Case study: Influence of probiotics-based products on phytopathogenic bacteria and fungi in agrocenosis
MetadataShow full item record
In recent years bacterial diseases of agricultural plants have reached a new level of epiphytoty and they appear as an essential factor that influences crop yield. It is important to use products, which provide the eradication of pathogenic agents and the prevention of their development and propagation. The objective of our study is to define the effect of probiotics, based on Bacillus subtillis, on bactericidal and fungicidal activities, and to develop the recommendations for probiotics application in a biological system of plant protection. The results show that studied solutions Sviteco-PPW, Sviteco-OPL and Sviteco-Agrobiotic-01 affect phytopathogenic bacteria. Sviteco-Agrobiotic-01 either is the most active product, in its native state or diluted. It has demonstrated high antagonizing activity against all studied phytopathogenic bacteria. Hence, Sviteco-Agrobiotic-01 has the best potential to be used in the biological protection system of grain crops, grain legumes, vegetables from the most dangerous and widely spread pathogenic bacteria. Research results don't show a significant effect of studied probiotics on phytopathogenic fungicidal activity.
