According to the ability of the field isolates of Gibberella zeae to grow on the PSA with varying carbendazim concentrations, three sensitivity levels of isolates were determined in vitro. The sensitive isolates could grow at 0.5 μg/ml, but could not grow at 100 μg/ml. The high resistant isloates could grow faster than R at 50 μg/ml, and also could grow at 100 μg/ml.No low resistant isolates, that could grow fast at 1.4 μg/ml but could not grow at 50 μg/ml, were found among the field isolates.
