Herbicide efficacy and selectivity for burn-down and residual weed control in soybeans
DOI: 10.7824/rbh.v3i1.371
The effects of chlorimuron-ethyl at the rate of 10.0 g/ha applied alone and as tank mixture or in sequence with glyphosate, and diclosulam at the rate of35.2 g/ha plus glyphosate, as tank mixture, were studied for burn-down and residual control of Brachiaria p/antaginea (Link) Hitchc. and Bidens pilosa L. and for their safety to soybean in no-til. The study was conducted during the 2001/2002 growing season at the National Wheat Research Center of Embrapa in Passo Fundo, RS, Brazil, on a medium-textured soi!. The experimental design was a completely randomized block with four replications. Ali treatments were effective in desiccating B. pilosa. Chlorimuron-ethyl and diclosulam, applied alone, in mixture or in sequence with glyphosate provided season long weed control. No crop injury was observed and there was no effect on grain yield.
