The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsion in water of high-efficiency trans-cypermethrin and fenoxycarb and its application. The active ingredients of the composition are beta-cypermethrin and fenoxycarb, wherein the weight ratio of beta-cypermethrin and fenoxycarb is, beta-cypermethrin:fenoxycarb=1:1-1:5, the compound combination It effectively resists the problem of pest resistance, alleviates the current problem of pest resistance to the greatest extent, thereby reducing the amount of pesticides used, and also alleviates the impact on the environment. It is in line with the trend of green and environmental protection in the future society. The combination of the present invention Plants receive the best crop protection effect.

The invention discloses an insecticidal composition containing fenoxycarb. The composition comprises the following active components in portion by mass: 1 to 50 portions of the fenoxycarb, 0.05 to 5 portions of abamectin, 0.01 to 1 portion of emamectin benzoate, and 0.1 to 10 portions of profenofos. The invention also discloses application of the insecticidal composition in the aspects of preventing and controlling rice leaf rollers, diamond back moths or beet armyworms. Proved by field pesticide efficacy test, the insecticidal effect of the composition is remarkably higher than correspondingsingle-dosage effect; and the composition has remarkable synergic function, not only enlarges the insecticidal spectrum, improves the control effect, reduces the control cost and reduces the using amount of a pesticide, but also avoids injury to beneficial insects.

The invention discloses a preparation method of bovine serum albumin-coated fenoxycarb nano-medicine for preventing and treating groove-orbital phenomenon. The process of wrapping fenoxycarb with bovine serum albumin for preventing and treating groove-orbital phenomenon adopts a physical embedding method. First, take a certain amount of bovine serum albumin (BSA) and dissolve it in double-distilled water to form an aqueous phase, and take a certain amount of fenoxycarb and dissolve it in acetonitrile to form an oil phase. Then, under the condition of high-speed stirring, the oil phase is added dropwise into the water phase, after emulsification for a period of time, it is cooled rapidly, ultrasonically pulverized to obtain a microemulsion, and cooled. Finally, freeze-dry to obtain fenoxycarb albumin nanoparticles. The new albumin nanoparticle preparation technology adopted in the method is to wrap the drug in the albumin without changing the albumin structure, which increases the drug loading and also has the effect of sustained release. The use of nanotechnology can reduce the amount, residue, cost and environmental pollution of chemical pesticides. At the same time, it can also improve the efficacy of pesticides, effectively increase the contact area between pesticides and target pests, and truly realize the high efficiency, low toxicity and safety of chemical pesticides.

The invention discloses a new process for synthesizing fenoxycarb, specifically disclosing a new process for synthesizing fenoxycarb with a composite catalyst. The new process includes using phenol and p-chloro The reaction of phenol produces 4-phenoxyphenol, and then the reaction of 4-phenoxyphenol and 2-chloroethyl ethyl formate produces fenoxycarb. The composite catalyst consists of a main catalyst monovalent Cu(I) compound such as Cu 2 O, CuCl, CuBr and cocatalysts are composed of nitrogen-containing heterocyclic compounds containing functional groups such as 1,10-phenanthroline, 2,2'-bipyridine, and 2,2'-biquinoline. The new process has the characteristics of fast reaction speed, mild reaction conditions and high product yield.
