Biocontrol agents generally do not perform well enough under field conditions to compete with chemical fungicides. We determined whether transgenic strain SJ3-4 of Trichoderma atroviride, which expresses the Aspergillus niger glucose oxidase-encoding gene, goxA, under a homologous chitinase (nag1) promoter had increased capabilities as a fungal biocontrol agent. The transgenic strain differed o...

Sampling of agricultural soils from the Mexican northeastern region was performed to detect Trichoderma spp., genetically characterize it, and assess its potential use as a biologic control agent against Macrophomina phaseolina. M. phaseolina is a phytopathogen that attacks over 500 species of cultivated plants and causes heavy losses in the regional sorghum crop. Sampling was performed immedia...

a pot experiment was designed to evaluate the effect of trichoderma spp. on yield and yield components of wheat (cv. n81) under different levels of cadmium nitrate. experiment was arranged in factorial based on completely randomized design with three replicates. trichoderma harzianum at two levels (with and without inoculation) and four levels of cadmium nitrate (0, 50, 100, 150 mg l-1) were th...

Sheath blight, causes by Rhizoctonia spp., threaten maize yield every year throughout the world. Trichoderma could degrade Rhizoctonia solani on maize mainly via competition and hyperparasitism, whereas validamycin A could efficiently inhibit the growth of R. solani via disturbing the energy system. By contrast, validamycin A is efficient but it takes effect in a short period, while Trichoderma...

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 study of the antagonistic activity eleven isolates Trichoderma spp., against four Botrytis cinerea, collected from diseased tomato plants cultivated in greenhouses located on Algiers coast and north-east Sahara. vitro antagonism was compared to fungicidal "PROLEX", widely used by farmers this phytopathogen Algeria. results revealed a complete inhibition sporulation, germination, production ...

Ni(II) complexes with N-2-fluorobenzoylpiperidine-1-carbothioimidate (L2-), N-4-fluorobenzoylpiperidine-1-carbothioimidate (L3-), N-2-fluorobenzoylmorpholine- 1-carbothioimidate (L5-) and N-4-fluorobenzoylmorpholine-1-carbothioimidate (L6-)  have been synthesized and characterized by elemental analysis, FTIR and 1H-NMR. The crystal structures of three ligands (HL2, HL3 and HL6) and the correspo...

Biocontrol fungi (BCF) are agents that control plant diseases. These include the well-known Trichoderma spp. and the recently described Sebacinales spp. They have the ability to control numerous foliar, root, and fruit pathogens and even invertebrates such as nematodes. However, this is only a subset of their abilities. We now know that they also have the ability to ameliorate a wide range of a...

Introduction: Nutritional requirements of fungi are essential for their successful growth in laboratories. Some fungi feed on the compounds present in the insects' bodies. The aim of this study was to evaluate the effect of insects' body powder (IBP) as a supplement for the fungi growth in culture media. Methods: We used 10 mg of IBP, obtained from Anopheles superpictus and Culex theileri mosqu...
