Trunk injecting pesticide for preventing corythucha ciliate, and preparation method and application thereof

Abstract

The invention discloses a trunk injecting pesticide for preventing corythucha ciliate, and a preparation method and application thereof. The trunk injecting pesticide for preventing the corythucha ciliate is long in effective time, and compared with sprayed pesticides used at present, the trunk injecting pesticide is good in effect, saves both time and labor, and avoids pollution to the environment; the preparation method is simple in process and low in costs; the application is free from the influence of weather and tree body heights, and the pesticide enters a plant body completely, does not hurt natural enemies, and can be used for a long time. The trunk injecting pesticide disclosed by the invention is durable and stable in effect; hydrolysis is difficult to happen; the defect that current trunk injections need preparing while used is effectively avoided; and the using burden of a user is relieved, so that the trunk injecting pesticide is suitable for industrial production. The trunk injecting pesticide for preventing the corythucha ciliate is prepared from the following raw materials in percentage by weight: 1 to 50 percent of thiacloprid raw powder, 0.1 to 20 percent of acephate raw powder, 1 to 10 percent of a surface active agent, and the balance is a solvent.

Description

technical field [0001] The invention belongs to the technical field of tree pest control, and in particular relates to a dry-injected insecticide for preventing and treating sycamore syringa stinkbug, a preparation method and application thereof. Background technique [0002] Corythucha ciliata (Say) is an invasive pest introduced into my country in recent years, and it is an important piercing-sucking pest on the Platanus genus Platanus in the family Platanaceae. In less than 10 years, it has spread rapidly throughout most of the Yangtze River Basin, and has spread to Shaanxi, Shandong and Beijing in the north, with an obvious trend of continuing to spread north and south. The insect clusters as adults and nymphs on the back of the host leaves to pierce and suck the juice, initially causing yellow and white spots and leaves chlorosis, and in severe cases, the leaves start to dry from the veins to the whole leaves chlorosis, black and necrosis, resulting in early leaf fall a...

AI Technical Summary

Problems solved by technology

However, because trunk injection is a new technology for fruit trees and forest management, it is extremely difficult to buy special medicines on the market. People usually use existing spray agents to dilute them and inject them into trunks. Decomposition or hydrolysis failure phenomenon

Therefore, in the prior art, there is still a lack of an effective solution for the prevention and treatment of the sycamore bug problem.
