Problems solved by technology

However, if the above two kinds of pesticides are simply mixed in the field, not only is the pesticide wasted, but also the effect after application is poor. Therefore, it is necessary to propose a reasonable ratio of active ingredients and selection of adjuvants to obtain a pesticide that can be directly applied to field crops with a reasonable process.

Abstract

Disclosed is a composite Fipronil insecticide, which comprises 0.5-15 wt% of Fipronil, 0.1-10% of methylamino avermectin benzoate, and auxiliary agent. the insecticide can be prepared into missible oil, or wet powder, or suspending agent, or microemulsion. The insecticide can be used for controlling rice borer, Laodelphax srtiatellus, diamondback moth, Laphygma exigua Hubner, Heliothis assulta, and cotton worm.

Description

technical field [0001] The invention belongs to the technical field of pesticides and insecticides, and in particular relates to a compounded insecticide of fipronil. Background technique [0002] Fipronil (fipronil) is a phenylpyrazole insecticide with a wide insecticidal spectrum, which has contact killing, stomach poisoning and systemic effects, and is effective against a series of important pests such as Lepidoptera, flies and Coleoptera. Insect activity, long-lasting effect, can control rice thrips, rice borer, planthopper, diamondback moth, etc. However, fipronil has a slower effect and is more expensive. [0003] Amamectin benzoate (formamectin benzoate), the English common name is emanmectinbenzozte, the trade name is emamectin, the chemical name is 4″-deoxy-4″-table-methylamino-abamectin A mixture of Bla / Blb benzoates. Compared with abamectin, a relatively mature pesticide preparation, emamectin emamectin increases the insecticidal activity a...
