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./hm2和5.0 kg ai./hm2P0603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./hm2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。
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./hm^2 and 5.0kg ai./hm^2 , 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./hm^2 performed a freshweight controlling above 85% to Tonilisscabra （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.
