There was an accumulation of calcium and magnesium in plants inoculated with the pathogen, while potassium and phosphorus recorded a reduction after infection.ArticleItem Open Access Changes in the nitrogen and sugar content of rice infected with Corticium Sasakii (Shirai) Matsumoto(Kerala Agricultural University, 1980) Padmakumari, G; Menon, M R; Remadevi, l; KAUChanges in the nitrogen and sugar content of rice plants after infection by Corticium sasakii (Shirai) Matsumoto were investigated. The infection by the fungus reduced the total nitrogen content. The amino nitrogen content increased significantly due to infection. The sugar content also showed significant reduction as compared to healthy plants.ArticleItem Open Access Changes in the nitrogen and sugar content of rice infected with Corticium Sasakii (shirai) Matsumoto(Kerala Agricultural University, 1980) Padmakumari, G; Menon, M R; Remadevi, l; KAUChanges in the nitrogen and sugar content of rice plants after infection by Corticium sasakii (Shirai) Matsumoto were investigated. The infection by the fungus reduced the total nitrogen content. The amino nitrogen content increased significantly due to infection. The sugar content also showed significant reduction as compared to healthy plants.ArticleItem Open Access Control of phytophthora disease of cardamom(Kerala Agricultural University, 1973) Menon, M R; Sajoo, B V; Ramakrishnan, G K; Rema Devi, L; KAUArticleItem Open Access Effect of different sources of carbon and nitrogen and tissue media on the cultural characters and pathogenicity of helminthosporium oryzae bredade haan(Kerala Agricultural University, 1970) Sreedharan, A; Menon, M R; KAUArticleItem Open Access 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 R; KAUResults 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.ArticleItem Open Access In vitro effects of certain herbicide formulations on Corticium Sasakii (Shirai) matsumoto(Kerala Agricultural University, 1978) Varma, A S; Peethambaran, C K; Balakrishnan, S; Menon, M R; KAUArticleItem Open Access Leaf spot disease of Artocarpus incisa L.(Kerala Agricultural University, 1970) Balakrishnan, S.; Menon, M R; KAUArticleItem Open Access Occurrence of triste2A and greening diseases of citrus in Kerala(Kerala Agricultural University, 1970) Nariani, T K; Viswanath, S M; Menon, M R; KAUArticleItem Open Access Symptomatology and etiology of bacterial blight of cassava (Manihot Esculenta Crantz)(Kerala Agricultural University, 1981) Raveendran Nair, R; Paily, P V; Menon, M R; KAUThe 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.ArticleItem Open Access Transmission of Pseudomonas Solanacearum through tomato seeds(Kerala Agricultural University, 1980) Rema Devi, L; Menon, M R; KAU
