Abstract
Rot disease is one of the most serious issues causing considerably significantpostharvest losses on rambutan. With the aim to support in finding outeffective control approaches, an investiagation tittled “ Studies on causal agents of postharvest rot diseases on rambutan in Mekong River Delta was carried out on aspects of including isolation, namingnomenclatureand evaluation of culture conditions.on growing and development of isolated fungi. Results indicated that there were seven fungi were recored as causal agents causing postharvest rot diseases on rambutan,i.e. Lasiodiplodia pseudotheobromae, Phomopsis mali, Lasmenia sp., Gliocephalotrichum cylindrosporum, Pestalotiopsis virgatula voucher, Pestalotiopsis clavisporaand Fusarium verticillioides. Two feature rot symptoms (cloudy and black rots) which have caused by these fungim,could be regconized by nakedeye. All these fungi were greownwell on all three culturemedias of, i.e.PDA (potato dextrose agar), PCA (potato carrot agar) and MEA (malt extract agar) in optimum ranges of temperature 25-30oC and pH 6-8. Among the examinated fungi, Lasiodiplodia pseudotheobromae had a wide growing temperature between15to-35oC and Pestalotiopsis virgatula voucher could be grown at high temperature (45oC).
