Embodiment 1

[0019] Example 1: 30% pyriproxyfen · spirodiclofen suspension concentrate.

[0020] 25% pyriproxyfen, 5% spirodiclofen, 15% alkylphenol polyoxyethylene ether, 15% sodium lauryl sulfate, 2% magnesium aluminum silicate, 2% glycerol, 0.1% silicone oil, deionized Water makes up 100%. Mix the above active ingredients, dispersant, wetting agent, thickener, antifreeze, defoamer and deionized water, disperse with high speed shearing, and sand mill in a sand mill to form a highly dispersed and stable The suspension system can be used to prepare 30% pyriproxyfen spirodiclofen suspension concentrate.

Embodiment 2

[0021] Example 2: 20% pyriproxyfen·spirofen-emulsion in water.

[0022] 16% pyriproxyfen, 4% spirodiclofen, 10% xylene, 5% cyclohexanone, 10% styrene phenol polyoxyethylene ether, 10% lignosulfonate, 1% sodium sorbate, 1% propylene glycol , deionized water make up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, dissolve the antifreeze in water to form a water phase, slowly add the oil phase to the water phase under the action of a shearing machine, and continue to shear for about In 30 minutes, a 20% pyriproxyfen-spirofen-in-water emulsion can be prepared.

Embodiment 3

[0023] Example 3: 40% pyriproxyfen·spirofen microemulsion.

[0024] 30% pyriproxyfen, 10% spirodiclofen, 20% cyclohexanone, 15% styrene phenol polyoxyethylene ether, 2% sodium citrate, 1% silicone, 2% doubling, 100% deionized water . Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, and synergist to mix evenly, and finally add deionized water, and stir well to obtain 40% pyriproxyfen spirodiclofen Microemulsion.

Abstract

The invention discloses an insecticide acaricide composition containing pyriproxyfen and spirodiclofen. The insecticide acaricide composition comprises a first active ingredient--pyriproxyfen, a second active ingredient--spirodiclofen and frequently used auxiliary ingredients, wherein a weight ratio of pyriproxyfen to spirodiclofen is 40: 1 to 1: 40. According to results of a great amount of indoor and outdoor experiments, the insecticide acaricide composition provided by the invention has an obvious synergistic interaction effect and a broadened insecticidal spectrum and can be used for preventing and treating a plurality of agricultural insects, like red spiders, leafhoppers, whiteflies, plant louse and scale insects; meanwhile, since the application amount of the pesticide is reduced, the residual quantity of the pesticide on crops is reduced, pollution to the environment is mitigated, and generation of pest resistance to the pesticide is delayed.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a pesticide composition with pyriproxyfen and spirodiclofen as active ingredients. Background technique [0002] Pyriproxyfen: a new type of insecticide that is a juvenile hormone analogue, and its mechanism of action is an inhibitor of chitin synthase. It has a good control effect on whitefly, scale insect, diamondback moth, beet armyworm, spodoptera litura, pear yellow psyllid, thrips, etc. At the same time, this product has a good control effect on flies, mosquitoes and other sanitary pests. [0003] Spirodiclofen: It is a spirocyclic tetronic acid acaricide, the mechanism of action is to inhibit the fat synthesis of mites, block the energy metabolism of mites, and cause the death of mites. It can be used to prevent and control harmful mites on fruit trees, eggplant, pepper, tomato and other Solanaceous crops. In addition, it also has a good control effect...
