摘　　要：70％氟唑磺隆WDG是防除春小麦田间杂草的新型除草剂,为明确其田间使用的除草效果及对小麦的安全性,进行了田间药效试验.结果表明,70％氟唑磺隆WDG在春小麦田间应用能有效防除禾本科杂草,使用剂量以45-60 ml/hm^2为宜,在春小麦3～5叶期、双子叶杂草1～8叶期每公顷兑水300 kg茎叶喷雾.对供试春小麦青春38号品种安全,使用后增产4.02％～5.06％.70% Flucarbazone WDG is a new herbicide for controlling weeds in spring wheat fields. Field trial was conducted in order to clarify its effect of weed controlling and safety to the spring wheat. The results showed that 70% Flucarbazone WDG control could effectively several kinds of grassy weed, its normal dosage was 45 - 60 ml/hm2in the term of 3 ~ 5 leaves and broadleaf at 1 - 8 leaves with 300 kg water. Applied 70% Flucarbazone WDG was safety to the spring wheat variety Qing - chun 38 and the yield of wheat were in- creased by 4.02% -5.06% than CK.
