I. pastinacae 8 claims

Interactor role: pathogen

Literal values, not normalised. 183,098 distinct spellings cover 1,706,259 claims; only letter case and spacing are merged, so “maize”, “corn” and “Zea mays L.” are three separate entries here. The By interacting organism view merges spellings of one organism through NCBI Taxonomy.

Infection of the flowers and seed of parsnip by Itersonilia pastinacae

A. G. CHANNON Annals of Applied Biology 1969. doi:10.1111/j.1744-7348.1969.tb02878.x

Other claims from this paper (7)

Observation Infected parsnip plants had root cankers, leaf spots, petiole lesions and inflorescence necrosis.
Observation The fungus was found on some seeds.
Observation Seed infection was generally superficial but sometimes deeper.
Intervention effect Thiram soaking eliminated seed infection.
Observation Heavily infected seed produced a low proportion of seedlings with cotyledon lesions.
Observation Hypocotyl lesions also occurred, though their fungal cause was uncertain.
Observation The outdoor test found no evidence that infected seed ultimately produced roots with Itersonilia cankers.

Observation Itersonilia pastinacae ballistospores first appeared in August and peaked in October or November in wet seasons.
Observation In dry seasons, spores were fewer and appeared later.
