【 摘 要 】

The interactions of glyphosate and one adhesive spreading (concentrate of alcoholphenols with ethene-oxide and organic sulfonates) in reducing the surface tension and controlling Brachiaria decumbens and Panicum maximum were evaluated. It were used comercial products with 360 g a.e/l and 466 g i.a./l, respectivelly. To achieve similar control levels, the herbicide rates should be 24,05% higher for the second species. The herbicide reduced the effect of the surfactant on surface tension. The concentration of 0,1 % (c.p.) of the surfactant maximized the efficacy of glyphosate in controlling the two grasses.
