Sprayer cleaning method

A sprayer is an indispensable agricultural tool for agricultural production. It is used very frequently. Improper cleaning will reduce the efficacy of subsequent use of pesticides, and even cause phytotoxicity.

The cleaning method of the sprayer is: for insecticides and fungicides, it is generally washed repeatedly with clean water, and dried upside down. For more toxic pesticides, it can be washed repeatedly with muddy water after spraying, and dried upside down.

For herbicides, it is generally necessary to immediately wash the copper and various parts with water several times, and then fill the bucket with water and soak it for 2-24 hours. After 2-3 washes, you can use it with confidence. After using Kewuxian and glyphosate, according to the principle that these herbicides will inactivate and lose their herbicidal activity in contact with soil, it is only necessary to immediately wash the sprayer with muddy water several times, and then rinse with water.

If 24-D butyl ester is used, it should be washed thoroughly with a 0.5% ferrous sulfate solution.

Cleaning the sprayer is a must. This not only ensures the normal use of the sprayer, but also ensures the performance of the subsequent pesticides, and will not cause pesticide damage due to pesticide residues.
