Embodiment 1

[0035] Embodiment 1: The processing and embodiment of novel quinazoline insecticide pyrifluquinazon and indoxacarb suspension

[0036] Pyrifluquinazon 3g, indoxacarb 50g, sodium lignosulfonate 13g, ethylene glycol 4g, xanthan gum 8g, silicone oil 1g, make up the remaining water to 100g, mix other additives, mix evenly by high-speed shearing, add pyrifluquinazon and the original drug of indoxacarb, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameters are all below 5 mm, and the suspension preparation of the insecticidal composition containing pyrifluquinazon and indoxacarb according to the present invention is prepared.

[0037] Pyrifluquinazon 5g, indoxacarb 13g, sodium lignosulfonate 5g, ethylene glycol 2.5g, xanthan gum 5g, silicone oil 1g, make up the remaining water to 100g, mix other additives, mix evenly by high-speed shearing, add The original medicines of pyrifluquinazon and indoxacarb are ground in a ball mill for 2 to 3 hours, so that t...

Embodiment 2

[0039] Embodiment 2: the processing and embodiment of pyrifluquinazon and indoxacarb aqueous emulsion

[0040] Pyrifluquinazon 6g, indoxacarb 14g, polyoxyethylene fatty alcohol ether 5g, dichloromethane 6g, sodium citrate 3g, ethylene glycol 3g, silicone oil 1g, xanthan gum 7g, water to make up to 100g. Add the original drug pyrifluquinazon and indoxacarb, solvents, emulsifiers, and co-solvents together to dissolve into a uniform oil phase; mix some water, antifreeze, antimicrobial agents and other pesticide additives together to form a uniform Add the oil phase to the water phase while stirring at high speed in the reactor, add water slowly until the phase inversion point is reached, turn on the shearing machine for high-speed shearing, and add the remaining water, shear for about half an hour, and form Oil-in-water emulsion. That is, an aqueous emulsion of an insecticidal composition containing pyrifluquinazon and indoxacarb is prepared.

Embodiment 3

[0041] Embodiment 3: The processing and embodiment of pyrifluquinazon and indoxacarb water-dispersible granule

[0042] Pyrifluquinazon 5g, indoxacarb 50g, sodium lignosulfonate 14g, saponin powder 7g, citric acid 3g, white carbon black 21g. Mix pyrifluquinazon, indoxacarb original drug, dispersant, wetting agent, disintegrant and filler evenly, pulverize with ultra-fine jet mill, knead, and then add to fluidized bed granulation dryer for granulation and drying 1. After sieving, the water-dispersible granules of the pesticidal composition containing pyrifluquinazon and indoxacarb of the present invention were obtained through sampling analysis.

Abstract

The invention relates to a pesticidal composition in the field of pesticide compounding, and discloses a binary mixed pesticidal composition containing active ingredients of a novel quinazoline pyrifluquinazon and indoxacarb. The weight percentage ratio of the novel quinazoline pyrifluquinazon to the indoxacarb is (1-90):(90-1), and (3-50):(60-5) preferably; the sum of the active ingredients is 1 to 90 mass percent of the pesticidal composition, and 5 to 60 percent preferably, and the balance is acceptable auxiliary elements allowed to be used in pesticides; and the pesticidal composition can be prepared into emulsion in water, microemulsion, an emulsifiable solution, a suspending agent, wettable powder and water dispersible granules. The pesticidal composition is mainly used for controlling injurious insects such as cnaphalocrocis medinalis, plutella xylostella, prodenia litura, cotton bollworm, beet armyworm and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition compounded with active ingredients in pyrifluquinazon and indoxacarb. Background technique [0002] Pyrifluquinazon is a new type of quinazoline insecticide newly developed by Japan Pesticide Company. Its mechanism of action is very novel. Its mechanism of action is to prevent pests from eating until they die slowly. It is highly selective and suitable for integrated pest control. Target biosafety, mainly used for the control of piercing-sucking mouthparts pests such as whitefly, broad bean aphid, aphid and scale insect on vegetables, fruit trees and tea, with excellent control effect. [0003] The chemical structural formula of novel quinazoline insecticide pyrifluquinazon is: [0004] [0005] Indoxacarb, 7-chloro-2,3,4a,5-tetrahydro-2-[methoxycarbonyl(4-trifluoromethoxyphenyl)carbamoyl]indeno[1,2-e] [1,3,4-]Methyl oxadiazine-4a-ca...
