preparation example Construction

[0025] The preparation method of the emulsifiable granule of the present invention can be processed and formulated according to specific conditions. One method is: first mix the active ingredients, solvent, and liquid auxiliary components in the formula evenly, and then add the carrier and Mix other solid components in a uniform container to make it evenly adsorbed on the solid mixture, then pulverize it through an airflow mill, so that the particle size reaches 98% and pass through a 45μm sieve hole, and finally, add a certain amount of binder, After kneading and granulation; another method is: first mix the active ingredients, solvents and liquid additives in the formula, and then evenly adsorb on the components of the carrier and solid mixture that have been crushed to a particle size of 98% and pass through 45 μm. Then, add a certain amount of binder, knead and granulate. After the granulated product is dried in a fluidized bed, it is sieved, tested and packaged, and the e...

Abstract

The invention provides an emulsifiable granule containing an etofenprox composition and a preparation method thereof, and relates to an agricultural insecticide and a preparation method thereof. The emulsifiable granule comprises the following raw materials in weight percentage: 1%-15% of active constituents, 5%-30% of wetting dispersing agents, 0-10% of solvents, 5%-40% of adsorbents, 0-10% of binders and the balance of carriers. The preparation method comprises the following steps of: uniformly mixing the active constituents and the liquid assistant in the formula, and making the mixture adsorbed on the carriers, mixing the mixture with other solid constituents, pulverizing the mixture by using an airflow pulverizer so that the grain size of the mixture reaches 98%, sieving the mixture by using a sieve of 45 mum, and then kneading and pelleting. Alternatively, the method comprises the following steps of: uniformly mixing the active constituents, the solvents and the liquid assistant in the formula, making the mixture uniformly adsorbed on solid constituents and carriers pulverized to the grain size of 98% so as to pass through sieving holes of 45 mum, and then kneading and pelleting. The emulsifiable granule solves the problems of short effect taking time and environmental pollution of the traditional etofenprox and pymetrozine insecticide.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to an emulsifiable granule containing an etofenprox composition and a preparation method thereof. Background technique [0002] Long-term practical agricultural experience has shown that, on the one hand, repeated and exclusive application of an active compound to control pests will in many cases lead to resistance to the specific active compound and reduce the control effect of the agent. Often a combination of compounds with different mechanisms of action prolongs the life of the active ingredient. On the other hand, the insecticides currently used to protect plants generally use emulsifiable concentrates, suspension concentrates, and wettable powders. Although the emulsifiable concentrates have good drug effects, are relatively easy to prepare, and are convenient to use, the emulsifiable concentrates contain a large amount of organic solvents such as...
