Embodiment 1

[0015] Embodiment 1: add bentonite 71.5kg in high-speed mixer, start machine, then add calcium lignosulfonate 5kg, sodium dodecylbenzenesulfonate 1.5kg, add imidacloprid 2kg and buprofezin 20kg through 30 minutes again, through Take it out after 30 minutes, and then add it into an ultrafine pulverizer and pulverize it to a fineness of 325 meshes to obtain a 22% imidacloprid·buprofezin wettable powder. The above wettable powder was diluted 1000 times and sprayed, and the field efficacy test was carried out according to the method of Experimental Example 1. The results showed that the 1, 3, and 5-day control effects on rice planthoppers were 84%, 91%, and 96.5%, respectively.

Embodiment 2

[0016] Embodiment 2: add bentonite 65kg in high-speed mixer, start machine, then add calcium lignosulfonate 6kg, sodium dodecylbenzenesulfonate 1.5kg, add imidacloprid 2.5kg and buprofezin 25kg through 30 minutes again, through Take it out after 30 minutes, and then add it into an ultrafine pulverizer and pulverize it to a fineness of 325 meshes to obtain a 27.5% imidacloprid·buprofezin wettable powder. The above wettable powder was diluted 1000 times and sprayed. As a result, the 24, 48 and 72 hour control effects on Plutella xylostella were 52.5%, 65.3%, and 89%.

Embodiment 3

[0017] Embodiment 3: add diatomite 68kg in high-speed mixer, start machine, then add calcium lignosulfonate 5.5kg, sodium dodecylbenzenesulfonate 1.5kg, add imidacloprid 3kg and buprofezin 22kg through 30 minutes again , take it out after 30 minutes, and then add it into an ultrafine pulverizer and pulverize it to a fineness of 325 meshes to obtain 25% imidacloprid·buprofezin wettable powder. The above wettable powder was diluted 1000 times and sprayed, and the field efficacy test was carried out according to the method of Experimental Example 1. The results showed that the 1, 3, and 5-day control effects on rice planthoppers were 86.3%, 92.7%, and 97.4%.

Abstract

A kind of insecticide composite, mainly contains imidacloprid and buprofezin. It can be manufactured to wettable powder and miero emulsion type etc. The present invention has special preventing and killing effect to flying louse on rice. At the same time, it has better preventing and killing effect to thrips, cabbage caterpillar, diamond back moth, white loose, scale insect, peach fruit borer, red spider, bollworm, pink boll worm, etc. on vegetable, fruit tree, and cotton plant. The invention has high efficiency, low cost, little pollution.

Description

technical field [0001] The invention relates to a pesticide, in particular to an imidacloprid-buprofezin insecticide composition. Background technique [0002] Rice planthopper is an important pest of rice in my country, belonging to Homoptera, planthopper family. In the rice area, there are three main species, Laodelphax striatellus, Sogatella furcifera and Nilaparvata lugens, which mainly damage rice, but also damage wheat, corn, sugarcane, sorghum, millet and wild wild rice. Occurs in major rice areas across the country. Rice planthoppers transmit rice brown streak dwarf and stripe leaf blight, and are vector insects that transmit wheat bush dwarf and maize rough dwarf. Adults and nymphs gather at the base of the rice bushes, suck the juice of the stem and leaf tissue, consume the nutrients of the rice plant, make the grains not full, reduce the thousand-grain weight, and increase the shriveled grain; ", impeding the transportation of water and nutrients in the rice pl...
