“…Black leaf streak may take at least 1 year and often more than 2 years for an outbreak to be detected (Stover and Dickson, 1976) so that it could have arrived in East Africa earlier in the 1980s. An earlier suggestion that black leaf streak was present in Zambia (Raemaekers, 1975) could not be confirmed from samples sent to IMI, but the disease does seem now to be present in Malawi (Ploetz et al, 1992).…”

“…Black Sigatoka is more aggressive, destructive and it has displaced yellow Sigatoka as the predominant leaf spot on banana in most of its range (Ploetz et al 1992;Tushemereiwe and Waller, 1993;Ploezt, 2000). The pathogen infects the plantby both conidia and ascospores, which attacks the leavescausing necrosis either partially or entirely leading to disruption of photosynthesis process that feed the bunch (Ploezt, 2000; Etebu and Young-Harry, 2011; Alvindia, 2012).…”

Emergences of Fusarium wilt, Bacterial wilt and Black Sigatoka diseases have caused banana yield loss of up 100% in Tanzania. Though there have been accumulated empirical data on yield decline due to diseases, lack of disease knowledge and selection of appropriate control methods has been a limiting factor in improving banana production. Therefore, this review focused on identifying different management options for major banana diseases, for purpose of providing reference and decision making tools to farmers, extension officers, researchers and decision makers. Using online resources, we identified several methods which are affordable, applicable and reliable for disease management in the country. These includes sanitation, intercropping, crop rotation, prevention, irrigation, drainage improvement, quarantine, use of silicon/calcium and awareness campaigns. Other method was biological control, which need further research on its applicability and impact on the environment. Moreover the use of resistant cultivars though being important, there is little achievement which have been made on breeding for resistance, because banana are polyploidy, parthenocarpic, have long generation time, loss of resistance and poor acceptability of new cultivars. We also found that, no single method is perfect for management of diseases; this is due to the fact that, in agricultural system, disease challenges rarely occur singly. So the approach to disease management should be pragmatic and geared towards integration of several appropriate methods. We hereby conclude that, researches should focus on identifying the best and feasible combination of control methods that can be used by Smallholder farmers.

“…The first report of black leaf streak in East Africa was from the island of Pemba in 1987 (Dabek & Waller, 1990) and the disease spread rapidly to Zanzibar and thence to the Tanzanian mainland, recently being recorded in Kenya (Kung'u et al,, 1992). An earlier suggestion that black leaf streak was present in Zambia (Raemaekers, 1975) was not confirmed from samples sent to the International Myeologieal Institute (IMI), UK, bul the disease does now seem to be present in Malawi (Ploetz et al,, 1992).…”
