Item Cultural, morphological and pathogenicity studies on some Phytophthora isolates from cocoa in Sri Lanka(University of Peradeniya. Peradeniya, 1995) Seneviratne, M.A.P.K.; Liyanage, A. De S.; Adikaram, N.K.B.Item A model for predicting the BlACK POD development in cacao under laboratory conditions(1995) Senavirathne, M.A.P.K.; Liyanage, A. De S.; Adikaram, N.K.B.Five cacao varieties were screened for 'Black Pod' development by Phytophthora in semimature, harvested pods. The size of lesions on pods of each variety was measured on 5 consecutive days. The results showed that the rate of lesion development could be fitted to an exponential curve. This curve may be useful for predicting the lesion size within a 5 day period.Item Occurrence of leaf blotch disease (Botryosphaeria sp.) in Ficus relegiosa in Sri Lanka(2009) Maharachchikumbura, S.S.N.; Adikaram, N.K.B.Item A phenetic analysis of Colletotrichum gloeosporioides isolates from selected host plants(2009) Gunawardhana, P.L.T.; Senevirathna, A.M.W.K.; Adikaram, N.K.B.; Yakandawala, D.M.D.Item Some biochemical factors underlying the differential susceptibility of two pineapple cultivars to internal browning disorder(University of Peradeniya. Peradeniya, 2005) Weerahewa, D.; Adikaram, N.K.B.Item A survey of post-harvest losses in some fruits and vegetables and the fungi associated with them(University of Peradeniya. Peradeniya, 1986-87) Adikaram, N.K.B.A survey was conducted of the post-harvet losses in some fruits and vegetables in the Central Province of Sri Lanka where 35 fruit and vegetable stalls were visited and imformation on storage practices and losses in various commodities gathered. The figures showed that losses in the range of 5-25perc. are commonplace in most commodities. Shelf life in many of these did not exceed 6-7 days. Thirty seven species of fungi belonging to 13 genera were isolated from the diseased fruit and vegetable samples collected in this survey. According to the nature of the infection and subsequent rotting these fungi could be divided in to two major categories:(1) those fungi that invade overripe fruit through mechanical wounds and cause latent infections in the immature fruits and develop rotting only when the fruit is ripened.
