Description

Botanical insecticidal composition for preventing and controlling peach aphids of peach trees
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a botanical insecticidal composition for preventing and controlling peach aphids.
Background
The green peach aphids are also called green peach aphids and myzus persicae. Is widely distributed and occurs all over the country. The plant is mainly a peach tree, and also is a plurality of fruit trees such as apricot, plum, cherry, pear, orange and the like and a plurality of plants of cruciferae. The peach aphid is one of main pests of peach trees and also transmits various viruses. The growth of young shoots and leaf backs of adults and nymphs are taken as harm, the damaged leaves shrink and curl, the growth of the young shoots is seriously influenced, fungi are bred in the later period of excreted honey-like mucus, mildew is formed, and the appearance quality of fruits is influenced.
The prevention and control of the green peach aphids in agricultural production mainly depends on chemical pesticides. The chemical agent can kill natural enemies of the green peach aphids, destroy ecological balance, seriously weaken natural control capability in fields and easily cause rampant of the green peach aphids while preventing and controlling the green peach aphids. The large amount of chemical agents causes the peach aphids to generate drug resistance, which makes the peach aphids difficult to control. Along with the improvement of people's health, food safety and environmental awareness, the development of pesticides is also shifted towards high efficiency, safety and low residue. There is a start to find highly active substances from natural products instead of traditional chemical pesticides. The reasonable mixing can not only improve the control effect of pesticides and reduce the dosage, but also effectively delay the development of the drug resistance of plant diseases and insect pests. Therefore, development of efficient, safe and low-residue natural product active substances for preventing and controlling the green peach aphids and a compound composition thereof are urgently needed.
D-limonene is a monocyclic monoterpene, exists in a large amount in citrus plants such as oranges, kumquats, lemons and grapefruits, and has been reported to be used for preventing and controlling plant diseases and insect pests such as bemisia tabaci, red spiders, anthracnose and powdery mildew.
Pentadecene phenolic acid is an active substance obtained from ginkgo fruit extract. The ginkgo nut is extracted to have insecticidal activity, and the tanning of proteins in the insect epidermis is influenced by inhibiting the activity of the aminopeptidase of the insect epidermis, so that the hardening and darkening of the insect epidermis are interfered; by inhibiting the activities of peroxidase, hydrogenoxidase, etc., the metabolism and development of insects are disturbed, and the insects are killed. The action mode is contact killing and stomach poisoning, and can effectively control the occurrence of aphids.
At present, reports of d-limonene and pentadecenoic acid compound used for preventing and controlling peach aphids of peach trees are not yet seen. Therefore, the development of an agricultural composition with d-limonene and pentadecene phenylphenol acid as active ingredients can improve the pesticide effect and reduce the pesticide dosage, and has important significance.
