Disease control of blast, sheath blight, brown leaf spot, narrow brown leaf spot, seed and seedling diseases, stem rot and straighthead.
Blast is the most important disease of rice worldwide and the second most important in Louisiana. Yield losses as high as 75 to 90 percent have been observed in Louisiana due to this disease. Use this fact sheet to help you identify and manage rice blast. (PDF Format Only)
