Fields already at risk of seeing hatch continue are located in eastern Colorado, Kansas, central and eastern Nebraska, Iowa, northern Missouri, central and northern Illinois, southern Wisconsin, central and northern Indiana, much of Ohio, and southern lower Michigan. Additional corn rootworm hatches will be possible in the next week across southeast South Dakota, southern Minnesota, central and southern Wisconsin, central lower Michigan, and southwest Ontario, Canada. Growers included in the risk area should monitor their fields and consider digging up roots both in corn and soybean fields to assess the number of larvae present and their growth stage.
