Resistance to Dodine in Populations of <i>Venturia inaequalis</i> in Quebec, Canada

Fig. 3. Frequency distributions of Venturia inaequalis isolate sensitivities to dodine for (A) isolates from never treated trees sampled in Quebec during the summer of 2003; (B) isolates from commercial orchards sampled in Quebec during the summer of 2003. ED50 values (in μg/ml are based on mycelial radial growth on PDA amended with different doses of the fungicides for four weeks.
