Groundnut (Arachis hypogaea L.) suffers from many soil borne pathogens that deteriorate the quality of seeds and are responsible for high yield loss. Practically Trichoderma sp. is used seed treatment, it minimizes supports plant growth promotion activities. In present study, five different isolates spp. were isolated groundnut (A. ) rhizosphere soil. All confirmed by morphological methods usin...

Trichoderma strains were evaluated under field conditions to assay their efficacy in suppressing Alternaria fruit rot disease and promoting chili plant growth. The experiment was conducted at the Botanical Garden, Rajshahi University, Bangladesh from July 2006 to March 2007. Application of Trichoderma harzianum IMI 392432 significantly (p = 0.05) suppressed the disease compared to Alternaria te...

This work presents results on the effect of manganese ions on the development and biological activities of the fungal antagonists Trichoderma harzianum, Trichoderma pseudokoningii and Trichoderma viride. The effects of manganese on linear growth of Trichoderma spp. depend on the metal concentration and the fungal species. T. harzianum proved the most sensitive fungus. on the other hand, none of...

Maize is the main crop for Mexicans; however, it affected by species of fungi causing ear rot. This research aimed to evaluate effect T. asperellum T11, harzianum T1 4 y longibrachiatum 40 on some agronomic variables four maize genotypes. The seeds genotypes H-515, Zapata 7, and H-507 were treated with a suspension Trichoderma spp. 1 × 108 spores mL-1, using control (untreated seed), Benomyl as...

Trichoderma harzianum is a ubiquitous species in the environment and is effective in the biological control of plant-pathogenic fungi. T. harzianum has not been linked unequivocally to its sexual state nor has its phylogeny been studied in detail. It has been suggested that T. harzianum is a species complex based on the phenotypic and genotypic variability encountered. On the basis of morpholog...

ELAD, Y., 1. CHET, and J. KATAN. 1980. Trichoderma harzianum: A biocontrol agent effective against Sclerotium rolfsii and Rhizocionia solani. Phytopathology 70:119-121. An isolate of Trichoderma harzianum capable of lysing mycelia of The wheat bran preparation of T. harzianum increased growth of bean Sclerotium rolfsii and Rhizoctonia solani was isolated from a soil naturally plants in a noninf...

The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produce...

A new species of Trichoderma (teleomorph Hypocrea, Ascomycota, Sordariomycetes, Hypocreales, Hypocreaceae), T. amazonicum, endophytic on the living sapwood and leaves of Hevea spp. trees is described. Trichoderma amazonicum is distinguished from closely related species in the Harzianum clade (e.g. Hypocrea alni, H. brunneoviridis, H. epimyces, H. parepimyces, T. aggressivum, T. harzianum, T. pl...

Phylloplane fungi of Chlorophytum tuberosum were screened for their antagonistic activities against Colletotrichum dematium in vitro. Volatiles produced from the cultures of Trichoderma harzianum ISO-1 showed maximum inhibition of mycelial growth of C.dematium followed by T. piluliferum, T. harzianum ISO-2 and Aspergillus niger,
