What symptom is NOT typically associated with apple scab?

The symptom that is not typically associated with apple scab is stunting of plants. Apple scab, caused primarily by the pathogen Venturia inaequalis, manifests mainly through leaf and fruit symptoms. These include scabs on leaves and apples, defoliation, and sometimes cracked or deformed fruit.

Scabbing on the surface of apples is a hallmark sign of the disease, as is the premature dropping of leaves. While these symptoms can contribute to a general decline in plant health, stunting—characterized by a reduction in growth—does not specifically result from apple scab itself. Rather, stunting is more commonly linked to other factors such as nutrient deficiencies or root problems, rather than the direct effects of apple scab infection. This distinction is crucial in diagnosing plant issues effectively.
