Mulberry trees (Morus spp.) in Australia are susceptible to several diseases that can impact their health and productivity. One prevalent issue is Mulberry Leaf Spot, caused by the fungus Phloeospora maculans. This disease manifests as small dark spots on leaves in early spring, which enlarge over time, developing white centers with dark brown margins. Severe infections can lead to premature defoliation, stressing the tree and reducing photosynthesis.
Another concern is Bacterial Blight (Pseudomonas syringae), which can cause similar defoliation and may occur concurrently with fungal infections. Environmental factors, such as excessive nitrogen, can also affect mulberry trees by promoting leaf growth over fru...

Another concern is Bacterial Blight (Pseudomonas syringae), which can cause similar defoliation and may occur concurrently with fungal infections. Environmental factors, such as excessive nitrogen, can also affect mulberry trees by promoting leaf growth over fruit production. Implementing good hygiene practices, like removing fallen leaves and ensuring proper air circulation, is essential for disease management. For fungal infections, treatments such as microinjections with appropriate fungicides can provide effective control.
