Paste for preventing and curing stem borer

Abstract

The invention relates to a paste for preventing and curing stem borers, which is prepared by mixing the following raw materials based on the weigh ratio: 0.1-4 parts of botanical pesticide, 4-6 parts of kaolin, 0.5-1.5 parts of glycerol, 0.3-1 part of thickening agent and 10-13 parts of water. The paste has the advantages of certain stickiness, moderate mobility and long moisturizing period and pesticide effect period and has small possibility of drying and volatilizing. The paste is neutral and nontoxic, is safe to plants and does not pollute environment. The prevention and cure effect of the paste on Anoplophora glabripennis is improved by 64.4-69.8%, the prevention and cure effect on the Apriona swainsoni is improved by 50.6%, and the prevention and cure effect on small carpenter moths is improved by 13.8%. Meanwhile, the use amount and the loss amount of pesticides are lowered, thereby lightening environmental pollution.

Description

technical field [0001] The invention relates to a paste for preventing and controlling dry borers, belonging to the field of plant protection. Background technique [0002] Stem borer pests are destructive pests of forest trees, mainly including longhorn beetles, wood beetles, weevils, etc. They cause damage by eating larvae in the branches, forming complex borer passages, and affecting the channeling of nutrients and water in host plants , leading to weakening of the tree vigor, and in serious cases, the death of the whole plant, resulting in huge economic losses. Because borer pests live in seclusion for a long time, they are not easy to be found, are less affected by external environmental conditions, and their population density is relatively stable, so it is difficult to control them. [0003] At present, the method commonly used to control dry borers is mainly to inject high-concentration organophosphorus liquid from boreholes. Due to the complexity of dry borer pests...

Problems solved by technology

[0002] Stem borer pests are destructive pests of forest trees, mainly including longhorn beetles, wood beetles, weevils, etc., causing larvae to eat in the branches, forming complex borer passages, and affecting the channeling of nutrients and water in host plants , resulting in weakening of the tree vigor, and in severe cases, the death of the whole plant, resulting in huge economic losses

Due to the long-term hidden life of borer pests, it is difficult to be found, less affected by external environmental conditions, and the population density of insects is relatively stable, so it is difficult to control

[0003] At present, the method commonly used to control dry borers is mainly to inject high-concentration organophosphorus liquid from boreholes. Due to the complexity of dry borer pests, there are both upward and downward borers; There are many feces holes, and there are multiple defecation holes; this will easily cause the loss of liquid medicine, affect the efficacy of the medicine, pollute the environment, and be inconvenient to operate
