Unlike most foliar fungi, powdery mildew thrives in dry yet humid conditions and is highly sensitive to climatic variables such as temperature, relative humidity (RH), and sunshine. This review synthesizes published studies on the relationship between climate and powdery mildew incidence across various agro climatic zones, with special reference to India. The results show that morning RH above 60%, moderate temperature (18–28°C), and low rainfall favor conidial germination and disease severity. Extremely high RH (>90%) or rainfall tends to inhibit disease development due to spore lysis or physical wash off. Studies also show variability among host species and regional responses.
