Abstract/ Executive Summary:

In Bangladesh, the most common and widely damaging disease of banana is panama caused by Fusarium oxysporum f. sp. cubense (FOC). The survey area was covered during 2017-18 and 2018-19 at Bogura, Rangpur, Faridpur, Jashore and Cumilla only with the objectives to collect the isolates, purify and preservation of the panama causing fungus for characterization in banana production. Panama disease was found in the every area surveyed. Incidence of panama disease ranged from (5-90%). The highest disease incidence (90%) was found in Chapa at Chupinagar, Shahjahanpur, Bogura (24⁰77'04"N,89⁰50'45"E) and the lowest disease incidence (5%)was recorded in Sabri/Anupom and Plantain varieties at Gabtoli, Bogura (24⁰51' 54.061"N, 89⁰24' 57.306"E).

Keywords: Banana, Anaji, Sabri/Anupam, Chapa, Biche kola, Doa, Malbhog, Chinichampa, Homai

Location: Bogura, Rangpur, Faridpur, Jashore and Cumilla district, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Banana

Objectives:

To collect the isolates, purify and preservation of the panama causing fungus Fusarium oxysporum f. sp. cubense for characterization in banana production.

Methodology:

Fusarium wilt of banana caused by Fusarium oxysporum f.sp. cubense. From 72 fields, around three hundred symptomatic samples of Fusarium wilt (Fusarium oxysporum f. sp. cubense) of banana have been collected from different regions of Bangladesh. The area covered during 2017-18 and 2018-19 at Bogura, Rangpur, Faridpur, Jashore and Cumilla districts only. There were eight varieties were observed during the survey program such as, Anaji, Sabri/Anupam, Chapa, Biche kola, Doa, Malbhog, Chinichampa and Homai. Mortality of the plant due to panama was counted from the existing orchards by observing visible symptom and by asking the farmers about the plants and their mortality. Infected plant symptoms collected, took in the laboratory and investigated. Pathogen isolated, purified and preserved for future use.

Achievement/Findings:

Based on the morphological characteristics 300 symptomatic samples were collected. Among the locations, the highest disease incidence (90%) of panama was found in Chapa at Chupinagar, Shahjahanpur, Bogura (24⁰77'04"N, 89⁰50'45"E) and the lowest disease incidence (5%) of Fusarium wilt was recorded in Sabri/Anupom and Plantain varieties at Gabtoli, Bogura (24⁰51'54.061"N, 89⁰24'57.306"E). In case of Chapa, the disease incidence ranged 20 to 90% and in Sabri 5 to 60%. The infected roots investigated and the pathogen was identified. Isolates of Fusarium oxysporum f.sp. cubense were isolated, purified, store in slants and refrigerated. This information will be needed for further study by using molecular tools.
