Item Bacterial wilt of cassava (Manihot esculento crantz.) in Kerala(Kerala Agricultural University, 1975) Paily, P V; Rema devi, L; Menon, M RItem Effect of fungicides and silica in the control of sheath blight disease of rice caused by Corticium Sasakii (Shiriai)(Kerala Agricultural University, 1981) Mathai, G; Paily, P V; Menon, M RResults of field experiments conducted at Vellayani, Kerala during 1974 indicated that Hinosan was significantly superior in reducing sheath blight disease intensity and in increasing the yield of rice due to better disease control. Application of silioa (250 and 500 kg/ha) had significant effect in reducting the disease intensity on the 75th day of sowing. Crude silica content in the plant was high at the 40th and 80th day of sowing but was low on the 60th day. Positive correlation was observed between the amount of applied silica and the crude silica content of plant.Item Symptomatology and etiology of bacterial blight of cassava (Manihot Esculenta Crantz)(Kerala Agricultural University, 1981) Raveendran Nair, R; Paily, P V; Menon, M RThe bacterial blight of cassava was observed in Trivandrum, Kerala, during 1975 and since then its sporadic incidence was reported form other regions also. The symptoms manifested as blighting of leaves, defoliation, die-back, necrosis of stem, decay of roots (tubers) and wilting of plants. The causative bacterium was isolated and its pathogenicity established by artificial inoculation. Based on the morphological, physiological and biochemical characters of the bacterium and the symptoms produced by it, the pathogen causing the blight of cassava was identified as Xanthomonas manihotis fArthaud-Berthet) Starr.Item Physiology of parasitism of Pythium Aphanidermatum (Edson) fitz. inciting soft-rot of ginger(Zingiber officinale rose)(Kerala Agricultural University, 1982) Indrasenan, G; Paily, P VA study on production of pectic enzymes in five liquid media was made. Pythium aphanidermatum (Edson) Fitz. was found capable of elaborating various pectic enzymes in vitro and in vivo, Estimation of pectic enzymes like pectin methyl esterase (PME), exopolygalacturonase (Exo-PG), endopolygalacturonase (Endo-PG) polygalacturonase transeliminase (PGTE) and macerating activity on potato discs were done in five liquid media on four different days and observed that the rate of production of these enzymes by P. aphanidermatum varied with different media and age of the culture, the maximum production being noted in Conn's medium on the 3rd day. P.aphanidetmatum(Edson)Fitz. was found to produce various pectic enzymes as judged by the in vitro and in vivo studies which play a predominant role in bringing about the tissue degradation and the eventual pathogenesis on the host.Item Studies on the soft rot of ginger (Zingiber officinale rose) caused by Pythium aphanidermatum (Edson) Fitz.(Kerala Agricultural University, 1973) Indrasenan, G; Paily, P VItem Observation on the aerial application of an oil based fungicide against the leaf rot disease of the coconut palm(Kerala Agricultural University, Vellanikara, 1966) Sam Raj, J; Paily, P V; Abi, Cheeran
