TLDR
Three isolates of Trichoderma spp, effective in reducing sclerotial germination of isolate Sr-1, also prevented sclerosis germination in four out of five additional S. rolfsii isolates studied and helped protect bean seedlings against the pathogen in the greenhouse.Abstract:
Ten isolates of Trichoderma spp were examined for their ability to antagonize growth and to parasitize mycelium of Sclerotium rolfsii (Sr-1) on agar media, to inhibit germination of sclerotia of S. rolfsii on natural soil plates and to sporulate on the sclerotia, and to protect bean seedlings against the pathogen in the greenhouse. A high negative correlation ( r = −0.844) was observed between plant stand in the greenhouse and sclerotial germination on soil plates but not with antagonism on agar plates. Three isolates of T. harzianum (Th-7, Th-20, WT-6) and one of T. hamatum (TRI-4) were especially effective in reducing sclerotial germination and controlling disease in the greenhouse. Three isolates of Trichoderma spp (WT-6, TMP, and TRI-4), effective in reducing sclerotial germination of isolate Sr-1, also prevented sclerotial germination in four out of five additional S. rolfsii isolates studied.read more

Effect of media on growth and interactions between a range of soil‐borne glasshouse pathogens and antagonistic fungi
TL;DR: Responses to the media appeared to be related both to inherent properties of the fungi and to their natural ecological behaviour and the significance of in vitro assays in screening systems for biological control agents of soil-borne plant pathogens is discussed.

Arabidopsis thaliana as a model system for testing the effect of Trichoderma volatile organic compounds
TL;DR: VOCs emitted by T. viride have growth promoting effects on A. thaliana in the absence of direct physical contact, and isobutyl alcohol, isopentylcohol, and 3-methylbutanal were most abundant.

Fungal antagonists of the plant pathogen Rhizoctonia solani: selection, control efficacy and influence on the indigenous microbial community.
TL;DR: In this first assessment study for Trichoderma, it was shown that the pathogen and the vegetation time had much more influence on the composition of the microbiota than the BCA treatment.
BookDOI
Microbial-mediated Induced Systemic Resistance in Plants
TL;DR: This chapter surveys the reports of recent investigations involving rhizospheric microorganisms especially plant growth-promoting rhizobacteria and arbuscular mycorrhizal fungi that could change the production and accumulation of plant pharmacologically active compounds.
