What is Passionfruit Fungal Spot

This is a serious fungal disease which affects leaves, stems and fruit. It occurs mainly in spring and early summer.

 

Symptoms

On leaves, small brown spots appear first. These enlarge, develop a lighter-coloured central area, and become irregular or angular in shape. On fruit, spots first appear as pinpricks, which enlarge into sunken circular lesions with brownish centres. Spots can develop into extensive superficial lesions causing premature drop and fruit decay.
