Pyriproxyfen, as a broad-spectrum insecticide, is widely used in the control of various pests due to its high efficiency and low toxicity. This article will explore in detail the role and application of pyripropyl ether in pest control.
I. Main pest species controlled by Pyriproxyfen
Aphids: Aphids are one of the common pests in agricultural production. They suck the SAP of plants by stinging and sucking, which hinders the growth of plants. Pyriproxyfen has a very good control effect on aphids, which can prevent their normal molting and thus achieve the purpose of controlling the population size.
2. Whiteflies: Whiteflies are also a common type of agricultural pest. They suck plant SAP and spread viral diseases, causing serious damage to crops. Pyriproxyfen can also effectively prevent and control whiteflies and reduce their population density.
3. Scale insects: Scale insects mainly parasitize on plant leaves, causing them to turn yellow and fall off. Pyriproxyfen can interfere with the molting process of scale insects, thereby reducing their degree of damage.
4. Flies: Fly pests not only directly damage crops but also spread diseases. Pyriproxyfen has a remarkable control effect on fly pests and can effectively reduce their population size.
II. Usage Method of Pyriproxyfen
1. Spray method: Prepare a spray solution of Pyriproxyfen at the recommended dosage and directly spray it on the affected crops. When spraying, make sure to evenly cover both sides of the leaves and the area around the plants to enhance the control effect.
2. Seed treatment: For some pests that are spread through seeds, Pyriproxyfen can be mixed with the seeds before sowing for seed treatment. This can effectively prevent the occurrence of pests during the seedling stage.
3. Soil treatment: For underground pests, Pyriproxyfen can be prepared into a solution of a certain concentration for soil treatment. This can effectively control underground pests such as root maggots and cutworms.
4. Fumigation method: For some well-sealed facility agricultural environments, the fumigation effect of pyripropyl ether can be utilized to fumigate greenhouses or sheds, thereby killing pests hidden in the soil or substrate.
5. Greenhouse gas release method: Through specific equipment, pyripropyl ether is released into the greenhouse in the form of a greenhouse gas. By taking advantage of its gas stability, it can remain in the greenhouse for a long time, thereby achieving the effect of continuous pest control.
