Koch's Postulates

Madar (Calotropis gigantea) is a medicinally important wild shrub native to India. The seed floss is used for furniture stuffing and the bark for nets and twine. In early 2005, we observed a leaf spot epidemic of madar growing on wasteland sites near the Sikar district of Rajasthan, India. Koch's Postulates were completed. This is the first record of the disease from the Sikar district of the Rajasthan state of India. Accepted for publication 6 February 2009. Published 31 March 2009.
