2005 Weed-Free Program
Illinois Crop added the weed-free forage and mulch program to its portfolio under a program administered by the North American Weed Management Association. Today, accreditation is done through the North American Invasive Species Management Association (NIASMA). Illinois Crop has expanded with the program and now includes quarry inspections for weed-free rock and construction materials. The NAISMA Certified Weed Free Products program is the only program in North America that provides federal, state, tribal, and local land managers a way to mitigate noxious weeds spread through the movement of forage, hay, mulch, gravel, or compost brought into a managed property.
