Rajnigandha a new host of Fusarium sp. from Bahraich-A New Report

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.)
