Problems solved by technology

The induction of insect resistance in plants begins with the recognition of resistance elicitors. By activating various insect resistance signaling pathways in plants, plants are induced to produce a large amount of insect resistance signal substances such as jasmonic acid. Under the stimulation of these substances, plants On the one hand, induce plants to accumulate more defensive compounds that can directly act on pests, such as polyphenol oxidase, protease inhibitors, etc., which affect the feeding behavior of pests, resulting in malnutrition, low fecundity, and high mortality

Abstract

The invention provides an inducible insect-resistant agent for preventing inchworm pests of tea trees and belongs to the technical field of pest green prevention of tea trees. The inducible insect-resistant agent is prepared from, by weight, 0.5-200 parts of cis-3-hexenylacetate, 1-20 parts of cis-3-hexenol, 1.5-100 parts of anhydrous ethanol, 0.1-10 parts of tween-20, 100-800 parts of a phosphate buffer, 0.001-0.02 part of 2,6-butylated hydroxytoluene and 0.001-0.02 part of 2-hydroxy-4-methoxybenzophenone. Main components used in the agent come from plant volatiles, insect resistance is conducted by improving induced resistance of plants, and the inducible insect-resistant agent has the advantages that the agent is efficient, completely environmentally friendly and harmless to human beings and livestock and insecticide resistance is not likely to occur, is a safe and efficient pest prevention insecticide and particularly suitable for tea tree pollution-free production and has broad economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of green prevention and control of tea tree pests, and in particular relates to an induced insect-resistant agent for preventing and controlling tea tree geometrid pests. Background technique [0002] Inchworm pests (such as tea inchworm, silver inchworm, tung leaf inchworm, etc.) are important pests of tea trees. They seriously damage tea trees all the year round. They mainly use larvae to feed on the young and adult leaves of tea trees and harm tea trees. They often cause baldness of tea bushes, affecting tea yield, Quality; when it is serious, the tea garden seems to be on fire, causing great losses. At present, tea geometrids are mainly controlled by chemical pesticides, botanical pesticides or pathogenic virus preparations. However, repeated use of chemical pesticides not only easily causes pesticide residues in tea leaves and pollutes the environment, kills a large number of natural enemies, thereby d...
