It penetrates the fruitlet through the vascular bundles beneath the calyx (the crown at the top of the fruit) and remains latent, or dormant, within the fruit. Symptoms only become visible much later as the fruit ripens and its sugar content increases 2.<\/p><p>This colonization pattern explains why seemingly healthy fruits can develop rot from the inside out during ripening and storage. Fungal populations shift as the fruit matures, with Alternaria and Cladosporium being dominant in early stages, while Aspergillus becomes most abundant in the final ripe (Tamar) stage.<\/p><h2><strong>Symptom Detection<\/strong><\/h2><ul><li><strong>Internal Rots (e.g., Black Mould):<\/strong> <br \/>The primary symptom is a mass of black, powdery spores inside the fruit.

Although trained workers in packinghouses can sort out some infected fruit, detection is difficult, and diseased fruits often reach the consumer.<br \/><br \/><\/li><li><strong>External Rots (e.g., Alternaria Rot):<\/strong> <br \/>These appear as superficial, firm, dark brown or black spots and lesions on the fruit&#8217;s skin.
