Abstract

Mushrooms are edible fungi. Milky mushroom (Calocybe indica) fits well under summer months conditions because of its ability to grow at temperature above 30°C. The green mould due to Trichoderma harzianum is of common occurrence in milky mushroom cultivation and causing losses from 63-65%. The disease characterized by initially white to grayish mycelium appear on substrate and on casing surface that resembles with the mushroom mycelial and later on mycelium mat turns to dark green color due to heavy spoliation of causal agent which is a peculiar symptom of the disease. The green mould incidence recorded varies from 0 to 26 % and maximum being in the Sonipat district (26.0 %), and no disease was recorded in Fatehabad district. The average disease incidence in Haryana recorded during 2014 was 14.8 per cent and approx similar pattern of disease prevalence (13.8 per cent) was observed during 2015.

Abstract

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.
