Resistance of the sheath blight pathogen to the popular strobilurin fungicides continues to increase, encompassing roughly half of Louisiana’s rice acres as well as one confirmed field in Mississippi. Although strobilurins still provide good sheath blight control in fields without resistance, the growing issue should reinforce the need to follow sound resistance-management practices, says Louisiana State University AgCenter plant pathologist Don Groth.
