Relation of Pruning Time and Inoculation with Pseudomonas syringae van Hall to Short Life of Peach Trees Growing on Old Peach Land1

Year: 1976

Type: article

Abstract: Three-year-old peach trees [ Prunus persica (L) Batsch. cv. Elberta] growing on old peach land where a high incidence of bacterial canker was suspected in previous plantings, were pruned or pruned and inoculated with Pseudomonas syringae van Hall in October, December, February, or April. All trees pruned and inoculated in October or December were either dead or dying by May. P. syringae was recovered from all of the October-inoculated and from 86% and 71% of the December- and February-inoculated trees, respectively. Also, 43% mortality occurred in February-pruned and inoculated trees. Uninoculated but early-pruned trees showed severe short life or decline symptoms with 43% mortality following October and December pruning. On the other hand, April-pruned trees, whether inoculated or not, showed less short life or decline symptoms than early-pruned trees and no deaths occurred in April-pruned and inoculated trees.
