Abstract
Biological control is an innovative, cost effective and eco-friendly approach for control of many plant diseases. Bacillus sp. and Trichoderma sp. were known for its mycoparasitic and antagonistic mechanism in the control of wide range of phytopathogenic diseases in many types of crops. This research is based on the antibacterial activities of some Bacillus spp. and Trichoderma harzianum in relation to the 10 selected phytopathogenic bacteria in vitro study. The results indicated that among 52 strains of Bacillus spp. presented against phytopathogenic bacteria, only 6 of them showed inhibition but only against Xanthomonas genera. Other Bacillus spp. strains weren't effective against tested phytopathogenic bacteria. Results of testing of T. harzianum efficacy against the growth of selected phytopathogenic bacteria showed that this fungi could be effective to strains from genera Pseudomonas and Xanthomonas but for other tested genera was ineffective. In further work, all of this trial ne...ed to be supported by evaluation of antimicrobial activity in vivo.

Biološka kontrola predstavlja inovativni, isplativ, ekološki pristup za suzbijanje mnogih biljnih bolesti. Vrste roda Bacillus i Trichoderma su poznati po svom mikoparazitskom i antagonističkom mehanizmu suzbijanja širokog spektra fitopatogenih prouzrokovača bolesti kod brojnih poljoprivrednih kultura. U ovom radu proučavano je baktericidno delovanje nekih vrsta roda Bacillus, kao i gljive Trichoderma harzianum na 10 odabranih fitopatogenih bakterija u in vitro uslovima. Prema dobijenim rezultatima, od ukupno 52 testirana izolata iz roda Bacillus, samo 6 je inhibiralo porast fitopatogenih bakterija i to samo iz roda Xanthomonas. Rezultati ispitivanja efikasnosti gljive T. harzianum su ukazali na mogućnost delovanja ove gljive na bakterije iz roda Pseudomonas i Xanthomonas, ali ne i na druge rodove fitopatogenih bakterija testirane u ovom radu. Dalja istraživanja treba bazirati na proučavanjima antimikrobne aktivnosti testiranih agenasa prema fitopatogenim bakterijama u in vivo ogledima....
