METHOD AND KIT FOR DETERMINING THE CONCENTRATION OF A NEONICOTINOID INSECTICIDE AND ANTIBODIES APPLIED IN THE TEST

摘要

The antibodies of the invention are selective for compounds of formula I wherein A is 2-chloro-5-pyridyl or 2-chloro-5-thiazolyl; R and R 3 are independently hydrogen or C 1-4 alkyl; R1 and R2 are independently hydrogen or C1-C4 alkyl, or R1 and R2 taken together with the nitrogen to which they are attached form an imidazolidine or oxadiazine ring; and X is = N-NO 2 or = N-CN. The invention also relates to antigen-neonicotinoid conjugates (immunogens) and agents for their preparation. The method according to the invention can be applied to plant propagation material, for example, to determine the concentrations of seed-grafted neonicotinoid insecticides. SHE
