| 摘 要： | 生物测定结果表明：P0603是一种广谱除草化合物,对多种阔叶杂草的防除活性高于磺草灵.在温室条件下,2.0 kg ai./hm^2和5.0 kg ai./hm^2 P0603土壤处理的除草效果优于茎叶处理,对婆婆纳、苘麻、播娘蒿、黑麦草、雀麦等的防效均达100%.田间试验表明,P0603在2.5 kg ai./hm^2剂量下,茎叶喷雾能防除窃衣、蛇莓、藜、荠菜、葎草、夏至草、卷耳,鲜重抑制率达85%以上. |

| Abstract: | The bioassay results showed that new compound P0603 could control a broad spectrum of grass and broadleaf weeds.In greenhouse,at dosage of 2.0 kg ai./hm2 and 5.0kg ai./hm2,the inhibitory of P0603 applied pre-emergence reached 100% to Veronica didyma Tenore,Abutilon theophrasti Medic.,Descurainia sophia(L.) Schur.,Lolium multiflorum Lam.and Bromus japonicus Thunb.Soil applications of P0603 provided a better weed control than foliar applications.In field trials,30 days after treatment(DAT),foliar sprayed P0603 at dosage of 2.5kg ai./hm2 performed a fresh-weight controlling above 85% to Tonilis scabra(Thunb.) DC.,Duchesnea indica(Andrews) Focke,Chenopodium album L.,Capsella bursa-pastoris(L.) Medic.,Humulus scandens(Lour.) Merr.,Lagopsis supine(Steph.) Ik.,Cerastium arvense L. |
