Weed infestation in soybean agrocenosis depending on primary tillage practices and herbicide applications

Abstract

The highest level of weed control was achieved with the following treatment scheme: Hlifovit Extra SC, 3.0 l/ha (pre-emergence); Varyag SC, 4.0 l/ha (post sowing); Selenit Max, 0.6 l/ha (at the 2-4 trifoliate leaf stage of the crop); and Basagran, 2.0 l/ha + Komandyr, 0.2 l/ha (at the 6-8 trifoliate leaf stage of the crop). Under moldboard ploughing, the technical efficacy reached 98.0-99.0%, while under chisel and disk tillage, it was 95.0-95.9% and 95.7-97.0%, respectively.
