Fifteen fungal and three bacterial biological control agents (F-BCA B-BCA, respectively) were isolated from the canola production areas of Western Australia to investigate their potential for controlling sclerotinia stem rot (SSR) caused by Sclerotinia sclerotiorum under in vitro field conditions. The capacity these isolates inhibit mycelial growth sclerotia formation S. was assessed dual cultu...

Lentinula edodes, one of the most important edible mushrooms in China, is affected heavily by the infection of green mold that overgrows mushroom mycelia. We collected the diseased samples from main L. edodes cultivation regions in China to characterize the pathogen and to study the effect of Trichoderma spp. on L. edodes species. We identified six Trichoderma species, that is, T. harzianum, T....

Biological control agents (BCA) are beneficial organisms that are applied to protect plants from pests. Many fungi of the genus Trichoderma are successful BCAs but the underlying mechanisms are not yet fully understood. Trichoderma cf. atroviride strain LU132 is a remarkably effective BCA compared to T. cf. atroviride strain LU140 but these strains were found to be highly similar at the DNA seq...

Medicinal plants may become a favourable habitat for associative microorganisms, especially endophytic microbes inhabiting Zingiberaceaen species. Preliminary investigation has revealed an assemblage of fungi colonizing the healthy rhizome Elettaria sp. collected from Sibayak Forest, North Sumatra based on molecular evidences. This study investigated IAA-producing and antifungal activity Elleta...

Green Moldresponsible for the reduction in yield of Ganoderma mushroom, a higher temperature were isolated and identified. Based on symptomatology morphological characteristics green moldthe pathogen was identified as Trichoderma atroviride showing an incidence 68.9 -70 percent, respectively. The studies conducted under vitro conditions indicated efficacy Bavistin (0.1%, 0.05%, 0.025%), Antraco...

Some 350 Trichoderma isolates were obtained from soil samples collected from different parts of Iran. Cultures were purified on 2% water agar by hyphal tip method prior to identification. Obtained isolates were identified using morphological features including colony characters (pigmentation and growth rate on PDA) and microscopic characters such as shape of conidiophores, shape and size of con...

Trichoderma species are used commercially as biocontrol agents against a number of phytopathogenic fungi due to their mycoparasitic characterisitics. The mycoparasitic response is induced when Trichoderma specifically recognizes the presence of the host fungus and transduces the host-derived signals to their respective regulatory targets. We made deletion mutants of the tga3 gene of Trichoderma...

Seven different strains of Trichoderma are isolated from wilt infected leguminous crops of a Madhya Pradesh state and tested for their antagonistic activity against Fusarium (soil borne pathogen) which is expressed as a zone of inhibition in the culture plates. The seven strains are identified as Trichoderma viride, T. harzianum, T. asperellum, T. koningii, T. atroviride, T. longibrachiatum, an...
