- Abstract
Trials with the fungicides Cuprozin WP (active ingredient copper hydroxide), Malvin WG (captan), Switch (cyprodinil and fludioxonil) and Signum (pyraclostrobin and boscalid) were conducted in two young blueberry orchards (variety 'Duke') severely affected by twig dieback. Treatments were sprayed twice during leaf fall in autumn 2011 or once during budding in spring 2012. No treatment had any effect against twig dieback. This result confirms earlier indications of winter frost damage of xylem tissue as the primary cause of these symptoms in Northern Germany. A colonisation of dead twigs by Godronia cassandrae was therefore probably the consequence, rather than cause, of dieback.
