Other claims from this paper (6)
- Intervention effect Complete removal of infected tissues delayed strawberry powdery mildew onset.
- Intervention effect Complete removal of infected tissues reduced disease severity by up to 88%.
- Observation Chasmothecium formation increased in late summer following 8 and 16 cumulative hours below 13 C in the two years.
- Observation Chasmothecia, alone or on debris fragments fallen into the substrate, were excluded as triggers of infection, supporting the sanitation practice.
- Observation The highest infection rate was observed on 15-day-old class age leaves.
- Recommendation The authors conclude that sanitation such as removing overwintering infected leaves reduces early-season infections.
