What are the contraindications for the use of pesticides in summer?

It is necessary to pay attention to safety, and do not choose pesticides with relatively high concentrations when fertilizing, be sure to grasp the appropriate amount, and it is necessary to choose the right time to spray pesticides, and then you also need to insist on using pesticides, pay attention to wearing good clothes, gloves, and masks.

The taboo is that when spraying pesticides, you must avoid harm to your body, do not eat pesticides by mistake, do not sprinkle pesticides on your body, spray pesticides on crops, and spray less pesticides on crops.

You need to pay attention to the temperature, you need to pay attention to the growth of plants, you need to take precautions, you need to wear a mask, you need to wear long-sleeved clothes, and you need to wear goggles.

It must be used safely, not too much spraying, pay attention to the amount of medicine, but also pay attention to the time, to apply pressure evenly, and not to repeat spraying, these are all important to pay attention to.

Agricultural production must develop different planting methods according to different seasons, and the temperature is high in summer, and pesticides are more likely to have chemical reactions, so there are many places that need to be paid attention to. For example, when using pesticides in summer, we must pay attention to the safe use of drugs, strictly control the dosage, try not to use drugs when the sun is the most toxic, and mix pesticides reasonably.

Safe pesticide application covers a wide range, for example, it is best not to use highly toxic pesticides, which may affect the health of humans and animals while affecting crops. Pesticides with strong acids and alkaline may corrode people and cause hidden dangers to people's physical safety. In the process of medication, it is necessary to keep the medicine to avoid poisoning of humans and animals due to misuse.

If the temperature is too high in summer, we must avoid spraying pesticides at high temperature times at noon, so as not to affect the human body due to the toxicity of pesticide volatilization. In the process of preparing pesticides, try not to use sewage and well water to avoid affecting the efficacy of pesticides.

The continuous spraying time of pesticides should not be too long, and the best time to apply pesticides in summer should be in the morning and evening. High temperature may also affect the efficacy of pesticides, and when the temperature is very high, pesticides can easily volatilize after spraying, which will reduce the efficacy of pesticides. In addition, the use of pesticides at high temperatures will increase the burden on the water supply of crops due to the transpiration of plants, and there may be a risk of pesticide damage.

If you want to control pests, it is best to spray them in the evening, which is generally active in the evening in the hot summer heat.

In the process of spraying pesticides, we must strictly control the dosage, no matter what brand, what nature of pesticides, should be used under the recommended dosage, so as not to cause damage or affect the efficacy. In the process of medication, the spraying should be uniform and thoughtful, and no respray or leakage spraying. There are many pesticides on the market, different pesticides have different control ranges, according to the specific reaction of crops, choose the right pesticides, the right medicine can be effective faster.

It should be noted that there should not be too many pesticides, and we should also pay attention to a percentage when using pesticides in summer, and when spraying pesticides, we should also pay attention to our personal life and health.

Any pesticide should be used according to the recommended dosage, pay attention to the application time, should not be applied at high temperatures, there are many varieties of pesticides, the characteristics are different, should be based on the prevention object, choose the best pesticide.

First of all, we must pay attention to safety, when spraying pesticides, we must avoid high temperature weather, and we must choose the right dosage, we must pay attention to the appropriate dose, and we must prescribe the right medicine after the problem, and then we must deal with it in time.

When using pesticides in summer, you should pay attention to wearing gloves and then use them in the morning, so that the effect is better.

How to use pesticides rationally in summerImprove the utilization rate of pesticides

Pay attention to the adhesion of pesticides, when outdoor crops use pesticides, they should choose ones that are resistant to precipitation erosion, which have a long residual time on the surface of the main stem, while granules and liquids are relatively weak. For many crop types, there is a plush or excessively thick wax layer on the leaf surface, such as bud rice, shallots, ginger, yams, etc., and the liquid is easy to appear on the plush and fruit wax layer.

Moderately reduce the concentration value of the agent

The medicinal power of most pesticides will increase with the rise of temperature, so special attention should be paid to reducing the amount of medicine used during high temperature seasons, especially the agents of hormone drugs, and the heavy amount of drugs is easy to cause fertilizer damage. Therefore, it is necessary to effectively adjust the concentration value of the agent according to the temperature change.

