Farmers need to continue to be vigilant in rotating herbicides to defend against the threat of glyphosate-resistant herbicides, according to Texas A&M AgriLife Extension Service specialist.
At the recent Texas Plant Protection Association Conference in Bryan, several talks addressed new technology and continuing weed control, plus a number of awards were presented during the annual business meeting.
Dr. Paul Baumann, AgriLife Extension state weed specialist, College Station, told attendees that weed resistance issues in Texas will continue in the future.
“We’ve got to keep the pressure on whether we are talking about common waterhemp or using alternative chemistries,” he said. “You just can’t let it go.”

Baumann said rotating herbicides in crops is a good management practice. Other than herbicides, hand-hoe labor is expensive and hard to come by.
“Unless you go out there and pull that weed up, you’ve still got to get control of it,” he said. “You’ve got to get ahead of the problem before it starts.”
Dr. Peter Dotray, Texas A&M AgriLife Research weed scientist, Lubbock, said there are a lot of fields “with lots of different biotypes.”
“If we control with the same approach year after year, you know what’s going to happen,” he said.
Dotray said just one Palmer amaranth plant has the capability of producing 500 to 600 million seed.
“Weed resistance is a real global issue that requires local solutions,” he said. “There’s no silver bullet coming in the next year or the next 10 years.”
Following the speakers, a number of agricultural professionals and students received association awards. The following were award winners:
