Publication Date : 02/01/2016
A hitherto unreported leaf blight disease of Palak caused by the pathogen Rhizoctonia solani was noticed in the crop museum at College of Agriculture, Vellayani, Trivandrum, Kerala in the winter sown crop. The symptoms appeared as irregular white to creamy blighted areas on leaves which later became papery and got withered off leaving shot holes. Microscopic examination revealed the presence of both the anamorph (R. solani) and the teliomorph (Thanetephorus cucumeris) on the diseased tissues. The basidia measured 7.0 - 10.2 X 4.4 - 6.9 µm and the basidiospoes measured 4.2 – 8.0 X 3.4 – 5.7 µm.
