Eric, 

These are not my words, but are only something I quoted in an effort to rebutt. I market garden and have all of the species mentioned above without considering them a problem. I do use cover crops--of which corn is my favorite as it can even give Johnson Grass a set-back. But mechanical eradication is rarely on my agenda. I've found that the above "weeds" generally are my friends.
