Aqueous emulsion 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 aqueous emulsion of the propylene glycol alginate and the nitenpyram comprises the ingredients by weight percent such as 10 percent of propylene glycol alginate, 5 percent of nitenpyram, 8 percent of fatty alcohol-polyoxyethylene ether, 5 percent of Tween 20, 6 percent of No. 603, 2 percent of propylene glycol and balance of water, the ingredients are placed into a high-shearing mixing kettle to be mixed according to a conventional aqueous agent preparation method to produce the aqueous emulsion with 10 percent of propylene glycol alginate and 5 percent of nitenpyram. Liquid medicine prepared by the aqueous emulsion is proved to be stable and homogenous in a cold storage test and in 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 aqueous emulsion also has a function on facilitating food refusal and sterility of an insect pest. After entering a body of the insect pest, the aqueous emulsion can destruct cell membranes and cellular organs on the wall of mid-intestines so as to prevent nerve conduction and to cause the damage.

Description

[0001] This patent application is an application for invention patent application (application number: 200810163726.1: 2008-12-31, invention creation name: insecticidal combination containing glycol esterolin). Technical field [0002] The present invention involves an agricultural pesticide combination, especially the pesticide combinations composed of alginate glycolin and hydhalidine or geritinin or methyl alfalinzozozoate. Background technique [0003] In recent years, thorns -sucking mouth pests have become popular or even explosive in large areas of north and south, especially rice live lice, whitefly, tea small green leaf cicada, nail jump, thistle wood lice, and cymbal worms are more crops.Wide range, even migration, causing secondary hazards, major losses caused by agricultural production. Due to the secretion of wax solution, the pest of the stabbing mouthpiece, there are many breeding algebraic algebra, the dangers are long and easy to resist chemical pesticides.The eff...
