Anisogramma anomala causes a stem canker of filberts, Corylus avellana. This disease became a threat to the main U.S. filbert growing region when it was introduced into the Pacific Northwest around 1968. Various methods of artificially inoculating filbert trees and seeds were explored. Less than 1% of potted filbert trees...

Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller,
is a serious threat to hazelnut (Corylus avellana L.) production. Resistant
cultivars offer the best control. Screening systems were needed to reliably
identify disease, particularly in immune progeny derived from 'Gasaway'. An
indirect enzyme-linked immunosorbant assay (ELISA) was developed using...
The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...
