Guide to identifying and managing alfalfa and clover leaf weevils in alfalfa. While research in northeast Nebraska has shown that clover leaf weevil larva feeding does not cause yield reduction to first cutting alfalfa, alfalfa weevil feeding can cause severe losses to yield and quality of the first cutting. This is why it's important to correctly identify the type of weevil feeding causing damage.
As corn begins to emerge, be alert to the potential for damage from early season insects such as cutworms, wireworms, or white grubs. High risk factors and identification and treatment guides for these major early season insects are included.
Moth traps have been established at 12 sites in northeast, east central, southeast and south central Nebraska to monitor flights of armyworm, black cutworm, and variegated cutworm moths. Find weekly updates in CropWatch:
