Control of brown rot and shot hole in almond: 2009 field trial


We conducted a field trial to evaluate the efficacy of a synthetic fungicide (Pristine; boscalid and pyraclostrobin) and two organic fungicides (Regalia; extract of Reynoutria sachilinensis and JMS Stylet-oil; paraffinic oil) for management of two foliar diseases in almond. Pristine and Pristine alternated with Regalia effectively reduced symptoms of both brown rot and shot hole following three applications from red bud to post-bloom. JMS Stylet-oil and Regalia alone did not control the diseases.
