目前生产上的除草剂使用量很大,但由于使用不当经常产生药害。因此,使用除草剂应注意以下几点:1.避免雾滴飘移.有些农药喷洒时雾滴飘移,造成相邻作物的药害发生。如在麦田使用2,4—D丁酯防除阔叶杂草,若邻近有双子叶作物,则易发生药害。2.控制药液挥发.使用高挥发性除草剂喷雾时,药液挥发造成附近的敏感作物受害。如稻田使用禾大壮或禾大壮与西草净、二甲四氯混合
The current production of herbicides used in large quantities, but due to improper use often produce phytotoxicity. Therefore, the use of herbicides should pay attention to the following points: 1. Avoid drifting droplets.Some pesticides when spraying droplets drifting, causing injury to neighboring crops. Such as the use of 2,4-D butyl wheat in the field of broad-leaved weeds control, if there is a dicotyledon adjacent crops, it is prone to injury. 2. Control of volatile chemicals When using highly volatile herbicide spray, volatile chemicals cause nearby sensitive crop victims. Such as paddy fields Wo large Zhuang or Wo strong and West grass net, MDTC mixed
