Marrone Bio Innovations, Inc. announced the launch and commercial availability of a new formulation of its REGALIA® Biofungicide. In 2015 field trials conducted with university and 3rd party evaluators in the northeastern U.S., the new formulation of REGALIA also showed improved efficacy against fire blight, providing pome fruit growers with a valuable management tool that can be used to delay the development of resistance to antibiotics while providing enhanced control of shoot blight. This research also showed very promising spray programs when REGALIA was tank mixed with copper fungicides or prohexadione-calcium, achieving control comparable to antibiotics.

Key attributes of the new REGALIA formulation include: Easier mixing and dispersability in the tank leading to increased time back in the field spraying versus loading; No film left in empty containers that ensure all product is used and improved rinse-out recycling; A bold green container color with clear fill-line allowing handlers to see how much product has been poured out. As part of an integrated disease management program, REGALIA can be used to control plant pathogens on a wide range of crops including, but not limited to grapes (powdery mildew, Botrytis), almonds (brown rot, shot hole, powdery mildew), strawberries (powdery mildew, Botrytis), tomatoes (powdery mildew, Botrytis/gray mold, bacterial spot and speck, early blight), apples (powdery mildew, fire blight), and cucurbits such as watermelons, pumpkins, and cucumbers (powdery mildew, gummy stem blight, downy mildew).
