The Environmental Protection Agency (EPA) has approved a new formulation of Marrone Bio Innovation’s fungicide Regalia, an effective and novel product for control of fungal and bacterial diseases in crops and ornamentals.
The new Regalia features an expanded label with additional crops and uses, a reduced four-hour re-entry interval and a pre-harvest interval of zero days. The new formulation provides improved physical characteristics for easier mixing and spraying.
The label expansion for Regalia includes new crops like berries, bulb vegetables, brassicas, legumes, pome fruits, stone fruits and tree nut crops in addition to the existing uses on tomatoes, peppers, cucurbits, grapes, leafy greens, strawberries and walnuts.
Regalia is made from an extract of Reynoutria sachalinensis, and has a unique mode of action that induces disease resistance to several fungal and bacterial diseases in treated foliage. Regalia also provides growers with an important tool in a fungicide resistance management program. Used in tank-mixes, program rotations and stand-alone, Regalia is proven to control several important fungal and bacterial diseases such as powdery mildew, downy mildew, Botrytis gray mold, early blight, late blight and bacterial leaf spot.
The product will be launched in the Southeastern United States in fall tomato, pepper and cucurbit crops. "Recent University of Florida tomato trials show outstanding control of late blight in conventional treatment programs that included Regalia," states Tim Johnson, head of product development for Marrone Bio Innovations.
"Growers who use Regalia will be able to economically reduce the amount of copper and mancozeb applied, with no sacrifice of efficacy," adds David Warman, director of North American sales. "Regalia provides one product that can be used in programs for control of several important diseases: bacterial spot, late blight, early blight and target spot."
"Another notable expansion to this new label is the addition of downy mildew for leafy vegetable crops, which is a major unmet need of western greens growers," Warman says.
"In addition, this new formulation is recognized by the National Organic Program (NOP) as fully compliant for use on organic crops.
