Effect of Pseudomonas spp. on inoculation of young plants of Fraxinus excelsior stem with Diplodia mutila

Bacteria Pseudomonas aureofaciens, P. cepacia and P. fluorescens biovar I was tested againts fungus Diplodia mutila on stems of 2-year-old plants of European ash in greenhouse experiments. The interaction of bacteria and fungus was assessed on the base of length of necrotic lesions, caused by D. mutila, extended from point of inoculation. The strongest antagonistic effect was noted in the case of P. aureofaciens. Additional key words: bacteria, fungus, antagonism, in vivo Address: K.
