Abstract
The effect of the biofungicide BFTIM KS-2, Zh on the development and spreading of the Alternaria alternata fungus on vegetable crops (tomato, pepper, eggplant) was studied using classical and modern methods of phytosanitary monitoring. The research was carried out in Krasnodar region in the Pavlovsky District, on the production fields of the ZAO Yubileinoye. To assess the development and spreading of the disease, the classical visual method was used, as well as a modern method for determining the congestion rate of plantings using the OZR-1mp spore trap.The article presents data on the development and spreading of A. alternata, the number of fungal spores on vegetable crops before and after treatments with the biofungicide. It was found that the use of the biological product reduces the development and spreading of the phytopathogen. Its influence is the most effective on tomato and eggplant crops. Also, in the course of research, the possibility of using a spore trap for monitoring Alternaria on vegetable crops has been shown.
Highlights
Vegetable crops provide the basis of the daily human diet, being a rich source of vitamins, enzymes, and mineral salts
The aim of the research was to study the effect of a biological fungicide on the development and spreading Alternaria alternata fungus on vegetable crops using classical and modern methods
Spores of the A. alternata fungus were detected on all studied crops using an air sampler (Fig. 1, Table 1)
Summary
Vegetable crops provide the basis of the daily human diet, being a rich source of vitamins, enzymes, and mineral salts. For example, Krasnodar Krai is one of the leading regions of Russia in terms of area and production of tomato in open ground. In 2020, according to Rosstat, 893.4 thousand tons of tomato were produced in the industrial sector of vegetable growing in Russia on an area of 17.9 thousand hectares. In Krasnodar Krai, 9.08 thousand tons of tomato were produced on an area of 0.47 thousand hectares (ABCenter, 2020). Pepper and eggplant are highly susceptible to the influence of abiotic and biotic factors that affect the yield and product quality. These crops are damaged with up to 200 diseases caused by viruses, bacteria, nematodes and fungi. The most common and economically significant disease is considered to be alternaria, which is caused by Alternaria fungi [5,6,7,8,9,10]
