Field Trial Program

ASA is excited to welcome Valent U.S.A.Corporation as a new industry partner and supporter of the association’s efforts on behalf of US soybean farmers. One of the ways Valent is demonstrating their support for our association is through an opportunity for ASA members to participate in a field trial program to help address weed resistance challenges and advance soybean yields, while also providing members with the chance to try Valent’s Fierce(R) XLT Herbicide.

Growers from the following five states-IA, IL, IN, MO and OH –participated in the Fierce XLT Field Trial Program during the 2015 growing season. The information below contains details about the field trial requirements, enrollment information, grower responsibilities and compensation.

Growers who participated in the 2015 Fierce XLT Field Trial should read the details below under “Field Trial Reporting Details and Evaluation Form.”

At the end of this field trial program, ASA will report on the results of this research to all members.

Valent will work with participating growers to conduct field trials that utilize their preemergence herbicide Fierce XLT to help growers address weed resistance challenges and increase yield.  Specifically, this program will evaluate how the application of Fierce XLT as part of a pre-plant burndown program or as a preemergence herbicide can increase yield potential by providing greater control of ragweed and Amaranthus. ASA and Valent will provide growers with a report on the total results of the field trials. Growers will also earn rewards for reporting field trial yield results and weed control by species.

  • Growers will need to devote 20 acres treated with Fierce XLT at 4 oz/A and 20 acres treated with their standard herbicide program. The total 40 acres must be contiguous and uniform in fertility, weed pressure and all agronomic practices (other than the herbicide program).
  • A post-emergence herbicide program can be applied uniformly over the entire 40 acres if needed.
  • Upon completion of the enrollment form, a complimentary supply of Fierce XLT used for this specific field trial program will be provided free of charge to growers selected to participate in the field trial.
  • If field is reduced tillage, an effective burndown program must be applied with the Fierce XLT.
  • Growers will be required to allow a Valent representative to visit the test plot, take photos and gather agronomic data.
  • Grower must be able to harvest with a yield monitor and provide a yield map of the two treatments.
  • Growers must carefully review the field trial protocol, or program requirements, and complete the online enrollment form from Valent.
