- Group effort in tackling northeast Arkansas Roundup-resistant pigweeds.
- Effort paying off for cotton producers in Clay County.
COTTON PRODUCER GREG Engle, left, and Andy Vangilder, Clay County Extension staff chair, are part of a northeast Arkansas group dedicated to combating resistant pigweeds.
As for tweaking control programs, Vangilder is unsure about “what else we could do. If there was something else, I believe the farmers would try it.
“Normally, we start in the spring to get rid of the resistant horseweed. And they’ve dealt well with that – it’s not near the problem as it once was.
“Everyone has a different program. But if you don’t have a bad pigweed infestation, the Reflex program may not be something you have to have. But for those that are infested, it can work.”
Producers should be warned about Reflex, though. “We’ve had some bad experiences,” says Vangilder. “You won’t hear me recommend planting cotton then spraying it on the ground. I’m not knocking the product but there’s been too much injury taking that approach.”
Instead, he suggests, spray the Reflex, get a rain and then plant the cotton into it. “That works fine and has been a big help for us.”
Producer Greg Engle says he’s used that “on some of our worst fields. We’ve also sprayed our Direx and that works. We also use Dual and put Cotoran on top of rows.”
“So, they’re using two pre-emergence (products) and then come in with Roundup and Dual twice,” says Vangilder. “Then, they come in with hoods and get the middles with something like Gramoxone, if you’re really careful. And Direx or Valor is used for lay-by.
“It’s a total chemical program along with hand-hoeing -- whatever it takes.”
One thing producers are waiting on is appropriate varieties of LibertyLink cotton for Clay County. Vangilder says “there will be a bunch of producers planting those when they come around.”
Right now, one of the hardest things for Vangilder to impart is to be timely in dealing with pigweeds. “You can’t wait to spray or chop. You can’t push the window and wait until the pigweeds are five inches tall. That’s the wrong thing to do. You cannot be late in dealing with these.”
