The common bean (Phaseolus vulgaris L.) is one of the most widely farmed legumes, with farmers cultivating a variety of cultivar variants in Kurdistan of Iraq. Total of 50 bean samples were tested to establish their mycological contamination and their toxigenic potential under certain conditions, a variety of fungi may develop within bean grains; some of which have the capacity to synthesize mycotoxins. In current study toxigenic fungi were studied in beans (Phaseolus vulgaris L.) Aspergillus spp., Fusarium spp. and Penicillium spp. were the most frequently isolated genera, followed by Phoma sp., Mucor spp., Alternaria spp., Curvularia spp., Rhizopus spp., Eurotium sp. Chaetomium spp, Yeasts and Drechslera spp. Among 20 Aspergillus 11 strains produced mycotoxins: 30% produced aflatoxins (AFs) ranged between 81-260 ppb; 5% produced ochratoxin A (OTA 70-100 ppb) and 26.6% of Fusarium produced Trichothecene T-2/HT-2 (50-94 ppb). The toxigenic species were A. flavus, A. parasiticus, A. ochraceus, A. carbonarius A. niger and F. sporotrichioides.

“…Of these fungi, Alternaria alternata, Ascochyta spp., Colletotrichum spp., Fusarium spp., and Macrophomina phaseolina were the most frequent and common pathogens of these crops. Alternaria, Aspergillus, Curvularia, Drechslera, Eurotium, Fusarium, Penicillium, Rhizoctonia, Mucor, Rhizopus, Sclerotium, and Gliocladium were the most common fungal genera isolated from various legume seeds (Tseng et al 1995;Ruiz et al 1996;El-Nagerabi and Elshafie 2000;Kritzinger et al 2003;Castillo et al 2004;Kumar et al 2004;Domijan et al 2005;Embaby and Abdel-Galil 2006;Attitalla et al 2010). Fusarium, Penicillium, Rhizopus, Cladosporium and Alternaria were the main seedborne pathogens on the surface of five major seeds of leguminous plants from Ningxia, China (Liu et al 2002).…”

“…The Alternaria, Aspergillus, Curvularia, Drechslera, Eurotium, Fusarium, Mucor, Penicillium, Rhizoctonia, Rhizopus, Sclerotium, and Gliocladium were the most common fungal genera isolated from different legume seeds: broad bean (Vicia faba), kidney bean (Phaseolus vulgaris), lupine (Lupinus termis), cowpea (Vigna sinensis), chickpea (Cicer arietinum) and pea (Pisum sativum) under different environmental conditions throughout the World (Tseng et al 1995;Ruiz et al 1996;El-Nagerabi and Elshafie 2000;Kritzinger et al 2003;Castillo et al 2004;Kumar et al 2004;Domijan et al 2005;Embaby and Abdel-Galil 2006;Attitalla et al 2010). Fusarium semitectum, F. graminearum, F. chlamydosporum, F. equiseti, F. proliferatum and F. subglutinans were the most dominant fungal species in the seeds of Phaseolus vulgaris and Vigna sinensis from Argentina and South Africa (Castillo et al 2004;Kritzinger et al 2003).…”

Leguminicolous fungi associated with some seeds of Sudanese legumes

The mycoflora associated with seeds evidently deteriorate seed viability, germination, emergence and plant growth performance leading to apparent losses in production and productivity. In the present investigation, seedborne fungi of six legumes were screened. Twenty six species of fungi from 14 genera were isolated from this seeds. Of these isolates, 6 species are new reports to the mycoflora of Sudan, whereas some species are new records to the mycoflora of these legumes. These include 6 species for Cajanus cajan, Cicer arietinum (10 species), Dolichos lablab (7 species), Medicago sativa (8 species), Phaseolus vulgaris (10 species), and Vigna unguiculata (11 species). The seeds are obviously contaminated with saprophytic and pathogenic fungi (17-64%) which evidently inhibited seed germination (41-86%), and seedling emergence (29-81%). The Alternaria, Aspergillus and Fusarium (4 species each) were the most prevalent fungi followed by Curvularia, Drechslera (3 species), Fusariella, Ulocladium (2 species) and one species for the remaining genera (Aureobasidium, Acremonium, Memnoniella, and Rhizopus). Hence, there is a high need for establishment of standard seed testing methods with strong legislations in order to meet the international quarantine regulations. The use of certified seeds by the farmers is recommended.
