Figure 2 is a bar graph showing the percentage of powdery mildew isolates per Ontario orchard that have the G143A mutation, or mutant genotype associated with strobilurin resistance. The number of orchards are divided into 3 resistance level categories: Susceptible, if the mutant genotype is less than 10%; Shifted, if the mutant genotype is between 10-50%; Resistant, if the mutant genotype is greater than 50%. There are 10 Ontario orchards that are susceptible, 4 that are shifted, and 2 that are resistant.
