Example Embodiment

[0019] Example 1: 1% Carbosulfan Propionate Sustained-Release Granules

[0020] 1kg of carbosulfan propionate, 1kg of epoxidized soybean oil, 96kg of polyamide, and 2kg of lignosulfonate were mixed, heated and melted, granulated, cooled and solidified to obtain 1% carbosulfan slow-release granules.

Example Embodiment

[0021] Example 2: 30% Carbosulfan Propionate Sustained-Release Granules

[0022] 30kg of carbosulfan, 10kg of epoxy linseed oil, 55kg of carboxylated polyacrylate, and 5kg of alkylphenol polyoxyethylene ether were mixed, heated and melted, granulated, and cooled to solidify to obtain 30% carbosulfan. Sustained release granules.

Example Embodiment

[0023] Example 3: 10% Carbosulfan Propionate Sustained-Release Granules

[0024] After 10kg of carbosulfan and 3kg of epichlorohydrin are mixed evenly, spray it on 85kg of kaolin and stir it evenly, then let stand for 1-2 hours; after 2kg of liquid paraffin is heated and melted, sprayed onto the surface of the carrier and wrapped Get up to get 10% Carbosulfan Propionate Sustained-Release Granules.

Abstract

The invention discloses a benfuracarb sustained-release granule and a preparation method thereof. Benfuracarb is used as a pesticide effective active ingredient, one or a mixture of several of epoxy soybean oil, epoxy flaxseed oil and epoxy chloropropane is used as a stabilizer of the benfuracarb pesticide effective active ingredient, and the rest ingredients comprise a high molecular polymer, a carrier, a coating agent, cyclodextrin, a dispersant and a humectant. The content of the benfuracarb pesticide effective active ingredient is from 1% to 50%, the content of the stabilizer is from 1% to 10%, and the content of the rest ingredients is from 40% to 98%. The benfuracarb sustained-release granule has the advantages of high dug loading capacity, sustained release of pesticide active ingredients, capability of effectively preventing and controlling pests, great safety, great environment-friendliness and no residue. The benfuracarb sustained-release granule can be used for preventing and controlling rice lissorhoptrus oryzophilus, thrips, borer, cotton aphid, onion fly, plutella xylostella and the like, preventing and controlling underground pests as a soil treatment agent and preventing and controlling leaf pests, and can also be used for preventing and controlling pests related to sugarcane, corn and the like.

Description

technical field [0001] The invention relates to carbosulfan sustained-release granules and a preparation method thereof. Background technique [0002] Sustained-release granules are now widely used in the field of pesticide preparations, which can make the performance of the pesticide more stable and reduce the impact of environmental factors such as water and air; it can also greatly extend the duration of the same dose of pesticides; The frequency and amount of use can significantly reduce the possibility of residues and environmental pollution; in addition, it can also reduce the toxicity and injury of pesticides. [0003] At present, pesticide sustained-release granules are mainly composed of bentonite, organic modifier, pesticide active ingredient, inert filler and binder, and are prepared by the following methods: (1) take bentonite as the basic material, and use organic modifier to treat it Preparation of organic bentonite by modification; (2) Loading pesticide activ...
