Palmer amaranth, kochia, marestail, you name it — populations of glyphosate-resistant weeds are popping up more frequently, and it looks like no-tillers are taking note of it.

There’s no doubt that much of the rapid increase in no-tilled acres over the past 20 years is due to the extensive use of glyphosate-resistant corn and soybeans. Yet, extensive reliance on this single herbicide mode of action may be holding back the future growth of no-till. Even more worrisome is the impact it could have on simply maintaining the no-till acres we already have.
