How to mix pesticides? How many ideas for pesticide mixing?

When mixing pesticides in production, the following 4 principles must be followed:

Pesticide blending refers to the mixing of pesticides of different types and mechanisms of action to achieve better control effects. When mixing pesticides, the following ideas should generally be followed:

1.No mixing of similar chemicals: In order to avoid chemical reactions and adverse effects, pesticides of the same class should not be mixed. Hold it open.

2.Different types of pesticides are compatible with each other: two or more pesticides of different classes should be selected, and it is best to mix pesticides belonging to different mechanisms of action.

3.Properly control the amount of pesticides: because the mixture will increase the efficacy of the pesticides, reduce the amount of pesticides appropriately to avoid pesticide damage.

4.Pesticide selection according to pesticide use period, crop quality and other factors: different pesticides have different impacts on crops and agricultural environment, and should be reasonably selected according to actual needs.

In general, the quality of pesticide mixing depends on the specific application situation and method, and improper mixing will have a great negative impact on crops and the environment. Therefore, it is recommended that before the use of pesticides, priority should be given to factors such as the effect, use period, and risk degree of a single pesticide, and only in special circumstances can be mixed and used in an appropriate amount.

When adding chemicals for secondary dilution and mixing, it is recommended that for some pesticide varieties, while there are many advantages to a reasonable pesticide mix, it should not be random. Chlorbromoisocyanuric acid does not raise the temperature of organic matter, pests and diseases are increasing, and spraying is becoming more frequent. While some pesticides work well, they should not be used on sensitive crops.

<> there are some common pesticides that can be easily destroyed by medications. If they are mixed with organophosphorus pesticides (malathion, trichlorfon, etc.), they will catch fire. If mixed with an alkaline pesticide, the mixture of the drug is lost.

Proper mixing is not only useless, but also counterproductive. The use of conventional agents and organic copper agents will increase the control effect by more than 50%.

The following points should be paid attention to when mixing pesticides: mixing can achieve good results, but many pesticide varieties are not suitable for mixing due to the nature of pH value or chemical composition. After mixing, it will reduce or neutralize the efficacy of the drug, or cause serious damage to crop medicines, or even stop production!

Add more than half a bucket of water to the spray, mixing and combining can easily cause damage to the drug: wet tujit powder cannot be mixed with parathion emulsion.

mixed use; It shall not be mixed with organophosphorus insecticides, fungicides, and carbamate insecticides, nor shall it be used continuously before and after; Dijundan, Duohe, and Guoding cannot be mixed with emulsion pesticides; Do not mix with mancozeb and the first pesticide, then dilute the remaining pesticide in a plastic bottle, dilute it and pour it into the spray, mix well, and so on (if you want to have good results, the insecticide is mixed in different insect states: the mixed use of insecticides in different insect states may completely kill various pests on the ground, many pesticide fungicides are used in bio** fungicides, such as 10% difenoconazole E, 25% benzbromonitrile, 20% flusilazole prochlorazine and 43% tebuconazole, and some protective agents, such as mancozeb 70%, mancozeb 80%, azoxystrobin 25% and pyrazoxystrobin 25%, which are lethal in order to prevent and at the same time avoid disease. Therefore, microbial insecticides and fungicides cannot be mixed.

Proper mixing of pesticides is important.

The key to mixing is to use two or more types of fertilizers in the same sprayer at the same time. The effective mixing of pesticides can increase the application standard or treat several types of pest control, which can improve the efficacy; Some blends can even improve the drug power and alleviate the adverse reactions of drug resistance, fertilizer damage and other drugs. However, unscientific chemical fertilizer mixing will reduce the potency of chemical fertilizers or cause fertilizer damage.

Therefore, we remind everyone to pay attention to the following aspects to ensure the effective mixing of chemical fertilizers.

The physical properties and structure of fertilizer-related components are the basis of their biological activity. When mixed, it is generally not allowed to cause chemical reactions of related ingredients, which may harm the dissolution of related ingredients. Systemic and parabenic acid fertilizers are more sensitive to alkali, and pyrethroid insecticides and dithiocarbohydrate pesticide fungicides will also dissolve in the case of extremely strong alkali.

Chemical fertilizer mixing is not more than 4 kinds, and the mixed use of chemical fertilizers is generally appropriate for 2-3 types, and 4 can be used when necessary, which will easily cause adverse effects.

When mixing the secondary diluent, first add half a bucket of water to the sprayer and add the first fertilizer to stir. Then, pour another kind of fertilizer into a plastic bottle, add water to the dilution, and then pour the dilution into a sprayer and stir well, and so on.

