Description

Technical Field

[0001] The invention relates to the technical field of agricultural product detection, and specifically discloses a detection kit for nicotine insecticides in ginger. Background Art

[0002] Nicotinoid pesticides are a class of neuroactive insecticides that can bind to nicotinic acetylcholine receptors in the central nervous system of insects, resulting in receptor blockage and killing pests. During the growth of ginger, spraying nicotine pesticides can effectively kill pests in the rhizomes of ginger. However, when spraying nicotine pesticides, they can enter other tissues through the roots or stems and leaves of plants and exist in the form of original drugs or metabolites. If they are improperly applied or used excessively, it is very easy to cause excessive pesticide residues in ginger. In order to meet market requirements, it is necessary to detect and treat nicotine pesticides in ginger.

[0003] At present, the determination method of nicotinoid insecticides is mainly based on high-resolution quadrupole-time of flight mass spectrometry (UPLC-QTOF / MS) detection technology. A rapid screening and detection method for the residues of nicotinoid insecticides imidacloprid, thiamethoxam, clothianidin and their metabolites in ginger has been established. It can study the residue levels and degradation dynamics of imidacloprid, thiamethoxam, clothianidin and their metabolites in ginger under different storage temperatures, time and application concentrations, as well as the metabolic laws of imidacloprid, thiamethoxam and clothianidin during the storage of ginger, and study the short-term and long-term dietary intake risks of ginger.

[0004] In the prior art, during the detection of nicotine insecticides in ginger, it is necessary to put the prepared ginger sample solution containing nicotine insecticides into a detection kit, and then take them out separately for chromatographic detection when testing. However, when putting the sample tube for collecting the sample into or out of the kit, since there is no good separation function, it is easy for the taken sample part to adhere to or splash onto other sample tubes, contaminating other sample tubes, and easily causing mutual contamination between the sample tubes, interfering with the accuracy of the detection result.
