First, read the instructions carefully: To understand the pesticides, fungicides, and pH values ​​of various pesticides, see which pesticides are acidic and which pesticides are alkaline. Because a lot of pesticide acid and alkali can not be mixed, after mixing, acid and alkali neutralization, both easy to produce phytotoxicity, but also reduced the efficacy of the two pesticides. To determine which pesticides must be properly matched in order to achieve a certain control effect, it is necessary to make secondary dilutions of various pesticides before they can be mixed together. This is effective and safe, and no phytotoxicity will occur. Only in this way can we have a safe and secure mix.
Second, the mixing of small experiments: first with a small amount of liquid mixing experiments, if there is precipitation, discoloration, strong irritating odor, a lot of foam, avoid must not be mixed, but can not spray to the crop, In order to avoid the occurrence of burning leaves, fruits produce bromine and other undesirable conditions.
Mixed pesticides
In the process of using pesticides, many farmers’ friends do not pay attention to the proper mix of pesticides, and some even have several pesticides with different sterilization and insecticidal mechanisms added together to dilute, so that crops have different degrees of phytotoxicity and cause extreme damage to agricultural production. Big loss. Therefore, only the scientific and rational compounding of pesticides, the use of pesticides with the minimum input, the safest way, can make crops high yield and quality. When pesticides are mixed, they should pay attention to the following aspects:
