Embodiment 1

[0024] Example 1 40% Pentamicloguanidine Azadirachtin EC (1:3)

[0025] 10% pentameticoguanidine, 30% azadirachtin, 8% N, N dimethylformamide, 10% N-methylpyrrolidone, 10% dimethylsulfide, 10% acetone, 4% ten Calcium dialkylbenzenesulfonate, 4% tristyrylphenol polyoxyethylene ether, 3% phenethylphenol formaldehyde resin polyoxyethylene ether, and the rest are supplemented with xylene. Prepare in a conventional manner.

Embodiment 2

[0026] Example 2 26% Pentamicloguanidine Azadirachtin Suspension Concentrate (25:1)

[0027] Pump 275 grams of deionized water into the stirring tank, pump 40 grams of dispersant NNO, 40 grams of dispersing agent MF, 50 grams of sodium lauryl sulfate, and 30 grams of ethylene glycol into the stirring tank, and then mix 250 grams of Put 1 g of pentametacoguanidine, 10 g of azadirachtin, and 5 g of kaolin into the shear tank in sequence, and shear for 30 minutes to make the materials evenly mixed. Turn on the circulating water, ball mill the material at a certain flow rate, control the temperature below 40 degrees, and pass the fineness through a 325-mesh sieve to obtain 26% Pentamicloguanidine·Azadirachtin Suspending Concentrate.

Embodiment 3

[0028] Example 3 60% Pentaclofen·Azadirachtin wettable powder (10:10)

[0029] With 300 grams of azadirachtin, 300 grams of pentametamiguanidine, 50 grams of dispersant MF, 40 grams of dispersant NNO, 30 grams of sodium lauryl sulfate, and 280 grams of pottery clay, stir them evenly, and process them by jet milling to obtain 60 % Pentamicloguanidine · Azadirachtin wettable powder.

Abstract

The invention discloses an insecticidal composition containing guadipyr and nimbin. Guadipyr and nimbin can be compounded and made into any dosage form acceptable in agriculture, such as missible oil, wettable powder, water dispersion particle, suspension agent, oil suspension agent, ultralow capacity liquid, electrostatic oil agent, and dry suspension agent. The composition can be used to control corresponding insects in agriculture, inhibits the generation of drug resistance of pests, reduces the using amount of pesticide, and is safe to the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and comprises a compounded insecticidal composition of pentetamicloguanidine and azadirachtin. Background technique [0002] Guadipyr is composed of neonicotinoids (represented by imidacloprid) and semicarbazones (represented by indoxacarb) by the research group of Professor Qin Zhaohai from China Agricultural University, using the method of molecular design and active substructure splicing. Representative) The active structure of the insecticide is cleverly assembled into the same molecule, and a new series of high-efficiency insecticide series compounds with the characteristics of neonicotinoids and sodium ion channel inhibitors have been obtained. It is an insecticide with independent intellectual property rights in my country. Pentetamiguanidine chemical name: 1-nitro-3-[(6-chloropyridin-3-yl)methyl]-4-pentamethylene aminoguanidine, pentetamicloguanidine has a unique mechanism of action, an...
