摘要
30%毒氟磷可湿性粉剂,20%毒氟磷悬浮剂,30%毒氟·吗啉胍可湿性粉剂,防控南方水稻黑条矮缩病的效果进行了试验。结果显示:毒氟磷相关药剂对南方水稻黑条矮缩病有较好的防控效果,在水稻移栽初期预防,用药量270~340g a.i/hm^2,防效达到58.4%~74%,略优于对照药剂,其中20%毒氟磷悬浮剂340g a.i/hm^2效果最好。
The field efficacy tests were conducted on dufulin 30%WP,dufulin20%SC and dufulin and moroxydine hydrochloride 30%WP for the control of southern rice black streaked dwarf disease.The results showed that dufulin-based products could provide ideal control effect on southern rice black-streaked dwarf disease.In the early stage of rice transplanting,the control effect was found to be 58.4%~74%at the dosage of 270g ai/hm^2~340g ai/hm^2,which was slightly better than the control agent.Dufulin 20%SC at the dosage of 340g ai/hm^2 provided the best effect.
