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...

Endophytic Trichoderma is a fungus found in plant tissue and has the potential as biological control agent. The aim of this study was to endophytic isolated from tomato roots, stems leaves Phytophthora infestans fruit rot growth yield plants. treatments that were tested tricoderma plants applied with doses 50, 75, 100 g per plant, respectively. experimental design used completely randomized thr...

GOCHEV, V. K. and A. I. KRASTANOV, 2007. Isolation of laccase producing Trichoderma spp. Bulg. J. Agric. Sci., 13: 171-176 Based on its dye decolorization activities four Trichoderma strains were screened as laccase producers. The strains were identified as T. atroviride, T. longibrachiatum, T. reesei, and T. viride. It was determined that it was expedient to screen laccase producing Trichoderm...

In this study, seven Trichoderma species (33 strains) were classified using secondary metabolite profile-based chemotaxonomy. Secondary metabolites were analyzed by liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS) and multivariate statistical methods. T. longibrachiatum and T. virens were independently clustered based on both internal transcribed spacer (ITS...

The antagonistic potential of Trichoderma strains was assayed by studying the effect of their culture filtrate on the radial growth of Sclerotium rolfsii, the causal agent of chickpea collar rot. Trichoderma harzianum-1432 (42.2%) and Trichoderma atroviride (40.3%) were found to be strong antagonists. To enhance their antagonistic potential, mutagenesis of these two selected strains was perform...

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,...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

A plate confrontation experiment is commonly used to study the mechanism by which Trichoderma spp. antagonize and parasitize other fungi. Previous work with chitinase gene expression (ech42) during the precontact period of this process in which cellophane and dialysis membranes separated Trichoderma harzianum and its host Rhizoctonia solani resulted in essentially opposite results. Here, we sho...

Mycoparasitic species of the fungal genus Trichoderma are potent antagonists able to combat plant pathogenic fungi by direct parasitism. An essential step in this mycoparasitic fungus-fungus interaction is the detection of the fungal host followed by activation of molecular weapons in the mycoparasite by host-derived signals. The Trichoderma atroviride MAP kinase Tmk1, a homolog of yeast Fus3/K...

The influence of light on living organisms is critical, not only because of its importance as the main source of energy for the biosphere, but also due to its capacity to induce changes in the behaviour and morphology of nearly all forms of life. The common soil fungus Trichoderma atroviride responds to blue light in a synchronized manner, in time and space, by forming a ring of green conidia a...
