Example Embodiment

[0028] Example: Joint toxicity experiment of fipronil and spirotetramat in different ratios.

[0029] 1.1 Test agents

[0030] 97% fipronil original drug, 95% spirotetramat original drug, the above-mentioned original drugs are provided by the R&D department of Hailier Pharmaceutical Co., Ltd.

[0031] 1.2 Test target

[0032] The third-instar larvae of the sensitive beet armyworm with the same individual size and physiological status were kept indoors for 5 consecutive generations. Temperature (25±2)℃. The relative humidity is 65%±5%, and the photoperiod is 12 / 12h (L / D).

[0033] 1.3 Experimental steps

[0034] 1.3.1 Pharmaceutical preparation

[0035] First dissolve the original drug with acetone, and according to the results of the preliminary experiment, mix the two original drugs into 7 different ratios, and then use acetone to dilute each treatment into 7 concentration gradients for use, 7 fipronil and snails The ratios of the effective ingredients of the ethyl esters with...

Abstract

The invention relates to an insecticide composition containing fipronil and spirotetramat. The active ingredients are obtained by binary compounding of fipronil and spirotetramat, wherein the mass ratio of the fipronil to the spirotetramat is (14-32): (24-6); the mass fraction of the active ingredient fipronil to the active ingredient spirotetramat in the preparation is 1%-80%, the rest is auxiliary element which is allowed for use or accepted in pesticide. The form of the insecticide composition provided by the invention is missible oil, suspending agent, wettable powder, water dispersible granule, emulsion in water and microemulsion. The insecticide composition containing fipronil and spirotetramat provided by the invention is mainly used for preventing and controlling leafhoppers, plant hoppers, plutella xylostellas, pieris rapaes, aphids, thrips, phylloxeras, mealybugs, aleyrodids and scale insects.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing fipronil and spirotetramat. Background technique [0002] Fipronil is a phenylpyrazole insecticide with a wide insecticidal spectrum. It mainly has gastric toxicity to pests, and also has contact killing and certain systemic effects. Its mechanism of action is to hinder insect γ-aminobutyric acid Controlled chloride metabolism, so it has high insecticidal activity against important pests such as aphids, leafhoppers, planthoppers, Lepidoptera larvae, flies and Coleoptera, and has no phytotoxicity to crops. It has a high level of control effect on diamondback moth, cabbage butterfly, rice thrips, etc., and has a long lasting effect. Chemical name of fipronil (RS)-5-amino-1-(2,6-dichloro-a,a,a-trifluoro-p-tolyl)-4-trifluoromethylsulfinylpyrazole -3-carbonitrile, whose chemical structure is . [0003] Spirotetramat is a tetern...
