The invention discloses pyrethroid pesticide residue degradation bacteria as well as a bacteria agent and an application. A strain is Bacillussp. DG-02 with the strain preservation number of CCTCCM2011382. The degradation bacterial agent prepared by applying the Bacillussp. DG-02 is low in production cost, convenient to use and good in degradation effect, can be directly used to reduce the residual amount of deltamethrin, fenpropathrin, lambda-clyhalothrin, beta-cypermethrin, beta-cyfluthrin and 3-phenoxybenzoic acid in soil and crops by more than 75%, the problem of overproof pesticide residue in agricultural production is solved, and the degradation bacterial agent is suitable for being used in a large scale in fruit and vegetable production export bases across the country or places with green food brand marks, and has great significance in promoting the production of nuisance-free agricultural products and green food.

The invention provides a cyclopropane carboxylic ester type compound having the structure shown as the formula (I), and a preparation and the application of the same. The cyclopropane carboxylic ester type compound can be used for preventing and controlling agricultural pests, especially lepidoptera pests, Homoptera pests, thysanoptera pests or coleopteran pests, such as beet armyworm, prodenia litura, cabbage caterpillar, plutella xylostella, cotton bollworm, oriental tobacco budworm, imported cabbageworm, snout moth's larva, aphid, armyworm, plant hopper, aleyrodidae, leafhopper, thrips or Phyllotreta vittata Fabricius. According to the invention, beta-cyfluthrin is used as a control, the effect of preventing and controlling the cotton bollworm and the aphid of the compound shown as formula (I) provided by the invention is tested, and the result shows that the compound provided by the invention has better prevention and control effect on the cotton bollworm and the aphid than beta-cyfluthrin.

The invention relates to a clothianidin and beta-cyfluthrin suspending agent and a preparation method thereof. The suspending agent is prepared from the following raw materials in parts by weight: 20-25 parts of clothianidin, 5-10 parts of beta-cyfluthrin, 4-7 parts of a composite dispersing agent, 0.2-0.6 part of a nonionic lipid emulsifier, 0.3-0.7 part of an anionic sulfonate wetting agent, 3-5parts of an anti-freezing agent, 1-1.5 parts of a thickening agent, 0.1-0.3 part of a preservative, 0.5-1 part of a regulator and 0.1-0.5 part of a defoaming agent , with the balance being water. Thesuspending agent provided by the invention is prepared by adding the composite dispersing agent, the nonionic lipid emulsifier and the anionic sulfonate wetting agent into effective components; through a compounding effect of the composite dispersing agent, the nonionic lipid emulsifier and the anionic sulfonate wetting agent, the mixing uniformity of the components of the suspending agent can besignificantly improved; the wetting and dispersing effects of the suspending agent on the surface of the root part of garlic can be enhanced; thus, the pesticide effect of the suspending agent is exerted to a maximum extent when the suspending agent is used in a low-temperature environment; and by addition of the anti-freezing agent, the storage stability of a product can be easily kept when thesuspending agent is used in the low-temperature environment.

The invention discloses antibacterial coating. The antibacterial coating comprises acrylic emulsion, water, graphite powder, hydroxymethyl celluloses, bentonite, titanium dioxide powder, beta-cyfluthrin, titanium dioxide and ion antibacterial agents. The antibacterial coating has the advantage that effective antibacterial effects can be realized by the antibacterial coating.

A composite insecticide for culturing edible fungus is prepared from beta-cyfluthrin, methylamino abamectin, emulsifier and solvent. Its advantages are broad spectrum, high effect (more than 85%), and durable acting (10-15 days).

The invention belongs to the technical field of pesticide, in particular to an insecticidal composition containing butyl chlorantraniliprole and pyrethroid and application thereof. The insecticidal composition takes butyl chlorantraniliprole and pyrethroids, such as cyhalothrin, beta-cypermethrin, beta-cyfluthrin or bifenthrin, which are compounded according to certain range of weight ratio, as effective components, and further adds auxiliary components to be prepared into a finished insecticidal preparation, is applied to the control of agricultural or forest pests, has the characteristics ofbeing safe, efficient and quick-acting, is long in lasting period, prolonged in service life of pesticide and good in control effect on resistant pests, and contributes to overcoming and delaying thedrug resistance of pests. The composition obtains efficient insecticidal effect with small dosage, and solves the problems that the existing pesticide dosage is high, pesticide is frequently used, and heavy environmental load is caused.

The invention discloses a method for extracting pyrethroid pesticide residue in a liquid sample. The method comprises the following steps: (1) taking the liquid sample to be detected, adjusting the pH value of the liquid sample to be 3, adding acetonitrile, and evenly mixing to obtain a uniform solution; (2) adding salting-out liquid into the uniform solution, and standing until layering; (3) after layering, taking the acetonitrile phase at the upper layer, filtering the acetonitrile phase by using a microporous filter membrane with the thickness of 0.45mu m, and then directly carrying out gas chromatography-mass spectrometry determination, wherein the liquid sample is preferably a high-salt or / and high-protein sample. The method for extracting the pyrethroid pesticide residue can be used for extracting and purifying pyrethroid pesticides such as bifenthrin, permethrin, beta-cyfluthrin and fenvalerate, thus reducing the consumption of organic reagents; furthermore, a centrifuge device, an ultrasonic device, a shaking device and the like do not need to be used in the method, so that the method is simple, rapid and high in recovery rate, and can be predicted; the method has good application prospect in the technical field of pesticide residue determination.
