Developer: National Corn Growers Association, with assistance from Monsanto, DuPont Pioneer, Syngenta, and Dow AgroSciences; app information is available on the NCGA website.
Availability: Apple and Android mobile apps as well as a desktop version are availble.
Cost: Free

Intended Audience: Corn growers nationwide

Purpose of App: To help corn growers follow the appropriate Insect Resistance Management (IRM) requirements for different Bt corn hybrids.

Description: There is a great diversity of IRM refuge requirements for Bt corn hybrids. This app helps growers understand the appropriate IRM plans for the hybrids they grow.

Based on your location, you are shown a menu of Bt corn products available from different seed companies. Choose a hybrid, then enter the field size and seeding rate. The IRM refuge calculator displays the appropriate refuge size, the number of standard seed bags to plant for both traited and refuge hybrids, and possible planting configurations for planting corn products in the United States.

This refuge calculator does not replace or supplement the applicable manufacturer's IRM Grower Guide in any way. As a grower using this information, you are still obligated to understand and abide by the applicable IRM Grower Guide on planting and Insect Resistance Management. The desktop version allows printing reports summarizing the output.

Fit for Nebraska: This app is programmed to cover all major Bt corn seed companies and is updated as new products are labeled for use.
