Pest control is always a crucial part of all stages of agricultural production. For many farmers, understanding and mastering pest control techniques is the key to ensuring the healthy growth of crops and increasing yields. Among them, propylene ether, as a broad-spectrum insecticide, is widely used in the control of various pests because of its high efficiency and low toxicity. This article will detail the role and application of pyripropyl ether in pest control.
1. The basic characteristics of pyripropyl ether
Pyryl propyl ether, chemically known as xxxxx, is a highly selective insect growth regulator. It can effectively inhibit the ecdysone receptor in the pest's body, causing the larvae to molt early, or produce deformities and death. This characteristic makes pyripropyl ether have unique advantages in the control of pests, such as non-target biosecurity, environmental friendliness, etc.
2. The main pest species controlled by pyridyl ether
1.Aphids: Aphids are one of the common pests in agricultural production, they suck plant sap by stinging, causing plant growth to be stunted. Pyripropyl ether has a good control effect on aphids, which can prevent their normal molting, so as to achieve the purpose of controlling the population.
2.Whiteflies: Whiteflies are also a common agricultural pest, which can suck plant juice and spread viral diseases, causing serious damage to crops. Propylene ether is also effective in controlling whiteflies and reducing their population density.
3.Scale insects: Scale insects mainly parasitize plant leaves, causing them to turn yellow and fall off. Propylene can interfere with the molting process of scale insects, thereby reducing its harm.
4.Flies: Fly pests not only directly harm crops, but also spread diseases. Pyripropyl ether has a significant effect on the control of fly pests and can effectively reduce its population.
3. How to use propylene ether
1.Spray method: Pyripropyl ether is prepared into a spray solution according to the recommended dosage and sprayed directly on the affected crops. When spraying, ensure that the front and back of the leaves and around the plant are evenly covered to enhance the control effect.
2.Seed treatment: For some seed-borne pests, pyripropyl ether can be mixed with seeds for seed treatment prior to sowing. This can effectively prevent the occurrence of pests at the seedling stage.
3.Soil treatment: For underground pests, pyripropyl ether can be formulated into a solution of a certain concentration for soil treatment. This can effectively control underground pests such as root maggots and ground tigers.
4.Fumigation method: For some well-sealed facility agricultural environments, the fumigation effect of pyridyl ether can be used to fumigate the greenhouse or greenhouse to kill the pests hidden in the soil or substrate.
5.Greenhouse gas release method: pyridyl ether is released into the greenhouse in the form of greenhouse gas through specific equipment, and its gas stability is used to stay in the greenhouse for a long time, so as to achieve the effect of continuous pest control.
4. Precautions for the use of pyridyl ether
1.Safety interval: A certain safety interval should be maintained after the use of pyripropyl ether to ensure the safe harvesting of crops. Depending on the crop and the concentration of pyripropyl ether used, the safety interval may vary.
2.Reasonable rotation: In order to delay the development of pest resistance, the continuous use of the same pesticide should be avoided. It is recommended to use agents with different mechanisms of action in a reasonable rotation.
3.Avoid applying pesticides during high temperature periods: Pyripropyl ether is easy to decompose and fail under high temperature conditions, so it should be avoided during the noon period when applying pesticides. The best time to apply the pesticide is in the morning or late afternoon.
4.Protection of natural enemies: Pyridafen is relatively safe for non-target organisms, so the harm to natural enemies should be minimized when controlling pests. By rationally choosing the application time and dosage form, the impact on natural enemies can be reduced.
5.Storage and transportation: Pyripropyl ether should be stored in a cool, dry and well-ventilated place, away from fire and heat sources. It is necessary to prevent impact and crushing during transportation to ensure safety.
6.Comply with operating procedures: Personal protective equipment such as protective clothing, gloves and masks should be worn when using pyridyl ether. During the application process, direct contact with the liquid should be avoided** and eyes. In case of accidental contact with ** or eyes, rinse immediately with plenty of water and seek medical attention promptly.
7.Waste disposal: Used spray containers and residual chemical solutions should be properly disposed of to avoid pollution to the environment. It is advisable to dispose of the waste by ** or to a professional organization for disposal.
8.Comply with pesticide management regulations: When using pyripropyl ether, local pesticide management regulations should be followed to ensure that pesticides are used legally and compliantly. If you have any questions or need technical support, it is advisable to consult your local agricultural department or professional body.
In summary, propylene ether, as a high-efficiency and low-toxicity insect growth regulator, has a wide range of application value in agricultural pest control. Through the rational use of pyridyl ether, the occurrence and damage of a variety of common pests can be effectively controlled.
