Effects of moisture and temperature on pesticide stability in corn flour

Yetong Liu, Xu Qin, Qiusheng Chen, Qiang Zhang, Ping Yin, Yongze Guo


Corn flour has been stored at different moisture content (without and with 10 % water) and temperatures (-20, 4 and 25 °C). A modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method was used to determine the degradation rate of five common pesticides (imidacloprid, carbendazim, triadimefon, acetochlor, and metolachlor) during the stored process using high-performance liquid chromatography with a diode array detector and gas chromatography with an electron capture detector. The results showed that five pesticides experienced almost no degradation at -20 °C in corn flour whether with or without water, and the half-life was 69.3-693.2 days. The degradation rate ranged from 1.7 to 7.8 % after ten days of application. Under 25 °C and 10 % moisture content, the half-life was sharply reduced to 5.8-14.4 days. Under this condition, the degradation rate ranged from 40.6 to 68.4 % after ten days of application, and the sequence from high to low of the five pesticides’ degradation rates was as follows: carbendazim, imidacloprid, acetochlor, metolachlor, and triadimefon. Therefore, low temperature and drying were beneficial to the storage of corn flour, but unfavorable to the degradation of pesticides in corn flour.
