Crop sanitation, i.e. destruction of crop residues, has been hypothesized to lower banana weevil damage by removing adult refuges and breeding sites. Although it has been widely recommended to farmers, limited data are available to demonstrate the efficacy of this method. The effects ...

Highland cooking bananas (Musa spp. AAA) are a major staple in Eastern Africa. However, plant parasitic nematodes comprise a primary production constraint. Planting of infested material is the principle means of dispersal for these nematodes, as well as banana weevil and fusarium wilt. Nematode i...

Thirty-seven pairs of accessions of East African highland bananas, listed under the same name in the Ugandan germplasm collections at Kawanda and Kabanyolo, were surveyed for 50 morphological characters. The data were subjected to cluster analysis and principal components analysis. Duplicates kno...

Surveys were undertaken at 24 diagnostic sites in Uganda to determine the distribution and incidence of Fusarium wilt on exotic banana cultivars caused by Fusarium oxysporum f. sp. cubense. Symptoms normally associated with the disease were found to be widespread throughout the major banana growi...

Between 1970 and 1990, highland green cooking banana production rapidly declined in the traditional growing areas in the central region, while during the same period banana production expanded in the country's southwest. Thus, Kampala's growing urban market for banana became dependent upon new gr...

The banana bacterial wilt caused by the Xanthomonas campestris pv. musacearum (Xcm) is one of the major constraints to banana production in Uganda. Field observations suggest that the primary means of disease spread is by insect transmission through the male flowers. This study carried out an inv...

Yield loss in highland banana caused by the banana weevil, Cosmopolites sordidus, was studied in field trials in Uganda. Weevils were released at the base of banana mats 9 months after planting. Weevil populations, corm damage, plant growth and yield were assessed over four crop cycles. The effec...

Damage by banana weevil, Cosmopolites sordidus (Germar), contributed to the decline and disappearance of highland cooking-bananas (Musa spp., type AAA-EA) from the central region of Uganda. Commercial growers in the southwest use chemical insecticides for the control of the weevil although resist...

Under laboratory conditions, nonpathogenic, endophytic Fusarium oxysporum inflicts high mortality among banana weevils and nematodes. Following inoculation into banana (Musa spp.) tissue cultured plants, successful colonisation is necessary for efficient biological control of these pests. The pat...
