[0031]The present invention also provides a method for preparing the above-mentioned emulsifiable granules, wherein the method comprises: taking the total weight of the emulsifiable granules as a basis, adding 0.1-60% by weight of emamectin benzoate , 0.1-20% by weight of the dispersant, 0.1-10% by weight of the wetting agent, 0.1-20% by weight of the emulsifier, 0.1-40% by weight of the adsorbent and 5-95% by weight of the filler mixed, through the air Crush and granulate. Wherein, the particle size of the raw material mixture is reduced to less than 10 μm by jet milling, and the particle size of the granulated particles is controlled within the range of 297-1680 μm. The dispersant, wetting agent, emulsifier and adsorbent used in the preparation process, as well as various other auxiliary agents used preferably, have been described in detail above, and will not be repeated here.

Abstract

The invention provides emulsifiable grains of emamectin benzoate and a preparation method thereof. Based on the total weight of the emulsifiable grains, the emulsifiable grains comprise 0.1 to 60 weight percent of emamectin benzoate, 0.1 to 20 weight percent of dispersant, 0.1 to 10 weight percent of wetting agent, 0.1 to 20 weight percent of emulsifying agent, 0.1 to 40 weight percent of adsorbent and 5 to 95 weight percent of filler. In the invention, the emamectin benzoate are made into emulsifiable grains, so the drawbacks of large dosage, low quick-action performance, short medicament effect duration and environmental pollution of the prior preparations of the emamectin benzoate are overcome, the dosage of the emamectin benzoate is reduced obviously, the quick-action performance and the medicament effect duration of the emamectin benzoate are improved, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to an emulsifiable granule of emamectin benzoate and a preparation method thereof. Background technique [0002] The chemical name of emamectin benzoate (Emamectin benzoate, emamectin salt) is: 4-methylamino-4-deoxyabamectin B 1a Benzoate, 4-methylamino-4-deoxyabamectin B 1b Benzoates. [0003] The structural formula is: [0004] [0005] The molecular formula is: C 56 h 81 NO 15 (B 1a ), C 55 h 79 NO 15 (B 1b ) [0006] The relative molecular weight is: 1008.26 (B 1a ), 994.23 (B 1b ) [0007] Emamectin benzoate is a fermented product of abamectin B 1 A new type of high-efficiency semi-synthetic macrolide antibiotic agricultural insecticide and acaricide has been synthesized. It has the characteristics of ultra-high efficiency, low toxicity and low residue. It can also pass through the plant skin and be absorbed by plants. It can effectively control Lepidoptera pes...
