Aspergillus flavus is the main producer of aflatoxin B1, one of the most toxic contaminants of food and feed. With global warming, climate conditions have become favourable for aflatoxin contamination of agricultural products in several European countries, including Serbia. The infection of maize with A. flavus, and aflatoxin synthesis can be controlled and reduced by application of a biocontrol product based on non-toxigenic strains of A. flavus. Biological control relies on competition between atoxigenic and toxigenic strains. This is the most commonly used biological control mechanism of aflatoxin contamination in maize in countries where aflatoxins pose a significant threat. Mytoolbox Af01, a native atoxigenic A. flavus strain, was obtained from maize grown in Serbia and used to produce a biocontrol product that was applied in irrigated and non-irrigated Serbian fields during 2016 and 2017. The application of this biocontrol product reduced aflatoxin levels in maize kernels (51–83%). The biocontrol treatment had a highly significant effect of reducing total aflatoxin contamination by 73%. This study showed that aflatoxin contamination control in Serbian maize can be achieved through biological control methods using atoxigenic A. flavus strains.

Bacteria from Enterobacteriaceae family (SRE) are significant problem in plant production, not only during vegetation, in the field, but also during storage and marketing of agricultural commodities. Species P. carotovorum subsp. brasiliense (Pcb) is a newly identified member of Enterobacteriaceae family. It causes soft rot of different plant species, including root vegetables. Pcb is described as a new subspecies of P. carotovorum due to differences in phenotypic and genotypic characteristic, more pronounced virulence and aggressiveness. Patohogenicity of this bacterium is based on the production of several enzymes: pectatliase, polygalacturonase, cellulase and proeteases. The aim of this study was to determine whether and at which rate Pcb isolates originating from potato plants exhibit pectolytic activity on root of different root vegetable species - carrot, radish, celery, kohlrabi and beetroot. The obtained data confirmed wide host range of the bacterium Pectobacterium carotovorum subsp. brasiliense, but pointed to significant differences in pectolytic activity on different species of root vegetables (carrot, radish, celery, kohlrabi), while on beetroot tested Pcb isolates did not exhibit pectolytic activity. Moreover, on same species of root vegetables different levels of pectolytic activity of tested Pcb isolates were recorded.

Fitopatogeni virusi prouzrokuju oboljenja biljaka koja često dovode do značajnih ekonomskih gubitaka. Viroze, poput mikoza i bakterioza, predstavljaju jedan od limitirajućih faktora poljoprivredne proizvodnje. Zbog višestruke mogućnosti zaraze postali su široko rasprostranjeni. Pritom, glavni način prevencije i borbe protiv virusnih infekcija jeste proizvodnja i upotreba zdravog sadnog i setvenog materijala. Kako su gubici kod voćarskih biljnih vrsta znatno veći nego kod ratarskih i povrtarskih (visoka cena sadnog materijala, podizanja i nege zasada), veoma je bitno pravovremeno sprovoditi preglede biljnog materijala i primenjivati metode rane detekcije virusa. Time se mogu izbeći štetni efekti virusnih zaraza. Među najznačajnijim virusima koštičavog voća javlja se virus nekrotične prstenaste pegavosti koštičavog voća (PNRSV). Zbog široke rasprostranjenosti ovog virusa i njegovog razarajućeg potencijala pimenjuju se razne metode dijagnostike. U ovom radu prikazane su metode detekcije PNRSV na osnovu specifičnosti proteinskog omotača (ELISA i DIBA) i metode detekcije datog virusa na osnovu nukleinske kiseline (RT-PCR). koštičavo voće; PNRSV; štetni efekti; metode dijagnostike; ELISA; RT-PCR

Emerging mycotoxins such as moniliformin (MON), enniatins (ENs), beauvericin (BEA), and fusaproliferin (FUS) may contaminate maize and negatively influence the yield and quality of grain. The aim of this study was to determine the content of emerging Fusarium mycotoxins in Serbian maize from the 2016, 2017, and 2018 harvests. A total of 190 samples from commercial maize production operations in Serbia were analyzed for the presence of MON, ENs, BEA, and FUS using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The obtained results were interpreted together with weather data from each year. MON, BEA, and FUS were major contaminants, while other emerging mycotoxins were not detected or were found in fewer samples (<20%). Overall contamination was highest in 2016 when MON and BEA were found in 50-80% of samples. In 2017 and 2018, high levels of MON, FUS, and BEA were detected in regions with high precipitation and warm weather during the silking phase of maize (July and the beginning of August), when the plants are most susceptible to Fusarium infections. Since environmental conditions in Serbia are favorable for the occurrence of mycotoxigenic fungi, monitoring Fusarium toxins is essential for the production of safe food and feed.
