Rice Sheath Blight Control
Sheath blight is the most destructive disease Missouri rice growers face. Crop losses may range from slight to heavy each year, depending on weather, the plant growth stage when infection occurs, the extent of infection and the rice varieties grown. The severity of sheath blight in Missouri has increased in recent years due to increased use of highly susceptible varieties, a lack of crop rotation, thicker stands and use of higher nitrogen (N) rates, and earlier planting dates.
