Weed Science Research
• 1.6 Total EFT to research• Since 1999, the Weed Science group has published 94
refereed journal articles, 8 book chapters, 259 published abstracts
• Funding: $2.5 million since 1999 • Impact: • Research that has lead to critical use exemptions ~$100
million/year and other herbicide registrations have had an economic impact of ~$1.5 million per year
• Tropical spiderwort has been most troublesome weed in cotton since 2001 with impact of ~$5.6 million per year in increased control costs
• Glyphosate-resistant Palmer amaranth has the potential to have an economic impact of $20 million per year in cotton alone
