Embodiment 1

[0019] Example 1: 20% styrene-based 1,3,4-oxadiazole sulfide compound tefluthrin aqueous emulsion

[0020] Styryl-based 1,3,4-oxadiazole thioether compounds 10%, tefluthrin 10%, N-dodecylpyrrolidone 3.5%, biphenol polyoxyethylene ether 3.5%, xylene 10% , calcium dodecylbenzenesulfonate 5.0%, organic silicon 0.8%, water to make up to 100%. Specific operation steps: Dissolve styrene-based 1,3,4-oxadiazole sulfide compounds and tefluthrin original drug, solvent, and emulsifier, then mix with water, and undergo high-speed stirring and shearing in the reactor. The high-speed shearing of the cutting machine is to prepare 20% styrene-based 1,3,4-oxadiazole sulfide compounds·tefluthrin aqueous emulsion.

Embodiment 2

[0021] Example 2: 48% styrene-based 1,3,4-oxadiazole sulfide compounds tefluthrin microemulsion

[0022] Styryl-based 1,3,4-oxadiazole sulfide compounds 12%, tefluthrin 36%, tetramethylbenzene 10%, dibasic ester 5%, alkylphenol polyoxyethylene ether sulfosuccinic acid 8% ester, 3% epichlorohydrin, 1.5% polyether modified trisiloxane, 2% ethylene glycol, 0.3% silicone oil, and 100% deionized water. Specific operation steps: mix the above-mentioned materials in proportion, and after high-speed shearing and stirring, a 48% styrene-based 1,3,4-oxadiazole sulfide compound·tefluthrin microemulsion can be prepared.

Embodiment 3

[0023] Example 3: 36% styrene-based 1,3,4-oxadiazole sulfide compound tefluthrin suspension concentrate

[0024] Styryl-based 1,3,4-oxadiazole sulfide compound 8%, tefluthrin 28%, calcium lignosulfonate 5%, fatty alcohol polyoxyethylene ether 5%, benzoic acid 0.3%, silicon Ketones 0.1%, Magnesium Aluminum Silicate 1.5%, Sorbitol 2%, deionized water make up 100%. Specific operation steps: mix each component uniformly according to the ratio of the formula, grind and high-speed shear to obtain 36% styrene-based 1,3,4-oxadiazole sulfide compound tefluthrin suspension concentrate.

Abstract

The invention discloses a pesticide composition. The pesticide composition is prepared from two effective components of A and B, wherein A is a styryl-containing 1,3,4-oxadiazole sulfoether compound,and B is tefluthrin; a weight ratio of the components A to B is (1 to 10) to (10 to 1), and the weight sum of the effective components A and B accounts for 1 to 50 weight percent of the pesticide composition. The pesticide composition disclosed by the invention has an obvious synergistic effect, is capable of reducing the using amounts of the effective components and reducing the pesticide applying frequency and can be used for preventing and treating agricultural underground insects.

Description

technical field [0001] The present invention relates to the technical field of pesticides, in particular to a pesticide composition compounded with styryl-containing 1,3,4-oxadiazole sulfide compounds and tefluthrin and its application. Control plant root-knot nematodes, wireworms, mole crickets, cutworms, grubs and other underground pests. Background technique [0002] Tefluthrin can be used as a pyrethroid insecticide for soil treatment. It is highly effective against Coleoptera, Lepidoptera and Diptera insects and can be applied by soil spraying or seed treatment. Tefluthrin has good volatility and can fully move in the gas phase to control soil pests. It is reported that its half-life in the field is about one month, so it can maintain a long residual effect on pests without causing long-term residues in the soil. [0003] According to the report of patent CN106674147A, 1,3,4-oxadiazole sulfide compounds containing styrene groups have high nematicide activity and low t...
