Embodiment 1

[0025] Embodiment 1: (10% spirotetramat · efficient cyhalothrin aqueous emulsion)

[0026] Spirotetramat 5%, Beta-cyhalothrin 5%;

[0027] Xylene 6%, EO-PO block polymer 3%, polyvinyl alcohol 1%, ethylene glycol 0.5%, organic silicone 0.5%, water 89%.

[0028] Add spirotetramat, lambda-cyhalothrin, solvent, and emulsifier together to dissolve into a uniform oil phase, and mix water, antifreeze, defoamer, and thickener together to form a uniform water phase ; Under high-speed stirring, the water phase is added to the oil phase or the oil phase is added to the water phase, and the water emulsion product of the present invention is obtained after good dispersion.

[0029] This embodiment is used for preventing and treating capsicum whitefly. 10% spirotetramat · lambda-cyhalothrin aqueous emulsion was diluted and sprayed with water 1500 times, and the control effect 3 days after the drug was 93.5%, which was greater than the control effect of 5% spirotetramat 600 times 82.3, gre...

Embodiment 2

[0030] Embodiment 2: (22.5% spirotetramat · efficient cyhalothrin suspension concentrate)

[0031] Spirotetramat 20%, Beta-cyhalothrin 2.5%;

[0032] Sodium lignosulfonate 5%, ethylene glycol 4%, polyethylene glycol 2%, silicone oil 0.5%, deionized water to make up to 100%.

[0033] Mix spirotetramat, lambda-cyhalothrin, dispersant, wetting agent, thickener and water according to the proportion of the formula, and get a semi-finished product after sand milling or high-speed shearing. After analysis, add water to mix and filter evenly Obtain 22.5% spirotetramat · lambda-cyhalothrin suspension concentrate.

[0034] This embodiment is used for controlling apple aphids. 22.5% spirotetramat · lambda-cyhalothrin suspending agent was diluted and sprayed with water 3000 times, and the control effect 7 days after the drug was 98.2%, greater than 20% spirotetramat 2500 times 78.3%, greater than The control effect of 2.5% lambda-cyhalothrin is 1500 times 76.8%, and the application r...

Embodiment 3

[0035] Embodiment 3: (52.5% spirotetramat · efficient cyhalothrin microemulsion)

[0036] Spirotetramat 50%, Beta-cyhalothrin 2.5%;

[0037] Cyclohexanone 1%, styrylphenol polyoxyethylene ether 4%, bentonite 3%, organic silicone 0.5%, ethylene glycol 0.5%, deionized water to make up 100%.

[0038] This embodiment is used for preventing and treating pear psyllid, 52.5% spirotetramat · efficient cyhalothrin suspending agent is carried out 5000 times to add water dilution spray, the control effect of 3 days after the medicine is 94.4%, greater than 50% spirotetramat 4000 times of 85.2% control effect, greater than 2.5% lambda-cyhalothrin 1500 times of 72.7% control effect, the spraying results show that 52.5% spirotetramat · lambda-cyhalothrin microemulsion is better than spirotetramat, The synergistic effect of lambda-cyhalothrin alone was obvious.

Abstract

The invention discloses an insecticidal composition and applications thereof in controlling insects with a piercing-sucking mouthpart. The insecticidal composition comprises effective components and auxiliary components composed of spirotetramat and high efficient cyhalothrin, wherein the weight ratio of spirotetramat to high efficient cyhalothrin is 30:1 to 1:30. The insecticidal composition prepared by compounding spirotetramat and cyhalothrin has the advantages of high efficiency, low toxicity, and environment-friendliness, is benefit for treating the drug resistance of insects, inhibits the generation of drug resistance of insects, is used to control insects with a piercing-sucking mouthpart such as aphid, thrips, wood louse, rice planthopper, mealybug, aleyrodid, coccid, and the like, and has a very good control effect.

Description

technical field [0001] The invention belongs to a pesticide composition, in particular to an insecticidal composition containing spirotetramat and lambda-cyhalothrin. [0002] Background technique [0003] Spirotetramat is a new tetronic acid insecticide. Its mechanism of action is different from that of existing insecticides. It interferes with the fat biosynthesis of insects, leading to the death of larvae and reducing the reproductive capacity of adults. Spirotetramat has good systemic properties, can be transmitted to the top (upper) through the xylem and phloem of the plant, and can also be transmitted from the top to the bottom in the plant. It has a wide insecticidal spectrum and a long duration of action. It can control piercing-sucking mouthparts pests such as aphids and scale insects in various crops. Spirotetramat has an efficient and novel mechanism of action, and it will play an important role in the integrated pest management, especially the management of re...
