摘要
480 g/L麦草畏水剂是一种新型的水剂型除草剂,为明确其用于防除春小麦田间杂草的效果及对小麦的安全性,进行了田间药效试验。结果表明,480 g/L麦草畏水剂能有效防除春小麦田间多种阔叶杂草,300～750 mL/hm2的使用剂量对春小麦安全,使用后增产3.47%～10.80%。推荐田间使用量为450～750mL/hm2,在春小麦3～5叶期、双子叶杂草2～8叶期每公顷对水300 kg茎叶喷雾。
Dicamba 480 g / L AS is a new herbicide for controlling weeds in spring wheat fields. Field trial was conducted to clarify its effect on weed controlling and its safety for the spring wheat. The results showed that Dicamba 480 g / L AS could control effectively several kinds of broadleaf weeds. The dosage of 300～750 mL / hm2was safe for the spring wheat. The yield of wheat were 3.47% ～10.08% more than that of CK. The normal dosage was 300 ～750 mL / hm2in the term of 3 ～5 leaves and broadleaf at 2～8 leaves with 300 kg water.
