Small plant protection equipment such as mist sprayers and sprayers should be cleaned immediately after spraying, especially after using highly toxic pesticides and various herbicides. Crops produce poison.
After using general pesticides, wash the equipment repeatedly with clean water and dry it upside down. For highly toxic pesticides, they can be washed repeatedly with muddy water after use and inverted to dry.
After using herbicide pesticides, the instrument cleaning methods can be divided into three types: 1. Clean water. Herbicides such as giant stars (trisulfuron-methyl) are commonly used in wheat fields. After they are finished, buckets and parts are washed with clean water several times, then the water is poured into the sprayer and soaked for 2 to 24 hours, and then washed 2 to 3 times. You can use it with confidence. 2. Slurry cleaning. For Grams without trace (commonly known as a sweep of light) can be blunt soil, lost grass-killing activity, after the herbicide can be traced without trace, immediately sprayed with muddy water sprayer several times, and then washed with water. 3. Scrubbing with ferrous sulfate. After spraying 2,4-D butyl ester, 0.5% ferrous sulfate solution should be used to fully wash the equipment.
