Embodiment 3

[0160] Example 3: Evaluation of some compounds on the insecticidal activity of diamondback moth

[0161] The tested insects were Plutella xylostella of Lepidoptera, and the sensitive strains were kept indoors. The middle and late 3rd instar larvae of Plutella xylostella were used as the test object, and the test method was the leaf dipping method.

[0162] Operation process: Accurately weigh each sample, add acetone to prepare 10g / L mother liquor, and dilute it to 500ppm with Tween 80 aqueous solution containing 0.5‰. Use a hole puncher with a diameter of 1.0 cm to make clean cabbage leaves into discs and immerse them in the liquid medicine, take them out after 10 seconds, dry them naturally, and put them into clean containers. Inject middle and late 3rd instar larvae of Plutella xylostella with the same growth into the container, and insert 10 test larvae into each treatment, and raise them at a constant temperature of 28°C. Three repetitions were set, and the control group...

Embodiment 4

[0163] Example 4: Evaluation of the insecticidal activity of some compounds against Spodoptera frugiperda

[0164] The tested insects were Spodoptera frugiperda of Lepidoptera, and the sensitive strains were kept indoors. The end-2nd instar larvae of Spodoptera frugiperda were used as the test object, and the test method was the leaf dipping method.

[0165] Operation process: Accurately weigh each sample, add acetone to prepare 10g / L mother liquor, and dilute it to 500ppm with Tween 80 aqueous solution containing 0.5‰. Use a hole puncher with a diameter of 1.0 cm to make clean corn leaves into leaf disks and immerse them in the liquid medicine, take them out after 10 seconds, let them dry naturally, and put them into clean containers. Insert the end-2nd instar larvae of Spodoptera frugiperda with the same growth into the container, insert 10 test worms into each treatment, and raise them at a constant temperature of 28°C. Three repetitions were set, and the control group wa...

Embodiment 5

[0166] Example 5: Evaluation of the insecticidal activity of some compounds against beet armyworm

[0167] The tested insects were beet armyworm of Lepidoptera, and the sensitive strains were kept indoors. The first instar larvae of beet armyworm were used as the test object, and the test method was the leaf dipping method.

[0168] Operation process: Accurately weigh each sample, add acetone to prepare 10g / L mother liquor, and dilute it to 500ppm with Tween 80 aqueous solution containing 0.5‰. Use a hole puncher with a diameter of 1.0 cm to make clean cabbage leaves into discs and immerse them in the liquid medicine, take them out after 10 seconds, dry them naturally, and put them into clean containers. Inject 1st-instar mid-stage larvae of beet armyworm with uniform growth into the container, and insert 10 test worms into each treatment, and raise them in a constant temperature incubator at 28°C. Three repetitions were set, and the control group was treated with an acetone...

Abstract

The invention discloses an N-difluoromethyl azole selenourea derivative or an agricultural pharmacology acceptable salt and application thereof. The structure of the N-difluoromethyl azole selenoureaderivative is shown as a general formula (I) or a general formula (II), and the definition of each substituent group in the formulas is shown in the specification. The compound shown in the general formula (I) or the general formula (II) shows insecticidal activity on pests in agriculture and forestry and other fields, and meanwhile, the compound shown in the general formula (I) or the general formula (II) is used as an insecticide, namely, the compound shown in the general formula (I) or the general formula (II) is used for preparing drugs for preventing and controlling pests in agriculture and forestry or other fields. The compound particularly has excellent insecticidal activity on Lepidoptera chewing mouthpart pests such as Plutella xylostella, Spodoptera frugiperda, Spodoptera exiguaand Spodoptera litura.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides, and in particular relates to an N-difluoromethylazole selenourea derivative or a pesticide acceptable salt and use thereof. Background technique [0002] Nitrogen-heterocyclic pesticides have the advantages of high insecticidal activity, broad spectrum, and low toxicity, and have become the dominant framework for the creation of new pesticides. In recent years, newly developed pesticides such as cyclopyrid, cyantraniliprole, sulfoxaflor, flupyfuranone, flunicamid, cyflumetate, cyantraniliprole, spirotetramat, Flupyrimin, etc. All are nitrogen heterocyclic derivatives, mainly derived from nitrogen heterocyclic rings such as pyrazole or pyridine. However, the long-term use of existing insecticides has resulted in relatively serious drug resistance and exchange resistance problems, which has increased the difficulty of pest control. In particular, major pests such as diamondback moth (Plut...
