The EPA has approved registration of Howler fungicide, the first product to be marketed by AgBiome Innovations and developed by AgBiome. Howler is a biological fungicide that targets diseases common to high-value crops.

“This is great news for specialty crop growers,” says John Rabby, AgBiome Innovations Commercial Director. “Howler provides preventive, long-lasting activity on a broad spectrum of soilborne and foliar diseases, with no special handling or storage required.”

Listed by the Organic Materials Review Institute for use in certified organic production, Howler is exempt from the requirement of tolerances in the U.S. Howler can be used at every phase of crop production with a zero-day pre-harvest interval (PHI) and a four-hour, restricted-entry interval (REI).

“Howler fights disease with three modes of action — metabolic, enzymatic, and exclusion — by competing with invading pathogens,” says Steve Ronyak, Field Biology Manager for AgBiome. The active ingredient actively destroys pathogenic fungi, stops fungal development, and protects plant surfaces.

State registrations are now pending.
