Abstract
As the Georgia pecan industry continues to grow, new growers are learning both farming practices and pecan production. Particular to Southeast Georgia, small – medium producers manage their operations on a marginal budget. The markets for post emergent herbicides became volatile in 2021, raising the price of each herbicide. Pecan growers commonly rely mostly on these herbicides for weed control. Continued use of these post-emergent herbicides incurred a 200% increase in weed control per acre in 2021. The area pecan agent applied 10 different pre-emergent herbicide combinations and rates in a randomized block design for both research and demonstration. Ratings were taken at 30, 60 and 90 days after treatment (DAT). A field day was held to display both herbicide plots and costs per acre to pecan growers in Georgia.As the Georgia pecan industry continues to grow, new growers are learning both farming practices and pecan production.
