How much do you know about pesticide compounding?

The effective mixing of pesticides can improve the control effect, slow down the pests and pests to cause resistance, improve the control effect, reduce the dosage, prevent the mixing of pesticides for different pests, and reduce the frequency of pesticide application, thereby reducing labor costs.

FarmingThe order in which the drugs are mixed

The order of pesticide mixing should be accurate, and 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 successively (under normal circumstances, pesticide mixing does not have to exceed three kinds), each addition is sufficient to mix and mix, and then add the next one.

When mixing the secondary diluent, it is proposed to add 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 the dilution into a watering can, mix well, and so on (if you want the medicine to be effective, you can't be lazy).

No matter which drugs are mixed, you should pay attention to "ready to use, not suitable for long-term storage". Although the liquid medicine is not reflected when it is first dispensed, it does not mean that it can be stored for a long time, otherwise it is easy to cause a slow reaction and gradually reduce the efficacy of the medicine.

differentChlorpyrifosis system of pesticide mixing

The mixed use of pesticides with different systems of action can improve the control effect and slow down the pest resistance.

differentToxic effects of pesticides mixed

Insecticides have contact killing, stomach poisoning, fumigation, systemic and other methods of action, fungicides have maintenance, treatment, systemic and other methods of action, if this has different preventive effects of the agent mixed, can fill each other, will cause a good control effect.

Acting ondifferentInsect pesticides are mixed

The mixed use of insecticides acting on different insect states can eliminate all kinds of insect pests in the field, completely eliminate insects, and then improve the control effect.

Mixed use of pesticides with different timeliness

Some types of pesticides have good fast-acting control effects, but the effective period is short; Some have poor fast-acting control effects, but they have a long time of action. The mixed use of pesticides not only has a good effect on the back line of application, but also has a long-term preventive effect.

Mix with synergists

Although the synergist has no immediate poisoning effect on pests, it can improve the control effect when mixed with pesticides.

Acting ondifferentDisease of pesticide mixing

When several types of diseases occur at the same time, this method can reduce the frequency of spraying, reduce the working time, and then improve the effect.

Common problems with pesticide mixing

There are many benefits to mixing pesticides, but don't mix them around. Unscientific mixing is not only unprofitable, but also produces relative practical effects. The following aspects should be paid attention to in the mixed use of pesticides.

Physics properties are not changed

That is, after mixing, there can be no oil bleaching, flocculation, deposition or color fading, nor can it be hot or cause bubbles. If it is the same granule, or the same tablet, smoke, and fog, it can generally be mixed.

In the middle of different preparations, such as wettable powder, emulsifiable concentrate, concentrated solvent, suspension, water organic solvent and other liquids with water as the substance, they are not suitable for random mixing.

Be sure to mix in order, pay attention to the composition of pesticides, but also for secondary dilution, must be ready for use, to avoid volatilization, but also away from water sources.

Pesticides are indispensable in the process of agricultural production. Appropriate pesticides should be selected for different pests and diseases. Pesticide compounding should also be based on the principle of safety.

I didn't know much about pesticides, but I only knew about the types of pesticides and the use of pesticides.

I don't know much about pesticide compounding, and every time the pesticide shop owner helps me with it.

Pesticide compounding generally refers to in order to improve the efficacy of pesticides and strengthen the prevention and control of pests and diseases, pesticide compounding is now becoming more and more popular in pesticides, which can alleviate a lot of trouble for farmers. <>

First, how to use pesticide compounding.

In order to improve the control efficiency and reduce the degree of labor, this requires a variety of pesticides to be mixed or compounded together to achieve better efficacy. This is especially true when a disease or pest becomes resistant to a pesticide.

It is also necessary to mix the more sensitive agents of the target organism. The mixing of pesticides is the most common method of use in production, and it is often not so simple to mix several pesticides together only by their own control intentions. The properties of pesticide compounds, preparation technology, and the changing trend of field diseases and pests are all important factors restricting the mixing formula of pesticides.

