Overlooking the importance of insect disease can have disastrous effects on insect conservation. This study reported the microfungi that infect Pteroptyx bearni eggs and larvae during ex-situ rearing project. Two different species of microfungi that infected the firefly's immature life stages were isolated and identified. Penicillium citrinum infected the firefly's eggs while Trichoderma harzia...

Production of extracellular endochitinase could be increased 5-fold in the mycoparasite fungus Trichoderma harzianum by using the cellulase promoter cbh1 of Trichoderma reesei, whereas the total endochitinase activity increased 10-fold. The cbh1 promoter was not expressed on glucose and sucrose in T. harzianum and was induced by sophorose and on cellulase-inducing medium. The endogenous endochi...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

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...

Trichoderma species are commercially applied as biocontrol agents against numerous plant pathogenic fungi due to their production of antifungal metabolites, competition for nutrients and space, and mycoparasitism. However, currently the identification of Trichoderma species from throughout the world based on micro-morphological descriptions is tedious and prone to error. The correct identificat...

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screeni...

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...

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...

Trichoderma harzianum is one of the most beneficial microorganisms applied on diverse crops against biotic and abiotic stresses and acts also as a plant growth-promoting fungus. Here, we report the genome of T. harzianum B97, originating from a French agricultural soil and used as a biofertilizer that can tolerate abiotic stresses.
