Abstract

The use of adjuvants in chemical crop protection systems against harmful objects, including weeds, is one of the most substantial innovations in agricultural production. The study aimed to investigate the effectiveness of different rates of Peritera adjuvant in the system of pre-emergence herbicide protection of annual sunflower (Helianthus annuus L.) in the western forest-steppe. Research methods: field, laboratory, quantitative, mathematical and statistical to assess the reliability of the data obtained. Many years of research have shown that uneven distribution of precipitation (drought or excessive moisture) during sowing and in the early stages of crop development creates obstacles to the effective action of soil (pre-emergence) herbicides, and the addition of adjuvants to them has a positive effect on the growth, development and formation of sunflower seed productivity. In the conditions of the Western Forest-Steppe (Ternopil region), the best results when using pre-emergence herbicide protection of sunflower were recorded in the variant where Soranet, CE (propizochlor, 720 g/l) – 2.0 l/ha + Idaho, KS (terbutylazine, 500 g/l)  1.5 l/ha was applied, and Peritera adjuvant 0.2 l/ha was added to the specified tank mixture. The use of this soil protection scheme for the crop under study ensured the lowest number of segetal vegetation in the agrocenoses of annual sunflower. In addition, the highest chlorophyll content and low phytotoxicity of the used preparations in relation to cultivated plants were noted. The use of surfactants, which, on the one hand, prevent the movement of active substances to the lower horizons and, on the other hand, ensure better penetration into the soil during moisture shortages, can help to mitigate adverse factors. The results obtained are the basis for improving the elements of sunflower cultivation technology and will ensure a seed yield of 3.58 t/ha and can be used in agricultural formations in Ukraine
