What should be paid attention to when mixing pesticides?

It should be noted that it is not recommended to use chemical drugs to kill insects and bacteria. Generally speaking, pesticides can be mixed with acidic ones, and those containing biological bacteria cannot be mixed with fungicides and pesticides. Do not mix nitrogen-containing pesticides with biological agents.

It is advisable to play separately. Improper mixing and dilution of pesticides affects the efficacy of the product. If the dilution is not sufficient, there is a risk that the sprayer will clog the nozzle.

A variety of products are mixed and high concentration of nutrients is proportioned, for example, there are more potassium dihydrogen phosphate commonly used in the market, and the high temperature concentration is too high, which will cause the phenomenon of "burning seedlings". According to the selection of crops, control the dosage, as far as possible to use a single nutrient, amino acids, humic acid to compare neutralization, similar to the content of nutrients plus hormone regulation according to the growth stage and pathological needs of crops.

According to the nature of fertilizers and pesticides, it is pH, and the combination can be mixed, depending on the climate, temperature and humidity dilution concentration. Pay attention to the "drug damage", after the drug damage, there will be drug damage fruit, and there are large black spots and burnt lumps on the fruit! An effective way to avoid this is:

Do not spray pesticides at high temperatures! It is recommended to do it before 10 am and after 4 pm! Moreover, it is also extremely bad for the human body, and can cause dizziness and poisoning in serious cases.

To clarify the effect you want to achieve and whether the target can withstand it, this needs to be analyzed on a case-by-case basis.

Under normal circumstances, the mixing order is micro fertilizer - wettable powder - suspension agent - water agent - emulsifiable concentrate, each time the mixing is carried out in pairs, and then add the third after the two are completely integrated, it is recommended that the total number of mixtures should not exceed three, otherwise the stability of the pesticide will be destroyed. When there is oil slick, large precipitation, bubbles and abnormal color, it is recommended to stop mixing and find out if the chemical structure of the pesticide has been damaged. If you can't judge yourself, then it is prudent to give up using it.

General microbial sterilization, insecticides and herbicides should not be mixed with chemical fungicides that can kill microorganisms, otherwise they will not only fail to achieve the effect, but also destroy the efficacy. When you mix two or three pesticides, the effect is good, it is recommended not to use the same pesticide for a long time to mix, one crop will be resistant, and the mixture of other ingredients can also reduce the residual components of the same pesticide, helping you to meet the pesticide residue threshold limit.

It is necessary to grasp the ratio of pesticides, to grasp the concentration of pesticides, to observe the state of pesticides, and not to choose the medicinal properties.

Pay attention to the chemical reactions generated, but also pay attention to the mixing techniques, but also pay attention to the hazards, pay attention to the efficacy, pay attention to the specific effects.

When mixing pesticides, it should be noted whether the two pesticides will have a chemical reaction that can cause toxicity to the plant.

Alkaline pesticides should not be mixed with alkaline pesticides. Most common pesticides are low-acid. Only a few pesticides are alkaline.

Alkaline pesticides include a mixture of inorganic copper, copper sulfate, and stone sulfur. These pesticides cannot be mixed with other pesticides because alkaline and acidic drugs react. A neutralization reaction can occur, making the pesticide ineffective or even ineffective.

At the same time, it is not used with weakly alkaline pesticides and also undergoes chemical reactions. Please read the instructions carefully when using pesticides. What cannot be mixed should be used separately and <>

Alkaline pesticides are acidic when the pH is below 7 and alkaline when the pH is above 7. In pesticide mixtures, chemical changes often occur that lead to reduced effectiveness or failure. Therefore, attention should be paid to the reasonable ratio of acid-base agents.

Generally, pesticides are acidic pesticides. When alkaline pesticides are mixed with other pesticides, alkaline neutralization and acid neutralization reduce the effectiveness of other pesticides, so that no other pesticide effects are produced. It is important to note that acidic pesticides cannot be mixed with alkaline pesticides.

In general, most pesticides are:

Weakly acidic, only some pesticides are alkaline. Alkaline pesticides include mixtures of inorganic copper hydroxide (which can be killed), copper sulfate, sulfurite, etc. In general, these pesticides cannot be mixed with other pesticides.

I don't know if the insecticide is alkaline or acidic, I forgot the name of my peanut bug.
