Resistance Management Begins with Advisors
In a study
published in the Journal of Cotton Science, it is conservatively estimated
that glyphosate-resistant Palmer amaranth occurred on at least 185,000 acres in
North Carolina in 2008 and infests 22 counties including Pitt, home to Crop
Consultant Charles Rogister of Crop Production Services. In a recent interview Charles shared the
story behind his resistance management strategy.
After learning how weed
resistance was already impacting the region and how it would escalate if
preventive measures weren't taken, Rogister went on the offensive.
Rogister stresses to his
customers the need for changing it up when it comes to mode of action and being
timely with their herbicide applications.
Because, as Rogister puts it, resistant or not, if you spray pigweeds
that are too large, nothing is going to work like it's supposed to.
Rogister evaluated the
tools available and developed a proactive weed management strategy including
glyphosate and 2,4-D at burndown in cotton followed by Reflex®
herbicide broadcasted behind the planter and glyphosate plus Dual Magnum®
herbicide in the first over-the-top application.
Customers who took his
advice have been successful in both controlling resistant weeds and minimizing
the spread of resistance. As a true pioneer in the fight against weed
resistance in eastern North Carolina, Rogister has inspired many growers to
take the steps necessary to become true resistance fighters.
