Helminthosporium (Bipolaris) causes a leaf spot disease in Chrysalidocarpus lutescens (cane palm) in Sri Lanka. The losses could reach 90% of production during rainy weather conditions. Field experiments were carried out to test the efficacy of treatment of seeds of C. lutescens against Helminthosporium infection. In the fungal growth tests the isolates T.harzianum 1, T.harzianum 2, T.viride 1,...

Damping-off of chilli caused by Pythium aphanidermatum is a major nursery disease in vegetables. In vitro experiments evaluated the effect of eight isolates of Trichoderma species (from chilli rhizosphere) were tested against P. aphanidermatum. All the Trichoderma species had varied antagonistic effects against the pathogen. Among them, TVC3 recorded maximum growth inhibition of P. aphanidermat...

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...

Trichoderma theobromicola and T. paucisporum spp. nov. are described. Trichoderma theobromicola was isolated as an endophyte from the trunk of a healthy cacao tree (Theobroma cacao, Malvaceae) in Amazonian Peru; it sporulates profusely on common mycological media. Trichoderma paucisporum is represented by two cultures that were obtained in Ecuador from cacao pods partially infected with frosty ...

The main purpose of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as municipal solid waste residue. In the present investigation, we aim to isolate the two novel cellulase producing fungi (Aspergillus niger and Trichoderma sp.) from municipal solid waste. Municipal solid waste residue (4-5% (w/v)) and pep...

The hydrolytic potential of cellulases produced by Trichoderma viride, Trichoderma pseudokoningii, Trichoderma koningii, and Trichoderma reesei with addition of exogenous β-glucosidase was evaluated on cellulose of steam-pretreated Lespedeza. The T. viride enzyme achieved the highest glucose conversion (90.09%), while T. pseudokoningii cellulase achieved the highest ratio of cellobiose to gluco...

Seven fungal isolates were identified as pan-global Hypocrea/Trichoderma species, from section Trichoderma, on the basis of their morphology. These species were H. lixii/T. harzianum and H. orientalis/T. longibrachiatum. PCR-based markers with primer M13 (core sequence of phage M13) and internal-transcribed spacer sequences of ribosomal DNA were used to confirm the identity of the two Trichoder...

In this study, the biocontrol abilities of water-soluble and volatile metabolites of three different isolates of Trichoderma (T. asperellum, T. harzianum and Trichoderma spp.) against soil borne plant pathogen Rhizoctonia solani were investigated both in vitro and in vivo. The results showed for the first time that mycelial growth inhibition of the pathogen was 74.4-67.8% with water-soluble met...

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...
