Chia (Salvia hispanica L.) is one of the most important medicinal plants recently introduced to Egyptian cultivation and has significant multiusing in human curing. Fusarium oxysporum, F. roseum, semitectum, solani, Macrophomina phaseolina, Pythium ultimum, Rhizoctonia solani Sclerotinia sclerotiorum were isolated from infected plants, showing root stem rot symptoms collected different localiti...

Abstract Background Brown spot disease is one of the most destructive foliar diseases rice. Biological control this considered more environmentally safe, but biological agents have limited availability. The fungus Trichoderma can be used as a biocontrol agent for various plant diseases, including brown spots. Indigenous species from West Timor were evaluated in study to reveal their effectivene...

The experiment was conducted under in vitro and field conditions to observe the effect of bio-agents, botanical and fungicides against Alternaria triticina. Eight treatments were taken up with three replications and data collected was analyzed using CRD. Maximum inhibition per cent mycelia growth was observed in Propiconazole (89.72%), Hexaconazole (88.44%), Vitavax (87.70%), followed by Tricho...

We surveyed the Trichoderma (Hypocreales, Ascomycota) biodiversity in agricultural fields in four major agricultural provinces of East China. Trichoderma strains were identified based on molecular approaches and morphological characteristics. In three sampled seasons (spring, summer and autumn), 2078 strains were isolated and identified to 17 known species: T. harzianum (429 isolates), T. asper...

The biological effectiveness of twenty-eight native isolates Trichoderma along with two known species (Trichoderma viride and harzianum) were tested against Rhizoctonia solani using dual culture technique. Of them, seven the in pot under net-house conditions wirestem disease cauliflower caused by R. solani. Inhibitory effects on statistically very significant for all Trichoderma. Thirteen exhib...

A marine Ascidian-associated fungus, Trichoderma harzianum, (NIO/BCC2000-51) was assessed for its in vitro antagonistic activity against ten fungal phytopathogens and three food-infesting fungi. Fractionation of the cell-free culture filtrate of T. harzianum (NIO/BCC2000-51) showed its ethyl acetate (EA) fraction to be significantly active against fungal phytopathogens; Macrophomina sp, Pyricul...

Trichoderma spp. are endophytic plant symbionts that are widely used as seed treatments to control diseases and to enhance plant growth and yield. Although some recent work has been published on their abilities to alleviate abiotic stresses, specific knowledge of mechanisms, abilities to control multiple plant stress factors, their effects on seed and seedlings is lacking. We examined the effec...

Several proteins and peptides of microbial origin are reported for their elicitor properties, which play a vital role in the development of local and systemic resistances in plants. In this study, the efficacy of total crude proteins (TCP) extracted from six different Trichoderma spp. (T. asperellum, T. harzianum, T. atroviride, T. virens, T. longibrachiatum, and T. brevicompactum) was evaluate...

Mycoparasitism of fungal plant pathogens by Trichoderma species is a complex process that involves the production and coordinated secretion of cell-wall degrading enzymes. Genes implicated in mycoparasitism by Trichoderma atroviride contain motifs in the promoter region, designated MYRE1-MYRE4, that are proposed to act as binding sites for a global inducer of the mycoparasitic response. The aim...
