Изучение эффективности осенней обработки зерновых культур гербицидом морион

Abstract

A limited assortment of herbicides on cereals, which have a wide range of action and are used in the autumn period, determines the relevance of their search and study. The purpose of conducting a series of experiments with the herbicide Morion was to study its efficiency in conditions of three soil-climatic zones of the Russian Federation. Small plot field experiments were established in accordance with the «Guidelines for field test of herbicides in crop production» (1981) on winter wheat in the Ryazan and Moscow regions and in the Krasnodar territory, and on winter rye in the Volgograd and Kaluga regions. In five of the six regions, the decrease in the total number of weed plants at the Morion herbicide use was higher than that at standard. The use of herbicide Morion is most effective in sowing winter cereal crops, where annual dicots and annual grass weeds grow. The carried out researches have allowed to recommend the herbicide Morion to the state registration in the Russian Federation.
