Internal (probably physiological disorders), and ii) External (probably infectious diseases). Brown to black irregularly shaped spots develop on leaves. Intensive production during the first half of the twentieth century resulted in devastating diseases, such as those caused by the fungi Ascochyta, Septoria, and Verticillium, which severely threatened the chrysanthemum industry, but are no longer problems because of the widespread use of fungicides and the clean stock programs employed by the key producers.

Now-a-days, micronutrients especially zinc Small dark brown to black spots on lower leaves enlarge and become irregular in shape. Although silicon is not an indispensable element for the growth and development of higher plants, according to Epstein (2009), under stress conditions additional treatment with silicon may cause a big difference in their performance.
