Syngenta says the California Department of Pesticide Regulation has registered the company’s Orondis Ultra fungicide for use in vegetables, including leafy greens, Brassica and fruiting vegetables, and onions.
Orondis Ultra is registered in Arizona.
Syngenta says Orondis Ultra has a novel mode of action new to the industry which provides growers with a foundational fungicide with good control of oomycete diseases.
Available in a premix formulation, Orondis Ultra combines Orondis (oxathiapiprolin) and Revus (mandipropamid) fungicides to provide preventive and residual control of downy mildews, late blight, and other diseases.
It exhibits systemic and translaminar movement to effectively protect existing and new growth.
According to Syngenta, Oxathiapiprolin is the only active ingredient in FRAC Group 49 so growers can incorporate Orondis Ultra into a season-long management program without concerns about cross resistance to other products.
