Description
Summary:Blast of pear caused by Pseudomonas syringae pv. syringae is one of the bacterial disease that limit pear production throughout the world. Symptoms are characterized by blast of buds and blossoms wich causes significant loss of fruit production, and necrotic spots on leaves or fruits. Control of bacterial blast of pear with chemicals is difficult and is based on copper compounds and antibiontics. However, its use is limited by the low efficacy, phytotoxicity to the plant or emerging resistance of the pathogen. The activity of several phosphonates (fosetil-Al, potassium phosphonate, etephon and fosfomycin) for control of P. syringae pv. syringae infection on pear was determined in this work, and laboratory models for studying P. syringae pv. syringae-pear interaction were developed
