Main symptoms

Monographella cucumerina produces small, white, elongated to diamond-shaped lesions developing on the leaf blades and veins (Figures 1 to 3), petioles (Figure 4), twigs, and peduncles (Figure 5) of fruits.

 
Lesions on fruits are also small, rather circular to irregular, white or even metallic (bronze to silver) (Figures 6 and 7). As they evolve, they merge and make the surface of the fruits more or less dry and speckled.
