Soil Management to Reduce Bacterial Foot Rot on Rice
Recognize the problem
first symptom of infection is the development of small water-soaked lesions on
the leaf sheath. The bacteria spread into nodes, stems and roots. Finally,
the stems turn black, rot and may collapse. The leaf blade also turns yellow
and produces a rotten smell which is typical for the disease and can help to distinguish
foot rot from other pests such as stem borers and Brown planthoppers. The
yield loss caused by foot rot may reach 30-40%.
Foot rot is more severe at high temperatures,
high humidity and high levels of nitrogen. The disease is also more common in
fields with a poor drainage system and soil oxidation. Hybrid varieties can
be more susceptible to foot rot than local varieties.
reduce the spread of disease from field to field, irrigation systems must be controlled
so that water from the infested field does not cross over to the non-infested
increase soil ventilation, inter-cultivation is needed. This should be done
approximately 25 days after transplanting
(56lb/acre) and Gypsum (6 viss /acre) are applied to get better soil conditions