Pay attention to the quality of the spray

In fact, when the crop is sprayed with pesticides, the pesticide particles that can be adhered to the surface of the crop leaves are to a certain extent, and when the spraying amount exceeds a certain extent, the tiny particles on the leaves will condense into solid particles and roll down and flow out, which reduces the pesticide adhesion on the leaves. The spray method generally requires that the quality particles of the sprayer are evenly distributed and have a high penetration rate, and it is advisable to not drip on the surface of the wet main stem, so it is necessary to use the sprayer to do the atomization effect and reduce the consumption of the potion. At the same time, it is necessary to pay attention to the overall position of spraying, especially when some insect pests like to lay eggs on the back of the leaves, and special attention should be paid when spraying pesticides.

Effective spraying to avoid poisoning

Dispensing, spraying to avoid pesticides contact with the skin, the use of volatile pesticides must wear protective masks, at the same time can not be sprayed in the summer afternoon high temperature, summer spraying should be carried out before 9 o'clock in the morning or after 4 o'clock at noon, to prevent the generation of fertilizer, spraying time can not be too long.

[Summary].

Pesticides are a more commonly used way to prevent pests and diseases in the process of planting vegetables, fruits, trees and flowers, but in the summer high temperature weather, the use of pesticides should pay attention to many aspects, not to pay attention to not only affect the control effect, but also affect the health of spraying pesticides.

In the summer, you should choose some pesticides with strong rain resistance, so that when it rains, you can also accompany the spraying, and when spraying is at 5 o'clock in the afternoon, you can also add some nutrient solution to the car.

In the summer, we need to use the right ratio of pesticides to make the stool with pesticides, and it is also necessary to choose the right time to spray pesticides, and it is best not to choose to spray on rainy days.

You must not use more pesticides in the summer, use them when the weather is fine, and it is best not to use them when it rains, otherwise it will damage the soil.

Growers friends, due to the high temperature and rain in summer, is the season of high incidence of crop diseases and pests, in order to improve the efficacy and personal safety of pesticides, I hope that farmers and friends should pay attention to the following points when using pesticides:

First, it is not necessary to use hazardous chemicals and high residue pesticides. At this stage, high-efficiency minimally toxic pesticides can already replace high-residue pesticides in hazardous chemicals, and there is no need to use these pesticides that are facing elimination, high toxicity and poor drug power.

Second, pay attention to the spraying time and try to avoid the high temperature period (11-15 o'clock). When using medicine at high temperatures, people will be poisoned, and food crops are also easy to cause fertilizer damage, and the control effect is not very good, so it should be minimized. Endogenous pesticides should be used.

Such as dimethoate, methamphetamine, instant extinguishing and other pesticides, because this kind of pesticide in 4 to 5 hours after use, more than 80% of the active ingredients can be absorbed by the crop into the internal tissue, even if it rains can kill pests and bacteria.

Third, don't get tired and take medicine. The old, weak, women and children have poor resistance and are not suitable for participating in disease prevention and insecticide work. If you feel tired from taking medication, you should clean up and rest on time.

Fourth, it is to pay attention to the safety protection of wearing clothes and shoes, and reduce the exposure of spraying.

Fifth, pay attention to the wind frequency and do not spray in the wind. When there is a hurricane, stop spraying.

Sixth, pay attention to the maintenance of equipment before using medicine, you can first use cold water to clean and use a sprayer to avoid liquid leakage, and can avoid the harm of residual pesticides to food crops.

Seventh, it is an effective Zi's liquid preparation, which prevents blindly following the trend to increase the dosage and increase the risk of fertilizer damage of food crops.

Eighth, it is to read the label carefully before using the drug, and decisively do not use pesticides that have no label or vague labels. Avoid adverse effects caused by misuse.

Nine, the fiber barrier is to store pesticides to prevent the elderly and children from touching or ingesting by mistake.

10. If you find food poisoning symptoms, you should immediately send them to the hospital for outpatient treatment, and carry the label of commonly used pesticides.
