Abstract
Washings from red pine needles treated with a strain of Pseudomonas fluorescens and a nutrient source remained inhibitory to conidial germination of Gremmeniella abietina for 72 hr. after application of bacteria. In field studies, strains of P. fluorescens were applied to red pine seedlings that were subsequently inoculated with conidia of G. abietina. Disease incidence was lowest when bacteria were applied in a nutrient solution immediately prior to inoculation with conidia. Results suggest that temperature, availability of free water and nutrients affect survival of applied antagonists and subsequent control of G. abietina. Environmental effects on antagonist and pathogen survival and interaction are being modeled.
