Degradation dynamics of flubendiamide in different types of soils.

Residual dynamics of flubendiamide in three different types of soils were investigated under laboratory condition. Flubendiamide was applied at 5 and 10 μg g(-1) for each soil and samples drawn periodically were analyzed on HPLC. The results showed that the degradation of flubendiamide in soils were followed first-order kinetics and its average half-lives in three kinds of soils were ranged from 37.62 to 60.21 days. The persistence of flubendiamide in soils significantly increased in the order of coastal soil > red and lateritic soil > new alluvial.
