Effect of hot water treatment on post-harvest diseases of guava (Psidium guajava L.) fruits.

Fruits harvested in Jaipur were inoculated separately with Botryodiplodia theobromae, Colletotrichum gloeosporioides [Glomerella cingulata], Pestalotiopsis versicolor, Phomopsis psidii and Rhizopus arrhizus. After 24 h the fruits were dipped in hot water at 40, 45 and 50 deg C for 5 min and incubated at 25 plus or minus 1 deg and 90% RH. The severity of rot was recorded after 4 and 8 d. There was a steady decrease in the severity of rots with rise in temp. of the treatment; severity was significantly decreased when the fruits were treated with hot water at 50 deg C.
