Abstract

Experiments were conducted in 1988 and 1989 at four sites in Virginia to test weed control efficacy in double-crop, no-till soybean production systems with reduced rates of nonselective herbicides. Chlorimuron plus linuron at 0.04 plus 0.46 kg ha-1 gave more than 94% control of five weed species, but only 81 to 86% control of three weed species. Tank mix additions of reduced rates of either glyphosate, HOE-0661 or paraquat to the chlorimuron plus linuron treatment increased large crabgrass and common ragweed control.
