摘要：
Eight field experiments were conducted during 2013-2015 to determine the dose response of glyphosate-resistant Canada fleabane to preplant metribuzin in a tank mixture with glyphosate in soybean. The predicted metribuzin rates required to achieve 80%, 90%, and 95% visual control of glyphosate-resistant Canada fleabane were 659, 1093, and 1720 g a.i. ha(-1) at 4 weeks after application and 783, 1355, and 2237 g a. i. ha(-1) at 8 weeks after application, respectively.
