"Think Different
Weed scientists were surprised by both the dramatic increase of Palmer amaranth identified in Iowa last year and by its cause for expansion (contaminated native seed mixes from out of state). Indiana, Ohio, Illinois and Minnesota also reported contaminated seed issues, but to a lesser degree. While native perennial vegetation in these conservation plantings should smother Palmer amaranth over a period of a few years, the concern is that it may spread into neighboring crop fields."
