摘要
研究50%乙草胺乳油、20%百草枯、33%施田补乳油、41%草甘膦异丙胺盐水剂4种化学药剂防治蒜田杂草效果及对大蒜的安全性,结果表明:4种药剂防治田间杂草鲜重防效均在70%以上,其中20%百草枯和41%草甘膦异丙胺盐水剂防治效果较佳,但易对大蒜产生药害,并减少产量,所以建议谨慎使用,而50%乙草胺乳油和33%施田补乳油可以用于蒜田中的杂草防治并进行推广。
The control effect and security of 50% acetochlor EC ,20% paraquat,33% pendimethalin EC ,41% glyphosate IPA against weeds in garlic field were studied.The results showed that four herbicides control effect were more than 70% ,and the effects of 20% paraquat and 41% g[yphosate IPA were better,but they were easy causing the garlic injury,and reducing production,so it was recommended to be used with caution.50% acetochlor EC and 33% pendimetbalin EC could be used to control weed in garlic field and promote.
