Abstract
To investigate runoff losses of azoxystrobin from the field by rainfall, the influence of slope degree and length on runoff rate of azoxystrobin from the pepper field were measured. The SC type formulation was applied at the pepper field lysimeter in 2004 and 2005. The azoxystrobin washed down from plant were from 21% to 68% of what the applied. Concentrations of azoxystrobin in the first runoffs were less than $50{\mu}gL^{-1}$. Runoff losses were from 0.26% to 0.59% for 10% slope-plots, from 0.66% to 0.96% for 20% slope-plots, and from 0.84% to 1.78% for 30% slope-plots. Then they decreased with increasing slope-length. Runoff loss of azoxystrobin was closely related to volume of runoff, it was reduced by the ridge and the mulching effect.
