【 摘 要 】

In a field trial carried out in 1975/76, a diuron mixtu re with MSMA and another with paraquat was tested on broadleaved weeds in cotton crops. The applications were done in postemergence, directed-spray, in two different periods. The broadleaved weeds observed in the trial were Acanthospermum australe , Borreria alata, Richardia brasiliensis, and Sida spp, also the grass Digitaria sanguinalis.Best results were obtained with the mixture of 0,60 kg/ha of paraquat with 0,60 kg/ha of diuron, and 2,70 kg/ha of MSMA with 0,40 kg/ ha of diuron, or 2,00 kg/ha of MSMA with 0,30 kg/ha of diuron.All the treatments caused sl ight symptons of toxic ity in cotton, which disappeared later and did not damage the production.
