Photodegradation of 1-((6-chloropyridin-3-yl)methyl)-7-methyl-8-nitro-1,2,3,5,6,7-hexahydroimidazo[1,2-a]pyridin-5-ol (IPPA152001) and 1-((6-chloropyridin-3-yl)methyl)-7-methyl-8-nitro-5-propoxy-1,2,3,5,6,7-hexahydroimidazo[1,2-a]pyridine (IPPA152004) was studied in distilled water; high-pressure mercury lamp and xenon lamp were used as light sources. The photolytic rate constants of the two compounds and their half-lives were calculated. Compared with imidacloprid, the order of photodegradation rate of three compounds was as follows: imidacloprid > IPPA152001 > or = IPPA152004...
