Many species of Trichoderma have attracted interest as agents for the biological control of soil borne fungal pathogens of a range of crop plants. Research on the biochemical mechanisms associated with this application has focused on the ability of these fungi to produce enzymes which lyse fungal cell walls, and antifungal antibiotics. An important group of the latter are the non-ribosomal pept...

Cocoa pod anthracnose is an important disease of cocoa and can reduce yields. Many attempts have been made to control rot on pods but not successful yet. This study aimed examine the potency secondary metabolite crude extracts produced by Trichoderma asperellum Pseudomonas fluorescens solely or in combination controlling field at Silo Bonto Village, Asahan Regency, North Sumatera Province. The ...

A total of 75 isolates belonging to five different species of Trichoderma viz., T. asperellum, T. harzianum, T. longibrachiatum, T. pseudokoningii and T. virens were screened for the production of silver nanoparticles. Although all the isolates produced nanoparticles, T. virens VN-11 could produce maximum nanoparticles as evident from the UV-Vis study. The highest Plasmon band was observed at 4...

Seven different strains of Trichoderma are isolated from wilt infected leguminous crops of a Madhya Pradesh state and tested for their antagonistic activity against Fusarium (soil borne pathogen) which is expressed as a zone of inhibition in the culture plates. The seven strains are identified as Trichoderma viride, T. harzianum, T. asperellum, T. koningii, T. atroviride, T. longibrachiatum, an...

In this study, we evaluated the effect of low and high molecular weight polycyclic aromatic hydrocarbons (PAHs), i.e., Phenanthrene, Pyrene and Benzo[a]pyrene, on the radial growth and morphology of the PAH-degrading fungal strains Aspergillus nomius H7 and Trichoderma asperellum H15. The presence of PAHs in solid medium produced significant detrimental effects on the radial growth of A. nomius...

biological efficacy of trichoderma species may differ due to variations in ecosystems. this study was conducted to assess the biocontrol efficacy of some native trichoderma isolates against fusarium oxysporum, an important causal agent of potato wilt disease under laboratory and greenhouse conditions in shahrood agricultural research center, shahrood, iran during 2006-2007. fourteen isolates we...

Antagonism of fungi the genus Trichoderma and various phytopathogenic was investigated. The strains Trichoderma, which have potential value for production biological products plant protection, been identified. highest fungicidal activity among tested is shown by T. asperellum, determines prospects using this strain as a biofungicide. investigations were carried out in research laboratory Peasan...

Trichoderma asperellum SKT-1 is a microbial pesticide that is very effective against various diseases. Our study was undertaken to evaluate T. asperellum SKT-1 for induction of resistance against yellow strain of Cucumber mosaic virus (CMV-Y) in Arabidopsis plants. Disease severity was rated at 2 weeks post inoculation (WPI). CMV titre in Arabidopsis leaves was determined by indirect enzyme-lin...

El uso de Trichoderma spp en la agricultura orgánica es importante debido a su amplio modo acción que incluye: segregación metabolitos secundarios inducen producción fitoalexinas las plantas y capacidad antagonista, además antibiosis causan degradación paredes celulares otros patógenos inhibiendo desarrollo. objetivo fue evaluar el efecto cuatro cepas sobre parámetros morfológicos rendimiento d...
