Trichoderma species--opportunistic, avirulent plant symbionts.
TLDR
Root colonization by Trichoderma spp.Abstract:
Trichoderma spp. are free-living fungi that are common in soil and root ecosystems. Recent discoveries show that they are opportunistic, avirulent plant symbionts, as well as being parasites of other fungi. At least some strains establish robust and long-lasting colonizations of root surfaces and penetrate into the epidermis and a few cells below this level. They produce or release a variety of compounds that induce localized or systemic resistance responses, and this explains their lack of pathogenicity to plants. These root-microorganism associations cause substantial changes to the plant proteome and metabolism. Plants are protected from numerous classes of plant pathogen by responses that are similar to systemic acquired resistance and rhizobacteria-induced systemic resistance. Root colonization by Trichoderma spp. also frequently enhances root growth and development, crop productivity, resistance to abiotic stresses and the uptake and use of nutrients.read more

Formulations can affect rhizosphere colonization and biocontrol efficiency of Trichoderma harzianum SQR-T037 against Fusarium wilt of cucumbers
TL;DR: It is proposed that TFF treatment at SQR-T037 rate of 107 cfug−1 (i.e., 105 cfugen−1 soil after applied to soil) was the best formulation for controlling Fusarium wilt of cucumber.

Systemic resistance induced by rhizosphere bacteria
TL;DR: Rhizobacteria-mediated induced systemic resistance (ISR) is effective under field conditions and offers a natural mechanism for biological control of plant disease.

Microbial interactions and biocontrol in the rhizosphere
TL;DR: Multiple microbial interactions involving bacteria and fungi in the rhizosphere are shown to provide enhanced biocontrol in many cases in comparison with biocOntrol agents used singly.

Mechanisms Employed by Trichoderma Species in the Biological Control of Plant Diseases: The History and Evolution of Current Concepts.
TL;DR: Past research indicates that the mechanisms are many and varied, even within the genus Trichoderma, and in order to make the most effective use of biocontrol agents for the control of plant diseases, it must understand how the agents work and what their limitations are.

TL;DR: The demonstration that PGPR strains release different volatile blends and that plant growth is stimulated by differences in these volatile blends establishes an additional function for volatile organic compounds as signaling molecules mediating plant–microbe interactions.
