Climate Data

Researchers at the University of Tennessee found that dallisgrass and bermudagrass sensitivity to postemergence herbicides can vary throughout the growing season. Weather data can be used to determine when dallisgrass and bermudagrass are most sensitive to herbicide application, and properly timed treatments offer increased control.​​
