Interpretive Summary:

Technical Abstract: Sheath blight, caused by Rhizoctonia solani AG1-IA, is one of the most important diseases affecting organic rice production in the southern US. Management of this disease is a challenge because no synthetic fungicides are allowed to be used under organic production systems. In this study, field trials were conducted under organic management at Beaumont, Texas over 3 years to evaluate the resistance of 27 cultivars and the efficacy of eight biocontrol agents for management of sheath blight.
