“…However, it is not registered in Serbia. The biocontrol strain B. velezensis QST713 was chosen for a correlation test with B. subtilis Ch-13, the newly introduced strain with antifungal and phytostimulating characteristics, which has been registered as a microbiological fertilizer, fungicide and wheat seed disinfectant in the Russian Federation, Kazakhstan and Moldova (Chebotar et al, 2009;Kayin et al, 2015). Both Bacillus strains were examined for their impact on mushroom yield and efficacy against T. aggressivum f. europaeum from Serbia, when applied to mushroom casing soil and in comparison with the fungicide prochloraz manganese in a mushroom growing room.…”

The impact of a biofungicide based on Bacillus subtilis Ch-13 on mushroom yield and efficacy in suppression of Trichoderma aggressivum f. europaeum T77 from Serbia was estimated in comparision with a similar microbial fungicide, Bacillus velezensis QST713, and the chemical fungicide prochloraz manganese. The biofungicide B. velezensis QST713 is registered for treatments of mushrooms and other crops in many countries but it is not currently available on the Serbian market. The tested B. subtilis Ch-13 fungicide enhanced mushroom yield 12%, compared with an uninoculated control, and notably more than B. velezensis QST713 applied at its higher test concentrations. Regarding the efficacy of the biofungicides in control of the compost pathogen T. aggressivum f. europaeum, B. subtilis Ch-13 applied in concentration of 3 × 10 8 CFU per m 2 showed higher efficacy than the higher concentrations (5 × 10 9 and 1 × 10 10 CFU per m 2) of B. velezensis QST713. The biofungicide based on B. subtilis Ch-13 should be further investigated regarding its different modes of application to ensure better efficacy in disease control as it showed beneficial features in both promoting A. bisporus production and suppressing the growth of the aggressive compost pathogen T. aggressivum, the causal agent of devastating green mould disease.

“…La principal forma de control de los hongos causantes de podredumbres en frutas y hortalizas es mediante la aplicación de fungicidas químicos 2,24 . Sin embargo, la presencia de hongos patógenos resistentes a la acción de los fungicidas derivados de síntesis química y la necesidad de contar con alimentos inocuos 22,24 ha motivado la búsqueda de medidas alternativas al uso de agroquímicos que ayuden a reducir la presencia de hongos causantes de enfermedades en etapa productiva, sin afectar la salud del consumidor 7 .…”

The effect of phenolic and carotenoid extracts from chiltepin fruits on mycelial growth and the inhibition of conidial germination of Alternaria alternata and Fusarium oxysporum were investigated in the present work. Phenolic extracts inhibited mycelial growth of A.alternata by 38.46%, and significantly reduced conidial germination on the fifth day after treatment to 92% in relation to control. No significant changes were observed in the inhibition of mycelial growth in Fusarium oxysporum; however, the number of germinated conidia was reduced, showing 85% inhibition five days after treatment in relation to control. Moreover, carotenoid extracts showed 38.5% inhibition of mycelial growth and 85.3% inhibition of conidial germination of A.alternata, five days after treatment. Carotenoid extracts showed less inhibition of mycelial growth (20.3%) in F.oxysporum, with respect to A.alternata; while there was greater inhibition of conidial germination (96%) on the fifth day after treatment. Phenolic and carotenoid extracts from chiltepin may be a promising alternative as a natural fungicide against fungi of agricultural importance.

“…When inoculating tomatoes, they reduced the number of plants affected by phytopathogenic F. oxysporum by 2.5 times, the number of fungi on the roots was by 6.9 times lower than in the variant without inoculation with this strain. This strain was isolated from the chernozem soil of the Republic of Moldova [17]. Another strain of Ch-13 formed the basis of Bisalbisan, registered as a fungicide of etched wheat [18].…”

Aim. The article deals with the results of research, the aim of which was to determine antifungal activity of the strains Bacillus and Streptomyces genera, in relation to phytopathogenic fungi, widely distributed in Moldova. Methods. Strains were grown on classical agar media, the antifungal activity was determined by the method of agar blocks with test cultures -phytopathogenic fungi. Biological standard was the bacterium B. subtilis 26D. In the experiments on the germination of A. alternata conidia, 5 bacterial cultures grown in liquid nutrient medium No. 2. Results. It is established that all bacteria of genus Bacillus exhibit antifungal activity against test cultures, but in varying degrees. The growth of B. cinerea and F. oxysporum was least inhibited. Strain B. subtilis S4 most actively suppressed the growth of S. sclerotiorum. Strain Streptomyces sp. 10 is able to completely suppress the growth of A . alternata and B. cinerea, and the strain S. sp 9 completely suppressed the growth of S. sclerotiorum. Strains 9, 12, and 66 actively inhibited growth of F. culmorum (the radius of the zones was 16.0−20.0 mm), and strain S. sp. 185 against F. oxysporum (zones up to 28.0 mm). The strongest inhibitory effect on the germination of A. alternata conidia had strain S2. Conclusions. A comparative assessment of the antifungal activity of B. subtilis revealed a strain with the most pronounced antifungal properties. The investigated liquid cultures of bacteria of the genus Bacillus exhibited a special fungicidal effect on the germination of A. alternata conidia. Among 7 strains of streptomycetes tested, particular interest had S. sp. 10, capable to completely suppressing the growth of A. alternata and B. cinerea, and the strain S. sp. 9 -completely inhibits the growth of S. sclerotiorum, as well as the strain S. sp. 185 actively inhibited the growth of F. oxysporum and the strain S. sp. 10 − A. solani.
