Abstract

The invention relates to a pesticide preparation and a preparation method thereof, in particular to a novaluron EW (Emulsion in Water) and a preparation method thereof. The novaluron EW comprises the following components in parts by mass: 0.5-50 parts of novaluron technical, 1-15 parts of solvent, 1-15 parts of emulsifier, 0.1-10 parts of dispersing agent and thickener, 0.2-6 parts of co-emulsifier, 0.2-5 parts of antifreeze agent, 0.1-1.5 parts of defoaming agent and 0.1-3 parts of antimicrobial agent, a proper amount of pH regulator and the balance of deioned water. The novaluron EW has high control effect on cotton bollworm, Leguminivora glycinivorella, leaf roller, budworm, dendrolimus, white fly, thrip, rice stem borer and other insect pests harmful to various agricultural crops and garden crops, such as cotton, soybean, corn, fruit tree, rice, vegetables and the like. In the invention, no organic solvent or a little amount of organic solvent is used, thereby reducing preparation cost and use cost, lowering toxity to operators, storage and transport personnel and users during the processes of production, storage , transport and use. Therefore, the novaluron EW is an environmental-protection product with high safety.
