46%丁噻隆悬浮剂对后茬作物的安全性试验

Safety experiment of tebuthiuron 46% SC on succeeding crops

采用室内盆栽试验的方法,研究了46%丁噻隆悬浮剂土壤残留1个月后对后茬作物生长的影响及安全性。结果表明:在低剂量850 g/hm2(a.i)下,可以安全种植荷兰豆和花生;在中剂量1 700 g/hm2(a.i)下,可以安全种植荷兰豆;在高剂量2 550 g/hm2(a.i)下,菜心、菠菜、青菜和白菜均产生很严重的药害,不能种植,玉米和花生产生严重药害,不能种植,而对荷兰豆产生相对较轻的药害,最好不种植。

The aim of this study was to determine the effect of Tebuthiuron 46% SC on succeeding crops for 1 month using the Indoor pot test method after application. The results showed that at the low rate of 850 g/h㎡（a.i.）, snow bean and peanut were not injured. At the middle rate of 1 700 g/h㎡ （a.i.）, snow bean was not injured. At the high rate of 2 550 g/h㎡ （a.i.）, flowering cabbage, spinach, vegetables and Chinese cabbage should all be avoided. Sensitive crops such as corn and peanut were injured relatively severely, and should not be planted. Relatively sensitive crops snow bean showed slight injury and should nrobahlv not ha nlnntarl
