Last winter wehad two apricot trees removed because they were infected with coryneum blight. A few days ago we removed a peach tree badly damaged by a breaking limb last summer (fruit load), and I noticed it had coryneum blight lesions on the trunk. Can these spores remain alive on soil to infect plum trees I plan to plant in about a week? Is there any preventive step I could take to avert their infection? Thanks very much.
