How does weather Affect the spread of plant fungal diseases?

Weather significantly influences the spread of plant fungal diseases by creating favorable conditions for fungal growth and reproduction. High humidity and temperatures, particularly in the range of 60-80°F (15-27°C), promote spore germination and infection. Additionally, rainfall and dew can facilitate spore dispersal and increase moisture on plant surfaces, which is essential for many fungi to thrive. Conversely, dry conditions can hinder fungal spread by reducing moisture levels and limiting the survival of fungal spores.
