    Morphologically green mold can be distinguished as dense white mycelial growth with green patches at random sites on the surface of mushroom pileus. Spores of the fungi are transmitted by mites, flies and growth room workers. Red pepper mite is the insect vector of the disease.

    For its effective management, the hygienic conditions should be promptly maintained inside the growing chamber, all the equipment and worker clothes should be properly decontaminated. Proper sterilization of substrate compost is very necessary for high yield. In case of contamination of substrate it should be properly disposed far away from the growing chamber. Proper ventilation and air filter system should be available across the growing chamber. Insect vector should be kept away from the mushroom growing chamber.
