Pseudomonas phaseolicola was present in bean leaves exhibiting chlorotic symptoms. Isolation of the pathogen from these leaves depended upon the technique employed. Pseudomonas phaseolicola was isolated from 39 of 40 leaves with an infiltration-centrifugation technique, whereas it was detected in only 16 of 40 leaves using a comminution technique, and then only in small numbers.
