Problems solved by technology

However, most of the pesticide compounds have additive effects, some even have antagonistic effects, and only a few have synergistic effects, especially combinations with obvious synergistic effects and high co-toxicity coefficients.
After a large amount of indoor and field explorations, the present inventors found that pyridalyl, respectively combined with butylene-fipronil and fenoxycarb, has obvious synergistic effect, and about pyridalyl, respectively with butylene-fipronil, Reports about the compounding of fenoxycarb have not yet been made public

Embodiment 1

[0022] 10% Pyridalyl-Butene Fipronil Suspension Concentrate

[0023] Pyridalone technical (Zenbai) 5%, butene fipronil technical (Zenbai) 5%, naphthalenesulfonic acid sodium salt 1%, EO-PO clamp ether 2.5%, antifreeze urea 5%, 0.5% xanthan gum, 2% magnesium aluminum silicate, 0.8% 20% polydimethylsiloxane emulsion, water to make up to 100%; the preparation method is to weigh and mix water, additives, and the original drug, and sand to D90≤5um, the product can be obtained after filtration. Substituting butene fipronil for fenoxycarb can also produce a suspension.

Embodiment 2

[0025] 10% Pyridalyl-Butene Fipronil EC

[0026] Pyridalipr technical (diluted) 5%, butene fipronil technical (diluted) 5%, anhydrous calcium dodecylbenzenesulfonate 3.5%, triphenylethylphenol polyoxyethylene ether phosphoric acid Ester 5.5%, mineral spirits make up to 100%; the preparation method is to mix the solvent, auxiliary agent, and original drug by weighing and stirring until clear and transparent, and obtain the product after filtration. The emulsifiable concentrate was also obtained by replacing butylene fipronil with fenoxycarb.

Embodiment 3

[0028] 10% Pyridalyl Fenoxycarb Microemulsion

[0029] Pyridalone technical product (Zenbai) 5%, fenoxycarb technical drug (Zenbai) 5%, fatty alcohol polyoxyethylene ether 3%, 3-octylpyrrolidone 5%, propylene glycol 3%, silicone oil 0.2%, Deionized water was added to 100% and mixed to prepare 10% pyridalyl-fenoxycarb microemulsion. Replacing fenoxycarb with butylene-fipronil also resulted in a new dosage form.

Abstract

The invention discloses a pesticide composition containing pyridalyl, and belongs to the technical field of pesticide compounding. The pesticide composition is used to solve the increasingly serious problem of pest resistance. The pesticide composition comprises the active ingredients of an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from the pyridalyl, and the active ingredient B is selected from one of butene-fipronil and fenoxycarb; the weight radio of the active ingredient A and to active ingredient B is (40:1)-(1:40), and the balance is auxiliaries. The pesticide composition has the advantages of being obvious in synergistic effect, wide in spectrum of prevention and treatment, good in prevention effect, time-saving, labor-saving, less in dosage and low in residue, can effectively delay the production of the pest resistance, protects the human and livestock safety, reduces the environmental pollution, and has a high application value in the comprehensive treatment of agricultural pests.

Description

technical field [0001] The invention belongs to the field of compounding agricultural insecticides, and in particular relates to a pesticide composition containing pyridalyl. Background technique [0002] Pyridalyl (trifluroxyfen) chemical name: 2-[3-[2,6-dichloro-4-[(3,3-dichloro-2-propen-1-yl)oxy]benzene Oxygen] propoxy] -5- (trifluoromethyl) pyridine, chemical formula: C 18 h 14 Cl 4 f 3 NO 3 . Pyridalyl is a high-efficiency and low-toxicity insecticide developed by Japan’s Sumitomo Chemical Company. It has obvious contact and stomach poisoning effects, and its effect is relatively fast. A cytotoxin, which has excellent control effect on Lepidoptera on vegetables and cotton, and has less effect on non-target beneficial insects, and is expected to become a promising compound in integrated pest management (IPM). [0003] Butene fipronil (butene fipronil) chemical name: 3-cyano-5-methallylamino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4 -Trifluoromethylsulfinylpyrazo...
