temperature under 65 ° degrees Fahrenheit alongside high humidness or other wet conditions are a perfect breeding earth for the mold , which can spread chop-chop .
Its fungal spores travel effectively in water droplets and are carried by air currents and worm . They then germinate on the upper surface of leaves and stem , spreading rapidly and making this a difficult disease to prevent totally .

Symptoms of Downy Mildew
