What should be paid attention to when using pesticides

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.

1) When dispensing, the dispensing personnel should wear rubber gloves and must weigh the liquid medicine or powder according to the dosage and measuring tool on the instructions. Do not increase the dose arbitrarily. The seeds should be mixed with tools, and it is strictly forbidden to mix the medicine by hand.

Mixed seeds should be sown mechanically as much as possible. If sowing by hand, protective gloves must be worn to prevent poisoning.

2) When dispensing medicines, stay away from residential areas or drinking water sources. Strictly prevent pesticides from being lost or accidentally eaten by people, animals and poultry.

3) When using a manual sprayer for spraying, check whether the switch, joint, nozzle, etc. are tightened before spraying. The liquid medicine in the medicine barrel should not be too full, so as not to shake out the barrel and pollute the applicator body; Spraying should be carried out alternately, and the left and right sides should not be sprayed at the same time; It is forbidden to spray when the wind is strong at noon and the temperature is high; After spraying, clean the sprayer, gauge, etc., and store them in the designated place. The rinsed waste should be disposed of away from homes, water sources, and crops.

Containers used to measure pesticides must not be used for other purposes.

4) Fields that use highly toxic pesticides should be clearly marked, and grazing, mowing, and digging wild vegetables are prohibited for a certain period of time.

5) It is forbidden to use drugs for frail and sick, ** patients, and pregnant women. Children should not be brought into the pesticide spraying site when taking medicine.

6) If the sprayer has symptoms such as headache, dizziness, nausea, vomiting, etc., he should immediately leave the application site and send him to the hospital for diagnosis and treatment in time. (1) Accurately check the pesticide application area, and calculate the dosage and application solution according to the pesticide dosage recommended by the pesticide label or the recommendation of the plant protection technician.

7) Operate in the shed and accurately measure pesticides with special weighing instruments. After taking pesticides, seal the original pesticide packaging and store it safely. Pesticides should always be kept in their original packaging before use.

8) It should be used and matched, and should not be stored for a long time; If it is stored for a short period of time, it should be sealed and kept by a special person.

9) The dosage of pesticide application solution should be determined according to different application methods, control objects, fruit tree varieties, growth periods, etc.

10) The preparation of pesticides should be made of clean water without impurities, and the water should not be directly taken from the equipment used to prepare pesticides.

11) Pesticides should be prepared in accordance with the pesticide formulations and methods recommended on the pesticide label.

12) Dilution should be carried out by the "secondary method": Pesticides diluted with water: first dilute the pesticide preparation with a small amount of water into the "mother liquor", and then dilute the "mother liquor" to the required concentration.

Solid carrier dilution of pesticides: pesticide preparations are evenly diluted into "master powder" with a small amount of dilution carriers (fine soil, fine sand, solid fertilizer, etc.), and then diluted to the required amount.

13) The preparation of ready-to-use pesticides shall be carried out in accordance with the provisions of the pesticide label or under the guidance of technical personnel.

There are many aspects that need to be paid attention to in the use of pesticides, and the following is a brief introduction.

The first point is to wear protective equipment as much as possible when using pesticides to prevent pesticide poisoning. We all know that many types of pesticides are toxic, and even some pesticides are highly toxic. For example, some pesticides will cause itching, redness, swelling, allergies and other reactions after contact, if the pesticide accidentally penetrates into the wound, it may cause serious poisoning.

Some pesticides are volatile and may burn the respiratory tract when they enter the body's respiratory tract, or even cause people to go into shock due to shortness of breath. Therefore, in the process of using pesticides, we must wear protective equipment to prevent our own contact with pesticides, and also wear masks to prevent poisoning due to excessive pesticide inhalation.

The second point is that pesticides should be sprayed in the right weather conditions, and using pesticides in the wrong weather conditions may not yield satisfactory results. In fact, under what circumstances pesticides should be used is also a technical job, such as using pesticides before a thunderstorm, then due to the dilution of pesticides by rain, it will definitely reduce the efficacy of pesticides, and the purpose of using pesticides cannot be achieved. Or if pesticides are used in hot weather, the effectiveness of the pesticides will also be affected due to the evaporation of water.

In addition, if the temperature is very high, it will also increase the risk of poisoning for workers, which will lead to some production safety accidents.

The third point is to pay attention to the ratio between pesticides and water, otherwise the dilution of pesticides is not normal, and the efficacy will definitely not be normal. Many people may think that increasing the concentration of pesticides when using pesticides will quickly kill many pests and weeds and improve economic benefits. However, if some pesticides are used in excess, they will not only kill pests and weeds, but also kill crops as well, which is definitely not worth the loss.

Moreover, this will also increase the amount of agricultural residues in crops, affecting our food safety. Of course, if you deliberately reduce the dosage because you are afraid of pesticides, it is not advisable, which will definitely reduce the efficacy and fail to achieve the use effect.

During use, you should pay attention to wearing gloves, and then dilute it with water, preferably in the morning, so that the effect will evaporate faster.

Well water must not be used, protective measures must be taken, the concentration of pesticides should be paid attention to, pesticides should also be used in a targeted manner, and pesticides should not be abused.

Pesticides are essential items in agricultural production, but pesticides need to be used according to the instructions, used in a certain proportion, and the pesticides that have not been used up should be properly preserved.

First of all, it is necessary to pay attention to the appropriate medication standards, and then after the emergence of serious pests and diseases in crops, we must use agriculture in a timely manner, and we must understand the basic operation, and we must do a good job of personal protection.

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.

When using pesticides, you need to pay attention, you must dilute them first, you must do a good job of protection when using pesticides, wear gloves, and use them in the wind, not spray them on your body.

Be sure to protect yourself when using pesticides, and you should wear a mask. Do not use pesticides in a confined space, when spraying pesticides, be sure to mix with water in a certain proportion to pesticide water, never spray pesticides on the leaves of crops, and water more after spraying pesticides, it is best not to use pesticides on rainy days.

Be sure to pay attention to safety, and be sure to pay attention to ways and means, wear protective clothing when spraying pesticides, don't expose your ** outside, don't spray pesticides when the sun is exposed, choose after 5 p.m., you can also choose rainy days.

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.
