Marrone Bio Innovations Releases New Data for Regalia Biofungicide

New field trial data demonstrate Regalia’s (Reynoutria sachalinensis) effectiveness in controlling walnut blight, the number one pathogen in walnut production.

Independent field trials in San Joaquin County in 2009 showed that Regalia plus a copper fungicide proves highly effective. There was less than 1% walnut blight in plots treated with Regalia plus copper, and more than 25% blight in untreated plots.

Regalia received California DPR registration in January (Agronews 2010-01-13) and is now available to growers in California. It is rainfast in only one hour, allowing growers to apply protective sprays during the early spring walnut blight infection period. It is also fully compliant with the National Organic Program (NOP) and is an OMRI (Agronews 2009-11-24 ) listed material.
