This study demonstrated that rice producers can reduce sheath blight losses by planting moderately susceptible to moderately resistant cultivars and improve rice grain yield by applying azoxystrobin at mid-boot to moderately susceptible,
susceptible,
and very susceptible cultivars.
Moderately susceptible cultivars were shown not to need fungicide applications in a previous study; however,
Spring's disease reaction in this study indicates it should be designated as a susceptible cultivar, and in some rating systems, Cheniere has a susceptible classification. Fungicide applications are not warranted on moderately resistant cultivars, especially if severe disease fails to develop on them.
