Analysis of resistance risk and resistance-related point mutations in Cyt b of QioI fungicide ametoctradin in Phytophthora litchii.

These results suggest that Phytophthora litchii has a medium to high resistance risk to ametoctradin in the laboratory. Two changes, S33L and D228N, in PlCyt b are likely to be associated with the observed ametoctradin resistance. © 2022 Society of Chemical Industry.
