Abstract

The invention discloses an insecticidal solid micro-emulsifier containing triazophos, the components with the weight percent is as follows: 5 to 45 percent of triazophos, 5 to 25 percent of surfactant, 0 to 3 percent of binder, 0 to 5 percent of disintegrating agent and others a carrier. The invention also provides two preparation methods of the insecticidal solid micro-emulsifier, the first preparation method is that: 1) the raw materials are mixed with water evenly to prepare wet material; 2) the wet material is made into granules or pieces; 3) the granules or the pieces are dried; the second preparation method is that: 1) the raw materials are evenly mixed to form mixture; 2) the mixture is made into granules or pieces. The insecticidal solid micro-emulsifier of the invention not only can fully bring the biological activity of the effective contents into play and enhance the shelf life of the products, but also can prevent the pollution of chemical solvents to the environment since no chemical solvents are used.

Description

technical field [0001] The invention relates to the preparation principle and method of a brand-new pesticide dosage form-solid microemulsion, in particular to an insecticidal solid microemulsion containing triazophos and a preparation method thereof. Background technique [0002] As one of the 10 key varieties of triazoles determined by the National Development and Reform Commission and the Ministry of Agriculture to replace 5 highly toxic pesticides such as methamidophos, monocrotophos, methyl parathion, parathion, and omethoate Phosphorus is a broad-spectrum insecticide and acaricide, and also has a nematicide effect. It can be used to prevent and control lepidopteran pests and aphids on fruit trees, vegetables, and cereal crops. It has a huge market prospect. At present, triazophos has become my country's One of the leading varieties for controlling rice borer. According to statistics, as of February 2008, a total of 631 pesticide preparation products containing triazopho...
