- 摘要:
- 80%甲羧除草醚可湿性粉剂是触杀型芽前土壤处理剂,为确定最佳施用时期及剂量,进行了其防除春大豆田杂草安全性及药效的试验。结果表明:在春大豆田播后苗前进行土壤均匀喷雾,对大豆出苗及生长安全,施药后40 d对一年生阔叶及禾本科杂草的株防效均大于90%,鲜重防效均大于95%,并且持效期长达45 d以上。适宜施药时期为春大豆播后苗前(播后3~5 d),施用制剂量为1 125~1 275 g·hm-2(有效成分用量900~1 020 g·hm-2)。
- Abstract:
- 80% Bifenox WP is the tag bud soil treatment agent,for the purpose of defining the best applying stage and dosage,its security test and efficacy for controlling weeds in spring soybean were conducted.The results showed that it was safe for soybean emergence and growth when spraying on soybean field after sowing and before emergence.After spraying 40 d,the strain control effect of annual grass and broadleaf weed was more than 90%,the fresh weight efficiency was more than 95%,and persistence over more than 45 days.Suitable spraying period in the spring soybean field was after sowing and before emergence(after sowing 3~5 d),the application preparation volume was 1 125~1 275 g·hm-2(active ingredient 900~1 020 g·hm-2).
