The greening factor in the application of herbicides is the targeted use of herbicides, and increasing productivity, generally by reducing the rate of flow of the working fluid. The aim of our study was to assess the influence of the rate of flow of the working fluid and size of nozzles on the efficiency of herbicides in winter wheat. The studies were conducted in 2019 at the experimental station of the State budgetary educational institution “Stavropol state agrarian University”. In winter wheat studies were conducted on cultivar Tanya, the forecrop - sunflower. We studied the biological efficiency of the experimental tank mixture of herbicides c compared with the tank mixture of herbicides used at the experimental station. The results showed that the decrease in consumption rate of working solution to 50-100 l/ha and use nozzles caliber ST 110-01 and ST 110-02 has a negative effect: firstly on the expression of herbicidal activity, which leads to the increase of the period of oppression and destruction, as the cereals and dicotyledonous weeds; secondly on the species sensitivity of weeds reducing it from 2 to 7 %; third on the biological efficiency of herbicides, reducing it by 2-3% in the number of destroyed weeds and up to 6% on their biological ground.

Currently, one of the promising areas of applied chemistry is research and development of composite absorption materials used as sorbents with a wide range of action, as well as media for biologic preparations and drugs. We have performed research on the development of composite organic silica chitosan-silica based materials with certain composition and biochemical action. Silica was used as the main component, and chitosan -as bio-compatible polymer in the composition of the composite sorbent.
