Problems solved by technology

Our company's R&D personnel have also gone through long-term research in the field of pesticide compounding. During a large number of test screenings, they accidentally discovered that the new quinazoline insecticide pyrifluquinazon and four bishydrazide insecticides tebufenozide, formazan The combination of any one of oxyfenozide, chlorfenozide, and chlorfenozide has a good synergistic effect, which meets the actual production requirements in agriculture, and the insecticidal insecticide compounded with these two active ingredients The composition has not seen any published related reports or research so far

[0036] Embodiment 1: the processing and embodiment of quinazoline insecticide pyrifluquinazon and methoxyfenozide suspension concentrate

[0037] Pyrifluquinazon 3g, methoxyfenozide 50g, sodium lignosulfonate 12g, ethylene glycol 4g, xanthan gum 9g, silicone oil 1g, make up the remaining water to 100g, mix other additives, mix evenly by high-speed shearing, Add pyrifluquinazon and methoxyfenozide, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameter is all below 5mm, and the insecticidal composition containing pyrifluquinazon and methoxyfenozide described in the present invention is prepared. Suspension formulations.

[0038] Pyrifluquinazon 7g, methoxyfenozide 13g, sodium lignosulfonate 5g, ethylene glycol 3g, xanthan gum 6g, silicone oil 1g, make up the remaining water to 100g, mix other additives, mix evenly by high-speed shearing, Add pyrifluquinazon and methoxyfenozide, and grind the balls in a ball mill for 2 to 3 hours, so that the particl...

Embodiment 2

[0040] Embodiment 2: Processing and embodiment of pyrifluquinazon and tebufenozide aqueous emulsion

[0041] Pyrifluquinazon 6g, tebufenozide 14g, polyoxyethylene fatty alcohol ether 5g, dichloromethane 4g, sodium citrate 4g, ethylene glycol 3g, silicone oil 1g, xanthan gum 7g, water to make up to 100g. Add the original drug pyrifluquinazon and tebufenozide, solvents, emulsifiers, and co-solvents together to dissolve into a uniform oil phase; mix some water, antifreeze, antimicrobial agents and other pesticide adjuvants 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 tebufenozide is prepared.

Abstract

The invention relates to a pesticidal composition in the field of pesticide compounding. Active ingredients, namely a novel quinazoline pesticide of pyrifluquinazon and a diacylhydrazine pesticide, are subjected to binary mixing, and the weight percentage ratio of the two active ingredients is 1:90-90:1, preferably (5-50):(60-5); and the pesticidal composition contains 1 to 90 mass percent of active ingredients, preferably 5 to 60 percent and the balance of auxiliary elements which are allowed to be used and acceptable in pesticides, and can be prepared into missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water, and microemulsion. After the novel quinazoline pesticide of pyrifluquinazon and the diacylhydrazine pesticide are subjected to binary mixing, the pesticidal composition has an obvious control effect on lepidoptera such as plutella xylostella, beet armyworm, prodenia litura, cotton bollworm, striped rice borer, mealybugs and the like, and sucking mouthparts pests of homoptera, such as plant hopper, aphid, mealywing, leafhopper and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, and relates to a dual compound insecticidal composition using pyrifluquinazon and bishydrazide pesticide compounds as active ingredients. 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 has high selectivity and is 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. The chemical structural formula of novel quinazoline insecticide pyrifluquinazon is: [0003] [0004] The bishydrazide insecticides involved in the present invention mainly include tebufenozide, methoxyfenozide, chlorfenozide...
