唑草酮、双氟磺草胺、2甲4氯、啶磺草胺、氟唑磺隆等药对荠菜均有良好防效,生产上可以因地制宜选用。将唑草酮与双氟磺草胺混用,能有效防除麦田的荠菜等阔叶杂草。很多地方的荠菜对苯磺隆、苄嘧磺隆、氯氟吡氧乙酸产生了较高的抗耐性,导致防效下降,这些地方荠菜发生严重的田块不宜用这些药除草。唑草酮是美国富美实公司开发的茎叶处理除草剂,对小麦田绝大多数阔叶杂草均有良好的杀灭效果,对荠菜有突出防效,杀草速度快,一般施药后2~3天敏感杂草就表现药害症状,一周后枯死。唑草酮在麦苗3叶期以后、田间阔叶杂草出齐后使用,用
Oxaprozin, florasulam, 2 A 4 chlorine, pyridine sulfamethoxazole, flurazasulfuron and other drugs on Shepherd’s-purse have a good control effect, the production can be selected according to local conditions. The combination of oxacillin and florasulam, can effectively control broadleaf weeds such as shepherd’s purse in the field of wheat. Many places of shepherd’s purse on tribenuron-methyl, bensulfuron-methyl, flurbiprofen acetic acid has a higher resistance, leading to decreased control efficiency, these places where shepherd’s purse serious plots should not be weeding with these drugs. Oxaliplatin is a herbicide developed by American Fulimo Co., Ltd., which has good killing effect on the vast majority of broadleaf weeds in the wheat field. It has outstanding control effects on shepherd’s purse, and its herbicide speed is quick. After the general application 2 to 3 days on the performance of sensitive weed poisoning symptoms, died a week later. Forskolin in wheat seedlings after the third leaf stage, field broad-leaved weeds used together, with
