High temperature weather is easy to appear drug damage, what methods can reduce the occurrence of drug damage?

In the season of high temperature and concentrated precipitation, pest control has become the main task of agricultural production. In high temperature weather, the water in the agent is easy to volatilize, resulting in high local concentration of the agent, and enhanced absorption capacity of the leaves. It is susceptible to drug damage. How does mixing reduce the occurrence of drug injury?

The causes of drug damage mainly focus on the following points. High temperature in summer is the main cause of drug damage. Therefore, it is necessary to avoid periods of high temperature. Generally before 10:00 a.m., but must wait for dry dew, and after 3-4:00 p.m.

Please note that if IT HAS BEEN raining or cloudy FOR several days, that is, there is no sunshine, and there is sunshine suddenly, it is not suitable for medication at this time. It had to wait until the next day, because the branches and leaves were very tender and easy to take medicine. It is easy to understand that you should not inject drugs on windy days. Wind can float the drug to the place where it is injected, causing the drug to be reused and increasing the likelihood of drug damage.

First, the concentration is not well controlled. Each drug has its own concentration. We should strictly follow the drug instructions for dilution, should not increase the concentration of drugs. In addition, some people in rural areas may feel that current drugs are not as effective and must be used in higher concentrations to be effective.

In fact, it is not the efficacy is not good, but the pests and diseases have developed resistance, which is closely related to our long-term monotherapy. In any case, however, the drug must be used in the prescribed concentration. If the concentration is too high, it is easy to cause drug damage.

Do not add the dose at random concentration, and do not reuse to avoid drug damage. If the crop has antibodies, it can be treated with another drug. In case of drug damage, spray with water, neutralization method and other methods can be used to timely rescue. For specific methods, please consult relevant experts.

Spraying should avoid high temperature period, because high temperature period due to the strong volatile effect of drugs is not conducive to human body, easy to poisoning. The second is the rapid evaporation of the drug solution after spraying, which can lead to high concentrations of local chemicals in the crop that can cause drug damage.

For example, we are used to spraying at night, when the temperature is not particularly high, and the crop has plenty of time to absorb the drug after spraying. It is also possible to spray inside before 10 a.m. In addition, medication intervals were not noted. In fact, the interval between drug use is equivalent to applying higher concentrations of drugs to crops, which also contributes to drug damage problems.

There are many kinds of insecticides, such as fungicides, insecticides, herbicides, foliar fertilizers, etc. Whether or not they can mix with each other is usually understood by the specification of the agent. We should be bold in using those that can be mixed, and we should not abuse those that cannot be mixed. In a word, you must read the instructions carefully before taking the medicine.

The mixing order of pesticides. Pesticides generally include wettable powders, crystalline particles or solids, suspensions, liquids, etc. First of all, prepare mother liquor, use a washbasin as a container, form a half basin of water, add wettable powder and stir evenly, and then add suspension stir evenly, and then pour into the liquid stir evenly.

If the solid medicine needs to be dissolved in water beforehand, pour it into a basin and stir evenly. Then, fill the sprayer with half a bucket of water, keeping an eye on the water, then pour the mother liquid from the wash basin into the sprayer and add enough water to stir well. This means accompanying the mother liquor and then diluting it twice.

As the saying goes, prevention is better than remedy. If you are unsure of the pesticide mix, separate sprays should be staggered for a period of time. Don’t think of bombing just because it’s hot. Although it saves energy and trouble, it will cause problems in the future. However, these crops must be treated with drugs, and the harm is unavoidable. This happens every year. What we should do is try to avoid it.

As for pesticide mixtures, many agricultural technologists offer dispensing principles. As long as it is strictly followed, there are generally no major problems. Specifically, there are questions about the sequence of pesticide mixtures and the pharmaceutical properties of pesticides. It would be nice if we were clear. It must be remembered that whatever pesticide is configured, it should be configured and applied immediately.

Should not be prepared and used for a long time. It deteriorates and causes unspeakable physical and chemical reactions. Another method is to add water first and then add medicine. Don’t get the order wrong. First pour half of the water into the medicine bucket, then pour the pesticide into the medicine bucket, dilute it, then pour the other half of the water, and then stir well. Finally, the order of various medicines and fertilizers.

It must be remembered that micronutrient fertilizer, water-soluble fertilizer, wettable powder, water-dispersed particles, suspension agents, microemulsion, water, emulsion and so on add one and stir. It is recommended not to eat too much medicine and fertilizer bucket in principle can use three medicines and fertilizer. It’s hard to know more about drugs, and there may be unknowns.

Please note that the cause of drug damage is improper drug use. Some people did not read the pesticide instructions carefully, while others made fake and inferior pesticides. Another possibility is that crop susceptibility to pesticides varies at different stages of growth and development. Temperature, humidity and soil are all factors to consider.

There are many treatments. If there is drug damage, we can use dilution to reduce the drug damage, or spray water directly in the spray bucket three or four times, or use some chemicals to neutralize the acid base, or use potassium permanganate, because many pesticides will break down under the strong oxidation of sodium permanganate.
