Other claims from this paper (9)
- Intervention effect P. arrhenomanes reduced root development of five-day dry-seeded rice relative to noninoculated controls.
- Intervention effect P. myriotylum reduced root development of five-day dry-seeded rice relative to noninoculated controls.
- Observation Rice susceptibility to three Pythium species declined sharply two to six days after planting and seedlings were resistant by day eight.
- Intervention effect Exposure to P. arrhenomanes inoculum for two to three days sharply reduced rice emergence through floodwater.
- Intervention effect Exposure to P. myriotylum inoculum for two to three days sharply reduced rice emergence through floodwater.
- Observation P. dissotocum was less virulent and required longer exposure for irreversible seedling damage.
- Intervention effect Deeper planting water increased rice seedling disease incidence.
- Recommendation The authors recommend early floodwater management to control rice seedling disease.
- Recommendation The authors considered biological control feasible because embryos are the main infection site and susceptible for only a few days.
