Embodiment 1

[0020] The following substances are all percentages by weight: Flupyrfuranone 2%, cyantraniliprole 8%, methylnaphthalene 20%, N-methylpyrrolidone 10%, phenethylphenol polyoxyethylene ether phosphate 5%, ten Calcium dialkylbenzene sulfonate 5%, brassinolide 0.02%, azone 2%, corn 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% flupyrfurone · cyantraniliprole ultra-low volume liquid can be prepared.

[0021] This embodiment is used to prevent and treat rice stem borer: 10% flupirfurone·chlorfluraniliprole ultra-low volume liquid is diluted and sprayed with water at 30g.a.i. / ha, and the control effects of 7d and 14d after the drug are respectively 93.89% , 91.64%; 200g / L flupyrfurone soluble agent is diluted with 50g.a.i. / ha and sprayed with water, and the control effects of 7d and 14d after the drug are 43.24% and 36.97% respectively; 20% chlorf...

Embodiment 2

[0023] The following substances are all percentages by weight: Flupyrfuranone 15%, Cyflunraniliprole 5%, Toluene Diisocyanate 20%, Solvent Naphtha S-200 10%, Dimethyl Carbonate 10%, Castor Oil Polyoxyethylene Ether 5% , Sodium methylene bis-naphthalene sulfonate 3%, 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 then 20% flupyrfurone · cyantraniliprole microcapsule suspension can be prepared.

Abstract

The invention discloses an insecticide composition containing flupyradifurone and cyhalodiamide. The insecticide composition containing flupyradifurone and cyhalodiamide comprises a first effective constituent of the flupyradifurone and a second effective constituent including the cyhalodiamide and common auxiliary elements, and the weight ratio of the flupyradifurone to the cyhalodiamide ranges from 40:1 to 1:40. A large number of interior and outdoor tests show that the insecticide composition has the obvious synergistic interaction effect, and the preventing and treating effect of the insecticide composition on multiple injurious insects is obviously superior to that when the single dosage is singly used; meanwhile, the using amount of the pesticide is reduced, the residue amount of the pesticide is reduced, pollution to the environment is reduced, generation of insect resistance to the pesticide is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition containing flupyrfurone and cyantraniliprole as active ingredients, which is applied to the control of pests on crops. Background technique [0002] Flupyradifurone is a new type of nicotinic insecticide, which acts on the central nervous system of insects and is an antagonist 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] Cyflunraniliprole is a new type of phthalamide insecticide. Its mechanism of action is to open the calcium ion channel by binding to the ryanodine receptor in the pest body, so that the calcium ion stored in the cell can be continuously released into the muscle. In the plasma, calcium ions combine with the matrix protein in the sarcoplasm, ca...
