The aim of the laboratory experiment was the isolation of fungi colonized potato tubers directly (immediately) after harvest and after 5-month storage. 67 potato tubers samples collected in 1998 and 1999 from the areas of province Warmia and Mazury were examined. The occurrence of 36 and 46 species were confirmed on analyzed tubers after harvest and storage, respectively. The most frequent species which occurred on tubers were: <i>Alternaria alternata</i> (9,4%), <i>Colletotrichum cocco- des</i> (12,6%), <i>Rhizoctonia solani</i> (7,4%) and fungi from <i>Fusarium genera</i> (8,7%).This fungi, except <i>Rhizoctonia solani</i>, more often colonized potato tubers afier storage. Among saprofitic fungi most frequent were: <i>Epicoccum</i> (3,4%), <i>Mortierella</i> (3,1%), <i>Mucor</i>(6,0%), <i>Penicillium</i> (17,0%), <i>Rhizopus</i> (7,1%) and <i>Trichoderma</i> (12,9%). More colonies of fungi were obtained from potato tubers analyzed after harvest. Remaining fungi were more frequently isolated after storage.

Post harvest management of potato under sub-tropical conditions in Jammu division was studied. The losses due to poor handling and storage are reported to be in between 40 and 50%. The physiological and pathological causes observed before and during storage on potato crop revealed that 51.51% of respondents observed bruises on tubers followed by rooting (48.00%), chilling injury (44.89%), enlarged lenticels (42.67%) and sprouting up to 40.89%.

And Storage

Potato (Solanum tuberosum L.) is a tuberous crop from the Sola-naceae family which is a source of starch and food to many in Nige-ria, however, its production is being hampered in field and storage by bacterial pathogen which causes rot of the stored tubers. To this end, the study aimed at screening potatoes from different stores within Ibadan for the evaluation and diversity of bacteria pathogens responsible for rot in potatoes. Damaged stored potato samples were collected from different locations in Ibadan for studies, these samples were isolated for bacterial pathogen and characterized bio-chemically and observed under the microscope for identification. Three genera of bacteria were observed to be responsible for potato rot in the study and they include Pectobacterium carotovorum, Pseu-domonas syringae and Ralstonia solanacearum. Of all the isolated bacteria, Pectobacterium carotovorum has the highest occurrence with a frequency of 60%, while Pseudomonas syringae has a fre-quency of 33% and Ralstonia solanacearum has a frequency of 27%. The pathogenicity of the isolates were tested and this revealed that Pectobacterium carotovorum is the most virulent with a severity score of 4.3, while Ralstonia solanacearum follows with a score of 3.3 and a score of 2.7 was recorded for Pseudomonas syringae, while the control had a score of 0. The diversity and differences shown in the isolated bacteria indicated that potato rot is a serious disease which is caused by different bacteria and need an integrated ap-proach for its control from the field of harvesting to the storage house.
