Cercospora Leaf Spot

Causal Agent: (fungus ‑ Cercospora citrullina)

Leaf spots have a dark brown center and a yellow halo [wmp16.jpg]. Infected leaves are first observed at the crown of the plant.  When the disease is severe, foliage loss will  restrict fruit development and result in sunburn of fruit. The fungus is controlled with fungicides. Applications should begin soon after runner development.
