Problems solved by technology

The company's researchers have found through long-term experiments in the field of pesticide compounding that the combination of the new quinazoline insecticide pyrifluquinazon and seven neonicotinoid insecticides has obvious synergistic effect and can effectively solve the above problems. Alkaline insecticides currently encounter problems such as resistance and environment in the market, and so far, no relevant studies and reports have been found that the combination of these two pesticide ingredients will have a synergistic effect

Embodiment 1

[0046] Embodiment 1: the processing and embodiment of quinazoline insecticide pyrifluquinazon and dinotefuran suspension concentrate

[0047] Pyrifluquinazon 3g, dinotefuran 47g, sodium lignosulfonate 13g, ethylene glycol 5g, 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 dinotefuran, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameters are all below 5mm, and the suspension preparation of the insecticidal composition containing pyrifluquinazon and dinotefuran described in the present invention is prepared.

[0048] Pyrifluquinazon 6g, dinotefuran 9g, sodium lignosulfonate 5g, ethylene glycol 3g, xanthan gum 7g, silicone oil 1g, make up the remaining water to 100g, mix other additives, mix evenly by high-speed shearing, add pyrifluquinazon and dinotefuran, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameters are all...

Embodiment 2

[0050] Embodiment 2: the processing and embodiment of pyrifluquinazon and acetamiprid aqueous emulsion

[0051] Pyrifluquinazon 6g, acetamiprid 14g, polyoxyethylene fatty alcohol ether 6g, methylene chloride 5g, sodium citrate 4g, ethylene glycol 3g, silicone oil 1g, xanthan gum 8g, water to make up to 100g. Add the original drug pyrifluquinazon and acetamiprid, 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 acetamiprid is prepared.

Embodiment 3

[0052] Embodiment 3: the processing and embodiment of pyrifluquinazon and clothianidin water-dispersible granule

[0053] Pyrifluquinazon 4g, clothianidin 46g, sodium lignosulfonate 12g, saponin powder 5g, citric acid 4g, white carbon black 29g. Mix pyrifluquinazon, clothianidin, dispersant, wetting agent, disintegrant and filler evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving After sampling and analysis, the water-dispersible granules of the insecticidal composition containing pyrifluquinazon and clothianidin according to the present invention were obtained.

Abstract

The invention relates to a pesticide composition compounded with part of nicotine compounds in the field of pesticide compounding. The active components of the pesticide composition are novel quinazoline pesticide pyrifluquinazon and part of the nicotine compound pesticides, the weight percentage ratio of the two active components is 1 to 90:90 to 1, preferably 1 to 50:60 to 5, the total mass percentage content of the active components in the pesticide composition is 1 to 90 percent, preferably 5 to 65 percent, the balance is acceptable auxiliary components allowed to be used in pesticides, and a known method is used for preparing the pesticide composition into emulsion in water, soluble concentrate, microcapsule suspension, microemulsion, emulsifiable concentrate, suspension, wettable powder, aqueous solution and water-dispersible granules. The pesticide composition with the novel quinazoline pesticide and the nicotine compound pesticides as the active components is mainly used for controlling pests on citrus trees, other fruit trees, vegetables and tea leaves.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition compounded in pairs with novel quinazoline insecticide pyrifluquinazon and seven kinds of nicotinic 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 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. The chemical structural formula of novel quinazoline insecticide pyrifluquinazon is: [0003] [0004] Several nicotinic compounds imidacloprid, acetamiprid, thiamethoxam, nitenpyram, thiacl...
