Treatment and control
General tips
Pick off affected part of the plant and reduce humidity by increasing space between plants and air movement. Burn plants that are severely affected. Avoid over-feeding with a high nitrogen fertiliser as this encourages soft lush growth that is more susceptible to attack. No fungicide treatments are available to amateur gardeners.
