- Observation Disease severity and total yield did not differ significantly between years.
- Intervention effect Water stress increased early blight disease severity.
- Intervention effect Water stress reduced total yield from 39 to 29 ton ha −1.
- Observation Genotype and stress-by-genotype and year-by-genotype interactions were significant.
- Intervention effect Stress increased disease severity in genotype 10/24‐R3 from 57 to 67.
