Monsanto's Corn Traits Marketing Manager Matt Kirkpatrick says by logging into the site farmers can learn when corn rootworm larvae are hatching in their area, allowing for better timing to scout their fields for possible root damage. The corn rootworm hatch varies by geography, but typically occurs from early- to mid-June in the Corn Belt, and often coincides with the first appearance of lightning bugs.

The service is being sponsored for the third year by Monsanto and its Genuity brand.

Growers in the Corn Belt can sign up for the service at to receive e-mail alerts from May through September to learn when the insects pose a threat in their area. In 2011, more than 3,000 farmers visited the site.

Developed by climatologist and meteorologist Mike Sandstrom, the Insect Forecast Tool analyzes moth trapping data and weather patterns to issue one, tow and three-to-five day forecasts for corn earworm and western bean cutworm. The corn rootworm hatch is updated weekly and is based on soil temperature and Growing Degree Days.
