Sclerotinia stem rot (SSR) is one of the most destructive disease mustard which affects quality and quantity crop resulting in severe yield losses. The present study was conducted to evaluate bio-efficacy different Trichoderma spp. plant extracts against sclerotiorum under laboratory conditions. All tested showed a significant effect on growth inhibition test fungus over control. Among spp., ma...

Biological control agents (BCA) are beneficial organisms that are applied to protect plants from pests. Many fungi of the genus Trichoderma are successful BCAs but the underlying mechanisms are not yet fully understood. Trichoderma cf. atroviride strain LU132 is a remarkably effective BCA compared to T. cf. atroviride strain LU140 but these strains were found to be highly similar at the DNA seq...

Medicinal plants may become a favourable habitat for associative microorganisms, especially endophytic microbes inhabiting Zingiberaceaen species. Preliminary investigation has revealed an assemblage of fungi colonizing the healthy rhizome Elettaria sp. collected from Sibayak Forest, North Sumatra based on molecular evidences. This study investigated IAA-producing and antifungal activity Elleta...

Green Moldresponsible for the reduction in yield of Ganoderma mushroom, a higher temperature were isolated and identified. Based on symptomatology morphological characteristics green moldthe pathogen was identified as Trichoderma atroviride showing an incidence 68.9 -70 percent, respectively. The studies conducted under vitro conditions indicated efficacy Bavistin (0.1%, 0.05%, 0.025%), Antraco...

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...

Trichoderma species are used commercially as biocontrol agents against a number of phytopathogenic fungi due to their mycoparasitic characterisitics. The mycoparasitic response is induced when Trichoderma specifically recognizes the presence of the host fungus and transduces the host-derived signals to their respective regulatory targets. We made deletion mutants of the tga3 gene of Trichoderma...

genus trichoderma is a monophyletic fungus which some their species is known as biocontrol agent. this study was carried out for phylogenetic analysis of some isolates of the genus trichoderma. in this study 73 sequences (including 33 sequences from t. aspereluum, t. brevicompactum, t. capillare, t. harzianum, t. koningiopsis, t. pleuroticola and t. virens and 40 sequences obtained from geneban...

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...
