First of all, after washing with a sprayer of herbicide (glyphosate), it can be washed once with turbid muddy water, then washed off with mud, and it can be used. However, we also need to know the different types of herbicides. Different cleaning methods are used. There are generally three types of herbicides currently on the market: liquids, suspensions, and emulsions. Therefore, depending on the type you use, it is most correct to decide how to clean, but the principle is almost the same. It is to clean the pesticide residue in the sprayer by shaking it with water or adding a cleaning agent.

Of course, most of the pesticides are acidic. We can use the principle of acid-base neutralization and put some alkaline things. This can also be very effective, such as putting 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, the water can be cleaned to achieve the residual effect, but for paraquat (currently banned) or glyphosate, these herbicides are strong. It can also be washed with washing powder, and when the glyphosate solution is configured, soft water or very clean water must be used to ensure the herbicidal effect. Therefore, a sprayer using glyphosate can wash residual glyphosate with turbid muddy water.

However, we also need to know that all herbicides must reach a certain concentration to produce a drug effect. It does not contain a little ingredient and it will cause phytotoxicity. However, it should be cleaned after use; if it is a drug-using vehicle The method is similar to the above. The upper barrel is larger. You can use a water pipe to pump in water, then use a mop or other things that can be inserted into it to clean it. Wash it several times. In addition, there is a more troublesome method. Is to disassemble all parts of the sprayer, place it in the place where the sprayer is filled with herbicide, plug the hole in the bend of the sprayer, then add about 50 degrees of alkaline water, wash it one by one, then wash it with water. Although it is troublesome, the cleaning effect is very good.

In short, there is a principle to be remembered when cleaning sprayers, that is, herbicides should be washed with alkaline substances, such as washing clothes, baking soda, ash, etc., while insecticides are usually cleaned with acidic substances. Oh, the last thing to remind everyone is that the water from the sprayer should be poured into the sewer. Do not pour it into the vegetable field or the field to avoid soil pollution. However, from the professional point of view of our service team, it is best to spray the pesticide sprayer separately with the sprayer that sprays the herbicide. This saves a lot of trouble and reduces unnecessary losses caused by the chaos.
