[目的]验证26.7%噻酮磺隆·异噁唑草酮悬浮剂对玉米田杂草的药效、杀草谱及对玉米的安全性。[方法]采用茎叶喷雾、定期调查的方法进行田间药效试验。[结果]药剂26.7%噻酮磺隆·异噁唑草酮悬浮剂的杀草谱较广,包括一年生禾本科杂草及大部分阔叶杂草。施药后30 d调查,其对各种杂草株数综合防效为89.0%~99.5%。鲜质量防效达94.5%~99.9%。[结论]26.7%噻酮·异噁唑SC适宜使用剂量为141.75~165.38 g a.i./hm2,对水375 L/hm2茎叶喷雾。
[Objective] The research aimed to verify the efficacy, the herbicide protection spectrum and the safety to corn of 26.7% Susceptible Susceptible Susceptible Susceptible Susceptible (Susceptible) to corn weeds. [Method] The field efficacy test was carried out by using stem-leaf spray and regular investigation. [Result] The 26.7% thiabendosulfuron and isoxaflutazole suspending agent had a broad spectrum of herbicidal activity, including annual grass weeds and most broadleaf weeds. 30 d after the application of the survey, the number of weeds on the comprehensive control effect was 89.0% to 99.5%. Fresh quality control effect of 94.5% to 99.9%. [Conclusion] The optimal dosage of 26.7% thiaisone / isoxazole SC was 141.75 ~ 165.38 g a.i./hm2, spraying 375 L / hm2 stems and leaves.