The order of chemical fertilizer mixing should be precise, first release water and then dosing, and carry out the dilution.

The physical properties of the drug should not change after mixing.

This is also the most important standard for the mixed use of chemical fertilizers, if the mixed use of chemical fertilizers causes sedimentation, fading and other reflections, it should be discontinued. Although most of the species are relatively stable, they are only mixed and used under the standard that the alkali is not too strong.

Mixed fertilizers should be used effectively in the application amount. When two or more pests and diseases appear at the same time, and the mixed single drug is only reasonable for one pest, and the other prevention objectives are ineffective, the solution should contain a reasonable amount of a single agent when applied independently.

When a single dose of a certain type of prevention goal, such as a mixture, is reasonable, the amount of each single dose needs to be reduced accordingly. However, the actual use of each is much more, and it is generally determined according to the results of the study. Generally, it is based on the standard of drug harmony.

If there are 2 single doses in the mixed composition, the amount of use will be reduced by 50% each. If it is a single dose of three, the dosage of each is generally reduced by one-third.

The usual order of mixing a variety of pesticides is: wettable powder, water dispersible granules, suspension agent, water emulsion, emulsifiable concentrate, added in turn, it should be noted that each agent added, stir and mix well and then add the next one. Pesticide mixture should be used at any time, and the liquid medicine prepared on the same day should be used up on the same day.

If pesticides are mixed reasonably, we must pay attention to its order, because the pesticides are used with some chemicals, and if the order is wrong, it will cause very serious damage.

The order of pesticide mixing should be accurate: the order of foliar fertilizer and pesticide mixing is usually: micro fertilizer, water-soluble fertilizer, wettable powder, water-dispersible granule, suspension agent, microemulsion, water emulsion, water, and emulsifiable concentrate are added in turn (in principle, no more than three pesticides are mixed), and each one is fully stirred and mixed, and then the next one is added.

Add water first and then add medicine: When mixing for secondary dilution, it is recommended to add more than half a bucket of water to the sprayer first, and then mix after adding the first pesticide. Then, dilute the remaining pesticides in a plastic bottle, pour them into a sprayer, mix well, and so on (if you want the medicine to work well, don't be lazy).

Whether it is open-field vegetables or greenhouse vegetables, pesticides are indispensable. Nowadays, it is difficult to do insecticide, sterilization using a single dose of pesticides, thereforeOnly a scientific and reasonable mixture of pesticides can play its greatest role. There are many benefits of reasonable mixing of pesticides, which can not only reduce the number of times to take medicine, but also improve the control effect, reduce the dosage, not to mention, but also reduce labor costs, and can play a role in long-term prevention and control, which can be said to be a powerful blow to pests and diseases.

The order of pesticide mixing must be accurate, and in principle, it is best not to mix more than 4 kinds of pesticidesBut in any case, there are many types of pesticides, and the order of baking is usually micro fertilizer, water soluble fertilizer, visible powder, water dispersible granule, suspension agent, micro emulsion, water emulsion, water agent, and emulsifiable concentrate. When adding various pesticides,Each one should be fully stirred evenly, so that each pesticide can be brought into play, and when pesticides are applied to crops, it can play its maximum effect.

Secondly,In the mixing of pesticides, his mixing principle must be kept in mind, first of all, when mixing pesticides with different toxic effects, it can bring good control effects to crops, and if it is mixed with different forms of pesticides, it can also completely eliminate various insect pests in the field, and the control effect can also be improved. If it is mixed with pesticides with different timeliness, its post-drug control effect is good, and the action time is also very long.

When sharing pesticides with crops, we should pay attention to the following aspectsFirst of all, biological pesticides can not be mixed with fungicides, because pesticide fungicides have a strong lethality for biological pesticides, and secondly, the water temperature can not be too low when configuring pesticides, and the water temperature is too low to make pesticides unable to fully dissolve, and the preparation of pesticides with live water is likely to destroy the suspension of the liquid medicine and precipitate, which will affect the medicinal properties of pesticides.

Rational mixing of pesticides is a technical taskEither way, its benefits are recognized by us.

Biopesticides should not be mixed with fungicides, and complementary effects should be considered as much as possible, as some chemical changes may cause pesticide damage. It is required to choose the appropriate timing and agent.

First of all, it is necessary to pay attention to the ingredients, and the two pesticides are mixed together, so that there can be no particularly serious chemical reaction, and then there can be no particularly serious rejection, and the quality of agricultural products must be provided.

When mixing pesticides, try to choose some pesticides that will not conflict, and then be sure to stir evenly, and at the same time should be diluted with water, and at the same time, you should also choose some targeted agents, which is better for crops.
