Fungal pathogens pose a major problem in causing reduction in yield of vanilla crop to considerable level. Fusarium oxysporum, was isolated from naturally infected vanilla plants and an attempt was made to minimize the damage caused by the pathogen using biocontrol agents Trichoderma harzianum, and Pseudomonas fluorescens isolated from soil. The combined inoculation of Trichoderma harzianum wit...

Interactions between leaf-cutting ants, their fungal symbiont (Leucoagaricus) and the endophytic fungi within the vegetation they carry into their colonies are still poorly understood. If endophytes antagonistic to Leucoagaricus were found in plant material being carried by these ants, then this might indicate a potential mechanism for plants to defend themselves from leaf-cutter attack. In add...

Wilt-susceptible cultivar 'Rowden' cotton was inoculated wilh Meloidogyne incognita (N), Trichoderma harzianum (T), and Fusarium oxysporum f. sp. vasinfectum (F) alone and in all combinations in various time sequences. Plants inoculated with F alone or in combination with T did not develop wilt, Simultaneous inoculation of 7-day-old seedlings with all three organisms (NTF) produced earliest wil...

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...

Nineteen isolates of Trichoderma viride and Trichoderma harzianum obtained from rhizosphere soil of plantation crops, forest soil and agricultural fields of North Bengal region were studied using RAPD and ITS-PCR. The genetic relatedness among eleven isolates of T. viride and eight isolates of T. harzianum were analyzed with six random primers. RAPD profiles showed genetic diversity among the i...

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...

Fungi in the genus Trichoderma have been used for the production of lytic enzymes and to control a wide range of plant pathogenic fungi. In the last years, much progress has been made in elucidating the molecular biology of Trichoderma spp. The objective of this chapter is to provide a summary of data concerning size and organization of the genome and gene structure in Trichoderma spp., mainly ...

The study is attempted to investigate the production of potent lipase from groundnut oil mill fungi. The fungi was isolated and identified as Trichoderma sp. Lipolytic activity of Trichoderma sp. was preliminarily confirmed by Rhodamine B method, lipase production was carried out using mineral medium. The extracellular protein concentration and lipase enzyme activity (7.83U/ml) was maximum at 4...

In the screening for new melanin synthesis inhibitors, we found a novel isonitrile inhibitor, MR304Afrom the culture broth of Trichoderma harzianum. There were someisonitrile antibiotics that were reported to have been isolated from Trichoderma sp. 1 ~ 4) and trichoviridin, one of these isonitriles, showed a melanin biosynthesis inhibitory activity5). In this paper we described the fermentation...
