Problems solved by technology

Conventional insecticides have poor slow-release effect and rapid decomposition, and the conventional insecticides have a small bulk density. After application, they are easily washed away by sewer water, resulting in serious loss and easy to pollute downstream water bodies and the environment. Repeated application is often required to ensure the efficacy. To achieve the insecticidal effect, this leads to a large amount of insecticide application, low utilization rate, high cost of insecticide, and easy pollution to the environment

Embodiment 1

[0017] The present invention proposes a throwing-type insecticidal tablet, the raw materials of which include by weight: 2 parts of insecticide, 10 parts of sand, 15 parts of talcum powder, 5 parts of pregelatinized starch, and 1 part of sodium hydroxymethyl cellulose , 5 parts of microcrystalline cellulose, 0.5 part of preservative.

Embodiment 2

[0019] The present invention proposes a throwing-type insecticidal tablet, whose raw materials include by weight: 10 parts of insecticide, 95 parts of sand, 7 parts of talcum powder, 30 parts of pregelatinized starch, and 10 parts of sodium hydroxymethyl cellulose , 12 parts of microcrystalline cellulose, 1.5 parts of preservatives.

[0020] Among them, pregelatinized starch is prepared according to the following process: oxidized starch is mixed with deionized water to obtain starch milk, and then sodium hydroxide aqueous solution, vinyltriethoxysilane, sodium lignosulfonate, vinyl acetate, Acrylic acid and initiator are stirred and reacted, then chitosan, kaolin and polyethylene glycol are added, stirred, filtered, dried and pulverized to obtain pregelatinized starch.

Embodiment 3

[0022] The present invention proposes a throwing-type insecticidal tablet, whose raw materials include by weight: 5.5 parts of insecticide, 60 parts of sand, 11.5 parts of talcum powder, 18.5 parts of pregelatinized starch, and 6.8 parts of sodium hydroxymethyl cellulose , 9.6 parts of microcrystalline cellulose, 1 part of preservative, 0.2 part of tea saponin, 0.8 part of fulvic acid, 0.5 part of alopecia, 2 parts of vegetable oil.

[0023] Among them, pregelatinized starch is prepared according to the following process: mix 50 parts of oxidized starch with 16.5 parts of deionized water in parts by weight to obtain starch milk, then add 2 parts of sodium hydroxide aqueous solution, 1.2 parts of vinyltriethoxysilane , 0.8 parts of sodium lignosulfonate, 0.6 parts of vinyl acetate, 0.55 parts of acrylic acid and 0.2 parts of initiator, stirred and reacted at 68°C for 2.4h, then added 1.5 parts of chitosan, 0.8 parts of kaolin and 2 parts of polyethylene glycol Alcohol, stirred ...

Abstract

The invention discloses a casting insecticide tablet which comprises the following raw materials in parts by weight: 2-10 parts of an insecticide, 10-95 parts of sand, 7-15 parts of talcum powder, 5-30 parts of pregelatinized starch, 1-10 parts of sodium hydroxymethyl cellulose, 5-12 parts of microcrystalline cellulose and 0.5-1.5 parts of a preservative. The casting insecticide tablet has large capacity, is not easy to lose, has the advantages of small application amount, good sustained release effect, high utilization rate and long-lasting effect, effectively reduces the insecticidal cost, and simultaneously reduces the environmental pollution.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a throwing type insecticide tablet. Background technique [0002] Pests are easy to breed in the sewer, and insecticides are usually directly applied to the water body of the sewer to achieve the purpose of killing insects. Conventional insecticides have poor slow-release effect and rapid decomposition, and the conventional insecticides have a small bulk density. After application, they are easily washed away by sewer water flow, resulting in serious loss and easy to pollute downstream water bodies and the environment. Repeated application is often required to ensure the efficacy. To achieve the insecticidal effect, this leads to a large amount of insecticide application, low utilization rate, high cost of insecticide, and easy pollution to the environment. Therefore, it is an urgent problem to develop a kind of insecticide with small application amount, not easy to be lost...
