Abstract
Polianthes tuberosa L.(Rajigandha) is an important medicinal plant possessing diuretic emetic and antigonorrhoeic properties.Plants of Ptuberosa growing in pots were found suffering from a leaf spot disease.Oval to elongated spots were produced throughout the leaf blade.The spots remained broader in the center and pointed at the ends.Light brown spots are surrounded by dark brown spots. Spots may also coalesce to form large irregular spots.Isolation from the disease tissue yield a species of Fusarium.Pathogenicity test was proved to be positive when carried out by spray inoculation on healthy potted plants of P tuberosa, positive, On the bases of cultural characters and morphology of vegetative and reproductive bodies,the isolated species from Ptuberosa was identified as Fusarium solani.Search of the available literature revealed that P tuberose is a new host for F solani which is being first reported from Bahraich district (U.P.)
