Okrushko Svetlana Evgenivna − Candidate of Agricultural Sciences (PhD), Senior Lecturer of the Department of Botany, Genetics and Plant Protection of Vinnitsia National Agrarian University (210083, Vinnitsia, Soniachna Str.3, e-mail: email@example.com).
The article describes the influence of soil and insurance herbicides on the number, weight of weeds in corn crops and its yield. On the plots where herbicides were applied, the effect of the growth regulator Zeastimulin on corn plants and its productivity was simultaneously studied. Three years of research have shown that the degree of weediness of corn crops is high. In the agrophytocenosis of corn a mixed type of weediness was formed, in which late spring weeds predominated. After application of Adengo herbicide (soil, 0.35 l / ha), weed accounting showed a 90% reduction in weed agrophytocenosis of corn, compared to the weediness of the control variant. Consistent application of pre-emergence and post-emergence herbicides best controlled weed numbers and reduced their negative effects in maize agrophytocenoses. Controlling the number of weeds in maize agrophytocenoses before the emergence of seedlings with the help of soil herbicide Adengo (0.5 l / ha) provides an increase in grain yield for an average of three years of research by 3.5 t / ha. Consistent use of Adengo (0.35 l / ha) and MaisTer Power (1.25 l / ha) in the corn phase of 4-5 leaves before sawing gave a grain increase of 4.4 t / ha. Preventing the harmful effects of weeds by chemical means has saved a significant part of the potential yield of corn grain. In the variants, where herbicides were used compatible with the growth regulator Zeastimulin, there was a decrease in weed mass and an increase in grain yield by 7.8% in the variant, where the soil herbicide Adengo 465 (0.5 l / ha) was applied before the emergence of seedlings, and by 6.8% in the variant with consistent use of Adengo 465 (0.35 l / ha) before sowing corn and MaisTer Power herbicides (1.25 l / ha) during the phase of 4-5 leaves in corn.
