Often, potassium deficiency symptoms first appear on older (lower) leaves because potassium is a mobile nutrient, meaning that a plant can allocate potassium to younger leaves ...

Once on the leaves, the spores germinate and penetrate through the stoma. [2] The subsequent infection causes chlorosis of the leaves in localized yellow spots. As the season continues into summer, apothecia begin to form, giving rise to brown-black leaf lesions that resemble spots of tar. [2] Leaves retain their yellow border from the initial ...
The spots appear to have rings of brown with a purple margin, thus giving it its frogeye appearance. The spots can then produce pycnidia which can separate this species of fungus from other possible leaf fungi. [1] Canker. On twigs, branches and trunks B. obtusa can infect where there has been a winter injury or fire blight cankers. Slightly ...
