Forest activity controlled-release coating agent and application thereof to pest control

Abstract

The invention relates to a forest activity controlled-release coating agent. The forest activity controlled-release coating agent is prepared from the following components in parts by weight: 5-15 parts of a polymer film-forming agent, 5-15 parts of water-soluble controlled-release resin, 5-10 parts of an emulsifying agent, 1-3 parts of a dispersing agent, 1-2 parts of a coloring indicator, 4-15 parts of an inert carrier and 40-79 parts of water; the above raw materials are mixed and ground to form suspension liquid having certain viscosity, which is the activity controlled-release coating agent. The invention also relates to application of the forest activity controlled-release coating agent to pest control; the forest activity controlled-release coating agent is mixed with an insecticide, a bactericide and the like, the mixture directly coats tree trunks to form long-acting controlled-release protective chemicals. The forest activity controlled-release coating agent has strong adhesiveness, has falling-off resistance, is breathable and permeable and has high stability, effective ingredients can be added in a targeted manner, and the defects that the traditional lime sulfur has short storage period, can lose efficiency easily, can cause diseases easily, and cannot be mixed with other pesticides are overcome; and besides, the operation is simple and easy, the labor intensity is low, the labor and time are saved, and the forest activity controlled-release coating agent can be applied and popularized conveniently.

Description

technical field [0001] The invention belongs to the field of prevention and control of forestry diseases and insect pests, and in particular relates to an active slow-release smear agent for tree trunks and its application in the prevention and control of diseases and insect pests. Background technique [0002] In the field of forestry, people whitewash the trunks in order to prevent insects and freezes, and attach a layer to the trunks to prevent rodents and herbivores, which can strongly stimulate the olfactory organs or taste organs of animals and make them refuse to eat. Substances such as forest trees are commonly referred to as forest protection agents. The existing forest protection agent mainly includes pomegranate mixture, but its storage period is short, it is easy to fail, and it is easy to cause phytotoxicity, so it cannot be mixed with other pesticides. The more advanced forest protection agents mainly include R-8 compound anti-feeding agent, FSB anti-feeding a...

AI Technical Summary

Problems solved by technology

The existing forest protection agents mainly include pomegranate mixture, but its storage period is short, it is prone to failure, and it is prone to phytotoxicity, so it cannot be mixed with other pesticides

The more advanced forest protection agents mainly include R-8 compound anti-feeding agent, FSB anti-feeding agent, Yunlin bird and mouse repellant and anti-gnawing agent, etc. These products generally have single protection objects, short protection period, and poor control effect , easy to fall off and other problems, although it has been widely used in tree trunk smearing since it came out, the effect is single and it has not been widely used.
