Description Capsule rot ('Azhukal') and leaf blight are two major Phytophthora diseases of small cardamom (Elettaria cardamomum Maton). Variability among the Phytophthora isolates causing these diseases were studied using Phytophthora cultures isolated from rot affected plant parts such as capsules, rhizomes, leaf and also froth blight affected leaves collected from different locations. Detailed studies on growth of these cultures in different media and at different temperatures showed significant difference between these isolates. P. meadii did not cause any pigmentation in casein hydrolysate tyrosine agar (Timmer's medium) and the fungus did not grow at high temperature while P. nicotianae var. nicotianae showed chocolate reddish brown pigmentation in casein hy¬drolysate tyrosine agar and did grew at high temperature. Therefore pigmentation in casein hydrolysate tyrosine agar and growth at high temperature were found ideal for differentiating Phytophthora isolates infecting cardamom.
