FMC assures Anthem® Flex herbicide provides 80% Italian ryegrass and annual bluegrass control up to 45 days after application in winter wheat.

Anthem Flex herbicide is a highly effective herbicide for the control of several problematic winter annual grasses in fall-planted wheat when used according to label directions. Apply 2.5-4.5 fl. oz./A (see chart below) of Anthem Flex herbicide per acre as a delayed preemergence application to winter wheat. The delayed preemergence application timing is defined as 80% of planted wheat seed having a radical at least 0.5 inches long but prior to wheat spiking. This usually occurs three to five days after planting but can vary widely depending on soil moisture and temperature.

FMC assures 80% Italian ryegrass or annual bluegrass control up to 45 days after application if the following conditions are met:

  • Wheat is planted into a weed-free seedbed with no Italian ryegrass and annual bluegrass germinated or present. Paraquat or other labeled herbicides effective on Italian ryegrass herbicides may be used to ensure no emerged grasses are present at planting.
  • Anthem Flex herbicide is applied delayed preemergence as described above.
  • The correct label rate is applied according to soil texture. Reduced rates for the appropriate soil type should not be expected to provide adequate control and will be serviced accordingly.
  • At least 0.5 inches of rainfall and/or irrigation occurs within 10 days after application.
  • Grower must have an untreated check in order to determine level of grass control achieved.

In the event a grower does not achieve at least 80% control up to 45 days after application, FMC will pay up to $8/A toward the cost of a postemergence herbicide application.

 To be eligible for this program, the grower needs to contact their FMC retail market manager or Star Retailer before making an application of a postemergence herbicide.
