The milky mushroom is gaining popularity among the traditional button mushroom growers in the India as alternate crop during summer months, but green mould disease caused by T. harzianum is becoming a limiting factor for its popularization among the mushroom growers. Physiology of both pathogen (T. harzianum) and milky mushroom (C. indica) was standardized and found that though C. indica can grow at wide range of temperatures and pH but optimum growth was observed at 30±1˚C and pH 6.0. Similarly the optimum growth of T. harzianum was observed and found that it was at temperature 25±1˚C and pH 6.5. The effect of temperature and pH on interaction of C. indica with T. harzianum also was observed and found that minimum inhibition of C. indica by T. harzianum was observed at temperature 30±1˚C and pH 6.0.
