Applying in rainy days can also be efficient
First, the use of systemic pesticides. Systemic pesticides can enter the plant through plant roots, stems, leaves, etc., and are imported into other parts. According to reports, one hour after the spraying of tricyclazole, it did not affect the efficacy. About one hour after the application of the phosphonamine, about 50% of the drug amount entered the crop tissue. A few hours after the administration of the systemic pesticides, omethoate and monocrotophos, most of them are absorbed into the tissues by the plants, and the effects are less affected by rainfall. Kung Fu emulsifiable concentrate has strong penetrating power and anti-scouring force, and is also suitable for rainy season application.
Second, the selection of fast-acting pesticides with greater toxicity. Aphids on crops can be killed in a few minutes after application. The phoxim, methomyl, cotton boll, jingling, guangkewei and pyrethroid pesticides have a strong contact action and can kill a large number of pests within 1 hour to 2 hours after application. Although the toxicity of such pesticides is large, it can be greatly reduced by dilution with rainwater after application.
Third, the use of microbial active pesticides. The application of chemical pesticides during the rainy season will reduce the efficacy of the pesticide more or less, and the application of microbial pesticides will increase its efficacy. For example, fungi, bacterial pesticides, the application effect is poor under dry conditions, only in the case of high humidity, especially in the presence of rain or dew, the reproduction speed will be accelerated, and the insecticidal effect will be improved.
Fourth, the use of rain-resistant water-based pesticides. For example, Bordeaux mixture, Green Debao, green lactone, Jinggangmycin, etc., 2 hours to 3 hours after application, even in the case of moderate showers, does not affect the application effect.
5. Add an adhesive to the liquid. When the pharmaceutical liquid is used, an appropriate amount of an adhesive such as washing powder or saponin can enhance the adhesion of the pesticide on the crop and the surface of the pest. It is not easy to wash the medicine in case of moderate or small rain after application. Adding an appropriate amount of highly adhesive mineral oil or vegetable oil, soy flour, starch, etc. to the powder can significantly improve the adhesion.
Sixth, improve the application method. According to the performance of the drug, suitable application methods, such as systemic insecticides, can be used to avoid rainwater scouring and prevent pesticide loss. Appropriate application methods are adopted according to the law of occurrence and activity of pests and diseases. The pests that feed at night, such as rice leaf roller, can be applied at dusk to improve the efficacy.
An electric Gate Valve is a type of valve that uses an Electric Actuator to open and close the gate of the valve. The gate is a flat or wedge-shaped piece that moves perpendicular to the flow of the fluid. When the valve is open, the gate is lifted or pushed aside to allow the fluid to pass through. When the valve is closed, the gate is lowered or pressed against the valve seat to prevent the fluid from flowing.
Electric gate valves are commonly used in industrial applications where precise control of the fluid flow is required. They are often used in pipelines, water treatment plants, oil and gas refineries, and chemical processing plants. The electric actuator allows for remote control of the valve, which can be operated from a control room or a computerized system. This makes it easier to monitor and adjust the flow of the fluid, which can improve efficiency and reduce the risk of leaks or spills.
