Embodiment 1

[0019] Example 1: 30% etoxazole·spirotetramat suspension concentrate.

[0020] Etoxazole 5%, spirotetramat 25%, fatty acid polyoxyethylene ester 15%, sodium lauryl sulfate 10%, methyl cellulose 2%, glycerin 2%, silicone oil 0.1%, deionized water Make 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 30% etoxazole · spirotetramat suspension concentrate can be prepared.

Embodiment 2

[0021] Example 2: 40% etoxazole·spirotetramat emulsion in water.

[0022] 10% etoxazole, 30% spirotetramat, 25% mineral spirits, 10% polyoxyethylene fatty alcohol ether, 5% polycarboxylate, 1% sodium sorbate, 1% glycerin, deionized water to supplement 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 40% etoxazole-spirotetramat aqueous emulsion can be prepared.

Embodiment 3

[0023] Example 3: 25% etoxazole·spirotetramat microemulsion.

[0024] Etoxazole 20%, spirotetramat 5%, mineral spirits 20%, castor oil polyoxyethylene ether 15%, resorcinol 2%, silicone 1%, azone 2%, deionized water to make up 100% . Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, and synergist and mix evenly, and finally add deionized water and stir thoroughly to obtain 25% etoxazole · spirulina Ester microemulsion.

Abstract

The invention discloses an insect and mite killing composition containing etoxazole and spirotetramat. Effective components of the insect and mite killing composition are etoxazole and spirotetramat, wherein the weight ratio of etoxazole to spirotetramat is (30 to 1)-(1 to 30). A large quantity of indoor and outdoor experiments show that the insect and mite killing composition has an obvious synergistic interaction effect and can be used for preventing and controlling multiple insects, such as red spiders, aleyrodid, aphids and testas in agriculture; meanwhile, the use quantity of pesticides is reduced, so that the residual quantity of the pesticides on crops is reduced; therefore, the pollution to the environment is reduced, and the pesticide resistance of the insects is delayed.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal and acaricidal composition containing etoxazole and spirotetramat. Background technique [0002] Etoxazole belongs to diphenyloxazoline derivatives, and its mechanism of action is to inhibit the embryo formation of mite eggs and the moulting process from larvae to adults. It is effective for eggs and larvae, but not for adults. It is mainly used to control spider mites on apples and citrus. [0003] Spirotetramat belongs to tetronic acid compounds, and its mechanism of action is to inhibit the synthesis of lipids in insects, causing their poisoning and death. It can effectively control various piercing-sucking mouthparts pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects. [0004] The problem of pesticide resistance of agricultural pests is a global problem and has always been a key topic of concern to agricultural sci...
