Corn Earworm
Remnants of Hurricane/Tropical Storm Francine will continue to spin in the mid-south region of the country for the next day or so before largely dissipating. Southeasterly wind flow on the northeastern and northern side of the system may lead to some isolated corn earworm moth flights into portions of the corn-growing region mainly from eastern Missouri, Iowa, and far southeast Minnesota eastward. Once this system dissipates, the focus will be on a rather persistent pattern featuring high pressure in the northeastern United States and low pressure in southern Canada, with potentially some influence from a potential tropical system moving into the southeastern United States next week. There is uncertainty in this tropical system, and if it does not materialize then the corn-growing region weather pattern may also change and become more progressive. For now, Low migration risks blanket a large portion of the corn-growing region later in the weekend and throughout much of next week especially west of the Great Lakes. Processing and fresh market growers with crops still at susceptible stages to corn earworms should continue monitoring traps and scouting fields until harvest.
