In this study, dual culture, poison agar, and direct methods were used to assess the ability of Trichoderma virens IMI-392430, T. pseudokoningii IMI-392431, T. harzianum IMI-392432, T. harzianum IMI-392433, and T. harzianum IMI-392434 to control Ceratocystis paradoxa, which causes the pineapple disease of sugarcane. The highest percentage inhibition of radial growth (PIRG) values were observed ...

The capability of the bio-control agent Trichoderma harzianum to trigger plant growth and improvement in biomass response was investigated by inoculating roots of medicinal plant (Ocimum sanctum) seedlings with Trichoderma harzianum in pots, under aseptic, green house environmental conditions. Trichoderma harzianum was isolated from ten different agro climatic zones of Karnataka. Biological and...

in this study, trichoderma harzianum bi was evaluated for its capability to reduce the incidence and severity of the root-knot nematode, meloidogyne javanica, and fusarium wilt, f. oxysporum f. sp. lycopersici, as causal agents of a complex disease of tomato in the laboratory and greenhouse conditions. initial in vitro studies revealed that the parasitism of m. javanica eggs by t. harzianum bi ...

abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...

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...

The production of new generation of wood preservatives (without addition of a co-biocide) in combination with an exchange of wood poles on identical sites with high fungal inoculum, has resulted in an increase of premature failures of wood utility poles in the last decades. Wood destroying basidiomycetes inhabiting sites where poles have been installed, have developed resistance against wood pr...

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...

Fungicides viz., Benomyl, TopsinM, Carbendazim and Cuprocaffro were used at different concentrations i.e., 0, 1, 10, 100, 1000 and 10,000 ppm a.i. to evaluate Trichoderma species viz. T. harzianum, T. pseudokoningii, T. longibrachiatum, T. viride for tolerance to fungicides. Topsin-M and Carbendazim were the most effective fungicides that inhibit the growth of Trichoderma species even at low co...

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...
