Satisfy the refuge requirements this year
With rootworm control problems in western states, entomologists and agronomists are pointing to what’s happening there as a reminder that it’s important to meet refuge requirements. Type and amount of refuge vary by product.
Traci Bultemeier, an accounts manager for Pioneer Hi-Bred International Inc., based in Fort Wayne, says that complying with refuge recommendations is first and foremost if you’re serious about helping prevent development of resistant insects. She’s also an Indiana Certified Crop Adviser.
The insect management guidelines are set by the U.S. EPA. EPA must approve the required refuge for each technology.
Bultemeier says you may want to take advantage of some online help that’s available. Visit www.irmcalculator.com. Sponsored by the National Corn Growers Association, it helps guide you through the process of determining refuge requirements.
You may also want to Google “handy Bt trait table,” she says. You should find a table complied by Michigan State University and the University of Wisconsin that lays out the refuge required for each seed product.
Your seed rep should be able to help you figure out if you need to leave refuge, and if so, how much and where.
