preparation example Construction

[0021] In the present invention, there is no special limitation on the preparation method of the film-spreading oil agent, which can be prepared in a manner known to those skilled in the art or by oneself. When the present invention adopts a self-preparation method, the preparation method of the film spreading oil agent is preferably: after mixing 3-trifluoromethyl-4-nitrophenol with a film forming agent, a surfactant, and a cosolvent, to obtain a film spreading oil. film finish. In the present invention, the mass ratio of the 3-trifluoromethyl-4-nitrophenol to the film-forming agent, surfactant and co-solvent is preferably 5:30:4:61; the film-forming agent preferably includes Methyl laurate and dodecyl alcohol fat; the mass ratio of said methyl laurate and dodecyl alcohol fat is preferably 25:5. In the specific embodiment of the present invention, the preparation method of the film spreading oil is preferably to combine 3-trifluoromethyl-4-nitrophenol with methyl laurate, do...

Embodiment 1

[0028] Mass percent composition is the preparation of 3-trifluoromethyl-4-nitrophenol film spreading oil of 5%: 5g 3-trifluoromethyl-4-nitrophenol is added to 25g methyl laurate (film-forming agent), after fully dissolving, add 5g dodecyl alcohol fat (film former), 4g alkylphenol polyoxyethylene decaether (surfactant) successively, finally add 61g oleic acid (cosolvent), obtain mass 100 3-trifluoromethyl-4-nitrophenol film spreading oil with a content of 5%.

Abstract

The invention relates to the technical field of alien invasive species control, and especially relates to application of 3-trifluoromethyl-4-nitrophenol in killing or preventing and controlling ampullaria gigas, a method for killing or preventing and controllingampullaria gigas, and a medicament. The invention provides application of 3-trifluoromethyl-4-nitrophenol in killing ampullaria gigas or preventing and controlling insect pests of the ampullaria gigas. The 3-trifluoromethyl-4-nitrophenol disclosed by the invention can be used for effectively preventing and controlling ampullaria gigas and is low in cost. A result of a specific embodiment of the invention shows that the 3-trifluoromethyl-4-nitrophenol has an obvious killing effect on the ampullaria gigas, and the prevention and controlling effect of the 3-trifluoromethyl-4-nitrophenol is equivalent to that of a common medicament niclosamide for killing the ampullaria gigas.

Description

technical field [0001] The invention relates to the technical field of alien invasive species control, in particular to the application of 3-trifluoromethyl-4-nitrophenol in killing or preventing apple snails, a method and a medicament for killing or preventing them. Background technique [0002] Apple snails, also known as big bottle snails, apple snails, are native to the Amazon River Basin in South America. Introduced to China as edible snails in 1981, it has become a very harmful invasive alien species because of its strong adaptability and rapid reproduction. Apple snails eat a lot and bite rice and other crop plants, which can cause severe yield reduction. They are veritable rice killers. In addition, the shells of apple snails are sharp, which can easily scratch farmers' hands and feet, and a large amount of feces can pollute water bodies. Each snail lays about 10,000 eggs per year, and the reproduction rate is astonishing. It can cause the extinction of other aquat...
