Abstract

The invention relates to an instrument for rapidly detecting the snail-killing agent of niclosamide on site, belonging to the technical field of the instrument for detecting. The instrument for rapidly detecting the snail-killing agent of niclosamide on site comprises a shell. A host, a rechargeable battery and a color comparison box are arranged in the shell. The shell has the functions of controlling the action of the instrument, collecting data, computing, displaying, storing and processing. The color comparison box is a sealed black cubic box, one side of the color comparison box is provided with a photoelectric cell, and the other end is provided with an LED lamp. The rechargeable battery is used for supplying working power to both the host and the photoelectric cell. The instrument can be used for rapidly and conveniently detecting the application dosage of niclosamide ethanolamine salt wettable powder on site.

Description

technical field

[0001] The invention relates to the technical field of detection instruments, in particular to an on-site rapid detection instrument for molluscicide niclosamide. Background technique

[0002] Niclosamide is currently the only molluscicide recommended by WHO, and 50% niclosamide ethanolamine salt wettable powder is mostly used in my country today. So far, there is no method suitable for rapid detection of niclosamide at home and abroad. Due to the existence of complex factors such as terrain and water volume, it is difficult to control the dosage of the drug in the process of spraying or soaking molluscs in the wild. The snails cannot be killed with a small dosage, and excessive dosage is a waste of financial resources. Dosage, supervision and monitoring of the killing process, and the establishment of on-site rapid and sensitive niclosamide drug detection methods and supporting instruments are very necessary. So far, the analysis methods of niclosamide inc...
