Studies on sources of nematodes inoculum showed that the most potential sources of nematode dissemination in Agaricus bisporus were wheat straw, chicken manure and spent compost often used as casing material. Since chicken manure is not used in Calocybe indica nematodes were mainly disseminated in this mushroom through other two means. Besides, FYM, loam and platform soil also acted as source of nematode inoculum. Dipteran flies hovering in the farms also disseminated nematodes from one bed/room to other in both the cases. Interestingly, sporophores of Calocybe indica were found to harbour more nematodes as compared to that of Agaricus bisporus.
