Embodiment 1

[0021] The weight ratio of components is:

[0022]

[0023] First, 2 parts of sodium naphthalenesulfonate formaldehyde condensate, 1.5 parts of sodium lauryl sulfate, 3 parts of sodium salt of alkylnaphthalenesulfonic acid condensation polymer, 3 parts of alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, Mix 20 parts of white carbon black and 50.5 parts of diatomaceous earth in a beaker, then add 5 parts of spirodiclofen, 5 parts of tebufenfen, 4 parts of agricultural milk 0201B, A mixture consisting of 3 parts of d-limonene and 3 parts of diethylene glycol dimethyl ether, mixed evenly, and pulverized by a jet mill to make the particle size reach 98% through 45 μm, and finally, add a certain amount of 2% ethanol aqueous solution Put it into the crushed material, knead and scraper granulate to obtain 10% spirodiclofen·tebufenpyrad emulsifiable granules.

Embodiment 2

[0025] The weight ratio of components is:

[0026]

[0027]

[0028] First, 1 part of carboxymethyl cellulose, 8 parts of bentonite, 1 part of sodium dodecylbenzenesulfonate, 3 parts of N-methyl-fatty acyl-sodium taurine, and 3 parts of alkylnaphthalenesulfonic acid polycondensate Sodium salt and 49 parts of activated clay were mixed in a beaker, and then at normal temperature and pressure, 7.5 parts of spirodiclofen, 7.5 parts of tebufenfen, 2 parts of castor oil polyoxyethylene ether, 2 parts of polyoxyethylene ether were added while stirring. A mixture consisting of 1 part of phenylethylphenol polyoxyethylene polyoxypropylene ether, 6 parts of Nongru 0201B, 5 parts of N-methylpyrrolidone, and 5 parts of xylene, mixed evenly, and pulverized by a jet mill to make the particle size reach 98 % pass through 45 μm, and finally, add a certain amount of distilled water to the above pulverized material, knead and scraper granulate to obtain 15% spirodiclofen·tebufenpyrad emuls...

Embodiment 3

[0030] The weight ratio of components is:

[0031]

[0032]

[0033] First, mix 20 parts of white carbon black and 36.5 parts of kaolin, and grind them through a jet mill to make the particle size reach 98% through 45 μm, and then add 10 parts of spirodiclofen while stirring under normal temperature and pressure conditions. , 10 parts of tebufenpyrad, 3 parts of sodium oleic acid methyl amino ethyl sulfonate, 5 parts of aralkylphenol polyoxyethylene ether phosphate, 5 parts of tristyrylphenol polyoxyethylene (n 20 ) ether phosphorylated triethanolamine salt, 1.5 parts of alkylphenol formaldehyde resin polyoxyethylene ether, 3 parts of d-limonene, 5 parts of N-methylpyrrolidone, and 1 part of polyethylene glycol 400. Mix evenly, and finally , adding a certain amount of distilled water to the crushed material, kneading and scraper granulation; 20% spirodiclofen·tebufenfen emulsifiable granules can be obtained.

Abstract

Disclosed is an emulsible granule containing spirodiclofen composition and a preparation method thereof. The emulsible granule is composed of components of, by weight, 1-60% of active components, 5-30% of wetting dispersants, 2-15% of solvents, 5-40% of adsorbents, 0-10% of binders and the balance carriers. The active components and liquid auxiliary components in the formula are evenly mixed, and the mixture is absorbed to the carriers; or the active components, the solvents and the liquid auxiliary components are evenly mixed and then mixed with other solid components, an airflow pulverizer is used for smashing the mixture so that granularity of 98% of the mixture reaches 45 mu m, and then the smashed mixture is subjected to kneading and granulation to prepare the emulsible granule. The emulsible granule is reasonable in the components, obvious in mite killing effects instead of simple adding of activity of the components, low in drug use cost, long in lasting period, safe in using, simple in preparation method, safe in storage and transportation, convenient to apply and environment-friendly and is an ideal variety of miticide.

Description

technical field [0001] The present invention relates to emulsifiable granules of spirofen-containing composition and its preparation method. Background technique [0002] There are many kinds of harmful mites in my country's agriculture, with mixed feeding habits, a wide range of hosts, and strong fecundity. Once the number of harmful mites increases explosively, it will cause great harm to crops. 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. [0003] Spirodiclofen has a brand-new structure and has contact killing effect. Its mechanism of action is to inhibit the fat synthesis in harmful mites and destroy the energy metabolism activities of mites. It has a wide acaricidal spectrum, long duration, low toxicity, low residue, good safety for humans, animals and ...
