Abstract:
Experiments were carried out to evaluate various options to reduce wilting of bananas replanted to rehabilitate farms previously destroyed by Xanthomonas campestris pv musacearum (Xcm). Paring, time taken to cure paring injuries and covering corms with infested or uninfested soil were evaluated. Nine banana cultivars were evaluated for tolerance to infection by Xcm through roots. An average of 75% of corms planted immediately after paring and covered with infested topsoil wilted as compared to 25% incidence when pared corms were covered in uninfested soil and over-layered with infested soil. No plants wilted when pared corms were cured for 3 days before planting. Unpared corms planted and covered with infested soil on the same day they were dislodged from mother plants had an average of 40% wilt incidence. Unpared corms had less wilt incidence if kept for 2{\^a}€“3 days before planting. Differences were observed in cultivar susceptibility to infection through corms and roots with cultivars Enzagata and Yangabi Km5 being least susceptible. Cultivars Gonja, Kibuzi and Pisang Awak were more susceptible with 50{\^a}€“75% wilt incidence in pot trials and 36{\^a}€“45% in field trials. The less susceptible cultivars had fewer and shorter primary roots, and took an average of 69{\^a}€“77 days to wilt while the more susceptible cultivars had more and longer primary roots and wilted within 40{\^a}€“50 days after planting. Results of the study show that adjustments in planting practices could contribute to reducing wilting incidence and hence support efforts to rehabilitate banana productivity in farms devastated by Xcm.

Development of a semi-selective medium for isolating Xanthomonas camprestris pv. musacearum from insect vectors, infected plant material and soil, Mwangi, M., Mwebaze, M., Bandyopadhyay, R., Aritua, V.*, Eden-Green, S., Tushemereirwe, W.

Abstract:
A semiselective medium was developed for isolating Xanthomonas campestris pv. musacearum (Xcm) from infected banana plants, soil and insect vectors. The new medium was named cellobiose-cephalexin agar (CCA) and it contained (L{\^a}ˆ’1): 1 g yeast extract, 1 g glucose, 1 g peptone, 1 g NH4Cl, 1 g MgSO4{\"i}Ώ½7H2O, 3 g K2HPO4, 1 g beef extract, 10 g cellobiose, 14 g agar, 40 mg cephalexin, 10 mg 5-fluorouracil and 120 mg cycloheximide. The medium was evaluated for selectivity using 21 bacterial isolates and for plating efficiency using Xcm. The bacterial isolates included a soilborne Xanthomonas species and three pathogenic Xanthomonas strains that infect cassava, cabbage and beans. Although the plating efficiency of Xcm on CCA was lower (59%) than on non-selective yeast extract peptone glucose agar (YPGA), its selectivity was significantly higher, averaging 60 and 82%, when isolating from banana fruits and soil, respectively. CCA was also superior when isolating Xcm from insect vectors, with selectivity of 48-75%, compared with 8-17% on YPGA. Xanthomonas campestris pv. phaseoli did not grow on CCA, while X. campestris pv. campestris and X. axonopodis pv. manihotis grew, but their colonies were smaller than those of Xcm. Twenty-nine out of 33 suspected Xcm strains isolated from plants, soil and insects using CCA were pathogenic when inoculated onto banana plants, indicating that CCA can be a reliable tool in isolating Xcm populations. The medium should prove useful in studies on ecology, epidemiology and management of the banana bacterial wilt pathogen that is currently ravaging bananas in East and Central Africa.
