摘要

Eleven field experiments were conducted during 1994 and 1995 to compare rhizomatous johnsongrass control and soybean yield with single POST applications of quizalofop-P, fluazifop-P, clethodim, and sethoxydim at costs of $9.88, 19.64, and 39.52/ha for each graminicide. Cost of the manufacturer's suggested use rate for these graminicides was approximately $29.64/ha, which corresponded to 0.09, 0.22, 0.14, and 0.27 kg ai/ha for these respective graminicides. When applied at a cost of $9.88/ha, quizalofop-P controlled rhizomatous johnsongrass more effectively than the other graminicides in five of 11 experiments.
