First of all, we must pay attention to the efficacy, when using pesticides, we must choose the right varieties according to crops, we must do a good job of personal protection when using, and we must also wear protective masks, and we must pay attention to the time of use, and we must avoid the time when the temperature is relatively high.

We should all know that the use of pesticides is inevitable in the process of growing crops. Because crops will produce some pests and diseases, these pests and diseases may make crops lose their harvest if they are not controlled, so these pests and diseases must be killed. What problems should be paid attention to when using pesticides?

First, choose the right pesticides.

We should all know that each pesticide kills different pests and diseases, so farmers must read the instructions of the pesticide when choosing pesticides. Farmers need to determine which pests and diseases this pesticide is effective against, and then they can also ask the staff who sell the pesticides. And there are many varieties of pesticides on the market, their quality is also uneven, and the control objects are also very different.

Therefore, when buying pesticides, you must go to regular stores to buy, do not go to some small stores with no pesticides to buy pesticides, such pesticides have no quality assurance and cannot be used.

2. Use pesticides at the right time.

Farmers can't use pesticides blindly when spraying, which is to use pesticides at any time when crops are growing, which is also incorrect. Because the control period of any pest and disease is limited, farmers must use pesticides when pests and diseases break out, and cannot use pesticides all the time. Farmers can not blindly use drugs, if the drug is too early or too late can not achieve the desired effect, only the use of pesticides in the correct prevention and control period can achieve the desired effect.

And when using pesticides, you should also use an appropriate amount of pesticides, not too much.

3. Techniques for the use of pesticides.

In fact, there are technical requirements for the use of pesticides, such as the ratio of pesticides, and how much water should be mixed with one gram of pesticides. Only the use of pesticides in strict accordance with the operating procedures can achieve the best control effectWhen spraying pesticides, it is best to choose atomized spraying, because this will allow every pest to come into contact with pesticides and will not cause damage to plants.

1.Pay attention to the use of pesticides, 2Pesticide use time, 3The dilution ratio of pesticides, 4Effects on crops, 5impact on the soil, etc.

Attention should be paid to the way of pesticide use, the frequency of pesticide use, the angle of pesticide use, the protection of pesticide use, and the preservation of pesticides.

Pay attention to the composition of pesticides, but also pay attention to the technology of pesticides, pay attention to the method of pesticide configuration, pay attention to the method of spraying, and pay attention to the variety of pesticides.

1. The principle of appropriate amount: the dosage of pesticides should be strictly controlled, and the allocation should be carried out according to the specific situation of the plant. 2. Targeted:

Insecticides cannot be used to kill mites, and herbicides should be paid attention to distinguishing between large and small seedlings. 3. Application method: foliar pests and diseases are sprayed down, and corn borer adopts dim sum and filling method.

1. The principle of moderation

The dosage of each pesticide should be strictly controlled, the amount used is too small, the control effect does not meet the requirements, the dosage is too large, and there will be pesticide damage, so when using pesticides, it is necessary to deploy according to the specific situation of the plant, and do not add blindly.

2. Targeted:

Different pesticides to control pests are different, such as insecticides, can not be used to kill ates, but also can not sterilize and prevent diseases, paddy field herbicides must also pay attention to the size of the seedlings are different, the choice of pesticides is also different, must be targeted to choose pesticides.

3. Application method

According to different control objects, different pesticide application methods are adopted, such as the spray type is for ground weeding and foliar pests and diseases, the upper spray type is aimed at leaf back pests and diseases, the oblique cutting type is aimed at the diseases and pests in the lower part of the rice bush, and the corn borer adopts the method of dim sum and filling the heart.

4. Time of use

When spraying pesticides, be sure to choose a sunny time period, and the temperature should not be too high, otherwise the pesticide will volatilize quickly and fail to achieve the desired effect, it is best to do it at 8-10 am or 4-6 pm.

First of all, we must choose the best pesticides, but also should prescribe the right medicine, when using pesticides, we must pay attention to the ratio and dosage, but also should pay attention to the number and cycle of pesticide use, and then do not use pesticides in rainy weather, otherwise it will affect the effect of pesticides.

When using pesticides, you must do a good job of protection, and be sure to wear masks and gloves. When using pesticides, do not use them in a confined space, the temperature should not be too high, and after using pesticides, they must be cleaned up in time, and hands must be washed.

To stay away from water sources, it is necessary to choose the right concentration, the time of spraying should also be grasped, and the composition of pesticides should be understood, and it is necessary to avoid choosing more toxic ones.

First of all, it is necessary to do a good job of personal protection, and it is necessary to use drugs in accordance with the norms, and at the same time, when there are pests and diseases or weeds, it should be used in time, and the appropriate agents should be selected according to different crops, and the time of use should also be paid attention to.
