Embodiment 1

[0034] The preparation process of chlorfenapyr water-soluble granules:

[0035] ①Material preparation: Prepare the raw materials according to the following formula:

[0036] Chlorfenapyr: 1%;

[0037] King phenol polyoxyethylene ether: 3%;

[0038] β-cyclodextrin: 1%;

[0039] Sodium dodecylbenzenesulfonate: 5%;

[0040] Dispersant NNO: 4%;

[0041] Sodium Benzoate: 1%;

[0042] Sodium bicarbonate: 47%;

[0043] Anhydrous citric acid: 38%;

[0044] ②Mix chlorfenapyr, β-cyclodextrin and sodium dodecylbenzene sulfonate in water at 55°C at 420 kg / cm 2 stirring and homogenizing under high pressure, and spray-drying the above-mentioned liquid mixture after homogenization to make a compound parent drug;

[0045] ③ After thermally dissolving vinylphenol polyoxyethylene ether, mix it with dispersant NNO, sodium benzoate, sodium bicarbonate, anhydrous citric acid and compound master drug at 45°C, and then mix it at 6 kg / cm 2 Stir and knead evenly under pressure to obtain a dou...

Embodiment 2

[0052] Preparation process is with embodiment 1, and used raw material formula is:

[0053] Chlorfenapyr: 10%;

[0054] Octylphenol ethoxylate: 6%;

[0055]Benzylphenol polyoxyethylene ether: 1%;

[0056] Sodium lignosulfonate: 3%;

Abstract

The invention provides a water soluble granule of chlorfenapyr. It is made from (by wt%) chlorfenapyr 0.5-50%, emulsifier 1-30%, dispersing agent 1-10%, wetting agent 1-5%, binder 2-4%, stabilizer 1-3% and the rest is filling material. The invention comprises no or small toxic and inflammable aromatic hydrocarbon solvent, therefore the risk of burning and exploding during manufacture, storage and transportation can be reduced. Its advantages include no poison and pollution, no unpleasant odor, low eye irritation, higher safety for producers, transporters and users.

Description

technical field [0001] The invention relates to a new dosage form of insecticide, in particular to a water-soluble granule containing chlorfenapyr and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of environmental protection and the emphasis on the ecological environment by governments of various countries, people are interested in high-efficiency, low-toxicity, low-residue, and pollution-free environmentally friendly biological pesticides and chemical pesticides that are suitable for the prevention and control of crop diseases and insect pests and pollution-free production. The need is growing. [0003] Chlorfenapyr is a pyrrole-type insecticide and acaricide developed by American Cyanamid Company. The chemical name is 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole -3-Nitril, also known as Qujin, Chlorfenapyr, Pyrrolamine, AC303630, etc. The drug has contact killing and stomach poisoning effects....
