Dinotefuran-containing liquid agent for being infused into tree trunks

Abstract

The invention discloses a dinotefuran-containing liquid agent for being infused into tree trunks.The obtained dinotefuran-containing liquid agent for being infused into tree trunks is prepared from, by mass, 2.0-10.0% of dinotefuran, 1-10% of emulsifier and the balance solvent, wherein the mass percentages of the raw materials sum up to 100%; or 1-20% of bactericide is added to the formula.The liquid agent is suitable for being infused into tree trunks to prevent and control multiple insects on economic trees, the insects on the economic trees are prevented and controlled, and meanwhile disease of the economic trees can be prevented and treated.The liquid agent has the advantages of being low in cost, high in prevention effect, wide in application scope and particularly suitable for preventing and controlling plant diseases and insect pests of dwarf economic trees such as apricot trees, apple trees and pear trees.

Description

technical field [0001] The invention belongs to the tree desiccant agent in the technical field of pesticides, in particular, it is a tree desiccant solution containing dinotefuran. Background technique [0002] By injecting medicine through the trunk, the medicine directly enters the tree body without contacting the surrounding environment, polluting the environment and causing harm to humans, animals and other beneficial organisms. It is a very ideal environmental compatibility and pollution-free pesticide application technology. The applicant applied for a Chinese invention patent "a kind of desiccating agent for trees" (patent number: ZL99111357.8) at the end of last century through a large amount of experimental research. Developed the first generation of dry liquid injection - 30% divos·oxyle insecticidal dry liquid injection, and obtained the national pesticide product registration (registration number: LS991064). Subsequently, in 2005, the applicant developed the se...

AI Technical Summary

Problems solved by technology

The main reason is that due to the artificial pruning and cultivation mode of dwarf economic trees, the tree type with low trunk branches and large number of side branches is formed. When the traditional dry injection liquid agent is used on dwarf economic trees, it is easy to have uneven conduction, and the control effect Poor, drug damage and other problems occur

Over the years, though many efforts have been made, it has not been possible to develop a liquid injection variety that can be used to control dwarf economic forest diseases and insect pests.

[0004] And with the gradual elimination of highly toxic pesticides such as dichlorvos and omethoate, the number of existing dry injection liquid agents is small and the variety is single. In addition, during the long-term use of imidacloprid and other agents, there are problems such as the risk of pesticide resistance of pests gradually , there is an urgent need to develop new types of dry injection liquids
