Common application methods for pesticides

1. Spraying method: It is a kind of spraying method that is most commonly used to control diseases, pests and weeds in agricultural crops. The pesticide preparations to be used by spraying the medical equipment are diluted with water to the required concentration and then sprayed onto the surface of the crops to form a medicinal film for the purpose of preventing and controlling pests. It is divided into: conventional spray method, low volume spray method and ultra-low volume spray method. Spraying requires spray equipment, water, and good water quality.
2, dusting method: It is using a duster to generate wind to spray pesticide powder onto the surface of crops. Suitable for water-shortage areas or protected areas (in vegetable greenhouses) with high ergonomics, but the open-air dust powder has poor adhesive force and strong expulsion, and the control effect is generally not as good as the spray method. The dusting time in the protected area should generally be in the early morning or in the evening and cloudy all day, otherwise it will not receive the expected results. The disadvantage is that it is easy to pollute the environment.
3, pouring pouring method: is the amount of EC, wettable powder or water, etc., diluted with water, stir evenly, pouring water to the plant or spraying with water. It is mainly used for the prevention and control of pests in small areas. The water consumption is 2-3 times more than that of spraying. It is not suitable for the prevention and control of most large-scale diseases, insects and weeds.
4, spread method: apply to the application of granules and toxic soil. When producing poisonous soil, when 1 agent is a powder, it can be directly mixed with the fine tide soil according to a certain number of parts. When the 2 liquid agent and emulsifiable concentrate are used, first dilute the agent with a small amount of water, and spray it on the fine soil with a sprayer and mix well. Boring 0.5-1 hour after appeasing. Prevent pests on plants should be carried out when the fog is not dry, and control of underground pests should be performed after the fog is dry. Note: Poisonous pesticides cannot be used as poisonous soil.
5. Soil treatment method: In combination with ploughing, the pesticide is applied to the ground by spraying, dusting or spreading, etc., and then turned into the soil layer, mainly for controlling underground pests, nematodes, soil-borne diseases or for treating soil. The insects and cockroaches are also used for systemic application of pesticides, which are absorbed by the roots and transmitted to the ground of the crop to control pests and germs on the ground.
6, seed dressing method: a certain amount of pesticides and seeds mixed in proportion after sowing, can prevent the seeds attached to the pathogen and the underground pests and seedling disease.
7. Impregnation method of seeds and seedlings: The method of impregnating seeds and seedlings with a certain concentration of liquid medicine. The commonly used pesticides are water solvents or emulsifiable concentrates for the prevention and control of pathogens attached to seedling seedlings. Impregnated seeds and seedlings must strictly control the liquid concentration, temperature and immersion time so as to avoid phytotoxicity.
8. Poison bait and poison valley method: Mix the pesticides with stomach poisoning on pests, baits and cereals that the rodents like to eat, and apply them on the ground to prevent pests and rodents that are harmful to the ground. The preparation of poison valley should be preceded by sauteing grains. Or cook it half-cooked and let it dry until it is half dry.
9. Fumigation method: It is a method for controlling diseases and insect pests by using toxic gases produced by volatile pesticides. It is mainly used for the control of diseases and pests in places such as soil, greenhouses, greenhouses, and warehouses. The fumigation method is highly efficient and fast. However, it should be noted that after the fumigation is over, it is necessary to fully disperse the air and to avoid poisoning.
10, smoked method: The main application of aerosol pesticides, ignited pesticides produce smoke dispersed in the air, play a role in the prevention and control of pests and diseases. It is mainly used to control pests and diseases in confined places such as greenhouses, greenhouses, and warehouses. Also pay attention to the need for full aeration after the end of fumigation to avoid poisoning.
11, smear method: The pesticide with systemic absorption is formulated into a high-concentration liquid, applied to the stems, leaves, growth points and other parts of the plant, and is mainly used for controlling pests and drillability with sucking and sucking mouthparts. Pests can also be applied with a certain infiltration of bactericide to prevent fruit tree disease.
12. Injection: After diluting the pesticide to a certain concentration, the pesticide is injected into the plant body with a syringe to prevent and control pests and diseases. Such as the prevention of pests of fruit trees, common hanging bottles hanging fruit trees.
