Abstract:

A residue analysis method was established for tebuconazole. 1.0 mg/L of the tebuconazole standard working solution, bananas and wheat extraction, matrix spiked 1.0 mg/kg tebuconazole at -20℃, 4℃, 25℃ were preserved for 1 day, 3 days, 5 days, 7 days, 10 days and 14 days in the stability test. The results showed after 14 days tebuconazole decomposition rates of standard working solution were 6.95%, 9.94% and 15.92%, respectively. Tebuconazole extract after 14 days decomposition rates were 11.47% and 19.64%, 23.88% and 23.12%, 26.94% and 27.49%, matrix spiked samples decomposition storage for 7 days rates were 23.42% and 27.18%, 19.14% and 26.73%.
