Four techniques (microscope sizing, calculation from settling velocities, image and laser analysis) are available nowadays for determining the particle size distribution of upflow anaerobic sludge blanket (UASB) reactor sludge. These present however disadvantage being either tedious, imprecise or expensive hardly applicable in full scale treatment plants. There was then need a simple low cost technique. In this study, granulometry procedure based on manual humid sieving evaluated. It shown...
In recent decades, a legion of monopartite begomoviruses transmitted by the whitefly Bemisia tabaci has emerged as serious threats to vegetable crops in Africa. Recent studies Burkina Faso (West Africa) reported predominance pepper yellow vein Mali virus (PepYVMLV) and its frequent association with previously unknown DNA-B component. To understand role this component emergence PepYVMLV, we assessed biological traits related virulence, accumulation, location tissue transmission. We...
Abstract Mostly found in Africa and its surrounding islands, African streak viruses (AfSV) represent the largest group of known mastreviruses. Of thirteen AfSV species that are to infect either cultivated or wild Poaceae plant species, six have been identified on Reunion Island. To better characterize diversity this island, we undertook a survey small agroecosystem using new metagenomics-based approach involving rolling circle amplification with random PCR tagging (RCA-RA-PCR),...
Okra leaf curl disease (OLCD) is commonly observed in okra (Abelmoschus esculentus) crops several African countries (N'Guessan et al., 3). Affected plants are severely stunted with apical (upward or downward), distortion and thickening of the veins. In Africa, OLCD associated a complex strains two begomovirus species: Cotton Gezira virus (CLCuGV; Idris & Brown, 2) yellow crinkle (OYCrV; Shih 4). 2012 2013, severe symptoms curling, deformation, vein (Fig. 1), resembling those were on four...
In West and Central Africa, as in many regions of the world, vegetables are severely affected by geminivirus diseases. Burkina Faso, observation various virus‐like symptoms, especially on tomato, suggests involvement several geminiviruses underlines pressing need for additional information their diversity, distribution, prevalence host plant reservoirs. Large‐scale surveys conducted Faso confirmed presence tomato (yellow) leaf curl diseases (ToLCD‐TYLCD) all localities with mean prevalences...
Basal rot is a widespread onion disease caused by fungi belonging to Fusarium genus. The known incur yield loss worldwide. This study aims identify and determine the pathogenicity of species associated with basal onions in Burkina Faso. Thirteen isolates from seven regions Faso were identified based on morphological observations molecular diagnosis their was assessed laboratory Greenhouse. Results showed that, 13 belonged falciforme, acutatum oxysporum species. F. pathogenic seeds, seedlings...
In Mali (Zhou et al., 4) and Burkina Faso (Tiendrébéogo 3), pepper yellow vein disease (PYVD) is associated with the African monopartite begomovirus Pepper virus (PepYVMLV). January 2012 August 2013, severe yellowing, leaf curling deformation symptoms (Fig. 1), resembling those of PYVD were observed on (Capsicum spp.) across Côte d'Ivoire (Table 1). Twenty samples from plants collected tested for presence begomoviruses using a PCR assay set degenerate primers designed to amplify coat protein...
In Burkina Faso, onions (Allium cepa L.) are one of the main vegetable crops. It is a very important source income for producers. However, its production subject to loss, ones being disease caused by fungal pathogens, including Fusarium falciforme, which causes basal rot. This study aimed contribute onion improvement through agroecological methods setting up pathogenicity test and an antifungal based on essential oils local plants against falciforme. For test, conidial suspension each strain...
Geminiviruses are known as responsible for huge damage to vegetable crops in many tropical, subtropical, and temperate regions. In Burkina Faso, tomato was reported the most infected crop with involvement of several geminivirus species despite its socioeconomic importance. This suggests underlines pressing need additional information on virus population evolution (diversity, prevalence, host plant reservoirs). Thus, address this problem, surveys sample collection were carried out three...
Medicinal herbs occupy an important place in the treatment of diseases Burkina Faso. However, they live near crops which are strongly impacted by with typical symptoms begomovirus infection. These medicinal may host these viruses, highlighting need for further study. The purpose this study was to inventory hosts begomovirus. For this, a survey carried out among elderly using semi-structured interviews based on questionnaire. This allowed wide diversity used Heliotropium indicum and Euphorbia...
Solanaceous fruits are economically important and contribute to food security worldwide. Despite this importance, solanaceous crops confronted with constraints, including begomoviruses. In Burkina Faso, the pepper yellow vein Mali virus (PepYVMLV) tomato leaf curl (ToLCMLV) have been reported be most widespread They responsible for deformation yellowing in Solanaceae crops. The use of resistant/tolerant accessions would help finding suitable solutions. This study aims appropriate effective...
The presence of forest species in cashew orchards Burkina Faso, linked to their lack maintenance, serves as a hotspot for the emergence pathogens such bacteria from Xanthomonas citri species. Identifying these acting reservoirs this bacterium various could contribute management. To end, inventory allowed us identify present orchards, mango and mixed cashew/mango orchards. Molecular identification 11 strains was carried out through analysis atpD housekeeping gene sequences. population sizes...
Tomatoes are a widely consumed fruit, important economically and in terms of food security. Despite this importance, tomato crops confronted with constraints, including begomoviruses, such as the Pepper yellow vein Mali virus (PepYVMLV). Responsible for leaf deformation yellowing cultivated Solanaceae, it is most virulent begomovirus infecting tomatoes Burkina Faso. The use resistant/tolerant accessions would be great help finding suitable solutions. This study aims to contribute appropriate...
