A kind of plugging agent for preventing and controlling the pink-necked longhorn beetle and its preparation method and application

Abstract

The invention relates to a plugging agent used for preventing and controlling Aromia bungii, and a preparation method and applications thereof. The plugging agent comprises 800 to 1200g of a filling agent, 180 to 200ml of water, 15 to 21ml of a pesticide, 180 to 200ml of a humectant, and 10 to 30mg of a lithium-based grease. The preparation method is simple; prevention effect is excellent; and theplugging agent is capable of killing Aromia bungii and other trunk borers effectively.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a plugging agent for preventing and controlling the longhorn beetle and its preparation method and application. Background technique [0002] Peach trees are important fruit trees and ornamental tree species. Peach-necked longhorn is a destructive pest of peach trees. It eats branches, dry phloem and xylem with larvae, cuts off the tree's transport tissue, hinders nutrient and water transportation, and causes tree vigor. Weakness, dry branches, a large amount of sawdust-like insect droppings piled up outside the boreholes, glue flow often occurs in the damaged parts, the fruit yield and quality are greatly reduced, and when the damage is serious, the whole tree may even die. Great threat. In addition, the pink-necked longhorn beetle also harms apricot, plum, plum, cherry and other tree species. [0003] The newly hatched larvae of the pink-necked longhorn beetle eat under th...

AI Technical Summary

Problems solved by technology

The larvae hidden under the bark, phloem or xylem can be manually excavated or hooked out with a spiral steel wire, but due to the long and complicated worm-eaten path, it is difficult to clean up and the efficiency is low; natural enemies such as Beauveria bassiana and pathogenic nematodes can Insects have a certain control effect, but the production, transportation, preservation, reproduction, and release of natural enemies require harsh environmental conditions, which are technically difficult and inconvenient to apply; pouring high-concentration medicinal liquid or ointment into the boreholes is harmful to the roots and necks. Or the larvae harmed on the upright trunk have a certain control effect, but because peach trees are mostly in the shape of happy trees and the main branches are relatively flat, the larvae on these branches, especially the larvae harmed under the branches or under the inclined trunk, should be controlled. The medicine liquid and ointment are not easy to inject and easy to overflow, which affects the efficacy of the medicine. After the medicine is injected, it needs to be blocked with wet mud, which is time-consuming and laborious, and the prevention effect is not good.
