Banana Xanthomonas Wilt (BXW) is an important emerging and non-curable infectious plant pathogen in sub-Saharan Africa that can cause up to 100% yield loss, negatively impacting sustainable access to food and income to more than 100 million banana farmers. This study disentangles adopters into partial and full adopters to investigate the factors that are relevant to sustain the adoption process of BXW control practices and quantifies the impact of adopting the practices. Data from a randomly selected sample of 1200 banana farmers in Uganda where the disease is endemic was used. A multinomial logit model was used to determine the factors affecting adoption of control practices and augmented inverse probability weighting was employed to estimate the impacts of adoption on banana productivity and sales. Results show that training a woman farmer and having diverse sources of information about BXW control practices increased adoption of the control practices and reduced the disease incidences. Farmers who adopted all the recommended control practices achieved significantly the highest values of banana production and sales. We conclude that improving information access through farmers’ preferred communication channels, having women-inclusive trainings, and a combination of cultural practices are effective ways for sustaining adoption of the control practices.

Banana wilt diseases are among the most important banana production constraints worldwide. The narrow genetic diversity of cultivated bananas, coupled with the high variability of pathogens, has led to decimation of susceptible cultivars. Strict quarantine measures to exclude pathogens from disease-free areas and the use of resistant cultivars in already affected areas are the most effective control practices. Significant research efforts have been directed towards breeding additional resistant hybrids. Current research strategies for management of banana wilts have explored use of conventional breeding, somaclonal variation and genetic engineering. This review describes the recent spread, economic losses, management strategies and future research directions of the major banana wilts.

The banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is an important pest of highland banana in East and central Africa. It causes yield loss of up to 100% in heavily infested fields. Studies were carried out in Uganda to evaluate the efficacy of the the plant base incision trap in attracting C. sordidus and to determine the potential of using the trap in enhancing dissemination of the entomopathogenic fungi, Beauveria bassiana for the pest control. Field experiments were carried out in an established banana field of C. sordidus susceptible East African Highland Banana cultivar, Nabusa (AAA-EA). There were significantly more weevils recaptured in the incision trap (14.4%) than the conventional pseudostem trap (4.7%). After laboratory incubation, more weevils died due to pathogen infection from plots where the incision trap was used in combination with B. bassiana (25.9%) compared to where the pathogen was applied around the plant base without the incision (15.9%). Weevils showing signs of mycosis were recovered at 6 and 9 m from the pathogen release point, suggesting that the weevils can pick the pathogen from the aggregation point and disperse it. This data demonstrates that the incision trap is more attractive to C. sordidus than the conventional pseudostem trap and might be used to enhance dissemination of B. bassiana among adults. Key words: Entomopathogenic fungi, horizontal transmission, pseudostem trap.

This study aimed at assessing the level of mobile phone use in Ugandan agricultural extension, and to establish the extent to which mobile phone Viamo’s 3-2-1 service, hosted by Airtel Uganda, was being accessed and how the facility can be improved to boost banana productivity. The results of the study indicate that use of mobile phones for increased banana productivity were dependent on age, gender, household size, income and farming experience. Data collected show that the major information source by farmers was extension agents followed by phones and televisions. Focus group discussions revealed that most farmer participants owned phones (94.3%), had Airtel SIM cards and accessed Viamo service (65%). All respondents were aware of the Viamo service and majority got to know about the service through Airtel SMS notifications (83.3%). Farmers indicated that the four most sought after information elements for increasing banana productivity included material on weather forecasts, pest and disease control, fertilizers and their usage, and markets and their location. The study reveals information gaps with respect to pests and disease diagnosis and management, market prices, weather information, mulching and weeding in different terrains, and sources of clean banana planting material. It was concluded that the service is relevant and contributes to improving farmer knowledge on good banana farming practices. A further step will be to scale up use of the 3-2-1 service for agricultural purposes at country and regional levels.
