- Observation Powdery mildew conidia germinated at 10–35°C, with limited germination at the range endpoints.
- Intervention effect Below the optimum temperature, powdery mildew mycelial development was delayed.
- Intervention effect Below the optimum temperature, first conidiophore appearance was delayed.
- Observation Conidiation occurred at 15–25°C and was most intense at 20–25°C.
- Intervention effect Mycelium development and conidiation were greatest near 60 μmol/m2 per second of light.
- Intervention effect Lower light intensities delayed pathogen development.
- Intervention effect Darkness completely inhibited conidiation.
- Intervention effect A 24-hour dark period after inoculation did not stimulate later mycelium development.
- Intervention effect Twelve hours of light followed by darkness delayed mycelium development.
- Intervention effect Twelve hours of light followed by darkness fully restricted conidiation.
- Intervention effect Four days of darkness followed by normal photoperiod accelerated mycelium development.
- Intervention effect Covering only an inoculated leaf gave intensive mycelial development and slight later sporulation.
