Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc), poses a major threat to banana production globally. A variant of Foc that originated in Southeast Asia, called tropical race 4 (TR4), was detected on a Cavendish banana export plantation (Metocheria) in northern Mozambique in 2013. Foc TR4 was rapidly disseminat...

The coconut palm (Cocos nucifera), an importance cash and subsistence crop, is widely grown in the coastal regions of the tropics, and contributes to a large extend to the livelihood and food security of millions of rural inhabitants in Mozambique. However, coconut production has been challenged by the occurrence of an invasive and emerging pathoge...

The production and utilization of groundnut (Arachis hypogea L) has increased tremendously across all provinces of Mozambique in recent times. However, the presence of mycotoxins, especially aflatoxins has remained a critical food concern in both the human and livestock diet. In this study, the effect of harvesting time and drying methods on aflato...

Groundnut (Arachis hypogaea L.) is one of the most important legume crop in Mozambique which is grown for food as well as cash. It's an indeterminate growth habit and below the ground nature of fruiting makes it difficult to determine the time of optimal maturity of pods. This results in reduced crop yields if either harvested too early or too late...

Groundnut (Arachis hypogaea L.) is the third most important crop in Mozambique. Despite its importance as food, the presence of mycotoxins, especially aflatoxins has the potential to limit its use in both the human and livestock diet. In this study, the effect of time of harvesting on aflatoxin (AF) contamination were examined at two locations in N...

Management of coconut (Cocos nucifera) lethal yellowing disease (CLYD), which has killed about eight million coconut trees in Mozambique, has proved challenging. The objective of this study was to investigate the impact of farming practices and related history, on the CLYD incidence in Mozambique. The methodology included a socioeconomic questionna...

In this study, potential alternate hosts of the phytoplasma causing coconut lethal yellowing disease (CLYD) in Mozambique were investigated based on 16S rRNA and secA genes. The results reveal that the naturalized palm species, Elaeis guineensis and Borassus aethiopum are alternate hosts of CLYD phytoplasma in Mozambique. Based on the iPhyClassifie...

In this study, phytoplasmas associated with coconut lethal yellowing disease in Mozambique were characterized. For phylogenetic analysis the 16S rRNA genes were sequenced. Apart from ‘Candidatus Phytoplasma palmicola’ 16SrXXII-A, phylogenetic analysis revealed the presence of a double infection of ‘Ca. P. palmicola’ and a ‘Ca. P. pini’-related phyt...

In this study, the putative phytoplasma species causing coconut lethal yellowing disease in Mozambique and Tanzania were characterised. The 16S rRNA and secA genes were sequenced. Phylogenetic analysis revealed that Mozambican coconut phytoplasmas belonged to three different types: ‘Candidatus Phytoplasma palmicola’ 16SrXXII-A, a second strain that...

Anthracnose (Colletotrichum gloeosporioides Penz. & Penz.) has been placed the second most important cashew disease in Mozambique. The objective of this study was to identify and evaluate in-vitro, the potential antagonism of commonly observed bacterial contaminants against C gloeosporioides. The causal agent of cashew anthracnose (C. gloeosporioid...

In August and September of 2007, black rot symptoms were observed on seedbed and field plants of Brassica spp. grown in the southern districts of Boane, Mahotas, and Chòkwé in Mozambique. One hundred eighty-two cabbage-growing households were evaluated for the incidence of Xanthomonas campestris pv. campestris. Five Brassica cultivars, Glory F1, Gl...

Black rot has been a main disease constraint of crucifers grown by smallholder farmers in Mozambique. On-farm survey was conducted through triangulation of several social methods. The number of cabbage crops grown per year ranged from one to four. Four Brassica seeds sources were used by the farmers, namely: shops, friends, middle man and own produ...

Sunflower rust, caused by Puccinia helianthi, is common and widespread in Mozambique. Investigations conducted during 1996–1997 to gather information on the incidence and severity of rust infections in southern Mozambique indicated that race 4 (or 700) was the predominant race in the rust population. Further surveys in 2002 revealed an increase in...

Kura clover (Trifolium ambiguum M. Bieb.) has been reported to be resistant to several viruses, including Alfalfa mosaic virus (AMV), Bean yellow mosaic virus (BYMV), Clover yellow vein virus (CYVV), Peanut stunt virus, Red clover vein mosaic virus (RCVMV), and White clover mosaic virus (WCMV) (2). Furthermore, 54 of 61 kura clover plants were resi...
