varied depending on bacterial media. Germination was inhibited by bacterial treatments B1 and B3, treatments B2 and B4 stimulated germination, while germination in treatment B5 was similar to control.
AB  - Zemljišne bakterije mogu imati stimulativno ili inhibitorno delovanje na klijanje semena mnogih biljaka. Ukoliko je klijanje semena stimulisano, ponici korova se javljaju znatno uniformnije, što pruža realnu mogućnost da se u nekoj od narednih operacija nege useva korovi eliminišu. U ovim istraživanjima ispitivan je uticaj nekoliko zemljišnih bakterija (Pseudomonas fluorescens (B1), Azotobacter chroococcum (B2), Bacillus licheniformis (B3), B. pumilus (B4), B. amyloliquefaciens (B5) na klijanje semena alohtone invazivne korovske vrste Ambrosia artemisiifolia L. U kontrolnu varijantu je dodata česmenska voda. Na osnovu dobijenih rezultata može se konstatovati da je klijanje semena A. artemisiifolia variralo u zavisnosti od toga na kojoj bakterijskoj podlozi je vršeno naklijavanje. Naime, utvrđen je manji procenat klijavosti semena na podlozi B1 i B3, odnosno veća klijavost je postignuta na podlogama B2 i B4 u odnosu na čistu vodu. Osim toga, klijanje semena A. artermisiifolia na podlozi B5 je bilo gotovo istovetno kao i u čistoj vodi (kontroli).

AB  - Weed resistance is more and more becoming a problem under intense agricultural conditions. Recognizing this problem has high practical importance not only for detection of resistant weeds but also for application of measures for prevention of development of resistance or control of already resistant weed populations. In this article we are explaining the meaning of resistance and development of resistant weeds. We are also giving historical and present information about herbicide weed resistance in our country and in the world. Additionally, we describe how to test presumably resistant weed populations and how to determine the level of resistance. We also give an overview of different factors which influence development of resistance and the possibility to predict development of weed resistance.
AB  - Rezistentnost korova na herbicide sve više postaje ozbiljan problem u uslovima intenzivne poljoprivredne proizvodnje. Poznavanje ove pojave ima veliki praktični značaj kako za detekciju rezistetnosti u polju, tako i za preduzimanje mera za sprečavanje pojave ili suzbijanje rezistentnih populacija ukoliko su se već razvile. U ovom radu je objašnjen pojam i razvoj rezistentnosti korova na herbicide. Takođe, dati su istorijat i stanje rezistentnosti korova na herbicide u Svetu i kod nas. Opisano je kako se testira osetljivost pretpostavljeno rezistentnih populacija na herbicide i kako se određuje nivo rezistentnosti. Osim toga, sagledan je uticaj različitih faktora na razvoj rezistentnosti, kao i mogućnosti prognoze nastanka ove pojave. Takođe, razmatrane su potencijalne strategije za izbegavanje ili bar odlaganje rezistentnosti, kao i mogućnosti suzbijanja rezistentnih populacija ukoliko su već nastale.

AB  - The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid 'Zoltan' (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activity was estimated in vivo 24 h after imazethapyr application. Tolerance level was determined based on the resistance ratio index (ED50 - herbicide dose causing 50% growth inhibition of T hybrid/ ED50 of S hybrid). Significant differences were noted between the hybrids in the in vivo ALS activity and vegetative parameters. Indexes of resistance ranged between 5 and 452 for vegetative parameters, whereas the index for ALS activity was 210. The data confirmed the high level of tolerance of the hybrid Rimi as compared with the hybrid Zoltan.
