Herbicide resistant weeds -- not just those resistant to glyphosate -- are continuing to wreak weed-management havoc.
“There are biotypes no longer controlled by previously effective herbicides,” says Aaron Hager, University of Illinois (U of I) Extension weed specialist. In one Illinois case, a waterhemp biotype is resistant to not only glyphosate, but also an additional three herbicide action modes.
The good news? Glyphosate (used on over 95% of soybean acres and 70% of corn acres) continues to be the cornerstone of most weed-control systems.
Remember the 1995 movie, "Mr. Holland's Opus?" Its end showed scores of former students who reaped lifetime lessons taught by a humble music teacher.
Well, Roger and Monie Thompson have created a similar "opus" -- a top career achievement that one accomplishes -- of young southwestern Ohio farmers. The Springfield, Ohio, producers have helped start 22 young farmers since the 1980s. It's their way of passing on the help they received from folks early in their farming career.
"Everyone helps everyone," says Roger.
So many factors can affect your bottom line.
