Radhakrishnan Nair 100-103http://hdl.handle.net/123456789/4923The root region microflora of disease early, disease advanced and apparently healthy palms from yellow leaf disease affected areas and healthy palms from disease free areas of Chikmagalur, Shimoga and Dakshina Kannada districts of Karnataka State were enumerated. The bacterial population was more in the disease affected area as compared to healthy area. But the fungal flora were less in the disease affected area of Aranthodu (Sullia) and Sagar (Shimoga) as compared to the disease free area. Qualitatively the microflora did not differ much in the healthy and disease affected palms and no selective proliferation of micro-organisms occurred in either healthy or disease affected palms. The study has indicated the possible involvement of a phytotoxin in the disease.enArticle
