Abstract

In open ground conditions of the Rostov region, on improved natural soils, the effect of bioinsecticides for protection against the main pests of tomato and sweet pepper was assessed. The issues of the influence of the use of bioinsecticides on the size of the early and total yield of nightshade crops are considered. It was found that 4-fold treatment with the bioinsecticides Matrin Bio and Probrand contributed to the maximum suppression of melon aphids, spider mites and cutworms, but only provided approximately 50% protection against whiteflies. In general, the use of bioinsecticides for protection against pests, especially such as Probrand and Matrine Bio, is an effective technique that helps increase the yield of the early and overall harvest, and given the absence of harm from bioinsecticides, it makes it possible to obtain high-quality products. When choosing a varietal composition, pay attention to the tomato hybrid Makhitos F1 and the Rozovyy flamingo variety, and the sweet pepper varieties Knyaz’ serebryanyy and Zolotoe Chudo, bred by the Rostov CC and having a high adaptation potential to the local conditions of the Azov zone.
