[0033] Example 2 40% bifenthrin·fluflufen seed treatment dispersible powder

[0034] The formula is: 30 parts of bifenthrin as the active ingredient of the pesticide, 10 parts of fluflufen; the dispersant is 2.5 parts of sodium lignosulfonate, 2.5 parts of naphthalenesulfonic acid formaldehyde condensate sodium salt; the wetting agent lauryl 1.5 parts of sodium sulfate, 4.5 parts of sodium dodecylphenol polyoxyethylene ether sulfate; 3 parts of polyvinyl alcohol as film forming agent, 1 part of sodium carboxymethyl cellulose; 1 part of acid scarlet as coloring agent; diatom as filler Add the mixture of soil and kaolin mass ratio 1:4 to 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0035] Example 3 45% bifenthrin · fluflufen seed treatment dispersible powder

[0036] The formula is: 35 parts of bifenthrin, 10 parts of fluflufen, the active ingredients of pesticides; 2 parts of sodium lignosulfonate, 6 parts of sodium naphthalenesulfonic acid formaldehyde condensate as a dispersant; 3.5 parts of sodium sulfate, 4.5 parts of sodium dodecylphenol polyoxyethylene ether sulfate; 2 parts of polyvinyl alcohol as film forming agent, 1 part of sodium carboxymethyl cellulose; 2 parts of acid scarlet as coloring agent; diatom as filler Add the mixture of soil and kaolin mass ratio 1:4 to 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses a pesticide composition containing bifenthrin and fluxapyroxad and a preparation method and application thereof. The effective components of the pesticide composition are the bifenthrin and the fluxapyroxad, and the mass ratio of the bifenthrin to the fluxapyroxad is 2-6:1. According to the invention, the bifenthrin and the fluxapyroxad are compounded and prepared into seedtreatment dispersible powder, and the seed treatment dispersible powder has the advantages of good film forming property, uniform coating, high suspension rate, safety, low toxicity and the like, andthe pesticide composition has good prevention and control effects on pests such as grubs, wireworms, flea beetle, leaf beetle and the like, as well as various diseases such as crop potato black scurf, wheat sharp eyespot, rice sheath blight disease, sclerotinia rot of colza, loose smut of wheat, Tilletia controversa of wheat, Corn southern leaf blight, Sphacelotheca reiliana and the like, and isobviously improved in insecticidal and disease prevention effects compared with the single agent of the bifenthrin and the fluxapyroxad.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing bifenthrin and fluflufen, its seed treatment dispersible powder formulation and their preparation method and application, belonging to the technical field of chemical pesticides. Background technique [0002] Bifenthrin, English name: Bifenthrin, chemical name: Methylbiphenyl-3-ylmethyl(2)(1RS,3RS)3-(2-chloro-3,3,3-trichloropropane-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 bor...
