Small agricultural pesticides such as mist sprayers and sprayers should be cleaned immediately after spraying, especially after using highly toxic pesticides and various herbicides, they should be immediately cleaned in the drug barrels, otherwise crops or vegetables It will produce poison. For example, the day before the use of "long-effect Ling" pesticide spray cotton, and the day after the day in the case of not cleaning the same medical equipment, but also use the "quick kill Ding" spray vegetables, so that the poisonous pesticide residue in the barrel of the drug sprayed to the vegetables On the herbicides have long-lasting leaf plants, there are broad-leaved plants, if not clean the use of drugs in the course of use, when used alternately, it is easy to hurt different types of plants. Therefore, the sprayer, mister, etc. must not be washed after use. Specific cleaning methods: 1. Pesticides (1) After the general pesticides are used, wash them repeatedly with clean water and dry them upside down. (2) For the highly toxic pesticides, after the use of mud or water can be repeatedly washed, dry upside down. 2. Herbicides (1) Water cleaning: Herbicides commonly used in wheat fields such as superstars (tribenuron), herbicides in the corn field such as ethylene mixture, soybeans, herbicides in the peanut field, such as herbicides, and herbicides in rice fields. After the hit, Bendason, etc., need to immediately clean the barrel and parts with water several times, and then fill the sprayer with fresh water for 2 to 24 hours, and then clean it 2-3 times, then you can use it with confidence. (2) Slurry cleaning: For the king of the track (commonly known as a sweep of light) can be passivated in case of soil, lose the principle of herbicide activity, so after the herbicide without trace, just as soon as the sprayer with muddy water several times to clean Wash it with water again. (3) Scrubbing with ferrous sulfate: Among the herbicides, only the 2,4-D ester is the most difficult to clean. After spraying the herbicide, 0.5% ferrous sulfate solution should be used to fully wash, and then the cotton, peanut and other broad-leaved crops should be tested for safety before re-applying other herbicides.
