METHOD FOR CONTROLLING OF GOOSE GRASS IN WINTER WHEAT CROP

摘要

FIELD: agriculture, in particular, protection of winter wheat crops from goose grass.;SUBSTANCE: method involves using bacteriological mixture of herbicides of harmony and banvel (10 g/hectare + 300 ml/hectare) and adding surfactant-trend in an amount of 90-200 ml/hectare at flow rate of working fluid of 300 l/hectare; treating crops at tillering phase which is most sensitive phase for goose grass, in particular, during 2-3 whorl phase. Method allows 100% elimination of malicious weed of goose grass to be provided, total contamination to be reduced to 2 pcs/square km or 97.7% killing of accompanying weed plants and suppression of retained species by 93% to be enabled, and wheat yield to be increased by 32.8 hundredweight/hectare or 12.3 hundredweight/hectare of yield gain.;EFFECT: formation of high-quality grain, reduced expenses for protection of winter wheat crops from weedage, provision for return of investment, ecological safety for environment and other rotation crops.;1 tbl
