“…Banana bunchy top virus is one of the most damaging viruses on banana (Musa sp.) (Kumar et al, 2011) and it is expanding in Africa including Benin and Nigeria in West Africa (Kumar et al, 2011;Lokossou et al, 2012;Adegbola et al, 2013). However, unlike the other 4 banana viruses causing symptoms including mosaics that we indexed, Banana bunchy top disease has very characteristic symptoms on banana.…”

103 farmers' plots located in 13 important plantain productions regions were screened. In all, 424 samples having symptoms of yellow or moderate chlorotic streaks were analyzed by reverse transcriptase-PCR and by immunocapture-PCR. Viruses identified were BSOLV, BanMMV and CMV respectively in proportions of 78%, 63% and 5.4% of the samples analyzed. Mixed infections of these three viruses were found in the 13 regions while CMV was present only in 3 regions. None of the samples collected were infected by BBrMV. Infected suckers used by farmers to establish their banana field could be the cause of these viral infections. The results showed that 9% of symptomatic samples were not associated with the presence of one or the other of the viruses studied. Further study is required to identify reported viruses in banana and plantain across the world.

“…Banana is a major income and food security crop for poor smallholder farmers in Africa (Gassner et al., 2019; Marchal, 1990) and provides economic and social benefits for men and women in many rural areas of Africa (Akinyemi et al., 2010; Lokossou et al., 2012). Men and women play different roles in banana production (Ajambo et al., 2018) and have different opportunities and challenges in the banana production process.…”

Enhancing opportunities for women and men in banana production is vital for promoting gender equity in sub-Saharan Africa. This study investigated the gendered differences in access to and decision-making over banana production resources and services in banana bunchy top disease affected areas in Cameroon. A mixed methods approach was used, comprising an intra-household survey ( n = 109 households). Six sex disaggregated focus group discussions and key informant interviews were organized to collect primary data in three communities in Ambam District in Southern Cameroon. These data were used to compare men and women in resource access and production within households and villages. Men had greater say in decision-making over productive resources and information services even when women were more involved in actual seed and site selection. Planting materials were mainly sourced from old fields although men were more likely to buy banana seeds than women farmers. In practical terms, access to and decision-making over production resources and services by women in the banana seed systems is vital for equitable outcomes. Disease pressure on banana production experienced in southern Cameroon may influence gendered access to resources upsetting resource access equity. In theoretical terms, the study reveals dimensions of gender linked differences in resource control even where participation was evident. Thus, it indicates the need for in-depth understanding of power and social relations within households and the communities. This study reveals the nexus of disease challenge and resource access in banana systems. The study will be of interest to development practitioners, researchers and extension agents.

“…Disease spread is constrained at higher altitudes (Niyongere et al ., 2013). BBTD was detected in Benin in 2012 with outbreak zones increasing throughout the southern half of the country since that time (Lokossou et al ., 2012). In each site, new fields were planted with BBTD‐free planting material, and infections seen were a result of natural BBTD infestations in the surrounding area.…”

“…Banana bunchy top disease (BBTD) is one of the most significant threats to banana production in Africa today (Niyongere et al ., 2015). It is now reported in at least 16 countries in the continent, and affects about 6–12 million smallholders (Kumar et al ., 2011; Lokossou et al ., 2012; Jooste et al ., 2016). Both the banana bunchy top virus (BBTV; genus Babuvirus , Nanoviridae ) and its aphid vector Pentalonia nigronervosa (Homoptera; Aphididae) are so far known to only infest bananas, although a second vector P .…”

The removal of infected individuals is a common practice in the management of plant disease outbreaks. It minimizes the contact between healthy individuals and inoculum sources by reducing the infectious window of contaminated individuals. This requires early detection and consistent removal at landscape scale. Roguing of mats with symptoms of banana bunchy top disease (BBTD) in Cavendish banana production systems has been tested in Australia, using trained personnel, but has never been tested in smallholder systems. We studied the effectiveness of long‐term consistent roguing in prolonging the productivity of banana orchards under smallholder farming systems in highland banana and plantain dominated production systems in Africa. We assessed the possibility of low‐risk seed sourcing from the managed plots. Roguing reduced BBTD incidence to 2% in managed farmer fields and to 10% in experimental field plots, while a nonmanaged field eventually collapsed in the same period. With roguing, new infections decreased monthly compared to an exponential increase in a nonmanaged field. The emergence of new infections in both managed and nonmanaged farms followed a seasonal cycle. BBTD managed plots were a source of low‐risk seed for replacing the rogued mats in the same fields, but perhaps not safe for use in nonendemic areas. We conclude that it is possible for smallholder farmers to recover and maintain banana productivity with rigorous roguing, which would entail early identification of symptoms and early removal of diseased mats. Studies are needed on the intensity of roguing under different disease and production conditions.
