Si ngh A, Islam MN (2010) In vitro evaluation of Trichoderma spp against Phytophthora nicotianae. Int. J. Expt. Agric. 1(1), 20-25. The Blank sank disease of tobacco caused by Phytophthora nicotianae results in considerable loss of the crop. This lab study aimed to investigate antagonistic activity of Trichoderma spp isolates against P. nicotianae. Three isolates of Trichoderma harzianum and on...

Filamentous fungi from the genus Trichoderma have been widely investigated due to their considerable production of important biotechnological enzymes. Previous studies have demonstrated that the T. harzianum strain IOC-3844 has a high degree of cellulolytic activity. After excluding the native signal peptide, the open reading frame of the T. harzianum endoglucanase III enzyme was cloned in...

We have isolated three novel strains of Trichoderma (two T. harzianum and one T. atroviride) from wild mushroom and tree bark, and evaluated their biocontrol potential against Sclerotium delphinii infecting cultivated cotton seedlings. T. harzianum strain CICR-G, isolated as a natural mycoparasite on a tree-pathogenic Ganoderma sp. exhibited the highest disease suppression ability. This isolate...

Some 800 soil and rotten wood samples were collected from Gilan, Mazandaran and GolestanProvinces in the north of Iran. By using selective and general media, 217 Trichoderma isolates were obtained belonging to sections Longibrachiatum (69 isolates) and Pachybasium (148 isolates), respectively. Pure cultures were obtained by single conidium and single chain methods. Colony features were recorded...

Trichoderma longibrachiatum IMI061758 possesses a powerful cellulose enzyme complex composed by different cellobiohydrolase, endoglucanase and /3-glucosidase activities. Recently we have cloned the T. longibrachiatum egll gene encoding a /S-{l,4)-endoglucanase activity (1). From an industrial point of view, we are interested in the design of strains which have an increased egll gene dosage. To ...

Understanding the function of Trichoderma species in the control of Phytophthora drechsleri in pistachio orchards is very important.  In this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of Trichoderma harzianum, T. crassum, T. koningii, T.aureoviride, T. asperellum, T. brevicompactum, T.longibrachiatum and T. virens were investigated on ...

O estudo foi realizado com o objetivo de avaliar efeito isolados Trichoderma no crescimento inicial Eucalyptus brassiana e urophylla em condições casa vegetação. Foram utilizados cinco na concentração aproximada 1x 109 conídios por grama arroz colonizado, misturados ao substrato, utilizando-se tubetes capacidade 50 cm3. As espécies E. foram avaliadas quanto à altura (H), comprimento raiz (CR), ...
