Cream of propylene glycol alginate and nitenpyram

Abstract

The invention relates to an agricultural insecticidal composition, in particular to an insecticidal composition consisting of propylene glycol alginate and nitenpyram, abamectin or emamectin benzoate. The cream of the propylene glycol alginate and nitenpyram comprises the following raw materials by weight percent: 5 percent of propylene glycol alginate, 10 percent of nitenpyram, 8 percent of sodium sulfosuccinate alkylphenol polyoxyethylene ether, 6 percent of fatty alcohol-polyoxyethylene ether and balance of dimethylbenzene, and the raw materials are placed into a mixing kettle to be mixed according to a conventional method for preparing cream to produce cream with 5 percent of propylene glycol alginate and 10 percent of nitenpyram. Liquid medicine prepared by the cream is proved to be stable and homogenous in a cold storage test and a hot storage test, and a period of validity can reach more than three years. Besides a contact poison function and a stomach poison function of an ordinary chemical insecticide, the cream also has a function on facilitating food refusal and sterility of an insect pest. After entering a body of the insect pest, the cream can destruct cell membranes and cellular organs on the wall of mid-intestines so as to prevent nerve conduction and to cause the damage.
