“…The use of beneficial micro‐organisms (notably fungi) seems to be a promising and environmentally sound method for biological control of phytopathogens. Among fungal Biological Control Agents (BCAs), Trichoderma species, in particular T. viride , T. harzianum , T. asperellum , T. atroviride and T. gamsii are among the most studied (Harman et al 2004; Kakvan et al 2013; Chen et al 2016; Daryaei et al 2016). They control fungal pathogens by different modes of action such as mycoparasitism, competition for space and nutrients, production of inhibitory compounds (antibiosis) and/or indirect stimulation of plant defences (Benítez et al 2004; Verma et al 2007).…”

Trichoderma atroviride as a promising biocontrol agent in seed coating for reducing Fusarium damping‐off on maize

et al. 2020

Aims: The objective of this work was to identify a fungal strain showing potential biocontrol abilities against two Fusarium damping-off agents and to test it as a Biological Control Agent (BCA) in maize seed coating under field conditions. Methods and Results: A collection of native fungal strains associated with maize in Belgium was screened for antagonistic potential against Fusarium avenaceum and Fusarium culmorum. The strain with highest biocontrol potential was identified as an endophytic Trichoderma atroviride BC0584. In greenhouse, it significantly improves the emergence of seedlings infected by F. avenaceum or F. culmorum pathogens. In most field trials carried out during the season 2017, it significantly increased the emergence rate of infected seedlings compared to untreated seeds. One slurriable powder formulation allows BCA conidia to survive over a 6-month storage period at 4°C. Conclusions: The fungal BC0584 strain is a promising BCA that could be an alternative to synthetic fungicides. It is adapted to local environmental conditions, is easily and cheaply produced and can be stored in a low-cost formulation. Significance and Impact of the Study: In Belgium, this is the first study to use a T. atroviride native strain against Fusarium damping-off on maize crop. Modes of action and required conditions for ensuring high biocontrol activity in the field have still to be investigated.

“…This study was part of a programme aimed to develop new knowledge of effects of growth conditions, to increase persistence and efficiency of the key agent T. atroviride LU132, which has been commercialized and to understand the factors which may influence conidium fitness (quantity and quality) for biological control formulations of conidia that are robust (long‐surviving) and active against target plant pathogens (Daryaei ; Daryaei et al . ,b,c,d). Although the effects of culture conditions on the quantity of conidia produced of this strain have been previously studied (Steyaert et al .…”

“…Similarly, previous studies have shown that T. atroviride LU132 outcompeted R. solani on dual plate assays (Daryaei et al . ,b,c,d,e). It has been suggested that Trichoderma metabolites contribute fungistatically to supress the growth and development of R. solani in soil or in agar dual cultures, which are proposed to be differentially modulated by NADPH oxidase (Dr Artemio Mendoza‐Mendoza 2014; personal communication).…”

“…atroviride LU132 were studied in agar plates (Daryaei et al . ,d,e). Fresh or dry conidia obtained from different culture‐growing conditions were also assessed (during 6 months of storage) for quantities of conidia produced and their quality, as indicated by germination and subsequent bioactivity against R. solani (see Daryaei et al .…”

Culturing conditions affect biological control activity ofTrichoderma atrovirideagainstRhizoctonia solaniin ryegrass

et al. 2016

This study is the first report on the effects of inoculum production conditions on conidium quality of Trichoderma to colonize and to maintain populations in host rhizospheres, and also the ability to promote plant growth and suppress a soil-borne disease. The results of these experiments provide new knowledge on how manipulation of culture conditions of T. atroviride LU132 can influence conidium fitness, as a basis for optimizing commercial production of the fungus as a biological control agent.
