Reports of alfalfa weevil have been coming in pretty consistently for the last several weeks; we’ve now received reports as far north as Rockford. If you haven’t already, it’s a good idea to scout your alfalfa – look for defoliation (alfalfa weevil is the most likely culprit at this early stage) and confirm the continued presence of the small, green larvae before taking action. If you have a serious infestation and are in position to do so, consider cutting early to reduce the potential for further damage. Insecticide options are somewhat limited, and failures with lambda-cyhalothrin have been reported this spring.
