Abstract

Hostathion micro-emulsion, a kind of pesticide composition, is comprised of 5-25wt.% of hostathion,1-10wt.% of solvent,5-30wt.% emulsifying agent,0.5-5wt% stabilizing agent and residual water. And stabilizing agent is selected from at least one of the followings, ammonium acetate,ammonium sulphate,potassium dihydrogen phosphate(KDP),diammonium phosphate,carbamide,methylurea,ethylurea. It is advanced in its low production cost and being safe during the production, the storage and the use period. The stability of hostathion is obviously improved, especially in solving the sedimentation issue. The solvent is greatly reduced, so it is more economic to the resource and the environment.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a triazophos microemulsion and a preparation method thereof. Background technique [0002] Triazophos is a broad-spectrum insecticide with certain nematicide activity. This agent has contact killing and stomach poisoning effects, and has a certain infiltration effect. Its registered crops and control objects are mainly rice stem borer, Three stem borers. The dosage form is mainly emulsifiable concentrate, and the content is 20%, 30%, 40%. The triazophos produced by many manufacturers are all emulsifiable concentrate preparations. The emulsifiable concentrate formula needs to use a large amount of solvents such as toluene, xylene, methanol, etc., and the dosage is 40-70%. After a large amount of these organic solvents are used, they will seriously pollute water sources and destroy ecosystem. From the perspective of environmental protection and sustaina...
