Problems solved by technology

[0007] It can be seen that although the prior art involves the presence of immediate-release and sustained-release layers in granules, it does not pay attention to which active ingredients are used in each release layer, let alone the use of different adjuvants for different active ingredients.

Abstract

The invention relates to hygienic insecticidal granules and a preparation method thereof. The hygienic insecticidal granules are prepared from the following components in parts by weight: 0.1 to 10% of an active component A, 0.1 to 40% of an active component B, 0.2 to 20% of a solvent, 0.1 to 5.0% of an emulsifier, 0.1 to 5.0% of a dispersant, 0.1 to 5.0% of a slow-release film forming agent, 0.1 to 5.0% of a fast-release film forming agent, 0.1 to 10% of an adsorbent, and the balance of a porous carrier. The active component A is a slow-acting reagent, namely Bacillus thuringrensis israelesis Bti or pyriproxyfen; the active component B is selected from the group of fast-acting type neurotoxic reagents, namely fenthion, temephos, chlorpyrifos, pirimiphos-methyl, abamectin, ivermectin, and emamectin benzoate; the active component A is used for being adsorbed into the porous carrier which is wrapped with the active component B; the slow-release film forming agent is a hydrophobic high molecular polymer; the fast-release film forming agent is a water-soluble high-molecular polymer. The specific slow-release film forming agent and the fast-release film forming agent are selected, especially, the composite slow-release film forming agent, the composite fast-release film forming agent and corresponding insecticidal active components which are further compounded in a specific ratio are good in compatibility and have better fast-release and slow-release effects.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to a composition for hygienically killing mosquito and fly larvae and its application. Background technique [0002] Bacillus thuringiensis subsp. Israel (Bti) is a subspecies of Bacillus thuringiensis that has been studied earlier, with deeper research content and wider application range. It is widely used as a biological mosquitoicide to control the number of mosquitoes and flies. Bti is a Gram-positive spore-forming aerobic bacterium that produces a crystal protein that becomes a toxic protein when ingested by larvae. The toxic protein binds to special receptors on the cell wall of epithelial cells, causing cell membrane perforation , and finally lethal. In addition, it can also secrete thuringin, exotoxin, chitinase and other active ingredients. There are many sites of action, and it will not produce drug resistance. [0003] The juvenile hormone analog pyriproxyfen, its sp...
