Calotropis procera (Aiton) W.T. Aiton. (Asclepiadaceae) commonly known as Madar or’Aak’ is a medicinally important wild shrub native to India useful in treatment of a number of illnesses including dysentery,intermittent fevers, cold, cough, and asthma. We observed a serious leaf spot disease of madar growing on wasteland sites near about AUH in the Panchgaon, Manesar- Gurgaon (Haryana) in year onward 2014. In January and February 2017, we observed this leaf spot to be very prevalent or on almost all plants in the vicinity. Disease incidence was greater than 90% and caused extensive abscission of leaves. Symptoms on infected leaves were first observed in end of October to November of each year as small, circular spots with large yellow to dark brown halos on both sides of the lower and upper leaves. The spots gradually enlarged in size. Soon they became irregular in shape or remained circular with concentric rings or zones. This is a new record from Aravali Hills near AUH at Panchgaon, Gurgaon Haryana.
