Corn earworms are beginning to show up in parts of Louisiana, according to DEKALB® territory agronomist Fran Deville.  Pictured are two corn ears he observed recently in a farm field in Madison Parish in northern Louisiana.  On the right is Genuity® VT Triple PRO™ corn, which provides dual modes of corn earworm control.  On the left is an ear from a competitive trait product, without in-plant earworm protection, that shows earworm feeding.  Just three damaged kernels per ear can translate into a yield loss of one bushel per acre.  Deville says corn earworm pressure in the state is currently moderate but he expects it to get heavier moving into July.
