Forfeit® 280 Herbicide Available to Avocado Growers

The California Department of Pesticide Regulation has issued a section 24(c) Special Local Needs registration for Forfeit® 280 (glufosinate-ammonium) herbicide for use in avocado groves. This registration is effective through October 31, 2029. Growers wishing to use Forfeit® must have a copy of the SLN label in their possession during use. The label can be found on the California Avocado Commission website.

As you may recall, in May 2024 we alerted the industry that the California Department of Pesticide Regulation (DPR) had finally approved the herbicide Rely® 280 (glufosinate-ammonium) for use in avocado groves in California. The process to get Rely® registered had taken about five years and was a much-needed tool for California avocado growers to manage glyphosate (Roundup®) resistant weeds.

Unfortunately, in late August we received word that BASF, the manufacturer of Rely®, had “chosen to discontinue production of Rely Herbicide.” This was shocking information to receive given the time that had been invested in obtaining this registration. And as we learned, it was a decision that was just as surprising to our contacts at BASF who had worked closely with us on the registration process.

The California Avocado Commission is grateful to Loveland Products for their willingness to support our application for an SLN registration for Forfeit®. We also are grateful to DPR for the rapid review and approval of our application. We know that glufosinate-ammonium is an important tool for growers and we are happy that this disruption was relatively minor and growers will have Forfeit® available to them for the spring weed management season.

As a reminder, Rely® (the BASF product) is still registered for use on avocados and is legal for use as long as supplies last, but growers must have a copy of the DPR approved label that has a stamp on it with the wording "LABELING ACCEPTABLE State of California Department of Pesticide Regulation Pesticide Registration" and can be found on the CAC grower website here: (https://www.californiaavocadogrowers.com/sites/default/files/Rely-280-NVA-2022-04-0598-0238-avocado.pdf).
