How to compound pesticides to achieve a good compound effect? Generally speaking, in order to improve work efficiency, pesticide compounding is becoming more and more popular, and various problems will be encountered in the compounding process, some of which are caused by the compounding sequence.
First, the pesticide mixing sequence should be accurate. The mixing order of pesticides should be accurate. The mixing sequence of foliar fertilizer and pesticide is usually as follows: add foliar fertilizer, wettable powder, suspension agent, water agent, and emulsifiable concentrate in turn, and then add the next one after each is fully stirred and mixed.
2. Add water before dosing and dilut twice. Add water first and then add medicine, when diluting for the second time, pesticide manufacturers recommend adding more than half a bucket of water to the sprayer first, and then stirring evenly after adding the first pesticide. Then, dilute the remaining pesticide in a plastic bottle, pour it into a sprayer, mix well, and so on.
Thirdly, spray immediately after dispensing. Spray immediately after dispensing. Most of the time, vegetable farmers usually prepare the medicine at home and transport it to the shed to spray.
Most of the time, the medicine is ready for a few hours. Although the liquid medicine has no reaction at the beginning of the configuration, it does not mean that it can be stored for a long time at will, otherwise it is easy to react slowly and gradually reduce the efficacy.
Here is the order in which pesticides are mixed. Regardless of the season, the safe use of pesticides is paramount. When using pesticides, try to configure them under the guidance of plant protection technicians or by reading the instructions.
In order to delay drug resistance, treat insects and weeds at the same time, and improve the control effect of pesticides, according to the principle of one drug and multiple treatments, the pesticides prepared by the compound preparation method according to a certain pesticide ratio are called compound pesticides.
Compound pesticides were developed in response to pest resistance and difficulties in the development of new varieties of pesticides. Recent advances in pesticide research show that the combined use of pesticides is an effective measure to overcome and delay pest resistance and prolong the service life of old pesticide varieties. Many farmers hope to achieve the effect of treating two diseases at the same time by mixing two or more drugs at one time; Some people want to improve the effectiveness and quick-acting effect of chemical control by blending.
-
First of all, when we prepare pesticides, we must mix them in a certain proportion, not too thick, not too light, first of all, we must pay attention to the order, and then we must pay attention to the second dilution, and we must use it immediately after the pesticide is prepared.
-
At this time, it is necessary to use some ingredients that are relatively safe, and at the same time, after mixing, it can not produce a particularly strong chemical reaction, and then we must pay attention to the ratio of each pesticide, and we must pay attention to the appropriate time, and we must avoid rainy days or when the temperature is particularly high.
-
It is to compound according to their own pesticide needs, and when they are used in combination, they can not pollute the environment or affect crops, and they must also have a very good effect on related agriculture.
-
It can be matched and blended according to the proportion, so that the pesticide effect will be very good, and it will also be very helpful to crops.
-
This needs to be determined according to the actual situation, different land, different climate, different weather, different plants, and the ratio method used is completely different.

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.
-
If you want a good effect, you can choose to use fungicides and insecticides together. Once there are worms in some wounds, then it is inevitable that there will be bacteria, especially some mites, these worms will gnaw on these pus crops, resulting in some viruses breeding bacteria breeding, we kill insecticides at the same time, if there is no effective addition of some fungicides, then there will be a bad consequence. To give a simple example, we are killing insects, but later it will cause some bacterial diseases, which will also affect crops, so in order to avoid the occurrence of bacterial diseases after insecticide, it must be mixed with fungicides.
Mixed pesticides can not be retained for too long, and a principle of ready-to-use must be selected. Because once the pesticide is selected for dispensing, it will be easy to produce some reactions, if the configuration time is too long or the configuration is placed in the watering can for too long, it is easy to stratify, so it should be used up within an hour after the preparation, so that it can better have this effect. <>
The mixing of pesticides must be added with water first, and then diluted. Nowadays, many pesticides are concentrated in high concentrations and need to be blended with water, generally speaking, some are pressed by 1:11:
The ratio of 100 is diluted, so when the pesticide is prepared, it should also be like this, after the two pesticides are ready, they can be mixed together and stirred evenly. If you mix well and then use it, the effect will often be better, but if you don't mix it well, it is likely that the effect is not very satisfactory. <>
For the mixed use of pesticides, it is necessary to grasp the order when configuring. Generally speaking, we can ask the shopkeeper if we don't understand the place where we buy pesticides, usually they will tell us how to use this pesticide, which fertilizer to add first, then which fertilizer to add, and finally which kind of agent to add, and master the corresponding order to ensure this effect.
