The effectiveness of the use of analogue preparations with the active substance rimsulfuron on potatoes in the conditions of the Tyumen region

Abstract

Relevance. The study of the effectiveness of protection methods, herbicides with different content and composition of active substances, their influence on the crop, weed component, yield and related factors is important for clarifying the regulations for use, production decisions in the manufacture of preparations and their use.Methods. The study of the effect of various analogues of herbicides with the active ingredient rimsulfuron on weed suppression and crop development was carried out on the experimental field of the Research Institute of Agriculture of the Northern Trans-Urals, the northern forest-steppe of the Tyumen region under the conditions of 2021. The object of research was 4 preparations of herbicidal action from different manufacturers with the main active ingredient rimsulfuron 250 g/kg for use on potato crops to suppress weeds of perennial and annual cereal type and annual dicotyledonous type.Results. The initial study of the clogging of experimental plots before treatment with the studied herbicides showed the presence of an average number of processing showed the presence of a total number of weeds according to the variants of the experiment 60–70 pcs/m2 with a quantitative advantage of 4 types of weeds еchinochloa crus-galli, Elymus repens, Thlaspi arvense, Chenopódium álbum. On the variants of herbicide application, the mass of weeds was 8–20 times less and amounted to 20–55 g/m2. As a result of the use of the studied herbicides against weeds, a stable and high efficiency of 86–97% during the entire growing season on options Herbicide 3, 4.
