Abstract: Histopathology of soybean rust (Phakopsora pachyrhizi Sydow) and anthurium leaf blight (Xanthomonas campestris pv. Dieffenbachiae) were studied. The stage uredia were found in soybean rust infected sample containing urediospores of round to oval shaped with yellowish brown or hyaline in colour. Disintegration of plant cells, presence of bacterial cells and clogging of xylem vessels were observed in the anthurium leaf blight infected samples.
