- Association Coffee leaf rust isolates differed significantly in incidence on coffee plants, largely associated with their site of origin.
- Association Isolates from San Ramón had higher levels of aggressiveness components, such as infection frequency of 7.5–9.
- Association Isolate aggressiveness was associated with a reduction of up to 28% in SPAD readings of coffee plants.
- Association Isolate aggressiveness was associated with a reduction of up to 42% in Fv/Fm of coffee plants.
