Abstract:

Sheath rot disease of rice, caused by Sarocladium oryzae, inflicts damage to the uppermost flagleaf sheath by infecting the sheath covering the young panicles at the booting stage. The young panicles are generally affected, leading to an increase in the number of chaffy, discolored, and shriveled grains and a reduction in weight and number of healthy grains. Because the disease inoculums increases in proportion from year to year, appropriate management of this disease under field conditions with fungicides and biopesticides is essential.
