Description
Summary:The impact of bioformulations on the development of fungal diseases and the productivity of tomatoes was studied. Microorganisms of the genera Azotobacter, Bacillus, Pseudomonas, Streptomyces, and Trichoderma were used as bioagents. Their protective effect was compared with the effectiveness of chemical fungicides. The majority of bioformulations actively inhibited the spore germination of tomato pathogens Alternaria solani and Phytophthora infestans. In greenhouse experiments, biological preparations provided a protective effect at the level of 33.2%-70.1% against early dry spot and 34.3%-65.5% against late blight of tomatoes. The use of bioformulations in the field experiments effectively controlled tomato diseases and improved productivity and fruit quality. The highest protective effect against early dry spot was observed with the use of bioformulations Avercom, Biophosphorin, Haupsin, Planriz, and Trichodermin. Biophosphorin, Azotobacterin, Azostrept, and Haupsin were more effective against phytophthora. Usage of bioformulations provided the 19%-66% increase of healthy fruit harvest of different varieties of tomatoes.
