Shita O. The ecological substantiation potatoes protection (Solanum tuberosum L.) from harmful organisms in the Forest-steppe of Ukraine

The object of research is an environmentally safe system for protecting potato planting from harmful organisms. ... Purpose - Development of environmentally sound measures for protecting potatoes from harmful organisms, based on the rational use of chemical and biological preparations in the conditions of the forest-steppe of Ukraine. Based on long-term monitoring, the species composition of weeds, pests and pathogens that cause potential risks in the potato agrocenosis has been established. The impact of biological products, herbicides, insecticides and fungicides on treatment, spraying and joint and consistent use to protect potato agrocenosis from pests at the ecological and economic levels has been assessed. The parameters of ecotoxicological characteristics of pesticides used to protect potatoes from weeds, pests and diseases have been determined, and the classification according to the degree of danger has been carried out. It has been established that when using pesticides, the hazard index according to AETI is 0.02–0.3, does not exceed 1 and is low-risk. An ecologically safe system of potato protection against pests has been developed, which is based on minimizing the use of pesticides and the inclusion of bioagents to obtain quality products. The obtained research results are of practical importance for the preservation of the natural environment and the reduction of the negative load on the agroecosystem, in order to obtain environmentally friendly products of potato tubers. Key words: ecological justification, potatoes, harmful organisms, chemical and biological preparations, ecologically safe protection system.
