摘要
分析了4%唑啉草酯·双氟磺草胺可分散油悬浮剂对小麦田杂草的防除效果及安全性评价。结果表明,4%唑啉草酯·双氟磺草胺可分散油悬浮剂对小麦地禾本科杂草、阔叶杂草等一年生杂草均有防效,对小麦安全。喷施剂量为54~120 g/hm 2的4%唑啉草酯·双氟磺草胺可分散油悬浮剂,喷药后45 d的总草株防效为71.7%~95.5%,喷药后45 d的鲜重防效为71.4%~96.7%。从药剂施用的经济性和安全性考虑,推荐4%唑啉草酯·双氟磺草胺可分散油悬浮剂54~66 g/hm 2,对水喷施药液作杂草茎叶处理。
This study analyzed the control effect and safety evaluation of 4%oxazolinol and diflufenazone dispersible oil suspension agent on weeds in wheat field.The results showed that 4%oxazolinol·diflufenazone dispersible oil suspension agent had control effect on annual weeds such as wheat weeds and broadleaf weeds,and it was safe for wheat.Spraying 4%oxazolinol·diflufenazone dispersible oil suspension agent at a dosage of 54-120 g/hm 2,the total grass plant control effect after spraying for 45 days was 71.7%-95.5%,after spraying 45-day fresh weight control effect was 71.4%-96.7%.From the economic and safety considerations of the application of the drug,it was recommended to use 4%oxazolinol·diflufenazone dispersible oil suspension agent 54-66 g/hm 2,and spray the solution with water to treat the stems and leaves of the weeds.
