Fig. 7. Pictures from in vitro assays to assess treatment inhibition of Phytophthora infestans mycelial growth. Treatments shown include A, negative water control; B, copper (full) dosage; C, Frangula alnus high dosage, nonfiltered; D, F. alnus high dosage, filtered; E, F. alnus medium dosage, nonfiltered; F, F. alnus medium dosage, filtered; G, F. alnus low dosage, nonfiltered; and H, F. alnus low dosage, filtered. The bacterium associated with the F. alnus bark that colonized the plates in treatments shown in panels C and E was identified to be an Erwinia spp.