The purpose of pesticide mixing is to control pests and diseases in the field, so the following indicators should be achieved after mixing different pesticides<>

Second, the vegetables that have been sprayed with pesticides can be eaten for a few days.

Now farmers grow crops, whether it is weeding or treating crops are inseparable from pesticides, some vegetables and insect pests are very many, without pesticides at all. So we must clean the vegetables we buy outside when we eat them, if the pesticide residues are too serious, it will definitely have some impact on the human body, everyone from the vegetable market.

If the vegetables you buy can be preserved, leave them for two or three days as much as possible before eating, or you can add a little less edible alkali when washing the vegetables.

This allows the pesticides to decompose faster (many pesticides are acidic) and then wash them clean! In addition, you can soak it in water for about ten minutes to dilute the pesticide residue concentration on the surface of the greens, and then change a basin of water to wash the greens many times. To remove pesticide residues in vegetables, rice water can also be used.

The rice washing water is acidic, soak the vegetables in the rice washing water for about 10 minutes, and wash it with water. <>

Generally, in order to improve work efficiency, pesticide compounding is becoming more and more popular, and various problems will be encountered in the compounding process, and some problems are caused by the compounding sequence. Pesticide mixing order, pesticide mixing order should be accurate. The order of pesticide mixing should be accurate, and the order of mixing foliar fertilizer and pesticides is usually:

Foliar fertilizer, wettable powder, suspending agent, water agent, and emulsifiable concentrate are added in turn, and each one is fully stirred and mixed, and then the next one is added.

This means that this pesticide is a mixture of multiple pesticides. This pesticide has many benefits and can improve work efficiency.

It refers to the high efficiency, the mixing order is more rigorous, and there are many precautions for this type of pesticide, which there are many types of pesticides.

At this time, it is necessary to choose the right pesticide according to the crop, and at the same time, we should also pay attention to the ratio of pesticides.

It should be matched according to the proportion of pesticides, and it should be matched according to the regulations of pesticides, so that the pesticides that are matched will not be harmful.

First of all, we must prescribe the right medicine, choose the right pesticide, but also should pay attention to the proportion of pesticides, but also need to pay attention to the dosage of pesticides, do not spray too much, otherwise it will be twice the result with half the effort, Liang Jie should also do a good job of personal protection of stupid lead, to avoid pesticide contact with **.

The most scientific way is to blend according to the instructions of the pesticides, so that the most ideal concentration can be achieved.

Pesticide compounding is often heard, what is pesticide compounding? Pesticides with two or more different insecticidal principles (diseases) are mixed and processed in a certain proportion to produce a new pesticide variety, which is called an insecticide compound. This compound insecticide has no chemical changes to prevent drug damage.

Many pesticides cannot be mixed with alkaline pesticides or acids. For example, under alkaline conditions, such as Bordeaux liquid and stone sulfur mixtures, carbamate and pyrethroid pesticide mixtures, it refers to mixed (compound) pesticide formulations, that is, when pesticides containing two or more active pesticide ingredients, they can be selected with strong permeability.

Agents and dosage forms with good adhesion. However, azoxystrobin cannot be compounded with silicone, which is very permeable, and so is silicone, which is a pesticide formulation. After mixing the CADA ingredients in proportion, the plant converts the pesticide mixture into a given dosage form so that the third and second dilutions directly improve efficiency.

There are complementarities and synergies between pesticides. For example, when playing with insect medicine, add some synergist, dilute it as an ingredient, and dissolve it completely so that it can be used; carbendazim is composed of carbendazim and jinggangmycin; The polyfluorinated mixture consists of carbendazim and tiram.

The order in which fungicides and pesticides are mixed should be precise. The mixing order of foliar fertilizers and pesticides is usually as follows: micro fertilizers, water-soluble fertilizers, wet powders, water-dispersible granules, suspensions, microemulsions, water emulsions, emulsified oils are added by Sua Vez (in principle, pesticides are mixed and processed in a certain proportion to produce a new pesticide variety, called a pesticide composition.

