Problems solved by technology

However, due to the strong volatility of the active ingredients of allyl isothiocyanate and glutaraldehyde, it is easy to be affected by environmental conditions and cause sudden release, and the duration of effect is short, which makes it difficult for existing products to achieve long-term control of diseases and insect pests and reduce drug use. times, the purpose of reducing the cost of medication

[0030] The preparation method of the storage disease and insect pest control slow release granule of the present invention, it comprises the following steps:

[0031] A, according to the weight percentage of granular inert carrier kaolin is 55%, the weight percentage of allyl isothiocyanate is 20%, the weight percentage of glutaraldehyde is 10%, stabilizer 2,6-di-tert-butyl- The weight percentage of 4-methylphenol is 5%, and the weight percentage of coating agent polyethylene glycol is 10% to prepare raw material granular inert carrier, allyl isothiocyanate, glutaraldehyde, stabilizer and coating agent , and uniformly mix allyl isothiocyanate, glutaraldehyde and stabilizer therein to obtain active ingredients;

[0032] B. Spray the active ingredient on the granular inert carrier and stir evenly. The method of spraying the active ingredient is to spray the active ingredient on the granular inert carrier by disc spray method or compressed spray method, and then let it stand for ...

Embodiment 1

[0037] The preparation method of the storage pest control slow-release granule of the present invention comprises the following steps:

[0038] First mix 10g of glutaraldehyde, 5g of allyl isothiocyanate, and 0.2g of stabilizer 2,6-di-tert-butyl-4-methylphenol to obtain active ingredients, and spray the active ingredients evenly on the 182.8 g of granular inert carrier clay with an average particle size of 2 mm, stirred while spraying, and allowed to stand for 1 hour after stirring evenly. Heat and melt about 2 g of the coating agent polyethylene glycol 2000, and use the same method to evenly spray the coating agent polyethylene glycol 2000 on the granular inert carrier that has absorbed the active ingredient, stir while spraying, and after stirring evenly, you can get The 200g slow-release granule product for preventing and controlling stored diseases and insect pests of the present invention contains 7.5% of active ingredients.

Abstract

The invention discloses a sustained-release granule for controlling storage diseases and insect pests. The sustained-release granule comprises a granular inert carrier. Effective components are adsorbed on the granular inert carrier and comprise allyl isothiocyanate, glutaraldehyde and a stabilizing agent. A film-coating agent coats the surface of the granular inert carrier; the weight percentageof the granular inert carrier is 55-96.9 percent; the weight percentage of the allyl isothiocyanate is 1-20 percent; the weight percentage of the glutaraldehyde is 1-10 percent; the weight percentageof the stabilizing agent is 0.1-5 percent; and the weight percentage of the film-coating agent is 1-10 percent. The invention aims to provide the sustained-release granule for controlling the storagediseases and insect pests and a preparation method thereof, wherein the sustained-release granule has favorable controlling effect for main storage insect pests and germs, can control the diseases and insect pests with long action, reduce the drug-applied times and the drug-applied cost, is safe and economic in various links of production, transportation, storage, application and the like, saves labor power and physical resources, cannot damage the environment and is green and safe.

Description

technical field [0001] The invention relates to a slow-release granule for controlling storage diseases and insect pests and a preparation method thereof. Background technique [0002] Storage pests and diseases pose serious hazards to the storage of grain, tobacco, feed, and traditional Chinese medicinal materials. At present, fumigants such as methyl bromide are mainly used to treat pests in my country. However, because methyl bromide destroys the ozone layer in the atmosphere and seriously endangers the living environment of human beings, China is signing the International Environmental Protection Convention "Montreal Protocol" promised that China must completely phase out methyl bromide before January 1, 2015. Unraveling the singularity of alternative technologies will require accelerating the development of more fumigants and other new methods of controlling diseases and pests. [0003] The main component of horseradish is allyl isothiocyanate (AITC), which is a colorle...
