47%异隆·丙·氯吡可湿性粉剂与常用茎叶处理药剂混用对晚播麦田杂草防效及小麦的安全性

Weed Control Efficiency and Wheat Safety of Isoproturon Pretilachlor·Halosulfuron-Methyl 47% WP Applied with Common Foliage Herbicide Treatments in the Late-Seeded Wheat

2018年在江苏省扬州市晚播麦田示范验证47%异隆·丙·氯吡可湿性粉剂与小麦田常用茎叶处理剂混用对杂草的防除效果及对小麦的安全性。结果表明,小麦播后7 d 47%异隆·丙·氯吡可湿性粉剂3 000 g/hm^2封闭处理、小麦3叶1心时47%异隆·丙·氯吡可湿性粉剂3 000 g/hm^2与3%甲基二磺隆油悬浮剂450 mL/hm^2桶混用对晚播稻茬麦田中的菵草、日本看麦娘、看麦娘、牛繁缕、荠菜、野老鹳草的株防效和鲜质量防效均高于90%,对小麦安全。

A late-seeding wheat field experiment was conducted in Yangzhou to determine the efficiency and selectivity to wheat of a formulated mixture containing isoproturon o pretilachlorohalosulfuron-methyl(47% WP)mixed with common foliage herbicide treatments in 2018.The herbicide mixture applied in pre-emergence at 3000g/hm^2 alone or mixed with mesosulfuron-methyl 3% OF at 4500mL/hm^2 effectively controlled Beckmannia syzigachne,Alopecurus japonicus,Alopecurus aequalis Sobo.,Malachium aquaticum(L.)Fries,Capsella bursa-pastoris and Geranium carolinianum L.at levels above 90% in the late rice stubble wheat field,being also safe to wheat.
