笔者在田间调查和市场调研中获悉,今年全国各地应用玉米茎叶除草基本属于正常情况,而东北三省却多点出现应用烟嘧磺隆系列、硝磺草酮系列除草剂后,玉米生长缓慢,严重受到抑制、叶片失绿呈白化或黄化、新叶扭曲或卷缩、茎秆发脆易折断、次生根不伸长下扎等药害症状,有的还造成不良事件。一直处于全国化学除草领先地位的东北区域,为何产生上述情况,值得思考。
The author learned in the field investigation and market research that this year the application of corn stem and leaf weeding in the country basically belongs to the normal situation. However, the application of nicosulfuron series and mesotrione series herbicides in the three northeast provinces appeared more slowly, Seriously inhibited, the leaves lost green albino or yellow, new leaves twisted or curled, brittle and easy to break the stems, secondary roots do not extend under the bars and other phytotoxicity symptoms, and some also cause adverse events. Has been in the northeastern region of the leading chemical weed control in the country, why the above situation is worth thinking.
