A revised label on Rely 280 herbicide means California growers can use the pesticide without using a closed mixing and loading system.

The new label was approved recently by the the California Department of Pesticide Regulation and the Environmental Protection Agency.

Rely 280 herbicide is a post-emergent burndown herbicide used to control annual grasses and broadleaf weeds. In California, it is labeled for use on horticultural crops including vines, tree nuts, berries, stone fruits, citrus and olives. The chemical formulation includes a surfactant for control of resistant and problematic weeds.

“Bayer and our agricultural stakeholders worked together to vigorously defend the sound science of our testing to remove the closed system application requirement and advocated for revisions to the rule. As a result, growers will continue to have the freedom to access and flexibility to use the most robust herbicide formulation in the grape and tree nut market versus generic alternatives with no closed system requirement,” Nevada Smith, Bayer horticulture product manager, said. “It is particularly advantageous in cropping systems where resistance is an issue.”

Rely 280 is a non-selective herbicide that kills tough weeds such as Palmer amaranth, giant ragweed and kochia. It can be applied year-round on permanent crops.
