What is early blight disease?

Early blight is primarily a disease of stressed or senescing plants. Symptoms appear first on the oldest foliage. Affected leaves develop circular to angular dark brown lesions 0.12 to 0.16 inch (3–4 mm) in diameter. Concentric rings often form in lesions to produce characteristic target-board effect.

What is red rust disease?

Red rust, caused by Puccinia helianthi, is an autoecious rust meaning it produces all its spore stages on sunflower; there are no alternate hosts. Teliospores germinate to produce basidiospores that infect the leaves resulting in the formation of pycnia within which are produced pycniospores and receptive hyphae.
