Herbicide injury database available here: https://plants.uaex.edu/herbicide/default.aspx
Contains more than 1,000 images

Database will enable agri professionals and homeowners to see images of plants and damage.

Agriculture professionals and homeowners now have an online reference if they suspect their plants have sustained injury from herbicides.

The new Herbicide Injury Database at https://plants.uaex.edu/herbicide/default.aspx, contains more than 1,000 images collected across two decades showing and cross-referencing herbicides and the types of damage to many types of plants.

The database was a collaborative effort among Cal Shumway, associate professor of agronomy at Arkansas State University and two weed scientists with the University of Arkansas System Division of Agriculture: Bob Scott and John Boyd.

“The photos mostly came from a collection obtained from nearly years of work to provide training plots for the inspectors of the Arkansas State Plant Board as well as county agents and other agricultural professionals,” Scott said. “The pictures are available for download and other resources such as a symptomology handbook and searchable pdf files can also can also be obtained at the site.”

The training was conducted initially by Shumway on the ASU campus and more recently has been under the direction of Scott at the Newport Extension Center.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
