- Observation In dry seasons, spores were fewer and appeared later.
- Observation Spore concentration was highest around dawn and lowest during the afternoon.
- Observation The fungus occurred only to a small extent over bare ground.
- Observation I. perplexans ballistospores were fewer than I. pastinacae ballistospores, with similar seasonal and daily fluctuations.
- Observation I. pastinacae was isolated from parsnip leaves at or shortly after the first air trappings.
- Intervention effect Raising soil or peat ridges over roots reduced black canker.
- Intervention effect Defoliating plants reduced black canker on roots.
