- Observation Cardinal temperatures (minimum, optimum, maximum) for blighting of onion umbels inoculated with B. squamosa were near 9, 21, and 27 C.
- Observation Cardinal temperatures (minimum, optimum, maximum) for blighting of onion umbels inoculated with B. cinerea were near 12, 21, and 30 C.
- Observation Cardinal temperatures (minimum, optimum, maximum) for blighting of onion umbels inoculated with B. allii were near 9, 24, and 30 C.
- Observation Cardinal temperatures for mycelial growth on potato-dextrose agar of B. cinerea were near 5, 22, and 30 C.
- Observation Cardinal temperatures for mycelial growth on potato-dextrose agar of B. allii were near 5, 22, and 30 C.
- Observation Cardinal temperatures for conidial germination of B. squamosa on purified water agar were near 6, 15, and 30 C.
- Observation Cardinal temperatures for conidial germination of B. cinerea on purified water agar were near 3, 18, and 33 C.
- Observation Cardinal temperatures for conidial germination of B. allii on purified water agar were near 6, 24, and 33 C.
- Intervention effect Increasing free moisture duration after inoculation from 0 to 96 hr significantly increased the percentages of unopened florets, open florets and immature seed capsules of onion blighted at 21 C.
- Observation Free moisture duration of 12-24 hr was necessary for blighting of unopen florets of onion by each pathogen at 21 C.
- Observation Free moisture duration of 6-12 hr was necessary for blighting of open florets of onion by each pathogen at 21 C.
- Observation Free moisture duration of 6-12 hr was necessary for blighting of immature seed capsules of onion by each pathogen at 21 C.
- Association Natural incidence of onion flower blight was positively correlated with July rainfall in Orange County, New York, 1976 to 1981.
