What are the five points to pay attention to in the mixing of pesticides?

It is necessary to pay attention to the concentration of pesticides, but also to pay attention to the efficacy, but also to pay attention to the physical reaction of pesticides, the reaction after combining with other drugs, and pay attention to the medicinal properties of pesticides.

It is necessary to pay attention to the proportion, we must pay attention to the configuration of water, in general, there is a sequence, we need to pay attention to the nature of different pesticides, not all pesticides can be mixed, we must pay attention to safety.

First of all, we should pay attention to the proportion and dosage of pesticides, and secondly, we should prescribe the right medicine, and we must avoid chemical reactions when choosing pesticides to mix, and do not mix them casually to avoid toxicity.

The first thing is to choose the right pesticides to mix together, and we must pay attention to the concentration of each pesticide, and we must choose the right ingredients, we must choose the right ratio, and we should also choose to use them intermittently, or you can choose to use them in turns.

Pesticides generally have their own functions, and most pesticides are chemical agents, which are generally not mixed under the guidance of professionals. Mixing may cause pesticides to fail.

<>(1) The mixed use of pesticides must be clarified; The mixed use of pesticides must mainly achieve the objectives of improving efficiency, simultaneous treatment and expanding the control framework; If the above objectives cannot be achieved, no mixing is allowed.

(2) There will be no adverse chemical and physical changes after mixing pesticides, such as the agent will not decompose after mixing, the emulsion will not be damaged, and the suspension will not produce flocculation or a large amount of precipitation. Any drug that easily decomposes under alkaline conditions cannot be mixed with alkaline substances.

(3) After mixing, the mixed solution shall not cause harm to the drug in the culture; In drones, it cannot be mixed with each other, from injuries to drugs.

4) After mixing the product, the efficacy of the mixed liquid should be improved, at least not reduced, that is, the efficiency should be improved after mixing.

Symptomatic and timely medication, according to the types of sunflower diseases, insects and weeds and the occurrence of diseases, insects and weeds, the law of harm, the selection of different varieties of insecticides, different types of pesticides have different control effects on different control objects, before the use of drugs to carefully investigate diseases, plagues and weeds, the best prevention and control period, symptomatic medication, generally choose in the early stage of the occurrence of diseases, insects and weeds, to achieve timely prevention and control.

To ensure the technology and quality of pesticide application, high-quality spraying equipment must be used for pesticide application, and pesticides must be strictly weighed, which is an important part of the prevention and control of diseases, insects and weeds. Pesticides should be measured according to the "Pesticide Instruction Manual", and the dosage should not be increased at will, especially herbicides, so as not to leave residues, pollute the environment and agricultural products, do not use a single pesticide for a long time, scientifically and reasonably deploy pesticides, and delay the development of resistance to pests and weed drugs.

Take care of safe medications. Ensure safe drug collection and scientific drug use to avoid human and animal poisoning. Pay attention to clean the pesticide application equipment and avoid using clean water.

Currently, some of the herbicides used in production are very effective. Because a pesticide remains in the application equipment or the water in which the product solution is prepared, it is easy to cause damage to sensitive crops due to the contamination of a certain pesticide.

To choose the appropriate proportion to proportion, no chemical reaction can occur, pay attention to their own protection of the amount of pesticides should not be too high, the concentration of pesticides should not be too high, when using mixed pesticides, do not cause too much damage to crops, these are the problems that need to be paid attention to.

You should pay attention to the medicinal properties, but also pay attention to the brand, because some medicines may cause great impact and harm if they are mixed together, which may not have any medicinal properties.

Attention should be paid to the varieties of pesticides used, the effects of pesticides, the crops used, the methods used, the number of times used, etc.

The thing to pay attention to is to pay attention to safety, wear protective clothing, and ask in time when you don't understand something, and don't mix pesticides that can't be mixed together to avoid poisoning.

First of all, it is necessary to pay attention to the right time, and must understand the variety of the crop, and then choose the right pesticide, and at the same time must pay attention to the appropriate amount, must do a good job of moisture management, and also must do a good job of ventilation.

When pesticides are mixed, pay attention to the body, be sure to wear masks, wear gloves, use watering cans to spray, do not get too close to pesticides, and then use them in the morning, so that the effect of pesticides can be maximized.

