Development of new protective means for increasing productivity of organic crop

Currently, one of the urgent issues facing agriculture is its biologization. Biologization is the maximum or complete substitution of chemicals used in crop production for environmentally friendly ones to humans and the environment. Therefore, the development of new plant protection products is of great practical importance, because they are an alternative to chemical pesticides and can almost completely abandon their use. The aim of this work was to study the effectiveness of the influence of biologically active plant components - garlic phytoncides (Alium sativum), celandine flavonoids (Chelidonium majus), fern phenolic compounds (Dryopteris filix mas), tomato glycoalkaloids (Solanium lucopersicum) (tomato) and potato (Solanium tuberosum) (solanine) on the survival of Colorado potato beetle larvae on potato growing organs. The studies were conducted in the field conditions of the Bolkhov region, Oryol region. To study the effect of herbal preparations, the Nevsky potato variety most populated by the Colorado potato beetle was selected. The treatment of experimental potato bushes was carried out with plant extracts at a concentration of 10-2 and 10-7%, the control with distilled water. Repetition was 3 times. As a second control, the Commander industrial pesticide was used. A day later, a visual assessment was performed on the effect of the insecticidal action on the larvae of the insect pest. The methods used were: observation, counting, analysis, synthesis. As a result of studies, it was found that garlic volatile and phenolic compounds of fern possess the highest insecticidal efficacy against pest insect larvae, which can form the basis for the creation of new plant protection products.
