【 摘 要 】

This research was carried out in Selvíria-MS, Brazil, during the growing seasons of 1996/97 and 1997/98, using the soybean cultivar IAC-15. The experimental design was arranged in randomized complete blocks in a 3x3 and 4x4 factorial scheme during 1996/97 and 1997/98, respectively, with the factors being the products (desiccants) and timing of application. The desiccants sprayed were: paraquat, diquat and a mixture of paraquat + diquat at rates of 0.4; 0.3 and 0.2+0.15 in 1996/97 and the same treatments in 1997/98 added to ammonium glufosinate at 0.4 kg a.i. ha-1 in 1997/98. The timing of application was spaced every five days, starting from the soybean vegetative stage R6. The tested desiccants were efficient on the soybean desiccation ; it was possible to obtain grain harvest anticipation, without yield reduction, in a maximum period of seven days.
