Embodiment 1

[0019] Formulation Example 1: 12% metaflumizone·beta-cyfluthrin EC.

[0020] Metaflumizone 10%, Beta-cyfluthrin 2%, Non-ionic polyoxyethylene ether 4%, Epoxidized soybean oil 2%, p-aminobenzoic acid 0.5%, Emulsifier 1601# 10%, Emulsifier 500# 5 %, the balance is ethanol and xylene. Add the above formulas into the mixing kettle in sequence according to the proportion, and after stirring evenly, 12% metaflumizone·beta-cyfluthrin emulsifiable concentrate can be prepared.

Embodiment 2

[0021] Preparation Example 2: 22% metaflumizone·beta-cyfluthrin wettable powder.

[0022] Metaflumizone 20%, beta-cyfluthrin 2%, wetting agent pull-off powder 3%, dispersant NNO 10%, talcum powder 4%, and the balance is kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 22% metaflumizone·beta-cyfluthrin wettable powder.

[0023] Preparation Example 3: 25% metaflumizone·beta-cyfluthrin suspension concentrate.

[0024] Metaflumizone 22%, Beta-cyfluthrin 3%, Emulsifier 1601# 10%, Wetting Agent LS, Dispersant SOPA-270 3%, Bentonite 2%, Xanthan Gum 0.2%, Silicone Defoamer 0.5% , 5% glycerol, and the balance is deionized water. The above formula is pre-crushed according to the proportion, and then added to a sand mill for grinding. After high-shear mixing, a 25% metaflumizone·beta-cyfluthrin suspending agent is prepared.

Embodiment 4

[0025] Formulation Example 4 : 15% metaflumizone·beta-cyfluthrin emulsion in water.

[0026] Metaflumizone 14%, Beta-cyfluthrin 1%, N-Methylpyrrolidone 6%, Sodium dodecylbenzenesulfonate 6%, Polyvinyl alcohol 4%, Emulsifier 500# 5%, Silicone defoamer 0.4%, and the balance is deionized water. Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix the water-soluble components in the above formula with deionized water to obtain a water phase; under high-speed stirring, mix the oil phase and water phase to obtain a 15% Metaflumizone · Beta-cyfluthrin emulsion in water.

[0027] In order to measure the combined toxicity of metaflumizone and beta-cyfluthrin on lepidopteran pests, the inventors used 96% metaflumizone and 95% beta-cyfluthrin to treat metaflumizone and beta-cyfluthrin. Beta-cyfluthrin mixture was tested for indoor toxicity.

Abstract

The invention relates to a pesticide composition of metaflumizone and beta-cyfluthrin. The effective components of the pesticide composition are metaflumizone and beta-cyfluthrin, the weight ratio of metaflumizone to beta-cyfluthrin in the composition is (40 to 1) to (1 to 40), and the total mass percentage of metaflumizone to beta-cyfluthrin in the composition is 1-70%. The pesticide composition can be processed into emulsion, water emulsion, a suspending agent or wettable powder, and is used for preventing and controlling Lepidoptera or coleopteran pests on crops such as vegetables, cotton, paddy rice and the like. The pesticide application dosage is reduced, the pesticide application frequency is reduced, the pesticide application cost is lowered, and the pesticide composition is safe to the crops.

Description

technical field [0001] The pesticide composition involved in the present invention uses metaflumizone and beta-cyfluthrin as active ingredients and is used for preventing and controlling agricultural pests, especially for preventing and controlling Lepidoptera pests. Background technique [0002] Metaflumizone (metaflumizone), belonging to the semicarbazone class, is an insecticide with a new mechanism of action, which blocks the passage of sodium ions by attaching to the receptors of sodium ion channels. The drug is mainly fed by pests and enters the body to cause gastric poisoning to kill pests. It also has contact killing effect and no systemic effect. The drug has a good control effect on the target pests and larvae of all ages. After the insects feed, the drug enters the insect body and blocks the sodium ion channel on the axon membrane of the pest neurons through a unique mechanism of action, so that the sodium Ions cannot pass through the axonal membrane, thereby inh...
