Is it necessary to wear a mask when spraying pesticides?

It is necessary to wear a mask, because the fine dew left behind by the spray can be inhaled into the nasal passages and is not good for the body.

It is necessary. Because pesticides volatilize, we must wear masks to avoid inhaling the human body, which can cause damage to our bodies.

It is necessary, after wearing a mask, it can play a certain protective role, and if you do not wear a mask, inhalation will cause harm to the human body.

KN100 dust mask.

Users also need to take protective measures when spraying pesticides, wear protective clothing and banana gloves, which can protect individuals well and prevent pesticide liquid from splashing on the surface and being absorbed into the blood. When the user sprays pesticides, it is also necessary to configure the correct configuration in accordance with the instructions of the drug, the precautions and contraindications when dispensing, and must be operated in strict accordance with the instructions, and the illegal operation is prohibited, and the user's health is responsible.

If it is a biopesticide, it is recommended to buy a KN100 dust mask. If it is a pesticide with toxic gases, it is recommended to consult a merchant that sells gas masks.

The protective effect of gas masks depends on 2 aspects. One is the protection level of the poison filter box. The second is how tightly the mask is combined with the face.

Therefore, the mask must be divided into large and small sizes, and the fit of the mask and the face varies from person to person.

The scientific selection of gas masks certified by the GB2890-2009 standard helps to prevent harmful gas damage.

1. Choose a duplex half mask type.

2. Select the corresponding level of the filter box to use. A low rate of protection will lead to physical injury. If there is smoke and dust in the working environment, it is recommended to choose an anti-virus and smoke-proof integrated poison filter box or place a layer of pre-filter cotton on the poison filter box.

3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

4. The mask is divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

5. There are full face masks and half masks. Among them, the most commonly used half mask is to cover the mouth and nose, cover the mouth, nose, and jaw, and it is recommended to use the latter as it is relatively comfortable.

6. It is recommended to choose a breathing mask. Some use a double filter box design, which is relatively easy to breathe.

The potency of most pesticides increases with temperature, so when using high-temperature drugs, care should be taken to reduce the amount of liquid drugs, and in order to produce the effect of touching the top once and twice, the potency of most pesticides will increase with the increase in temperature. Therefore, when using drugs at high temperature stations, care should be taken to reduce the amount of liquid drugs, especially hormonal drugs.

When sprayed above a certain limit, the small droplets on the leaves will condense into large droplets, which then roll down and disperse, which will reduce the amount of pesticide associated with the leaves. The droplets are evenly distributed and have high coverage, which is suitable for watering the surface of plants without droplets. In this way, it is necessary for the spray used to have a good atomization effect and reduce the drug waste.

Medications should not be used in <> high winds. Strong wind is easy to make powdery powder or fog droplets fly with the wind, can not evenly adhere to the surface of the crop, and will also float on the applicator, easy to poison. Spraying chemicals and rainwater can directly flush chemicals, which not only affects the effect, but also causes water pollution.

In general, the chemicals used for seed coating are less affected by rainwater. High temperatures will accelerate the decomposition of pesticides and the volatilization of chemicals, so high-temperature chemicals should not be used. Because crops have a strong metabolism in hot climates, the leaves are open, and chemicals can easily get into objects and cause damage to drugs.

Pesticides such as myelin, suclin, octyl cyanide and other pesticides have a strong toxic effect and can kill the plague 1-2 hours after use. Whether it is grain, oilseeds, melon crops or fruit trees, the use of drugs should be stopped in accordance with the norms before harvesting, in order to avoid human and animal poisoning, when using drugs at high temperatures in summer, attention should be paid to sufficient water mixing to ensure multiple dilutions. The dosage of the potion should be more than 45 kg and should not be overfilled.

When spraying, some farmers like to fill the spray barrel to the brim.

In climates with high temperatures, fog or dew, the drug is easily diluted with water, reducing the effectiveness of balata medications. In addition, in the morning, when the dew is not dry, the temperature is relatively low, and the plague has not yet come out. At present, the spraying effect is not good, the weather is hot in summer, and the metabolism is accelerated.

Protective measures must be taken before using pesticides. Be sure to wear a gas mask, wear long clothes and long pants to avoid pesticide poisoning due to breathing and **penetration.

The first thing is to choose the right concentration, and then be sure to spray on the leaves when spraying, and then you also need to do a good job of ventilation, and you must water in time after spraying pesticides.

Ask about the situation before borrowing: be sure to find out the type and name of the pesticide sprayed last time, and carefully check whether there are drug residues in the sprayer, and do not borrow it for direct use, so as not to affect the efficacy of the drug or lead to drug damage, resulting in unnecessary losses. Before use, be sure to soak it for a long time with laundry detergent, dish soap, etc., rinse it many times to ensure that it is clean, pay attention to observation after spraying, and clean and return it after use.

Be sure to pay attention to cleaning the sprayer, otherwise the mixing of the two pesticides is likely to cause plant death.