Pesticide composition standards: 1There must be no chemical or physical changes to the various active ingredients in the mixture.

The various active ingredients in the mixture can also be used alone to kill and synthesize drugs.

First of all, we should pay attention to whether the physical properties have changed, as we all know, several pesticide preparations have certain requirements in physical properties, such as the financial and dispersion of dust particles, emulsifying properties and emulsifying properties, etc., in the spraying process can save manpower and material resources, to achieve the purpose of two or more diseases. Many farmers and friends will mix pesticides to spray.

For many growers, pests and diseases are the biggest headache for their crops, butAccording to the current situation, it is difficult to use a single agent to play the role of insecticide and sterilization, so compound pesticides are very importantThere are many requirements for the addition order of different dosage forms in pesticide compoundingThe correct addition sequence is conducive to the dissolution of pesticides, and can maximize the effect of pesticides, if the addition sequence is incorrect, the efficacy is reduced, not to mention, it may even cause great harm to crops. SoWhen compounding pesticides, it is necessary to add water first and then add medicine, carry out secondary dilution and mixing, and secondly, you can also choose to mix with synergistsIn this way, it can also improve the control effect of pesticidesAll in all, as long as the physical and chemical properties of the pesticide are not changed, the pesticide compound is good.

Many people's method of compounding pesticides is very common, the most common three addition sequences are to pour any pesticide into the medicine barrel at one time, add water and stir evenly, the second is to compound in accordance with the dosage form order for secondary dilution, and the third is to add the medicine barrel in accordance with a certain addition order and in the normal order.

But we must understandAlthough the mixing of agricultural products is a way that is often used, different pesticides and fertilizers have their own effects, and not all pesticides can be mixed, once the mix is wrong, there is a good chance that it willIt causes the problem of burning roots and seedlings, and produces fertilizer damage and vital problems.

We have to understandThe mixed use of agricultural drugs should not be too many, generally not more than threeOtherwise, it is very likely that they will have a mutual restraint between them, and the possibility of interaction will be greatly increased, which may eventually make the drug ineffective and the risk will increase.

Finally,When mixing pesticides, it is forbidden to use well water or sewageOtherwise, it may cause a chemical reaction with the pharmaceutical industry, produce sediment, reduce his requirements, and secondly, there are many impurities rich in sewage, which may clog the sprinkler, in short,The order in which pesticides are mixed is very important, and there are also principles that must be followed, and they cannot be used indiscriminately.

Pesticides play a vital role in our agricultural production activities as chemical agents used in agriculture to control pests and diseases and regulate plants. However, sometimes, because different pesticides have different effects and are not very complete, we often carry out pesticide compounding in order to delay drug resistance and treat pests and weeds.

As the name suggests, pesticide compound refers to the use of compound configuration method to configure pesticides with better control effects according to the principle of one drug and multiple treatments, according to a certain mixing ratio of pesticides. The compound use of pesticides can better overcome and delay the resistance of pests, and has played an unexpected good application effect. However, for pesticide compounding, we must also master certain principles, and we will explain the principles of pesticide compounding below.

First of all, the pesticide compound cannot change the physical properties of the compound pesticide, that is, there can be no flocculation, precipitation or discoloration after mixing, and at the same time, it can not produce bubbles and heat. Generally speaking, pesticides of the same type can be mixed, but different dosage forms cannot be arbitrarily mixed.

Second, it can not cause chemical changes, because many agricultural pesticides, its acidity and alkalinity have obvious differences, so its composition should be analyzed when compounding, understand its chemical properties, and compound through appropriate methods; Finally, biopesticides should not be mixed with fungicides. On the premise of ensuring that pesticides play their original roles, we should fully consider the complementary effects, and only complement each other can we treat a variety of diseases, insects and weeds that occur at the same time. In short, the principle of pesticide compounding, we must configure it according to the rules.

Although the effect of compound pesticides is more comprehensive, the effect is more complete, and can have a great impact on our agricultural production, but in the process of compounding, we must pay attention to the above principles in order to configure the compound pesticides we need.
