Abstract

The present invention relates to an insect disinfestation and yield increasing composition containing jasmonic acid and methyl jasmonate, wherein the effective active components are an active component A and an active component B, the active component A is selected from one of jasmonic acid and methyl jasmonate, and the active component B is any one compound selected from Bacillus thuringiensis, compound sodium nitrophenolate and compound potassium nitrophenolate. According to the oresent invention, the composition provides high activity for a variety of insect pests on a variety of crops, has characteristics of significant synergistic effect and insect disinfestation spectrum broadening, and can increase the effective absorption of crops on fertilizers, assist the good growth of inferior parts of crops, and regulate the water balance in crops, such that the metabolism system of crops can be activated, the cell growth of crops can be promoted, and the root activity can be enhanced.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal and yield-increasing composition containing jasmonic acid and methyl jasmonate to crops. [0002] technical background [0003] Jasmonic acid (JA for short) Chemical name: 3-oxo-2-2′-cis-pentenyl-cyclopentane-1-acetic acid, and methyl jasmonic acid (JA_Me for short), which is a type of fatty acid Derivatives, endogenous growth regulators found in higher plants. Jasmonic acid is a hormone that is ubiquitous in various plants and has a wide range of physiological functions. It is currently regarded as an endogenous growth regulator in higher plants. More importantly, it is a signal molecule that pathogens, elicitors and wounding induce the expression of plant defense genes, and it can also act as an elicitor. A large amount of genetic and molecular biological evidence has shown that JA, as an important endogenous signal molecule, participates in the d...
