摘要
采用小区试验方法进行了质量分数为15%磺草酮油悬剂防除玉米田杂草田间药效试验。结果表明:质量分数为15%磺草酮油悬剂在玉米三、四叶期施用,剂量为0 180～0 450kg hm2,稗草的平均防效为86 0%,对各种阔叶杂草总平均防效为77 4%,对杂草的鲜重平均抑制效果为78 5%,而且杀草谱广,防效持久,不影响后茬轮作。
The trails of 15% ICIA0051 oil suspension concentrate in controlling corn field weeds were conducted. The results showed that excellent weed control performance was achieved when ICIA0051 oil suspension concentrate was applied to corn at the 3～4 leaf stage and within the application dosage (0.18～)0.45 kg/hm^2. Its average control effect against barnyardgrass was 86.0%, its average control effect against various broadleaf weeds was 77.4%, and its average effect of inhibiting weed fresh weight was (78.5%.) 15% ICIA0051 OSC is a herbicide of a broad spectrum and a persistent control effect, and it doesn′t affect the succeeding crops.
