[5] In the late summer, the bark of infected areas split and the lesions produce fruiting bodies called pycnidia.

[4] In the spring, spur blight can be mistaken for winter injury therefore it is important to scout for these signs in September to assess the potential damage that will be done in the following season.

Visible symptoms include purple and brown expansive lesions appearing below buds, leaves and the lower portion of the stem.

[4] Other methods include starting with disease free plants, buying cultivars that are less susceptible to raspberry spur blight such as Brandywine, Killarney, Latham and Newburgh, and avoiding cultivars that have greater susceptibility such as Royalty, Titan, Canby, Skeena, Willamette, Reveille, and Sentry.

Willamette readily infects with spur blight but is tolerant to the disease and still produces satisfactory yields.

[9] These include lime sulfur or copper application, captan/fenhexamid mixture (Captevate 68WDG) applied when 8-10" shoot growth, and Strobilurins.

Specifically, chitinases, when applied, were found to reduce lesion size, and control infection of internal tissues.

[10] Notably, the application of Phytoverm, a Streptomyces avermitilis metabolite, had a similar inhibitory effect on disease growth.

[11] Other plant pathogens have also been found to reduce the growth rate of casual agent D. applanata such as entornopathogenic fungi (Hyphomycetes).
