¹Reaction: R = resistant; MR = moderately resistant; MS = moderately susceptible; S = susceptible; VS = very susceptible. Reactions were
established from both historical and recent observations from test plots and in grower fields across Arkansas. In general, these reactions would be
expected under conditions that favor severe disease development including excessive nitrogen rates (most deseases) or low flood depth (blast).
²Based on reaction to common races of the rice blast fungus in Arkansas for the most part; however, Banks and other Pi-ta resistant gene based
varieties are susceptible to Race IE-1k, a previously rare race that has increased in importance in the state since 2004. All rice varieties should be
monitored periodically for blast since the blast fungus is capable of developing new races that can overcome known resistance genes.
