Acorus calamus L. an aromatic rhizomatous herb plant has a long history as a medicine which is often used as stimulant, mild tonic, carminative, diaphoretic, expectorant, hypertensive, sedative and also used in the treatment of arthritis, neuralgia, diarrhea, dyspepsia, hair loss and other disorder. Among the several constraints in productivity of this medicinal plant, abiotic stress relating to disease is the major one. The rust disease caused by Uromyces spp is one of the important disease causing huge losses of the plant and is greatly influenced by the abiotic factors. It has been observed from the present study that the rust of A. calamus began to appear during March in the field and its intensity increased gradually up to September. Significant positive correlation was found between maximum temperature, minimum temperature, maximum relative humidity, rainfall and disease intensity during 2015. The multiple regression equation also reveals that the weather factor all together accounted for more than 99.1 % variation in diseases severity.
