A topical insecticide is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. In one preferred embodiment of the invention, the active ingredient of the insecticide formulation is an amine derivative, having a nitro-methylene group, a nitroamino group or a cyanoamino group, which can be formulated to have low toxicity and excellent insecticidal activity. One particularly suitable insecticide is 1-{(tetrahydro-3-furanyl)methyl}-2-nitro-3-methylguanidine (dinotefuran), an aldulticide that will kill adult fleas combined with pyriproxyfen.

The invention discloses a microemulsion pesticide. The microemulsion pesticide consists of the following ingredients in percentage by weight: 2.2-10% of active pharmaceutical ingredients, 2.5-20% of cyclohexanone, 2-10% of polyoxyethylene nonyl phenyl ether, 0.5-5% of agricultural emulsion No. 500, 2-10% of agricultural emulsion No. 602 and the balance of water, wherein the active pharmaceutical ingredients comprise one or two of beta-cypermethrin, iambda-cyhalothrin, cyfluthrin, methomyl, carbosulfan, pyriproxyfen, fluacrypyrim, diafenthiuron, hexaflumuron, phoxim, abamectin and acetamiprid. The microemulsion pesticide has the advantages of wide application scope, stable formulation and simple formula, and is convenient to operate.

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.

New pesticidal compositions comprising pyriproxyfen and methyl esters of C16-C18 fatty acids and having low volatile organic compound (VOC) content are provided. Methods of use and ready-to-use products are also provided.

A pyriproxyfen as insecticide is prepared from 4-hydroxydiphenyl ether, epoxy propane and 2-chloropyridine through dissolving 4-hydroxydiphenyl ether in alcohol, reacting on expoxy propane at 0-90 deg.C for 2-24 hr under existance of sodium hydroxide to obtain the intermediate, dissolving it in toluene, heating to 30-80 deg.C, slowly dropping 2-chloropyridine in it while reacting at 10-110 deg.C for 2-24 hr under existance of botassium hydroxide, distilling to remove toluene and refining.

The invention discloses an efficient insecticidal composition containing spiromesifen. The efficient insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from spiromesifen; the active ingredient B is selected from any one of the following compounds: pymetrozine, pyriproxyfen and dicyclanil; the weight ratio of the active ingredient A to the active ingredient B is (1:60)-(70:1). The composition disclosed by the invention has a synergistic effect on various pests generating hazards to agricultural production and is capable of reducing the pesticide dosage, the pesticide residue on crops and environment pollution, safe to human and livestock, good in environment compatibility and not easy to cause pest resistance to pesticides.
