The effectiveness of the herbicide Lintur in the cultivation of millet varieties "Sputnik"

The growth of millet grain production is mainly limited by weed infestation of this crop. The peculiarity of the damage caused by weeds, compared to diseases and pests, is that they are more likely to be not parasites, but competitors of cultivated plants in sharing nutrients and minerals, light, and moisture. This, in turn, makes it easier to determine the direct damage caused to the crop by the weeds. Agrotechnical measures do not always give the expected effect, so the importance of herbicides for destruction of weeds in millet crops increases. In this regard, a highly effective herbicide with a wide spectrum of action against monocotyledonous and dicotyledonous weeds was selected. A systematic analysis of the contamination of millet crop variety “Sputnik” was carried out and the phases of plant development for the use of the Lintur herbicide were determined. During route surveys, the main weeds of millet were identified: juvenile weeds, which make up 88-92% of the total number, 8-12% were occupied by perennial species. On average, the composition of weeds in millet crops consisted of 26 species. The most common were: false wheat, lambsquarter goosefoot, barnyard grass, wild buckwheat, yellow foxtail, field milk thistle. Some types of weed vegetation belonging to the families of Poaceae, buckwheat family, pink family, goosefoot, family and violet family are widely distributed. For two years, the weed infestation of millet crops was 114 pcs/m2. The weed cenosis was dominated by wild buckwheat (11.8 pcs/m2), false wheat (18.8 pcs/m2), yellow foxtail (12.2 pcs/m2), barnyard grass (17.6 pcs/m2), lambsquarter goosefoot (15.6 pcs/m2). Mainly, the floristic composition of weeds in the millet agrophytocenosis was influenced by the main tillage, and to a greater extent by the use of the herbicide Lintur. The use of this herbicide reduced the composition of weed vegetation by 80-100%.
