Embodiment 1

[0023] Weigh 4 grams of pyrimectin, 1 gram of abamectin, 4 grams of calcium dodecylbenzenesulfonate, 3 grams of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total weight of 100 grams. The above raw materials are put into a mixing tank according to the conventional method for preparing cream and mixed to form a preparation of 5% pyrimefate-abamectin cream.

[0024] Indoor synergistic bioassay was carried out, the resistant diamondback moth was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the co-toxicity coefficient was calculated according to the Sun Yunpei method with the LC50 value:

Abstract

A synergistic composite insecticide for preventing and treating cabbage caterpillar and rice borer contains two primary active components including abamectin or methylamino abamectin benzoate, assistant and excipient.

Description

technical field [0001] The invention relates to an insecticidal composition and application thereof, in particular to a synergistic insecticidal composition containing pyrimectin and abamectin or emamectin benzoate and application thereof. technical background [0002] Pyrimiden (test code: NA83, common name: fluacrypyrim, trade name: Titaron) is the first methoxyacrylate acaricide developed by BASF and Nippon Soda. Pyrimiden was randomly synthesized and optimized on the basis of methoxyacrylate fungicides. The chemical name of pyrimidin is methyl(E)-2-{a-[2-isopropoxy-6-(trifluoromethyl)pyrimidin-4-yloxy]-o-tolyl}-3- Methyl methoxyacrylate. [0003] Pyrimiden is a mitochondrial respiration inhibitor that inhibits mitochondrial respiration by electron transfer between cytochrome b and c1. Mitochondria outside the nucleus mainly provide energy (ATP) for cells through respiration. If mitochondrial respiration is blocked and ATP cannot be produced, cells will die. [0004] ...
