Other claims from this paper (13)
- Observation After four hours, mean ascospore release ranged from 3.6 × 10 3 to 4.8 × 10 6 per milliliter of water.
- Observation After 24 hours, mean ascospore release ranged from 3.7 × 10 3 to 4.4 × 10 6 per milliliter of water.
- Observation Mean spore germination ranged from 0.7 to 24.1% after four hours.
- Observation Mean spore germination ranged from 2.4 to 24.9% after 24 hours.
- Association Ascospore release numbers and germination percentage had a significant inverse relationship.
- Observation Illinois samples consistently yielded the greatest ascospore release.
- Observation Illinois samples consistently ranked among those with the lowest germination percentage.
- Observation Wisconsin samples were among the lowest for ascospore numbers.
- Observation Indiana samples were among the lowest for ascospore numbers.
- Observation Wisconsin samples were among the highest for ascospore germination.
- Observation Indiana samples were among the highest for ascospore germination.
- Observation The findings support pathogen overwintering in multiple upper Midwest areas.
- Recommendation Future research should reduce infested corn residue to reduce initial infection.
