Efficacy of flumioxazin alone or in mixture with sulphosate to desiccate Ageratum conyzoides and Commelina benghalensis previous to soybean
DOI: 10.7824/rbh.v1i2.323
Two experiments were carried out to test the efficacy offlumioxazin to desiccate Ageratum conyzoides and Commelina benghalensis previous to soybean planting. One of them tested doses of the herbicide alone and the other tested doses of flumioxazin in mixture with sulphosate. Flumioxazin (30, 40 and 50 g/ha) mixed with mineral oil (0,5 and 1,0%) showed an excellent control (more than 90%) of Ageratum conyzoides and Commelina benghalensis. The mixture flumioxazin (20 or 25 g/ha) + sulphosate (960 or 1,440 g/ha) showed an excellent (90-99%) or acceptable (80-89%) control of Ageratum conyzoides and Commelina benghalensis, respectively. No toxicity was observed in the soybean plants by any treatrnent involving flumioxazin.
