验证了12%烟嘧·氯氟吡氧乙酸油悬浮剂的田间使用效果,在夏玉米苗后3～5叶期茎叶处理,施药后3d,玉米叶片上出现点状或块状黄斑,药后7d左右开始恢复,对玉米生长及结实无不良影响,对玉米安全。药后10d,12%烟嘧?氯氟吡氧乙酸油悬浮剂180、216、270、432ga.i./hm2对狗尾草、马唐、铁苋菜、苘麻、异型莎草等杂草总的株防效分别为74.3%、79.1%、81.2%、87.4%;药后30d,株防效分别为91.2%、92.8%、94.1%、97.4%,鲜重防效分别为91.3%、92.1%、96.3%、98.8%,对一年生杂草防效显著。
The field effect of 12% nicotinyl fluroxypyr oil suspending agent was validated. The stems and leaves were treated 3 to 5 leaf stage after summer maize seedling emergence, dotted or massive macula appeared on the maize leaves 3d days after spraying, About 7 days after the drug began to recover, no adverse effects on the growth and fruiting of corn, corn safety. After 10 days of treatment, 12% of the total nicotinic acid-flupiroxcide was 180,216,270,432ga.i./hm2 against the total strains of Weeds such as Setaria viridis, Crabgrass, Iron amaranth, Cannabis sibiricus, Cyperaceae The control effects were 91.2%, 92.8%, 94.1% and 97.4% respectively, and the fresh weight control effects were 91.3%, 92.1% and 96.3 %, 98.8%, significant control effect on annual weeds.
