Fusarium circinatum, a fungus that causes pitch canker disease, has been present in Europe since at least 2003, when it was detected in northern Spain and found to be producing severe damage in tree nurseries and pine plantations. In this study, we tested a method of biological control of the disease with Trichoderma viride, a fungal species successfully used against many other pathogens. In vitro and in vivo assays were carried out to test the efficacy of this antagonist in controlling F. circinatum. The T. viride isolate exerted a significant effect on the growth of F. circinatum in the in vitro assay, reducing the length of the pathogen colony by half. However, although we tested three different concentrations of the T. viride spore solution, no clear conclusions were obtained with regard to the effects on the Pinus radiata seedlings. To our knowledge, this is the first study carried out with the aim of using Trichoderma spp. to control pitch canker disease.

“…They further observed that treatment with T. harzianum T39 increased the expression of defense-related genes [48] which induced resistance in the plants. However, this effect was more pronounced in tissues closer to the site of antagonist application than in tissues which were distant, and this was reflected in a higher disease control near the site of application as compared sites which were distant.…”

Among the group of ubiquitous soil inhabiting fungi, Trichoderma species are of considerable commercial importance due to their ability to suppress many plant pathogenic fungi. They have been widely studied and employed for management of root and seedling diseases of many crops since decades. In recent years they are also being utilized for minimising diseases of foliar plant parts, especially to supress grey mold caused due to infections of Botrytis cinerea and powdery mildews on a number of crops. They also express potential to control downy mildews and have improved the shelf life of grapes. Out of the eighty-nine species of Trichoderma, a number of species exhibit the bio-control activity. The destruction of host hyphae and protoplasm by the various lytic enzymes and toxic volatile and non-volatile compounds produced by these species are the major mechanism of bio-control; apart from deactivation of pathogen enzymes and induction of systemic resistance in host plants. However, significant differences in antagonistic potential among isolates even from the same species from the same niche is observed; and hence selection of a strain with wide host range and environment adaptability becomes a key issue for sustainable biological control.

“…Trichoderma spp., an antagonistic fungus well-known as biocontrol agent against several soil borne plant pathogens (Harman et al, 2004;Perazzolli et al, 2011), is also involved in plant growth and yield enhancing (Rudresh et al, 2005;Verma et al, 2007;John et al, 2010). Equally, arbuscular mycorrhizal fungi (AMF), a worldwide occurring plant-fungi association, colonize roots of soybean, increase functional soil volume and promote plant growth through improvement of plant nutrient uptake, especially phosphorus (Marschner and Dell, 1994;Ortas, 2010); Farzaneh et al (2009).…”
