Embodiment 1

[0031] Example 1 30% Bifenthrin·Fluflufen Aqueous Suspension Concentrate

[0032] The formula is: bifenthrin 20%, fluflufen 10%; dispersant styrene maleic anhydride polymer sodium salt 2% and polyoxyethylene-polyoxypropylene block copolymer 2%; wetting agent Sodium lauryl sulfate 1% and sodium alkylphenol polyoxyethylene ether sulfate 1%; antifoaming agent glycerin polyoxyethylene ether 0.1%; antifreeze agent propylene glycol 4%; preservative paraformaldehyde 0.1%; thickener yellow Raw gum 0.1%; water to make up 100%.

[0033] The preparation method is: put bifenthrin, fluflufen, dispersant, wetting agent, defoamer, antifreeze, preservative, thickener and water into a mixing tank, and stir for 30 minutes to mix the materials evenly , and then wet crush the material at 20-35°C, pass through a 100-mesh sieve after crushing, and obtain the finished water suspension agent after packaging.

Embodiment 2

[0034] Example 2 40% Bifenthrin·Fluflufen Aqueous Suspension Concentrate

[0035] The formula is: 30% bifenthrin, 10% fluflufen; dispersant styrene maleic anhydride acrylate polymer ammonium salt 2% and polyoxyethylene-polyoxypropylene block copolymer 4%; wetting Sodium lauryl sulfate 1% and sodium alkylphenol polyoxyethylene ether sulfate 2%; antifoaming agent high carbon alcohol fatty acid ester complex 0.1%; antifreeze agent propylene glycol 4%; preservative paraformaldehyde 0.1% ; thickener bentonite 0.1%; water to make up 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0036] Example 3 50% Bifenthrin Fluflufen Aqueous Suspension Concentrate

[0037] The formula is: 35% bifenthrin, 15% fluflufen; 3% dispersant sodium salt of styrene, acrylic acid and methacrylic acid copolymer and 3% polyoxyethylene-polyoxypropylene block copolymer; moisturizer Wet agent sodium lauryl sulfate 2% and alkylphenol polyoxyethylene ether sodium sulfate 2%; antifoaming agent glycerin polyoxyethylene ether 0.1%; antifreeze agent ethylene glycol 4%; preservative sodium benzoate 0.1%; Thickener magnesium aluminum silicate type SM gel 0.1%; water to make up 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses a water suspending agent containing bifenthrin and fluxapyroxad and a preparation method and application of the water suspending agent. The water suspending agent is prepared from the following components in percentage by weight: 20 to 60 percent of bifenthrin, 5 to 25 percent of fluxapyroxad, 2 to 10 percent of a dispersing agent, 1 to 10 percent of a wetting agent, 0.1 to1 percent of a defoaming agent, 3 to 8 percent of an anti-freezing agent, 0.1 to 1 percent of a preservative, 0.1 to 1 percent of a thickening agent and the balance of water. According to the invention, bifenthrin and fluxapyroxad are compounded and prepared into the water suspending agent, the water suspending agent has the advantages of remarkable pesticide effect, high suspension rate, safety,low toxicity and the like, the water suspending agent is used for killing pests such as grubs, cotton bollworms, cotton red spiders, thrips, wireworms, flea beetles and leaf beetles and has good prevention and treatment effects on various diseases such as potato black scurf, wheat sharp eyespot, rice sheath blight disease, sclerotinia sclerotiorum, wheat loose smut, wheat stink smut, corn leaf blight and corn head smut, and compared with a single agent of bifenthrin and fluxapyroxad, the water suspending agent has the advantage that the insecticidal and disease-preventing effects are obviously improved.

Description

technical field [0001] The invention relates to an aqueous suspension, in particular to an aqueous suspension containing bifenthrin and fluflufen, a preparation method and application thereof, and belongs to the technical field of chemical pesticides. Background technique [0002] Bifenthrin, English name: Bifenthrin, chemical name: Methylbiphenyl-3-ylmethyl (Z) (1RS, 3RS) 3-(2-chloro-3,3,3-trifluoropropane-1 -Alkenyl)-2,2-dimethylcyclopropanecarboxylate, which belongs to pyrethroid insecticide and acaricide. Bifenthrin has the characteristics of strong knockdown effect, broad spectrum, high efficiency, rapidity, and long residual effect. It mainly has contact killing effect and gastric toxicity, and has no systemic effect. It is suitable for cotton, fruit trees, vegetables, tea and other crops , can be used to control cotton bollworm, pink bollworm, tea geometrid, tea caterpillar, apple or hawthorn red spider, peach small borer, cabbage aphid, cabbage caterpillar, diamondb...
