How to use pesticides

Commonly used application methods are as follows:

1. Spraying method: It is the most commonly used pesticide application method for the prevention and control of field crop diseases, insects and weeds. The pesticide preparations used in liquid form are diluted with water and sprayed on the surface of crops to form a film to achieve the purpose of controlling pests and diseases.

Spraying requires a sprayer, a water source, and good water quality.

2. Powder spraying method: It is to use the dust sprayer to generate wind power to spray pesticide powder onto the surface of crops. It is suitable for water-scarce areas, with high work efficiency, but the powder has poor adhesion and strong etherealness, and the prevention and control effect is generally not as good as that of spraying, which is easy to pollute the environment.

3. Pouring method: It is a quantitative amount of emulsifiable concentrate. WP or water agent, etc., dilute with water, stir evenly, and pour water on the plant or spray rain with a water pump. It is mainly used for the control of pests in paddy fields, and the water consumption is 2-3 times more than that of spraying, which is not suitable for the prevention and control of most diseases.

4. Spreading method: suitable for the application of granules and poisonous soil. When making poisonous soil, when the agent is powder, it can be directly mixed with fine soil according to a certain number of parts; When the liquid agent, first dilute the agent with a small amount of water, spray it on the fine soil with a sprayer, mix it evenly, sprinkle the poisonous soil to control the pests on the plants, and the pests on the plants should be carried out when the fog water is dry, and the control of underground pests should be carried out after the fog water is dry.

For highly toxic pesticides, they cannot be made into poisonous soil and sprinkled.

5. Soil treatment method: combined with tillage, the pesticide is sprayed, sprayed or sprinkled on the ground, and then turned into the soil layer, which is mainly used for the prevention and control of underground pests, nematodes, soil-borne diseases and insects and pupae in the soil, and is also used for systemic agent application, which is absorbed by the roots and transmitted to the above-ground division of crops to prevent and control pests and pathogens on the ground.

6. Seed dressing method: a certain amount of pesticide is mixed with the seed in proportion and sown after sowing, which can pre-treat the fungus attached to the seed, underground pests and seedling diseases.

7. Seedling impregnation method: the method of using a certain concentration of liquid medicine to impregnate seedlings, and the pesticides generally used are water solvent and emulsifiable concentrate, which are used to prevent and control the pathogens attached to the seed seedlings. The concentration, temperature and impregnation time of the impregnated seedlings should be strictly controlled to avoid pesticide damage.

8. Poisonous bait and poison grain method: the pesticides with stomach toxicity and the bait and grains that pests and mests like to eat are mixed well, and applied to the ground for the prevention and control of pests and pests that harm the ground.

9. Fumigation method: It is the use of toxic gas produced by volatile pesticides to prevent and control pests and diseases, mainly used for pest control in soil, greenhouses, greenhouses, warehouses and other places.

10. Fumigation method: the main application of tobacco pesticides, the pesticide is ignited to produce smoke and disperse in the air, which plays a role in the prevention and control of pests and diseases. It is mainly used to prevent and control pests and diseases in closed places such as greenhouses, greenhouses, and warehouses.

11. Foaming method: the endogenous pesticide is prepared into a high concentration of liquid medicine, which is applied to the stems, leaves, growth points and other parts of the plant, mainly used for the prevention and control of pests and bor-boring pests with piercing and suction mouthparts, and can also be applied with fungicides with a certain penetration to prevent and control fruit tree diseases.

1. Local spraying. When local crops are seriously damaged, targeted spraying can be adopted, which not only controls the occurrence of pests, but also reduces the use of pesticides, reduces production costs, and more importantly, protects natural enemies and insects.

2. Ground spraying. Spreading or spraying pesticides on the ground can not only kill pests, but also reduce damage to natural enemies.

3. Selective medication. The use of agents with a killing effect can not only play a good role in prevention and control, but also protect natural enemies.

4. Use microbial preparations to control pests. For example, Beauveria bassiana preparations are used to control grub pests.

5. Mix pesticides. The mixed use of pesticides with different mechanisms of action can not only delay the emergence of crop resistance, but also enhance drug efficacy, reduce the amount of pesticides and reduce costs. For example, the combination of delayed-acting chlorpyramide and fast-acting pyrethroid pesticides can speed up the knockdown rate of the drug to insect pests, reduce the killing of natural enemies, and reduce the amount of pyrethroid pesticides.

6. Comprehensive prevention and control. Combine chemical prevention and control with agricultural prevention and control and biological measures, implement comprehensive prevention and control, do not use pesticides as much as possible, reduce the amount and frequency of pesticides, protect the safety of natural enemies, and ensure the normal growth and development of crops.

There are skills in medication, and safe medication is the key. The majority of farmers should follow the above points when using drugs to avoid safety accidents.

Ground pests can be sprinkled on the surface to control underground pests. Ground pest clear is a kind of toxic pesticide that specializes in the prevention and control of underground pests, the prevention and control objects of ground pest clear are mainly tigers, grubs, mole crickets and needleworms in the farmland, these four underground pests, these pests are generally hidden in the soil, causing damage to the root system of crops, the use of ground pests to clear the surface of the land, through the infiltration of the surface, it will play a medicinal effect in the soil.
