Lethane of methylamino avermectin benzoate-Hexaflumuron

Abstract

An insecticide for the lepidopterous pests (beet no turnal moth, bollworm, plutella xylostella, etc) is prepared from methylamino abamectin benzoate, hexafluomuron, assistant and solvent through proportionally mixing. Its advantages are high effect, broad spectrum and no environmental pollution.

Description

1. Technical field [0001] The invention relates to an agricultural insecticide, in particular to a mixed insecticide compounded by emamectin benzoate and hexaflumuron. 2. Background technology [0002] Emamectin benzoate (emamectin benzoate) is a fermented product of avermectin B 1 (abamectin) hydroxyl derivatized 4″-deoxy4″-epi-methylamino-abamectin B 1 A mixture of benzoates (B 1a +B 1b ). Its mechanism of action is to hinder the insect's nerve transmission, causing the insect to be paralyzed and unable to move normally and die. It is a new type of biochemical pesticide. Emamectin benzoate has several times higher insecticidal activity against Lepidoptera than abamectin, and several times lower toxicity to warm-blooded animals than abamectin, and the active ingredient content used in the field is only abamectin 1 / 5 or lower of Vermectin. It is a high-efficiency, low-toxicity, broad-spectrum, and pollution-free insecticide. Several domestic enterprises have produced ...

Problems solved by technology

However, due to the slow insecticidal speed, it is not easy to be accepted by farmers, and it is easy to produce drug resistance if it is used alone for a long time in a large area.

[0004] In the Chinese patent CN-01123750, an insecticidal and acaricidal composition containing emamectin benzoate is disclosed. In the specification, it is pointed out that it can be compounded with dozens of compounds such as hexaflumuron, but It only points out that they can be used in combination, but does not point out the proportion and usage amount used together, and give specific examples and synergistic data
