Botanical insecticide composition and application thereof

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a botanical insecticidal protectant and application thereof. The invention provides a nimbin and lufenuron complex botanical insecticidal protectant and application thereof. The complex insecticidal composition obviously enhances the insecticidal effect, and different action modes thereof are beneficial to postpone generation of drug resistance of pests and reduce pesticide residue, thus ensuring that the complex insecticidal composition is an environment-friendly insecticide. The composition is mainly used for controlling pests of lepidoptera and coleoptera, and can be also used for controlling multiple mites.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition and its application. Background technique [0002] Azadirachtin, English name: azadirachtin. [0003] The compound is a natural botanical insecticide extracted from neem seeds, which has strong contact and stomach poisoning effects on insects, especially cabbage butterfly larvae, diamondback moths and aphids. Early studies have shown that the mechanism of action of azadirachtin directly or indirectly produces an antifeedant effect by destroying the chemosensory organs of insect mouthparts; through the effect on midgut digestive enzymes, the nutritional conversion of food is insufficient, which affects the vitality of insects. High doses of azadirachtin can directly kill insects, while low doses can cause permanent larvae, or deformed pupae, adults, etc. By inhibiting the synthesis and release of prothymostimulating hormone (PTrH) by brain ...
