the effect of different isolates of trichoderma namely t. virens t65, t virens t90, t. virens t96, t. virens t122, t. brevicompactum t146, t. koningiopsis t149, t. viridecense t150, t. koningii as well as two trichodermin b and subtilin commercial bioproducts on growth promotion in wheat were studied through seed coating method in a compeletly randomized design in a glasshouse experiment. the i...

The soilborne pathogens Rhizoctonia solani, Pythium ultimum, and Meloidogyne incognita can cause severe economic losses to fieldand greenhouse-grown cucumber. A collection of bacterial isolates and isolates GL3 and GL21 of Trichoderma virens were screened for suppression of diseases caused by these pathogens. T. virens isolates GL3 and GL21 provided the most effective suppression of damping-off...

Trichoderma virens (synonym, Gliocladium virens), a deuteromycete fungus, suppresses soilborne plant diseases caused by a number of fungi and is used as a biocontrol agent. Several traits that may contribute to the antagonistic interactions of T. virens with disease-causing fungi involve the production of peptide metabolites (e.g., the antibiotic gliotoxin and siderophores used for iron acquisi...

application of trichoderma species is a harmless method in controlling soil borne plant diseases thus reducing hazardous pesticide use and environmental pollution. some trichoderma isolates performing proper inhibitory effect against fusarium oxysporum f. sp. tuberosi under laboratory and green house conditions were screened against wilt disease of potato caused by this pathogen under field con...

Biotic elicitors can be used to stimulate the production of secondary metabolites in plants. However, limited information is available on the effects of biotic elicitors from endophytic fungi on their host plant. Trichoderma atroviride D16 is an endophytic fungus isolated from the root of Salvia miltiorrhiza and previously reported to produce tanshinone I (T-I) and tanshinone IIA (T-IIA). Here,...

trichoderma harzianum (t39), t.virens (dar74290), t.viride (mo), t. harzianum (m) and trichderminb a commercial formulation of t. harzianum(bi) were evaluated as potential biological agents for the control of charcoal stem rot in melon caused by macrophomina phaseolina. cell-free metabolites of t. harzianum(m), t. harzianum (t39) and t. virens (dar 74290) inhibited growth of m. phaseolina compl...

The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produce...
