Embodiment 1

[0021] Mix 5% active component (A) with 15% active component (B) and 15% emulsifier (available emulsifiers include agricultural milk series, etc.), appropriate amount of stabilizer, solubilizer and solvent xylene into cream.

Embodiment 2

[0023] 15% of active ingredient (A) and 25% of active ingredient (B) and 6% of 33# as emulsifier, agricultural milk 2000 series, 4% of NNO as dispersant, 0.2% of NNO as thickener Xanthan gum, 5% ethylene glycol or glycerol as an antifreeze agent, 0.5% stabilizer benzoic acid, and appropriate amount of defoamer n-butanol and water are uniformly pulverized under high-speed shearing to obtain a suspension.

Embodiment 3

[0025] 10% active ingredient (A) with 50% active ingredient (B), 2% sodium lauryl sulfate as wetting agent, 5% NNO as dispersant, 5% lignin as dispersant Calcium sulfonate and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Abstract

The invention belongs to a synergistic insecticidal composition, which is a mixture of compound (A) dinotefuran and compound (B) flubendiamide. The insecticidal composition of the present invention can be processed into emulsifiable concentrates, suspension concentrates, wettable powders, and water-dispersible granules. In the present invention, the weight ratio of compound (A) dinotefuran to compound (B) flubendiamide is 1-100:1-200. The insecticidal composition of the invention has high insecticidal efficiency and can effectively prevent and control various pests on various crops such as rice and vegetables. The control effect is significantly higher than that of compound (A) or compound (B) alone, and the dosage of each active substance is greatly reduced. The present invention not only has ecological significance, but also has important environmental protection significance.

Description

technical field [0001] The invention relates to an insecticidal composition with synergistic performance, in particular to a synergistic insecticidal composition containing dinotefuran and flubendiamide and its application. Background technique [0002] The English common name of the compound (A) in the present invention is: English name: dinotefuran. The Chinese common name is dinotefuran, and the CAS registration number is: 165252-70-0. The chemical name is 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine. Dinotefuran is a neonicotinoid insecticide with a broad insecticidal spectrum, excellent systemic penetration, and high insecticidal activity at a very low dose. It can control rice brown planthopper, white-backed planthopper, gray planthopper, black-tailed leafhopper, rice spider stinkbug, rice green stinkbug, red-bearded mirid bug, rice negative mixed insect, rice borer, Borer, three stem borer, rice leaf roller, rice locust, and control vegetables and fruit a...
