Univ. of Illinois Variety Trials on Winter Hardiness and Burndown Characteristics
In 2005, U. of IL extention educator Mike Plumer began a three-year trial on annual ryegrass varieties, to determine which would be most able to withstand harsh Midwest winters. Simultaneously, he tested the same varieties on how easily they succumbed to herbicide in the spring. Click here to see a report of the results, published in 2008.
