All (Mostly) Quiet on the Insect Front
Despite relative calm with respect to insect pests in Illinois, reports continue to be received on cutworm injury, especially from the westernmost counties of the central third of the state. Where you can, keep scouting for at least two more weeks.
Just In--Rootworm Larvae Detected in Indiana
First instar corn rootworms were found in Indiana on June 4. In areas where saturated soils are common, rootworm larval populations are likely to experience considerable mortality.
Considerations for Postemergence Herbicide Applications in Corn
Application timing, corn staging and response, and herbicide-insecticide interactions are discussed relative to postemergence herbicide applications in corn.
Nitrogen Applications for This Spring
Exercise patience and wait to apply N, if it's needed, until weather conditions allow a more informed decision.
Reports are provided this issue for east-central, northern, southern, and west-central Illinois.
