Problems solved by technology

[0010] Based on the above technical background, in order to meet the actual production needs in agriculture and solve the problem that pests are prone to develop resistance to a single pesticide with a relatively single mechanism of action, in practical applications, it will not only improve the insecticidal efficiency, but also delay the development of pest resistance. produce, and can reduce the use of pesticides and the number of repeated medications, making the application of pesticides more efficient and environmentally friendly

Embodiment 1

[0044] Embodiment 1: the processing and embodiment of novel quinazoline insecticide pyrifluquinazon and emamectin benzoate suspension concentrate

[0045] Pyrifluquinazon 5g, emamectin benzoate 1g, sodium lignosulfonate 3g, ethylene glycol 2g, 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 emamectin benzoate, 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 emamectin benzoate of the present invention is prepared.

[0046] Pyrifluquinazon 15g, emamectin benzoate 2g, sodium lignosulfonate 6g, ethylene glycol 3g, 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 emamectin benzoate, and grind the balls in a ball mill for 2 to 3 hours, s...

Embodiment 2

[0048] Embodiment 2: the processing and embodiment of pyrifluquinazon and abamectin aqueous emulsion

[0049] Pyrifluquinazon 10g, abamectin 1g, polyoxyethylene fatty alcohol ether 4g, dichloromethane 3g, sodium citrate 4g, ethylene glycol 3g, silicone oil 1g, xanthan gum 5g, water to make up to 100g. Add the original drug pyrifluquinazon and abamectin, solvent, emulsifier, and co-solvent to dissolve into a uniform oil phase; mix some water, antifreeze, antimicrobial and other pesticide adjuvants together to form Uniform water phase; 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, Forms an oil-in-water emulsion. That is, the water emulsion of the insecticidal composition containing pyrifluquinazon and abamectin is prepared.

Embodiment 3

[0050] Embodiment 3: the processing and embodiment of pyrifluquinazon and emamectin emamectin saline dispersible granule

[0051] Pyrifluquinazon 2g, emamectin benzoate 10g, sodium lignosulfonate 6g, saponin powder 6g, citric acid 2g, white carbon black 74g. Mix pyrifluquinazon, emamectin emamectin, sodium lignosulfonate, saponin powder, citric acid and white carbon black evenly, pulverize with an ultra-fine jet mill, knead, and then add it to a fluidized bed granulation dryer for granulation , drying, sieving, and after sampling analysis, the water-dispersible granules of the insecticidal composition containing pyrifluquinazon and emamectin benzoate of the present invention are obtained.

Abstract

The present invention relates to an insecticidal composition, and belongs to the field of insecticidal compounding. The active ingredients include novel quinazoline insecticidal pyrifluquinazon and abamectin or emamectin benzoate. The weight ratio of the two active ingredients is 1-90:50-0.1, and preferably 5-50:20-0.1. The mass percentage of the total amount of active ingredients in the insecticidal composition is 1%-90%, preferably 1% -40%, and the rest is insecticide allowed and acceptable auxiliary components. The insecticidal composition can be prepared into water emulsion, micro-emulsion, missible oil, a suspending agent, wettable powder, granules, soluble liquid, water dispersible granule, and a microcapsule suspending agent by known methods. The insecticidal composition can be used to control insects of aphids, whiteflies, leafhoppers and planthoppers, is suitable for vegetables, ornamental plants, fruit trees, citrus, rice, cotton and multiple field crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing two active ingredients of novel quinazoline compound pyrifluquinazon and abamectin or emamectin benzoate. technical background [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 two macrolide insecticides involved in the present invention are emamectin benzoate and abamect...
