Yaupon, yaupon and more yaupon. The war for ranchers against this perennial seems to never be over, but there are viable control measures, according to a Texas A&M AgriLife Extension Service experts, speaking at the recent O.D. Butler Forage Field Day and Camp Cooley Ranch.
“It’s a perennial and comes back even when controlling it at the shallow level,” said Dr. Vanessa Corriher-Olson, AgriLife Extension forage specialist from Overton. “Perennials can come back even from live root material. Yaupon is very invasive. You might have an area cleared and think you are done. However, that’s only temporary. It will come back.”
There are several herbicide products on the market that can be used. Corriher-Olson said a 15 percent mix of Remedy Ultra, triclopyr, with 85 percent diesel can be applied to yaupon that has been cut less than an hour after cutting down.
For stem spray treatments, producers can try a mix of 25 percent Remedy Ultra and 75 percent diesel. This can be applied any time of year but may work best when growing.
Corriher-Olson told attendees to avoid applying herbicide during times of high temperatures and heat.
