PERPETUATION AND EPIDEMIOLOGY OF POWDERY MILDEW OF MANGO |
| Author: | J.H. Gupta |
| Abstract:
Powdery mildew of mango was found to perpetuate through older infected mango leaves and intact green malformed inflorescences in the form of mycelium and conidia or dormant mycelium. Maximum infection of the host occurred at 26°C and 100 per cent RH. However, the fungus could cause infection at 15 to 32°C and 15.5 to 100 per cent RH. It was observed that atmospheric temperature was most important factor for onset and epidemic development of the disease under field conditions. The temperature range of 11–14°C (minimum) and 17–31°C (maximum) along with moderate relative humidity (64–72 per cent) was most congenial for the development of powdery mildew of mango. Rainfall did not play any significant role on appearance and disease development, but dry weather favoured the development of the disease. | |
