Embodiment 1

[0017] The following substances are all percentages by weight: Fluoropyrfurone 5%, trifluoropyrimidine 5%, mesitylene 20%, N-methylpyrrolidone 10%, alkylaryl polyoxypropylene polyoxyethylene ether phosphate 5%, Calcium dodecylbenzenesulfonate 5%, brassinolide 0.02%, thioketone 2%, soybean oil supplemented to 100%. After stirring and dissolving the above-mentioned active ingredients with a solvent, then adding other additives, fully stirring and mixing uniformly, the 10% fluoropyrfurone·trifluoropyrim ultra-low volume liquid can be prepared.

[0018] This embodiment is used for preventing and treating citrus scale insects: 10% flurpirfurone trifluoropyrim ultra-low volume liquid is diluted with water by 35ga.i. / ha and sprayed, and the control effects of 7d and 14d after the medicine are respectively 95.34%, 95.34%. 91.87%; 20% flurpirfurone soluble solution is diluted with water at 50ga.i. / ha and sprayed, and the control effects of 7d and 14d after the drug are 83.47% and 74.32...

Embodiment 2

[0020] The following substances are all percentages by weight: Flupyrfurone 12%, trifluoropyrimidine 3%, sodium carboxymethylcellulose 3%, polycaprolactone 2%, solvent naphtha S-200 10%, dimethyl carbonate 10% %, castor oil polyoxyethylene ether 5%, sodium methylene bis-naphthalene sulfonate 3%, and deionized water to make up to 100%. Mix the above effective ingredients, polymer capsule wall materials, and solvents to dissolve them into a uniform oil phase. Under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifiers and dispersants, and then add citric acid to adjust the pH value to 6.5, the balance is supplemented with deionized water, and the two materials react at the oil-water interface to form a polymer capsule wall, and 15% fluropyrfurone-trifluoropyrim microcapsule suspension can be prepared.

Abstract

A disclosed insecticidal composition containing flupyradifurone and triflumezopyrim contains flupyradifurone, triflumezopyrim and commonly-used auxiliary ingredients, the weight ratio of flupyradifurone to triflumezopyrim is 20:1-1:20, the total weight percentage content of flupyradifurone and triflumezopyrim in the composition is 1%-85%, and the balance is acceptable auxiliary ingredients being allowed using in pesticides. The insecticidal composition possesses substantial cooperation synergic effect on multiple insects on crops, the controlling effect of the insecticidal composition is obviously better than an individually-used single agent, also pesticide usage amount is reduced, the residual quantity of the pesticide on crops is reduced, environment pollution is mitigated, generation of insect drug resistance is delayed, and pesticide service life is prolonged.

Description

technical field [0001] The present invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition with flurpirfurone and trifluoropyrimidine as active ingredients, which is mainly used in the prevention and treatment of Homoptera pests, tassels, etc. Pteroptera and Hemiptera pests. Background technique [0002] Flupyradifurone (Flupyradifurone), the chemical name is 4-[(6-chloro-3-pyridylmethyl)(2,2-difluoroethyl)amino]furan-2(5H)-one, a new type of smoke Alkaline insecticides act on the central nervous system of insects and are antagonists of insect nicotinic acetylcholine receptors. It is mainly effective against piercing-sucking mouthparts pests, harmless to bees, not subject to flowering application restrictions, and safe for crops. [0003] Triflumezopyrim, chemical name, 2,4-dioxo-1-(5-methylpyrimidine)-3-[3-trifluoromethylphenyl-2H-pyrido[1,2-α ]] Pyridine inner salt, a mesoionic insecticide, has a ...
