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...

Plants have evolved effective mechanisms to avoid or reduce the potential damage caused by abiotic stresses. In addition to biocontrol abilities, Trichoderma genus fungi promote growth and alleviate the adverse effects caused by saline stress in plants. Morphological, physiological, and molecular changes were analyzed in salt-stressed tomato plants grown under greenhouse conditions in order to ...

The present study assessed the efficacy of formulated biocontrol agents and nitrogen fertilization on southern blight control. Antagonism test in vitro was performed to assess inhibitory activity Bacillus methylotrophicus Trichoderma asperellum against growth Sclerotium rolfsii. Tomato seedlings were transplanted into substrate added with ammonium nitrate doses inoculated Ônix (B. methylotrophi...

Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby the characterization and identification of strains at the species level is the first step in the use of a microorganism. The aim of this study was the identification – at spec...

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...

Bu çalışmada, Verticillium dahliae’nın gelişimi üzerine bazı fungal (Trichoderma harzianum, Trichoderma virens, asperellum, viride) ve maya (Saccharomyces cerevisiae) biyolojik kontrol etmenleri ile vermikompost salisilik asit organik maddelerin etkisi araştırılmıştır. Çalışma in vitro vivo koşullarda yürüyülmüş vitro’da antagonizmin derecesi yüzde olarak engelleme oranı belirlenmiştir. In inhi...

Trichoderma (Ascomycetes, Hypocreales) strains that have warted conidia are traditionally identified as T. viride, the type species of Trichoderma. However, two morphologically distinct types of conidial warts (I and II) have been found. Because each type corresponds to a unique mitochondrial DNA pattern, it has been questioned whether T. viride comprises more than one species. Combined molecul...

Alternaria porri causa la enfermedad mancha púrpura en cebolla y los hongos benéficos del género Trichoderma pueden ser usados para su biocontrol, pero es limitado el conocimiento de mecanismos respuesta defensa interacción plantas con A. porri. En este estudio se evalúo actividad las enzimas defensa: glucanasas, quitinasas, catalasas peroxidasa aislado To asperellum El T. seleccionó porque des...

Fungi Trichoderma spp. are present in nearly all soils and other habitats. Most of Trichoderma strains are efficient for control of some pathogens. Some strains induce plant native defence mechanisms. Botrytis cinerea [Pers.: Fr.] causes economic losses on a wide range of cultivated plants and stored fruits. In presented work Trichoderma asperellum [strain T1] isolated from commercial product w...
