Abstract

It was established that in the agrophytocenosis of corn on the control variant (without introducing herbicides) a mixed type of debris was formed, in which a group of late spring weeds prevailed. After the introduction of the soil herbicide Adengo 465 (0.5 l / ha) on the sowing of maize weeds were 92% less compared to the contamination of the control experiment, where the chemical method was not used. The combination of the use of the soil herbicide Adengo 465 (0.35 l / ha) and the insurance herbicide Master Power (1.25 l / ha in the 4-5 leaf phase of the crop) in the agrophytocenosis of corn provided the qualitative control of the main weed species. At the time of harvesting in corn crops there were 97% less weeds compared with the control variant. The combined use of these herbicides has provided a high increase in the yield of corn grain - 4.8 t / ha.