What are the issues to be paid attention to when mixing pesticides? When applying pesticide mixtures, the following problems should be noted:

1. Any pesticide that encounters alkaline substances that are dissolved or ineffective cannot be mixed with alkaline drugs. For example, 1605, dimethoate, insecticide dimethyl parathion insecticides are all neutral or slightly acidic and alkaline pesticides, which are quickly dissolved in the alkaline solution. Therefore, this pesticide cannot be mixed with alkaline pesticides, nor can it be mixed with other alkaline substances such as sodium hydroxide

Lime powder, soap, lysoda, etc. are mixed. Otherwise, it will reduce the medicinal power, or even be ineffective at all, and cause pesticide damage, but although trichlorfon is an acid and alkaline pesticide, because of its unique physical properties, it can be mixed with a certain amount of soap or alkali, and can be quickly converted into an insecticidal double with strong contact killing effect, and at the same time, the medicinal effect period is shortened. Zinc and ammonium in fungicides will also be dissolved ineffectively when encountering strong metaalkali pesticides, so they cannot be mixed with dimethoate oxide and agricultural streptomycin;

2. Pesticides or fertilizers that will undergo chemical changes after mixing and can cause pesticide damage should not be mixed. In inorganic pesticides, pesticides and fertilizers are generally mixed with two or more types of pesticides and fertilizers, which cause pesticide damage to crops because of chemical changes between them.

For example, dimethoate is mixed with agricultural streptomycin and converted into lead polysulfide. It destroys agricultural streptomycin and dimethoate, increases the dissolved amount of copper, and produces a more serious dose. Therefore, these two drugs cannot be mixed, or even can not be used continuously (after spraying the effect of agricultural streptomycin, it must be about 30 days apart before it can be sprayed again);

3. The solvent damage after mixing will not only reduce the medicinal power, but also cause drug damage to the easily used substances, and it is not suitable for mixing.

4.After mixing various wettable powders with other drugs and chemical fertilizers, if it causes a lot of flocculation and deposition, it will also reduce the pesticide power and cause pesticide damage to crops;

5. The effective mixing of pesticides and pesticides, pesticides and organic fertilizers has significant practical effects on the growth and development of crop pest control worms, but the mixed use is generally appropriate for 2 species, and it can also be three when necessary. At the same time, it is also easy to cause drug damage;

6. Microbial strain insecticides, microbial strain fungicides, and microbial strain herbicides cannot be mixed with organic chemical fungicides and pesticides. If mixed, organic chemicals will kill the microbial strains of the microbial strains and zombie drugs.

The main purpose of pesticide mixing is to better save power and improve quality and efficiency. Common insecticides and fungicides are mixed, insecticides and acaricides mixed, or acaricides mixed with fungicides, pesticides, appropriate fast-acting organic fertilizers mixed.

Because the physical properties and functional characteristics of various pesticides are different, some pesticides can have the effect of improving quality and efficiency after mixing, and some pesticides will reduce the effect after mixing, and even cause pesticide damage.

The question that needs to be paid attention to is to see if these two pesticides can be mixed together, if not, do not mix, if they are mixed, it may harm the crops.

1. Pay attention to the fact that there is no adverse chemical reaction between mixed varieties. 2. After the mixing of different pesticide varieties, the crop can not be harmed. 3. After the pesticide is mixed, it does not increase the toxicity and ensures the safety of people and Fenfen.

Fourth, the mixing should be reasonable, including the reasonable collocation between varieties, such as the control of grasses in soybean fields, and the use of grazing and covering grass can be controlled.

We must pay attention to the nature of pesticides, the acidity and alkalinity of different types of pesticides are not the same, we must pay attention to the variety of mixed varieties, we need to pay attention to safety issues, not all pesticides can be mixed.

We must pay attention to the proportion of mixing, but also should pay attention to the dosage, do not have a chemical reaction when mixing, a round of years old must understand the properties of pesticides, in the process of use should also do a good job of cracking the protection of people, do not come into contact with **, must wear a good protective clothing.

You should pay attention to the proportion of pesticides, but also pay attention to the combination with water, but also pay attention to the way of use, but also pay attention to protect your own health.

Be sure to pay attention to the composition of pesticides, and the time of Baobi cache is not too long, if the two pesticides are mixed together, there is a particularly serious sediment regret mold, then it will not seep into the void can be used.
