Leaf spot disease of sapota causes scattered spots over the leaves. however I have not observed any spots or damage on the fruits. anybody working on the pathogen on sapodilla? could you tell me how exactly yield damage takes place due to the disease.
Dear Kamesh
The reduction of yield caused by Sapota leaf spot disease probably due to reduction of leaf area caused by pathogen and as a result effect photosynthesis process.
Best Regard

The fungal leaf spots will rduce the total photosynthetic area of the leaves and if in severe form will lead to defoliation. As a result the plant will suffer by spending more energy to produce fresh leaves or less photosysnthates will be available for the plant
