Regalia Provides Effective Control of Walnut Blight

New field trial data demonstrates that Regalia® Biofungicide from Marrone Bio Innovations (MBI) is effective at controlling walnut blight (Xanthomonas campestris), a difficult to control disease and the number one pathogen in walnut production.

Independent field trials in San Joaquin County in 2009 showed that Regalia plus a copper fungicide provides control that rivals industry standards. There was less than 1% walnut blight in plots treated with Regalia plus copper, and over 25% blight in untreated plots.
