Controlled studies to determine the efficacy of pseudostem trapping in reducing adult populations of the banana weevil, Cosmopolites sordidus (Germar), were conducted under farmer conditions in Ntungamo district, Uganda. Twenty-seven farms were stratified on the basis of C. sordidus population de...

Evaluation of pseudostem trapping as a control measure against banana weevil, Cosmopolites sordidus (Coleoptera: Curculionidae) in Uganda
A field study was undertaken in Uganda using highland cooking banana (cv. Atwalira) to test the hypothesis that bananas grown under stressed conditions are more susceptible to attack by Cosmopolites sordidus (Germar). Four banana treatments were employed to create different levels of host-plant v...

The decline of cooking banana production in parts of East Africa has been associated with a loss of soil fertility and increased pest pressure. Previous work indicated that the use of mineral fertilizers at recommended rates is not financially viable on plantations where pest pressure is high. Th...

In Uganda, banana (Musa spp) and coffee (Coffea spp) form the economic base for a big population of small-scale farmers and provide environmental protection. However, their production is currently declining. The two crops are grown in association as intercrops or adjacent monocultures but little ...

A survey of plant parasitic nematodes in the major banana growing areas of Uganda was conducted in 1993. A total of 120 root samples were collected from 24 sites. Eight nematode species belonging to four genera were encountered. The most widespread species were Pratylenchus goodeyi (cob) sher and...

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 cassava whiteflies Aleurotrachelus socialis and Trialeurodes variabilis are outbreak pests which cause high yield losses in the Departments of Tolima and Cauca, Colombia. Studies were undertaken to examine the effects of intercopping and cassava varietal mixtures on whitefly population dynami...

Data are presented on the incidence and severity of (black and yellow) sigatoka leaf spots and Cladosporium freckle in different ecological zones of Uganda. Black sigatoka has become widespread since its arrival in Uganda in 1988. Sigatoka leaf spots were most severe in mid-elevation zones of cen...
