Other claims from this paper (9)
- Observation Three Pythium isolate groups caused higher seed disease severity than two other groups.
- Intervention effect All isolates reduced emergence and tissue weight in at least some soybean cultivars.
- Association Isolate by cultivar interactions were significant.
- Observation Aggressiveness varied significantly among isolates within species across most disease parameters.
- Observation Pythium ultimum var. ultimum isolate PU 350 caused the most damping-off, stunting, and root rot overall.
- Association Root rot severity and seedling emergence were negatively correlated.
- Observation Archer and Maple Glen were more resistant overall than four other cultivars.
- Observation Some isolates were not very aggressive on any cultivar.
- Recommendation The authors emphasized identifying aggressive Pythium isolates for resistance screening or genetic mapping.
