The fungus Neonectria ditissima can cause European canker in apple nursery trees In this study ten treatments of EMLA 9 rootstocks budded with Royal Gala were examined 5 Treatments included combinations of five budding tapes two budding methods and three fungicidal treatments Fifteen months after inoculation all Tbudded trees had died Chipbudded trees inoculated after tying with either Flexiband type C or plastic precut strips displayed significantly more canker (21 and 22 respectively) than those tied with Buddy tape (11 P<0001) Of the uninoculated trees 9 displayed canker symptoms because either the budding wounds were infected by natural inoculum or the infection was present in the scion or rootstock before budding Treating buds with tebuconazole/carbendazim reduced canker symptoms significantly (2 P<0001) Calcium hydroxide also reduced canker symptoms (5) Pyraclostrobin/boscalid did not reduce canker incidenceDownloads
