1. Spray method : pesticide preparations for liquid use (except for ultra-low-volume sprays) such as emulsifiable concentrates, wettable powders, and soluble powders are prepared by adding water to prepare emulsions, solutions, and suspensions for spraying. The method is called a spray method.

Note: First, the choice of sprayer, to perform well, to ensure the quality of the spray. Second, there is a thick wax layer on the surface of the plant, which is not conducive to liquid application, and additives such as penetrant can be added. Third, pay attention to the water quality of the water, and choose clean water (well water or river water). The fourth is to pay attention to avoid environmental pollution.

2. Powder spraying method : a spraying method that uses a dusting machine or a dusting machine to spray powder or dust, and a gas stream to blow off the pesticide powder and deposit it on the crop. Matters needing attention: choose good quality powder spray medicine; pay attention to the influence of environmental conditions, windy days are not suitable for spraying, powder can not be damp and so on.

3, the method of application : throwing or spraying the application of granular pesticides. Mainly used for soil treatment, paddy application or crop heart application. In addition to granules, other pesticides need to be formulated as toxic soil or poisonous fertilizer. Attention should be paid to the quality of the mixture, and the mixture of pesticides and fertilizers should not be stacked for too long. The time of giving is to be mastered. The application of paddy field requires the rice field to be dewed to prevent the poisonous soil from sticking to the rice leaf and causing phytotoxicity. Sprinkle insecticide requires dew.

4, pouring method : a certain concentration of liquid is evenly poured onto the crop, the liquid is mostly deposited in the lower part of the crop, which is a method of application of rice pest control in the south. It should be noted that the safety and diffusion of the drug, when the safety of the drug is not good, it is not suitable to use the pouring method. The depth of the water layer is also an important factor affecting the insecticidal effect.

5. Irrigation method : a method of applying a certain concentration of liquid medicine into the root zone of plants. This method is mainly used to control pests and diseases of crop roots, such as underground pests and melon wilt. The influencing factors are the systemic properties of the main agent itself.

6. Seed dressing method : The method of uniformly mixing the powder or the liquid and the seed in a certain ratio is called the seed dressing method. Seed dressing can effectively control underground pests and diseases transmitted through seeds. Note: First, the medicine and seeds must be mixed evenly. Second, the agent must be able to adhere more firmly to the surface of the seed and dry quickly, or rarely fall off.

7. Seedling impregnation method : It is a method of using a certain concentration of the agent to impregnate seeds or seedlings, which is commonly used in the prevention and treatment of certain species of diseases and the use of plant growth regulators. It should be noted that the temperature, the concentration of the chemical solution, and the processing time are interrelated. Secondly, the newly germinated seeds or seedlings are generally sensitive to the agents, especially the roots are most obvious, and the treatment is extraordinarily cautious to avoid phytotoxicity.

8. Poison bait method : use the bait that can induce harmful creatures to feed, plus a certain proportion of stomach poisons mixed into toxic bait or poisonous soil to trap harmful organisms. It is better to change the bait frequently in use.

9. Smear method : a method of applying a high-concentration liquid to a plant by applying a high-concentration liquid through a certain device. Note that the selection of the agent must have a strong systemic conductivity, and the second application site is conducive to plant absorption.

10. Fumigation method : The method of using Dong steaming agent to generate poison gas or gasification in a closed or relatively closed place at normal temperature to prevent pests and diseases, mainly used in warehouses, cars, greenhouses and other places.
