Item Colletotrichum gloeosporioides causing inflorescence dieback, button shedding and nut rot of betel nut palm(2007-02-08) Saraswathy, N.; Koti Reddy, M.; Radhakrishnan Nair, R.Item Detection of Ganoderma lucidum in betelnut by the fluorescent antibody technique(2007-02-08) Koti Reddy, M.; Ananthanarayanan, T.V.Item Diseases of arecanut in India - A review and further considerations(2007-02-08) Koti Reddy, M.; Saraswathy, N.; Chandra Mohanan, R.The major diseases affecting arecanut in India are: koleroga or mahali, anabe, yellow leaf disease, inflorescence die-back, and button shedding. Among the less serious diseases, the bud-rot, bacterial leaf stripe, stem breaking, seedling diseases, and infection of processed arecanuts, occurls at times in serious proportions in some places and cause considerable damage. Over 40 pathogenic and non-pathogenic forms have been recorded in India. The work done on them except the storage infections is reviewed here with suggestions for future lines of work.Item Distribution of microflora population in the rhizosphere of arecanut(2007-02-08) Bopaiah, B.M.; Koti Reddy, M.Item Effect of certain fungicides on Phytophthora palmivora of cocoa(2007-02-08) Koti Reddy, M.; Mohan, R.C.Item Evaluation of certain fungicides against the die-back disease of areca inflorescence(2007-02) Saraswathy, N.; Koti Reddy, M.; Radhakrishnan Nair, R.Button shedding preceded by die-back of inflorescence is a severe problem in the areca plantations. Out of 13 fungicides tested in vitro, benomyl (0-1%), captan (0-25%), thiram (0-25%), and a phenyl mercury urea formulation (0 -1%) were highly fungicidal to the mycelial growth of Colleto-trichum gloeosporioides, the casual agent of the disease. Field trials carried out with -even fungicides showed that DMOC (0-1%), heptaene antibiotic (50ppm) + CuSO4 (50ppm), and Zineb (0-4%) in that order, were effective in controlling the malady.Item Evaluation of certain fungicides in soil against Ganoderma lucidum (Leys) Karst pathogenic on arecanut(2007-02) Koti Reddy, M.; Saraswathy, N.Item Fungal infection of stored arecanuts(2007-02) Nambiar, K.K.N.; Koti Reddy, M.The betel nuts (Areca catechu L.) are infected by various fungi and bacteria during drying and storage. Most of the fungi gain access to the nuts through soil contact. The nuts are predisposed to infection by fungi when rainfall, high humidity, and favourable temperature are prevalent during drying and storage. The infection can be prevented or minimised by eliminating soil contact at the time of harvest and drying, by quick drying of nuts using mechanical driers or cement floors, and storing nuts in polythene-lined gunny bags or air tight store rooms.Item Koleroga of Arecanut(2007-02) Koti Reddy, M.; Anandaraj, M.Item Occurrence of Pod Rot of Cacao Caused by Colletotrichum Gloeosporioides in India(2007-02) Koti Reddy, M.; Chandra Mohanan, R.Pod rot of cacao (Theobroma cacao L.) caused by Colletotrichum gloeosporioides was observed in severe form in three southern states of India. The fungus was isolated in pure form from rotting pods and its pathogenicity was proved on Forestero cacao pods by artificial inoculation. The symptoms of the disease are described. The pathogen caused more damage to cherelles and immature pods. This is the first reported occurrence of pod rot of cacao caused by C. gloeosporioides from India.Item Phenols and oxidase in the roots of healthy and Anabe affected arecanut palms(2007-02) Koti Reddy, M.; Saraswathy, N.; Sampath Kumar, S.N.Item Relative efficacy of fungicides in vitro against Botryodiplodia theobromae causing charcoal pod rot of cacao(1979) Chandra Mohan, R.; Koti Reddy, M.Item Yellow Leaf Disease of Arecanut : Recommendations of Various Committees(1976) Koti Reddy, M.
