摘要
采用田间小区试验方法,测定70%氟唑磺隆WDG对春麦田杂草的除草活性及其对后茬作物油菜、蚕豆、豌豆的影响。结果表明:在春小麦3~5叶期茎叶处理,70%氟唑磺隆WDG 30.00~45.00 g/hm^2(有效量21.0~31.5 g/hm^2),对野燕麦防除效果达85%左右,对1年生阔叶杂草防除效果达75%以上,对春小麦及对油菜、蚕豆、豌豆3种后茬作物均表现安全。
The present study aimed to determine the efficacy of the herbicide 70% fluoxazole sulfonon WDG in controlling annual grasses and broadleaf weeds in the spring wheat field, and to evaluate its influence on the safety of the succeeding crops （rape, broad bean, and pea）. A field plot experiment was conducted in a spring wheat field in Xining, and 70% fluoxazole sulfonon WDG was applied at 30.00～45.00 g/hm2 （containing 21.0～31.5 g active ingredient/hm2） on May 12, 2016, when wheat seedlings were at 3～5 leaf stage. Results showed that 70% flucarbazone-Na WDG attained the efficacy about 85% in controlling wild oats and the efficacy higher than 75% in controlling annual broad-leaved weeds. On the other hand, its application did not produce a negative effect on the safety of spring wheat and its three succeeding crops： rape, broad bean, and pea.
