I wouldn’t say the numbers we are seeing are anything of great concern, but the numbers are higher than we normally see this time of year. This tells us that fall armyworms are in the environment and capable of moving into rice. As the wheat is drying down, make sure to keep a close eye on field edges, especially those fields adjacent to wheat.
