摘  要:
[目的]明确氰氟草酯的除草效果、适宜的用药量以及对水稻秧苗的安全性。[方法]以50%二氯喹磷酸可湿性粉剂为对照药剂,通过田间药效试验研究了100 g/L氰氟草酯乳油不同剂量(90、120、150、180 g/hm2)对水稻秧田千金子、稗草等杂草的防除效果及对水稻秧苗生育的安全性。[结果]100 g/L氰氟草酯乳油用药量150 g/hm2时对水稻秧田抗性杂草——千金子具有很好的防除效果,施药后20 d除治千金子的效果达到98.3%,千金子生物鲜重抑制效果为98.7%,同时对稗草的除治效果为96.2%;100 g/L氰氟草酯乳油不同剂量对水稻生育安全。[结论]100 g/L氰氟草酯乳油是除治水稻旱育秧田千金子的优良除草剂,并可兼治稗草等1年生杂草。

摘  要:
[Objective] The aim was to make sure efficiency and safety of cyhalofop-butyl emulsifiable concentrate on controlling L. chinensis in rice seedling field. [Method]50% Quinclorac wettable powder was taken as control agent,and efficiency and safety of 100 g / L cyhalofop-butyl emulsifiable concentrate at different concentrations of 90,120,150 and 180 g / hm2 on controlling L. chinensis in rice seedling field were studied by field efficacy trials. [Result] 100 g / L cyhalofop-butyl emulsifiable concentrate at the dosage of 150 g / hm2 had good control effect on L.chinensis,and the control effect on L. chinensis reached 98. 3% in 20 days after treatment,and the inhibition effect on biological fresh weight was98. 7%,meanwhile the control effect on barnyard grass was 96. 2%. The use of 100 g / L cyhalofop-butyl emulsifiable concentrate was safe for the growth and development of rice. [Conclusion]100 g / L cyhalofop-butyl emulsifiable concentrate was suitable for controlling L. chinensis in rice seedling field,and could control barnyard grass.
