Other claims from this paper (16)
- Association Panicle symptoms increased with seed infection.
- Observation Healthy-looking panicles and branches could yield infected seeds.
- Intervention effect Winnowing significantly reduced seed infection.
- Intervention effect Sun-drying significantly reduced seed infection.
- Observation P. oryzae sporulation on germinating seeds was usually at the embryonal end.
- Observation P. oryzae sporulation on most nongerminating seeds covered the seed surface.
- Observation Seed-to-seedling transmission was consistently low.
- Observation Light soil covering allowed seed transmission.
- Observation Moist seeding without covering allowed seed transmission.
- Observation Complete covering rarely yielded transmission.
- Observation Water seeding yielded no observed transmission.
- Observation Seedling infection frequency was lower in unsterilized soil.
- Observation P. oryzae recovery was higher in sterilized soil.
- Observation P. oryzae recovery from infected seeds declined over time.
- Observation Seedlings at 15 to 20°C did not develop blast lesions.
- Intervention effect Blast lesions appeared after seedlings moved to 25 to 30°C.
