- Resource (flumiclorac) is a contact herbicide that controls velvetleaf (up to 10
inches tall) and pigweeds. Control of lambsquarters is variable, and some other broadleaf weeds will be suppressed.
- Mode of action: cell membrane disruptor.
- Apply when corn is in the 2- to 10-leaf stage and broadleaf weeds are in the 2- to 3-leaf stage for best results. Use a
directed spray if corn size prevents adequate spray coverage of weeds.
- Crop oil concentrate should be included when Resource is applied alone. Use 1
pint/A for broadcast application and 1 quart/A for directed application. Nitrogen fertilizer solution or ammonium sulfate can also be added to improve control of
large velvetleaf. Adjuvant recommendations vary with the tank-mix partner. See the label for more information.
- Apply in a spray volume of at least 10 gpa with a spray pressure of 30 to 60 psi.
- Allow 1 hour between application and rainfall.