-
You can use a 1:1 way to match, so the matching effect is the best, and the help for crops is also the best.
-
This should be determined according to the actual situation, most of the effects are very good, can be carried out very well, effective prevention of pests and germs.
-
It is necessary to pay attention to the efficacy of pesticides, and when mixing them, we must pay attention to the appropriate ratio, and do not make the efficacy volatilized, nor can there be particularly serious pesticides, and we must pay attention to the time of use.
-
Bordeaux liquid and stone sulfur mixture should be chosen, the combination of these two pesticides is more effective, and it will not harm the human body.
-
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.
-
We go to the agricultural material store to buy goods, either to buy insecticide, or to buy sterilization, and in the prevention and control of pests and diseases, a single dose has begun to gradually fade out of everyone's field of visionIn order to maximize the effect of pesticides, increase efficiency with a small amount, and reduce labor costs, people usually choose a variety of pesticides for mixing. Pesticide mixing can not only increase the control effect, but also reduce resistance, and most importantly, it can broaden the effect of control, which can not only cure diseases but also give nutrients to crops, and the effect is better.
Pesticide mixing is required, first of all, it must be accurate in sequencing, add water first and then add medicine, no matter what agent is mixed, it must be paid attention to, and it can not be used for a long timeIf pesticides with different poisoning mechanisms are mixed, although the control effect can be improved, we must also ensure that they can complement each other, rather than restrain each other.
If pesticides are mixed with synergists, although there is no clogging effect on pests and diseases, after mixing with pesticides, it can improve the effect of control, in shortIt must be mixed rationally, if the mixing is not reasonable, the effect of the drug is not heavy, it is likely to produce vital problems.
The following points must be paid attention to when mixing pesticidesFirst of all, it is not possible to change the physical properties。In addition, granules, fumigants, aerosols, etc. can be mixed, but between different models, such as emulsifiable concentrate, brine water solvent, etc., this liquid agent with water as the medium can not be used arbitrarily.
Secondly, it cannot cause chemical changesIn addition to paying attention to the acidity and alkalinity of the drug after taking it, it is also necessary to ensure that they cannot lose their activity, otherwise after some chemical changes, it is likely to cause great harm. Finally, biological pesticides should not be mixed with fungicides, and pesticides with cross-resistance should not be mixed.

The compound and mixing of pesticides refers to mixing two or more pesticides together to make a preparation or mixing them before use. At present, the compound and mixed pesticides are developing rapidly, and there are many varieties, showing certain superiority and vitality. So what should be paid attention to when compounding and mixing pesticides?
The chemical structure and chemical properties of the active ingredients of pesticides are the basis of their biological activity, so special attention should be paid to whether the active ingredients and emulsifying properties of the mixed pesticides are changed when using pesticides, because this directly affects the efficacy of the drug. Therefore, the mixing of pesticides is not a simple mixture, but through the scientific way of chemical structure and properties, through verification to ensure the safety of humans, animals and the environment, to prevent or delay the emergence of pests resistance.
The physical properties of pesticides mixed in the field should remain the same. If there is stratification, flocculation and precipitation after mixing, or the suspension rate is reduced or even crystallization is precipitated, this cannot be mixed. After compounding and mixing, the toxicity to humans, animals, poultry and fish and the harm to natural enemies and other beneficial organisms should be reduced.
Some pesticides are mixed to increase their efficacy, but their toxicity also increases, such as; Malathion is safe for humans and animals, and is easily decomposed by biological enzymes in humans and animals. However, when mixed with dichlorvos and trichlorfon, dichlorvos and trichlorfon inhibit the activity of this enzyme and produce high toxicity. Therefore, this situation cannot be mixed.
Pesticide mixing sequence. The order of mixing foliar fertilizer and pesticides is usually as follows: foliar fertilizer, wettable powder, suspending agent, water agent, and emulsifiable concentrate.
After compounding and mixing, it should have different modes of action and control targets, so as to achieve the effect of expanding the insecticidal spectrum. For example, insecticides and fungicides are mixed to prevent diseases and treat insects, and insecticides and ovicides are mixed to treat insects and eggs. The amount of pesticide residues in agricultural and sideline products after compound mixing should be lower than that of pesticides alone.
After compounding and mixing, farmers should be able to reduce the cost of use. In short, as long as the above points are guaranteed, the pesticide compound can achieve better results.
These pesticides should be sprayed on the leaves of the rice field, or these pesticides should be poured directly on the roots of the rice field, or some solid pesticides can be used, and then slowly released. When applying pesticides to rice fields, do not spray them in areas with many fish, so as not to let the fish eat them by mistake.
