“…Meanwhile, several fungal endophytes were identified with antagonistic activity against F. oxysporum f. sp. cubense TR4 from isolated weeds growing in Cavendish banana farms [55]. Recent data shows that various new cultivars possess high levels of resistance to Foc TR4 although these studies need replication in different environment and in commercial farms [56].…”

Food safety is a major concern worldwide. Food-crop contamination by fungi and mycotoxins is a common occurrence causing persistent exposure that raises critical health problems and economic losses. Food and feeds are frequently tainted by multiple contaminants, such as trace elements, heavy metals, dioxins, pesticides, and mycotoxins. Most African countries lack the ability to enforce international food safety regulations and face frequent rejection of exportable raw food materials leading to financial burden and increased intramural consumption of contaminated products. The literature on mycotoxins is extremely vast, investigating or reporting cellular mechanisms and toxicity, associated pathology and animal performance, effects of these compounds on general malnutrition and on human health. However, different sampling and analytical methods for research has hindered progress, data collection and interpretation. Innovative and promising commercial solutions of technological biocontrol have been approved in few African countries but may not be the sole and long-lasting solution for the management of mycotoxins. We describe an economic burden in Mozambique of naturally occurring toxigenic fungi moulds in banana plantations, and a public health impact from non-rotating crops of cassava, groundnutsб and maize. Finally, we mention our moderate role in surveillance and monitoring of mycotoxins in family smallholder farmers, informal markets, and cooperatives.

“…In the 1990s, TR4 was identified as the causal agent of Fusarium wilt disease infecting Cavendish bananas in Taiwan [2]. The disease caused by TR4 has been reported in 23 countries (predominantly in Southeast Asia, South Asia, Africa, and Latin America) [3]. Moreover, TR4 affected the banana industry and reduced banana yield in the Philippines (FAO 2022).…”

The pathogen causing Fusarium wilt in banana is reported to be Fusarium oxysporum f. sp. cubense (FOC). In 2019, wilt symptoms in banana plants (cultivar: Cavendish) in the Philippines were detected, i.e., the yellowing of the leaves and discoloration of the pseudostem and vascular tissue. The fungus isolated from the vascular tissue was found to be pathogenic to Cavendish bananas and was identified as a new species, F. mindanaoense, belonging to the F. fujikuroi species complex (FFSC); species classification was assessed using molecular phylogenetic analyses based on the tef1, tub2, cmdA, rpb1, and rpb2 genes and morphological analyses. A reciprocal blast search using genomic data revealed that this fungus exclusively included the Secreted in Xylem 6 (SIX6) gene among the SIX homologs related to pathogenicity; it exhibited a highly conserved amino acid sequence compared with that of species in the FFSC, but not with that of FOC. This was the first report of Fusarium wilt in Cavendish bananas caused by a species of the genus Fusarium other than those in the F. oxysporum species complex.

“…According to our previous study [ 21 , 22 ], instead of conventional fertilizer by alkaline fertilizer could significantly increase soil pH and then reduce the occurrence of banana wilt. Although some studies have also shown that biocontrol has an obvious effect on banana Fusarium wilt [ 10 , 23 , 24 , 25 ], the efficacy will be poor if soil acidity is not improved [ 21 , 22 ]. Biocontrol is one of the hot topics of banana Fusarium wilt control before release of the disease resistant variety.…”

The purpose of this study was to determine the effect and mechanism of alkaline fertilizer, bio-control fungi, and their synergistic application on control of Fusarium Tr4 incidence. Synchronized use of the alkaline fertilizer and biocontrol fungi eliminates rhizome browning and reduces the incidence rate of banana Fusarium wilt. The incidence of yellow leaves (ratio of yellow leaf to total leaf) and disease index in +Foc Tr4 CF treatment were the same (65%), while incidence of yellow leaves and disease index in +Foc Tr4 AFBCF were 31% and 33%, respectively. Under the stress of Foc Tr4 infection, the synergistic utilization of the alkaline fertilizer and biocontrol fungi would raise the activities of peroxidase, catalase and superoxide dismutase in banana roots. The root activity of banana was also increased. As a result, the banana height and stem diameter increments, shoot and root dry weight, accumulation of N, P and K in banana plants had been increased. The efficacy of the synergistic application of alkaline fertilizer and biocontrol fungi was not only reducing Foc Tr4 pathogen colonization and distribution in banana plants, but also preventing tylosis formation in vascular vessel effectively. Therefore, the normal transport of water and nutrients between underground and aboveground is ensured.
