Item Effect of yellow vein mosaic virus infection on the phyllosphere microflora of bhendi (Abelmoschus esculentus W. and A.) plants(Kerala Agricultural University, 1974) Potty, V P; Wilson, K IPhyllosphere microflora of yellow vein mosaic virus inoculated and healthy bhendi plants have been studied at different stages of growth. The middle and bottom leaves of infected plants showed significantly lower population of fungi than the corresponding leaves of healthy plants. The bacterial population on the middle leaves of infected plants was significantly higner than that of the healthy. The differences between the actinomycete population on the leaves of healthy and infected plants were not sign-ficant. The middle leaves of infected plants showed significantly higher total microbial population than those of the healthy ones. The differences in microbial population between leaves of healthy and diseased plants is attributed to the changes in host physiology caused by virus infection.Item Effect of yellow vein mosaic virus infection on the phyllosphere microflora of bhendi (Abelmoschus esculentus W And A) plants(Kerala Agricultural University, 1974) Potty, V P; Wilson, K IPhyllosphere microflora of yellow vein mosaic virus inoculated and healthy bhendi plants have been studied at different stages of growth.

Only two varieties namely, Nadiya and Narasapattam were moderately resistant. Six varieties were moderately susceptible and twelve varieties were susceptible. The varieties Bajpai and Seirra-leone were highly susceptible to the disease.Item Use of some newer insecticides for the control of cardamom thrips, Soothrips Cardamomi (Rank)(Kerala Agricultural University, 1977) Wilson, K I; Joseph, D; Rahim, M A; Nair, M R G KItem Cigar-end disease of banana(Kerala Agricultural University, 1980) Susamma Philip; Wilson, K I; Abraham, MItem Deterioration of copra by fungi(Kerala Agricultural University, 1980) Unnikrishnan Nair, P K; Samraj, J; Wilson, K IFungi Aspergiltus niger, Aspergiltus sp., Penicillum sp., Rhizopus, sp., Diplodia sp. and Trichoderma sp. were isolated from copra samples. These fungi grew on copra and caused reduction in oil content under artificial inoculation Except Rhizopus sp. all the organisms grew well in Richard's solution containing coconut oil as carbon source. Trichoderma sp. has not been reported on copra so far.Item Some new host records for Cylindrocladium Quinqueseptatum from India(Kerala Agricultural University, 1982) Sulochana, K K; Wilson, K I; Chandrasekharan Nair, MItem Agave Americana - a new host of Phytophthora palmivora (Butler) butler(Kerala Agricultural University, 1987) Beena, S; Ravi, S; Wilson, K I; Estellitta, SItem Growth of cylindrocladium quinqueseptajum on different oil incorporated medfa(Kerala Agricultural University, 1983) Sulochana, K K; Wilson, K I; Chandrasekharan Nair, MItem Fungicidal control of fruit rot of chilli caused by colletotrichum capsici (Syd.) Butl. & Bisby(Kerala Agricultural University, 1992) Sulochana, K K; Rajagopalan, B; Wilson, K I
