Abstract

Studies were conducted for two consecutive years on incidence of post-harvest rots of kinnow fruits and economic losses inflicted by them in Sriganganagar district situated in North-West part of Rajasthan. Surveys of retail fruit market revealed nearly 6 per cent incidence of post-harvest rots fruit rots. Seven rots were encountered during the surveys, viz., core rot {Alternaria alternata (Fr.) Keissler}, stem-end rot (Botryodiplodia theobromae Pat.), sour rot (Geotrichum candidum Link.), green mould rot (Penicillium digitatum Sacc.), blue mould rot (P. italicum Wehmer), black rot (Aspergillus niger Van Tieghem) and bitter rot (Colletotrichum gloeosporioides Penz and Sacc.). Among these rots, core rot, stem-end rot, sour rot, green mould rot and blue mould rot were found as major rots sharing 85 to 90 per cent of the total post-harvest rotting. Maximum economic loss of Rs. 20872 was induced by blue mould rot out of the total value of the fruits (Rs. 1583518) which is 1.32 per cent of the total during the crop season. The overall loss due to these five major rots was of Rs. 83305 which is 5.26 per cent of the total value of the fruits Rs. 1583518.
