Influence of temperature and humidity on the growth and development of Colletotrichum gloeosporioides and Diplodia natalensis causing postharvest fruit rot of mango.

The effects of temperature, rainfall, and relative humidity (RH) on the incidence of C. gloeosporioides [Glomerella cingulata] and D. natalensis [Botryodiplodia theobromae] causing postharvest rot of mango fruits was studied by artificial inoculation. In vitro studies showed that growth of G. cingulata was maximum at 28 deg C and 70% RH. Growth of B. theobromae in vitro was maximum at 32 deg , with good mycelial growth at all RH levels between 60 and 100%. The incidence of G. cingulata in vivo was favoured by temperatures ranging from 34.2 to 34.27 deg and 86.32 to 87.2% RH, while incidence of B. theobromae was favoured by temperatures ranging from 33.5 to 36.2 deg and 84.32 to 86.6% RH. It is concluded that the incidence of anthracnose on mango fruit (caused by G. cingulata) increases at temperatures between 28 and 34.27 deg and 70-87.2% RH, while the incidence of stem end rot (caused by B. theobromae) increases at temperatures between 32 and 36.2 deg and 84.23 -100% RH.
