How to clean a sprayer that has been sprayed with pesticides

First of all, the sprayer that has been sprayed with herbicide (glyphosate) can be cleaned with muddy mud water, and then the mud can be washed off with clear water, and then it can be used. However, we also need to know that the types of herbicides are different. Different cleaning methods are used. There are generally three types of herbicides currently on the market: water, suspension, and emulsion. Therefore, it is necessary to decide how to clean the most correct according to the type you use, but the principles are actually the same. , Is to use clean water or add some cleaning agent, shake up and down to wash away the pesticide residues in the sprayer.

Of course, most pesticides are acidic. We can use the principle of acid-base neutralization and put some alkaline things, which can also have a very good effect. For example, put some edible alkali, which is what we often say Baking soda. However, if a special herbicide is used, it is recommended to wash it with detergent: in fact, washing with water can achieve the effect of removing residues, but for herbicides such as paraquat (currently banned) or glyphosate, we It can also be washed with detergent, and when configuring the glyphosate solution, soft water or very clean water must be used to ensure the herbicide effect. Therefore, sprayers that have used glyphosate can clean residual glyphosate with turbid muddy water.

However, we must also know that all herbicides have to reach a certain concentration to produce their medicinal effects. It does not contain a small amount of ingredients that will cause phytotoxicity. However, it must be cleaned after use; if it is the kind of sprayer , The method is similar to the above. The medicine bucket above is larger. You can pump in clean water with a hose, and then use a mop or other things that can be inserted into it to clean it and wash it several times. In addition, there is a more troublesome method. , That is, disassemble all the parts of the sprayer, place it in the sprayer where the herbicide is installed, plug all the holes in the sprayer, and then add about 50 degrees of alkaline water, wash them one by one, and then rinse with clean water. Although troublesome, the cleaning effect is very good.

There is a principle to keep in mind when cleaning the sprayer, which is to use alkaline substances such as herbicides to clean, such as laundry, baking soda, ash, etc., while insecticides are generally cleaned with acidic substances; Finally, I want to remind everyone that it is better to pour the water from the sprayer into the sewer, not into the vegetable field or the field, so as to avoid soil pollution.
