玉米田化学除草,是实行玉米田免耕,减轻劳动强度,增加经济效益的有效措施之一。通过对大量药剂的筛选,我们发现由都尔加阿特拉津(均由吉林农药厂生产)组成的都阿合剂,是玉米田优良除草剂,其杀草谱广,对禾本科及大部分阔叶杂草均具有较高的除草效果,对玉米生长无影响,每亩成本仅4.41元。使用方法:在玉米播后1周左右,每亩用都尔100克加阿特拉津200克配成药液(用水量不限),均匀喷雾。一般除草效果可达92％左右。
Chemical weeding in corn fields is one of the effective measures to implement no tillage in corn fields, reduce labor intensity and increase economic benefits. Through the screening of a large number of pharmaceuticals, we found that all of Urumqi Atrazine (both produced by Jilin Pesticide Factory), are excellent herbicides in corn field and have a broad spectrum of herbicidal activities against grasses and most Broadleaf weeds have a higher weeding effect, no effect on the growth of corn, the cost per acre is only 4.41 yuan. How to use: About 1 week after sowing in corn, use 100g of aldol and 200g of aldrin per acre to formulate liquid medicine (water consumption is not limited), spray evenly. The general effect of weeding up to 92%.
