FPL 42 - Poplar Shoot Blight

The information accessed from this screen is based on the publication: Hunt, R. S. 1978. Poplar Shoot Blight. Forestry Canada, Forest Insect and Disease Survey, Forest Pest Leaflet No. 42 3p.

Introduction

Poplar shoot blight in British Columbia and the Yukon Territory is usually caused by members of the genus Venturia (Ascomycetes) or, less commonly, by invading canker fungi or the bacterium Pseudomonas syringae van Hall.

Venturia spp. are reported attacking all species of Populus throughout the geographic range of the genus. In some areas, the disease becomes severe, particularly during seasons of wet weather, which favors fungus development and spread.
