556 results about "Cypermethrin" patented technology

Cypermethrin is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition. Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers, including Raid, Ortho, Combat, and ant chalk.

Compound pesticide for fishing and preparation method and application thereof

The invention discloses a compound pesticide for fishing; the compound pesticide can be used for preventing aquatic livestock parasitic diseases caused by parasites such as trichodina, dactylogyrus, gyrodactylus, Chinese daphnia, lernaean, sporozoit and the like, belonging to the field of veterinary drugs. The ingredients of the compound pesticide for fishing are composed of radix sophorae flavescentis, betel palm, stone-like omphalia and cypermethrin; the preparation method of the compound pesticide is that: the radix sophorae flavescentis, betel palm and stone-like omphalia are weighted according to the proportion, refluxing and extraction are carried out, extracting solution is heated, evaporated and concentrated, and then cypermethrin, emulsifying agents, organic solvent and distilled water are added for preparation according to the proportion; the compound pesticide for fishing has the advantage of stable quality, convenient usage, low cost, having remarkable curative effect on the trichodina, dactylogyrus, gyrodactylus, Chinese daphnia, lernaean, sporozoit diseases of the aquatic livestock, rapid effect, thorough killing, small toxic and side effect and wide parasite expelling and killing spectra, and can effectively ensure health and safety of aquaculture animals.

Cultivation technique for hybrid oilseed sunflowers

A cultivation technique for hybrid oilseed sunflowers, which relates to a crop cultivation technique, is characterized in that the cultivation technique for the hybrid oilseed sunflowers includes the following method and steps: variety selecting: a short-straw, high-yield and stable-yield variety with good earliness needs to be chosen for spring sowing; soil preparation and fertilization: 5000 kilograms of well-rotted farmyard manure and 30 kilograms of nitrogen-phosphorus-kalium compound fertilizer are applied per mu, and after uniform application, the land is deeply tilled; sowing time: sowing is normally carried out within fifteen days after the mid of March, the hole sowing method is mostly adopted, and the density per mu is about 3800 plants; field management: after oilseed sunflower seedlings emerge, the seedlings are checked in time, the seedlings are supplemented in time, and when two to three pairs of true leaves appear, weeding, thinning and final singling are carried out by being in combination with intertillage; pest control: 50 percent of phoxim or solution 1000 times as much as chlorpyrifos can be chosen to be sprayed on the land surface at the seedling stage, the manual pest-catching method rather than pesticide can be adopted at the flowering stage, and highly effective cypermethrin pesticide can be chosen for pest control at the seed-setting stage; and timely harvesting: preferably, harvesting is normally carried out in late June to early July according to harvesting standards that: the backs of oilseed sunflower discs become yellow, bracts become brown, stems have yellow flowers, and seeds are hardened. The yield of the hybrid oilseed sunflowers cultivated by the cultivation technique is high, the oil yield rate is high, time and labor are saved, and the economic benefit is high.

Method for preparing porous difunctional adsorption material

The invention relates to a method for preparing a porous difunctional adsorption material, which belongs to the technical field of the environment functional material. According to the invention, the method uses Hypermer 2296 to obtain a stabilize high internal phase emulsion, an oil phase comprises a monomer methyl acrylic glycidyl ester, a cross-linking agent divinyl benzene, a solvent toluene and an initiator azodiisobutyronitrile, a water phase is a potassium sulfate aqueous solution; after the water phase and oil phase are mixed, a stable water-in-oil emulsion is prepared after stirring preparation, a macroporous foam polymer is prepared after thermal initiation polymerization; then dopamine microspheres are grafted to a macroporous foamed material by a biology adhesion method; and finally, tetrahydrofuran is used for removing sulfonated styrene core and shell to obtain the macroporous material adhered with the hollow dopamine. The product has the characteristics of water-soluble performance and oil solubility of two materials, the hollow dopamine can effectively increase a specific surface area of the material and metal ions can be absorbed; the macroporous foam contains a lot of ester groups and are convenient for adhesion of trifluoro-cypermethrin, and two harmful substances can be removed simultaneously.

Compound biogas slurry insecticidal liquid and preparation method

The invention relates to compound biogas slurry insecticidal liquid and a preparation method. The insecticidal liquid is the compound biogas slurry insecticidal liquid which is prepared by a pesticide and biogas slurry in weight by percent: 0.02-0.2 percent of beta-cypermethrin and the biogas slurry, and 0.003-0.05 percent of imidacloprid and the biogas slurry. The preparation method comprises the following steps of: taking out the biogas slurry from a middle-layer discharging port of a biogas fermentation tank of which the biogas is normally fermented for over three months, wherein the total solid content of the biogas slurry is 10-12 percent; standing for 30 minutes; filtering to remove particle impurities to prepare the biogas slurry; reasonably mixing the biogas slurry and the beta-cypermethrin or the imidacloprid according to the weight percentage; fully stirring the mixture; and uniformly mixing. According to the compound biogas slurry insecticidal liquid and the preparation method, the biogas slurry generated in the anaerobic fermentation process of poultry excrement wastes is adopted, and the commonly-used insecticide is reasonably matched, so that common insect pests of a plurality of vegetable crops of kidney beans, eggplants, cabbages and the like can be effectively prevented; the insecticidal liquid is simple in preparation method, easy to operate and convenient to use, can reduce the using amount of the pesticides, and is suitable for being popularized; and the insecticidal liquid has the characteristics of efficiency, environment friendliness and low cost.

Preparation method and application of molecularly imprinted solid phase extraction small column for separating pyrethroid pesticide

The invention discloses a preparation method and application of a molecularly imprinted solid phase extraction small column for separating a pyrethroid pesticide. The molecularly imprinted solid phase extraction small column for separating the pyrethroid pesticide is characterized by consisting of cypermethrin as template molecules, methacrylic acid as a functional monomer and ethylene glycol dimethacrylate as a cross-linking agent according to a mol ratio of 1:(2-8):10; and a pyrethroid pesticide molecularly imprinted polymer obtained with a mass polymerization method is filled into a polypropylene solid phase extraction small column to obtain the molecularly imprinted solid phase extraction small column for separating the pyrethroid pesticide. According to the invention, the pyrethroid pesticide in an aquatic product or a water environmental sample can be efficiently and selectively separated, enriched and purified. Compared with the liquid-liquid extraction and the conventional solid phase extraction, the molecularly imprinted solid phase extraction column disclosed by the invention has the advantages of high enriching and purifying efficiency, low consumption of organic solvent and the like.
