DuPont Afforia herbicide - Technical Bulletin
Technical Bulletin Registration status
DuPont™ Afforia™ herbicide is a developmental product for which an application has not been filed with EPA. This developmental product is not registered for use and sale in the United States, and no sale, offer for sale or use of this product may be made unless and until all necessary federal and state registrations have been obtained.
General information
Application information
DuPont Afforia herbicide has been tested as a burndown plus residual control herbicide that may be applied preplant to soybeans. In field trials it has delivered:
The Afforia™ proposed label will include directions for use for ground or aerial equipment.

™
Effective burndown of winter annuals, dandelions and volunteer canola. Consistent control of the toughest weeds, including kochia, lambsquarters, marestail, pigweed species, waterhemp, common ragweed and other broadleaf weeds. (See the weed control chart on the back for a list of weeds controlled and suppressed and specific application rates/directions used in field trials.) Improved weed resistance management over glyphosate alone with two additional modes of action. Rotational crop flexibility. Excellent burndown and residual performance even under cool, wet spring conditions.
Rate application DuPont™ Afforia™ was tested at a rate of 2.5 ounces per acre.
Tank mixtures
Weed resistance When herbicides with mode of action classifications that affect the same biological sites of action are used repeatedly over several years to control the same weed species in the same treatment area, naturally occurring resistant biotypes may survive, propagate and become dominant in that area. To better manage herbicide resistance, it may be necessary to change cultural practices within and between crop seasons, such as using a combination of tillage, retreatment, premix products, tankmix partners or sequential herbicide applications that have multiple sites of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes. Afforia™, which contains the active ingredients tribenuron, thifensulfuron and flumioxazin, is a Group 2 and Group 5 multiple mode of action premix herbicide based on the HRAC mode of action classification system of the Weed Science Society of America.
Afforia™ tank mixed with glyphosate and/or 2,4-D provided cross-spectrum burndown at preplant as well as residual control.
Application timing Afforia™ was applied to soybeans in the spring, preplant, up to 1 day prior to planting. Studies have shown that Afforia™ should not be applied to cracking soybeans or after the soybean crop has emerged because severe injury or death of the crop will occur.
Formulation Afforia™ is a dispersible granule formulation, mixed in water and applied as a spray solution to control susceptible broadleaf weeds in soybeans. Afforia™ contains two active ingredients to broaden broadleaf activity.
