Several problems should be paid attention to when mixing pesticides

In the production of vegetable fields in protected areas, vegetable farmers often mix two or more pesticides in order to save labor and increase the use effect. This kind of compounded pesticide should have some principles and methods in the preparation process, and it should not be chaotic, otherwise it will backfire. 1. After the test, several pesticides are mixed together, and some may cause chemical reactions and generate harmful substances. In addition, the concentration of the mixed liquid is obviously increased, whether it is harmful to the vegetables, whether the concentration of the compound is suitable, etc., these should be tested first and then applied to vegetable production. 2. Use the same dosage form of the agent as much as possible, such as WP or emulsifiable concentrate. 3. If a mixture of pesticides of various dosage forms is required, the medicament should be placed in water in the order of micro-fertilizer → wettable powder → suspending agent → water agent → emulsifiable concentrate, and then the former agent is dissolved and then placed. Into another agent, do not add a few pieces of the drug and then stir. 4, should be used with the use, continue to stir or vibrate during use to prevent precipitation or separation.
