Embodiment 1

[0022] Weigh 80g of Lepimectin, 2g of diflubenzuron, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrate, and mix to form The main active ingredient is Lepimectin·diflubenzuron emulsifiable concentrate with a weight percentage of 82%.

Embodiment 2

[0024] Weigh 2g Lepimectin, 80g diflubenzuron, lignin 10g, sodium alkylnaphthalene sulfonate 2g, add to 100g with kaolin, mix the above raw materials in an ultrafine pulverizer, and form the main active ingredient weight percentage content of 82%. Lepimectin·diflubenzuron wettable powder.

Embodiment 3

[0026] Weigh 60g of Lepimectin, 2g of diflubenzuron, 8g of calcium dodecylbenzenesulfonate, 6g of phenylethylphenol polyoxyethylene ether, and add xylene to 100g, and put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrate. Lepimectin·diflubenzuron emulsifiable concentrate with a main active ingredient weight percentage of 62% is formed.

Abstract

The invention discloses a compound insecticidal composition containing Lepimectin and chlorbenzuron and application thereof. In the insecticidal composition, Lepimectin and chlorbenzuron are insecticidal active ingredients, wherein the weight ratio of the Lepimectin to chlorbenzuron is (0.1-80):(0.5-80). The insecticidal composition can generate a relatively strong synergistic effect, and can be used for overcoming and delaying the pest resistance to insecticide, realizing high insecticidal speed and long duration and reducing the application cost while the control effect is obviously better than that of single dosage. The compound insecticidal composition disclosed by the invention can control the lepidoptera pests on crops and particularly can be used for controlling helicoverpa armigera and borer while the effect is obviously better than that of single dosage.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides containing heterocyclic compounds, and specifically relates to a compound insecticidal composition. Background technique [0002] Lepimectin is a derivative of milbemycin (milbemycin) A3 / A4 discovered by Japan's Sankyo Company, and was registered for use in Japan in 2006. As a new type of insecticide, it is used in vegetables and fruits such as cabbage, tomato, citrus, strawberry and grape, mainly to control pests such as Lepidoptera and Hemiptera. The drug has the characteristics of high insecticidal activity, less dosage, safe for humans and animals, no environmental pollution, strong specificity, no harm to natural enemies, and not easy to produce resistance, etc. It can be used in rotation with abamectin insecticides, In case of abamectin resistance. Therefore, it is known as one of the most promising broad-spectrum, high-efficiency, new non-cross-resistance insecticides. Its mechan...
