**2. Enhancement of shelf life of button mushroom**

Effect of dipping treatment on the quality and shelf life of the button mushroom (*Agaricus bisporus*) was studied at Mushroom Research Laboratory (AICRP on Mushroom) of the Department of Plant Pathology, Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur for two years. The fresh fruiting body of four varieties of button mushroom, S 649, SSI 4035, Pant 31 and NCS 100 of size 25 2 cm or available size fruit bodies were washed in solutions containing EDTA

at 75, 125, 200 ppm & 0.05% of potassium meta bisulfate (KMS) concentration. Thereafter, the fruit bodies were taken out, put in blotter paper to remove moisture and stored at ambient temperature and refrigerated temperature for different durations after packaging in 100 gauge polypropylene bags.
