Soil nutrient depletion and Xanthomonas wilt (Xanthomonas campestris pv. musacearum) are major causes of declining productivity in smallholder banana systems in East and Central Africa. This study examined the interactive effect of fertilizer and inoculum concentration on development of Xanthomon...

Interactive effects of fertilizer and inoculum concentration on subsequent development of xanthomonas wilt in banana
Management of harvested (senescent) banana pseudostems has implications for efficiency of nutrient use for sole cropped as well as intercropped bananas. Two studies were conducted on aspects of nutrient flows from senescent pseudostems. Sixty one and 55% of the initial N and P, respectively, in s...

The banana weevil Cosmopolites sordidus (Germar) is the most important insect pest of bananas and plantains (Musa spp.). The larvae bore in the corm, reducing nutrient uptake and weakening the stability of the plant. Attack in newly planted banana stands can lead to crop failure. In established f...

Crop diseases significantly suppress plant yields and in extreme cases wipe out entire crop species threatening food security and eroding rural livelihoods. It is therefore critical to estimate the extent to which shocks like disease epidemics can affect food availability and the capacity of smal...

Xanthomonas wilt, caused by Xanthomonascampestris pv. musacearum has, since 2001, becomethe most important and widespread disease of Musa inEast and Central Africa. Over the past decade, newresearch findings and especially feedback from smallscalefarmers have helped in fine-tuning Xanthomonaswilt...

East African highland cooking bananas (Musa spp., AAA) are one of the most important staples in the Great Lakes region of Africa. It has been hypothesized that land use intensification within the region has led to decline in soil fertility, increased pest pressure, and decline in production. To d...

The effects of a leaf spot complex (including Mycosphaerella musicola, M. fijiensis and Cladosporium musae) and leaf pruning on plant growth and yield in highland bananas were investigated in a field trial at Kawanda Agricultural Research Institute. Results from the first ratoon crop revealed tha...

The banana weevil Cosmopolites sordidus Germar, has evaded all efforts to manage it in all banana-based cropping systems except the commercial plantation banana system, where the 2 to 3 year crop cycle and the intensity of management limit the pest survival in that system. Conversely, in backyard...
