Abstract
An important place in the set of measures aimed at increasing the yield of maize is occupied by the methods of using fertilizers, herbicides and growth regulators. The yield of maize is largely determined by the phytosanitary state of crops. Maize has an average competitiveness and is sensitive to the presence of an excessive amount of weed-field component in agrocenoses. The article presents the results of three-year studies on the use of the pre-emergence herbicide DualGold and the postemergence herbicide Elumisna in various agrophonics, and shows their role in reducing the weediness of crops in the early maturing hybrid of maize Ladoga 181 MB. The possibility of using the growth regulator Zircon using herbicides has been studied. The observations showed that three weeks after the application of the post-emergence herbicide, the combined use of herbicides had a more effective effect on the state of maize crops - the total weediness decreased by 77.3 ... 79.1%. In the same variants, weeds accumulated the smallest dry biomass - 14.4 ... 17.8 g against an unfertilized background and 23.8 ... 25.1 g when applying mineral fertilizers. For harvesting, the greatest biological efficiency was also noted with complex herbicide treatment - 53.7 ... 62.3%. A significant decrease in the dry weight of weeds was established due to chemical weeding: against an unfertilized background by 7.9 ... 9.1 times, with fertilization - by 4.2 ... 6.9 times. The complex application of the growth regulator Zircon with herbicides contributed to a decrease in the number and weight of weeds by the time of harvesting maize, did not increase the adaptation of weeds to the effects of chemicals.
