Problems solved by technology

However, due to problems such as poor stability and short residual effect, it is necessary to solve this problem by slow-release granules
However, the existing slow-release granule preparation technology has the disadvantage of low bentonite pesticide loading rate, and it is difficult to realize the controlled release of carbosulfan, making it consistent with the occurrence of diseases and insect pests, so as to achieve safe, reasonable, economical and effective use purpose of pesticides
[0005] There is no report about the sustained-release granules of carbosulfan

Embodiment 1

[0019] Embodiment 1: 1% Carbosulfan Sustained Release Granules

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

Embodiment 2

[0021] Embodiment 2: 30% carbosulfan sustained-release granules

[0022] Mix 30kg carbofuran propylsulfide, 10kg epoxy linseed oil, 55kg carboxylated polyacrylate, 5kg alkylphenol polyoxyethylene ether, heat and melt to mix, granulate, cool and solidify to obtain 30% carbosulfan propylsulfide Sustained-release granules.

Embodiment 3

[0023] Embodiment 3: 10% carbosulfan sustained-release granules

[0024] After mixing 10kg carbofuran propylsulfide and 3kg epichlorohydrin evenly, spray it on 85kg kaolin and stir it evenly, then let it stand for 1-2 hours; after heating and melting 2kg liquid paraffin, spray it on the surface of the carrier and wrap it Get up and get 10% carbosulfan extended-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...
