Dr. Stanley Culpepper of UGA Tifton says 52 counties have the mutant pigweed.
He says they’re looking at cover crops and deep turning.
(You may know that as plowing.)
He hastily adds that they’re looking at other herbicides.
But he wraps up by saying we have to look at other methods
than herbicides: tillage and cover crops.
He frames it as diversity and integration.
What it really means is spraying poisons eventually
breeds weeds that refuse to be poisoned.
People, of course,
are not so lucky.
Steckle said we’ve now reached the point where we have to begin thinking in terms of controlling “resistant weeds” instead of “resistant marestail” or “resistant Palmer pigweed” because they are both beginning to show up in the same field.
“We have to manage them both,” he said. “There’s a new product from BASF called Sharpen that I’ve been looking at for five years and I’ve been very impressed with the marestail control. I still like dicamba, Roundup and Gramoxone.
“But if you have Palmer pigweed, too, then you’re going to have to overlap with residuals ― Cotoran, Caparol, Prowl ― to have any chance to do a good job of controlling them.”
