摘要
田间小区试验验证了不同时期施用47%氯吡·丙·异WP对稻茬麦田杂草的防效及小麦的安全性。结果表明:47%氯吡·丙·异WP 2 250~4 500 g/hm^2小麦播后苗前、立针期至1.5叶期、3叶期喷雾处理对稻茬麦田菵草、荠菜、繁缕的株防效和鲜质量防效均高于90%,且对小麦安全。
The efficacy and selectivity of halosulfuron-methyl · pretilachlor · isoproturon 47% WP to rice-stubble wheat was investigated in a field experiment.The formulated mixture at 2250~4500g/hm2 provided above 90%pre-e-mergence control of Beckmannia syzigachne,Stellaria media,and Capsella bursa-pastoris based on visual assessment and fresh weight,at needle to 1.5 leaf-stages and 3 leaf-stages of wheat with selectivity to wheat.
