| 摘 要： | 为了明确90%乙草胺乳油在华南地区花生田的应用效果，采用大田药效试验的方法，对90%乙草胺乳油防除春秋两季花生田杂草的效果、安全性及最佳使用剂量进行研究。结果表明：该药剂在花生播前苗后进行土壤处理，推荐使用剂量1080~1350 g(a.i.)/hm2，药后45天对牛筋草、马唐、稗草等一年生杂草的防效在80%以上，在春花生田使用发现，对小藜、繁缕防效较差，建议后期再次用药。在推荐使用剂量内对花生安全，高浓度会产生一定药害。从而，为90%乙草胺乳油在华南地区花生田的应用提供试验依据。

| Abstract: | The aim of this study was to evaluate the effect of 90% acetochlor EC on weeds in the spring and autumn peanuts field.The peanut safety and control efficacy of the weeds with 90% acetochlor EC was researched in South China.The results showed that,the control effect was up 80% 45 days on Eleusine indica L.Gaertn,Digitaria sanguinalis L.Scop,Echinochloa crusgalli with spraying 1080-1350 g（a.i.）/hm2 90% acetochlor EC before seedling emergence and after sowing of peanut,but it had a bad effect on Chenopodium serotinum L.,Stellaria media L.Cry.in spring peanut field.So it provided the theoretical basis of 90% acetochlor EC on the weed control in South China spring and autumn peanuts field and was safety on peanut with recommended dose. |
