The number of epiphytic Pseudomonas syringae isolated from maple twigs and leaves between July 1985 and September 1986 was erratic (undetectable to 10(5) cfu/g), whereas the number isolated from pear was more stable and often higher (10(3) to 10(6) cfu/g). P. syringae was isolated consistently (abou...
