“…The genus Fusarium encompasses a range of widely distributed microorganisms that causes fusariosis in cowpea plants and can cause approximately 90% reductions in seed production in susceptible cultivars (Rodrigues et al, 2006;Silva et al, 2011;Teixeira et al, 2012).…”

“…The use of resistant cultivars is recommended for the control of fusariosis in cowpea, but the difficulties in obtaining such cultivars encourage the search for viable alternatives to control the disease (Rodrigues et al, 2006;Teixeira et al, 2012). The use of antagonistic fungi for biological control, such as Trichoderma sp., may be a viable alternative for reducing the incidence of fungi of the genus Fusarium on cowpea.…”

“…The best quality cowpea seeds are the consequence of a positive interaction of genetic, environmental, physiological and, especially, health factors (Teixeira et al, 2012;Dutra et al, 2012). Low quality seeds have a high degree of infestation by phytopathogens, mainly fungi.…”

One of the main causes of low productivity of cowpea crops in Brazil is the use of low quality seeds. Low quality seeds have a high degree of infestation by phytopathogens, mainly fungi. Seed treatment with biological control agents, such as fungi of the genus Trichoderma, is a useful alternative to reduce or inhibit the transmission of diseases via seeds. In view of the above, this study aims to evaluate the physiological and sanitary quality of cowpea seeds treated with conidia of Trichoderma sp. (1.2, 2.4, 4.8 and 9.6 x 108 CFU g-1). We evaluated the germination and the sanity of seeds, length of seedling radicles, and production of indole acetic acid (IAA) by fungi. The experimental design was completely randomized in all experiments. In general, there was a predominance of Fusarium spp. and Rhizoctonia solani. The treatment of seeds with the conidia of Trichoderma sp. was positive for the parameters related to germination and radicle length of cowpea beans up to the concentration 4.8 x 108 CFU g-1. We conclude that the application of Trichoderma sp. was efficient in reducing the incidence of Fusarium spp., and promoted the germination and elongation of the radicle in cowpea.

“…In this way, Trichoderma spp. has acting in resistance induction in several pathosystems(TEIXEIRA et al, 2012;PEDRO et al, 2012).The induction of resistance may be related to changes in protein synthesis. There is a set of proteins related to the interaction of T. harzianumwith pathogenic fungi.…”

“…The obtained mycelia used for various applications, such as obtaining dietary supplements, pharmaceutical applications, conversion of waste into biomass and production of enzymes (11 The T. harzianum isolated from a farm for Agaricus bisporus cultivation has caused losses in mushroom production, while it and other species caused contamination of spawn and agro-substrates (6). At the same time T. harzianum has been reported as an effective biocontrol agent against several plant fungal diseases (29,30,34). Furthermore, T. harzianum may not be able to cause economic loss in the commercial cultivation of P. tuberregium since mycelium of P. tuberregium was able to overgrow completely in the presence of pathogenic fungi (7).…”

This study evaluated the antifungal activity of four fruiting bodies of oyster mushroom harvested from three agro-substrates in vitro. At three concentrations (2, 4 and 8 mg/disc), extracts discs of Pleurotus ostreatus (grey), P. ostreatus var. florida, P. cornucopiae var. citrinopileatus and P. salmoneostramineus were tested against three fungal pathogens: Trichoderma harzianum (after 2 days), Verticillium sp. and Pythium sp. (after 5 days) via the Disc Diffusion Method. The highest overall activity was by the extract disc Y2 (P. cornucopiae grown on M2 substrate; 70% wheat straw, Owaid; M.N.; Al-Saeedi, S.S.S.; Al-Assaffii, I.A.A.Antifungal activity of cultivated oyster mushrooms on various agro-wastes. Summa Phytopathologica, v.43, n.1, p.09-13, 2017.20% hardwood sawdust and 10% date palm fibers) and the lowest by Y1 (P. cornucopiae grown on wheat straw). The best inhibition zone was 16 mm toward T. harzianum by extract disc W2 (2 mg/disc) (P. ostreatus var. florida grown on M2 substrate), compared with 23 mm with Nystatin disc (100 U), followed 7 and 5 mm by P3 (P. salmoneostramineus grown on M3 substrate; 50% wheat straw, 30% hardwood sawdust and 20% date palm fibers) extract disc (8 mg/disc) against Pythium sp., and (4 mg/disc) against Verticillium sp., respectively.Keywords: Pleurotus spp., agro-wastes, contaminated fungi, antifungal activity, bioactivity.The oyster mushroom, Pleurotus spp., is edible and belongs to the fungi kingdom, phylum Basidiomycota (32). About seventy species of Pleurotus spp. have been recorded and new species are being discovered. Many oyster mushrooms are primary decomposers of hardwood trees found worldwide (14). Thus, it can be cultivated on a wide variety of substrates containing lignin, cellulose and hemicellulose (26). It must obtain nutrients from such organic sources as dead organisms since they had absorbed nutrients after digesting large molecules into smaller units because of their secreted enzymes (10); thus, it has been grown in Iraq on various agro-wastes in the wild (18), or manually (5, 17) on cardboard (19,20), date palm wastes (21), and tree sawdust (24).Since ancient times, macrofungi have been used as a valuable food source and as traditional medicines around the world. The fungi constitute an important source for some compounds including enzymes and antibiotics (9). Consequently, the antimicrobial activity of various polysaccharides from medicinal mushrooms is being reevaluated in relation to their clinical efficacy, given that such compounds would be expected to function to ward off bacterial and fungal infections resistant to current antibiotics (31). Medicinal mushrooms are able to synthesize a great amount of secondary metabolites that present antitumoral, antiviral, anti-inflammatory (8), antibacterial, antifungal (23) and anti-yeast activities (25).Currently, a large range of mushrooms species are grown in liquid media. The obtained mycelia used for various applications, such as obtaining dietary supplements, pharmaceutical applications, convers...
