Trichoderma species are soil-borne filamentous fungi widely utilized for their many plant health benefits, such as conferring improved growth, disease resistance and abiotic stress tolerance to their hosts. Many Trichoderma species are able to produce the auxin phytohormone indole-3-acetic acid (IAA), and its production has been suggested to promote root(More)
Pheochromocytomas are functioning paragangliomas often presenting with paroxysmal hypertension due to catecholamine secretion. The preferential diagnostic workup includes urine and serum catecholamine measurements. Therapeutic management consists of pharmacologic cardiovascular manipulation and volume expansion with subsequent surgical resection. We have(More)
Trichoderma species form endophytic associations with plant roots and may provide a range of benefits to their hosts. However, few studies have systematically examined the diversity of Trichoderma species associated with plant roots in tropical regions. During the evaluation of Trichoderma isolates for use as biocontrol agents, root samples were collected(More)
Pellet and solid substrate formulations combined with a soil drench formulation of Trichoderma atroviride were evaluated under varying disease pressures in field trials to determine which formulation(s) provided the best control of the soil-borne disease onion white rot. Under low (11.8%) (average Area Under the Disease Progress Curve (AUDPC): 5.94%),(More)
Several members of the genus Trichoderma are biocontrol agents of soil-borne fungal plant pathogens. The effectiveness of biocontrol agents depends heavily on how they perform in the complex field environment. Therefore, the ability to monitor and track Trichoderma within the environment is essential to understanding biocontrol efficacy. The objectives of(More)
In this study we examined the influence of the ambient pH during morphogenesis on conidial yield of Trichoderma sp. "atroviride B" LU132 and T. hamatum LU593 and storage at low temperatures. The ambient pH of the growth media had a dramatic influence on the level of Trichoderma conidiation and this was dependent on the strain and growth media. On(More)
This is the first comprehensive survey of the species diversity of Trichoderma for a region within the temperate Southern Hemisphere. New Zealand makes an ideal target for such a survey because of the extensive historical collections of this genus from both native and human-modified ecosystems. From the 320 Trichoderma strains sequenced for the translation(More)
Trichoderma strains were tested for their ability to reduce the severity of root-knot nematode (RKN), Meloidogyne hapla galling on tomato roots. In initial glasshouse trials, under low levels of RKN infestation (1.1 eggs mL soil−1), Trichoderma strains applied as a conidial suspension reduced RKN-induced root galling by 42–88 %. When the nematode(More)
Members of the genus Trichoderma comprise the majority of commercial fungal biocontrol agents of plant diseases. As such, there is a wealth of information available on the analysis of their biocontrol potential and the mechanisms behind their superior abilities. This chapter aims to summarize the most common methods utilized within a Trichoderma biocontrol(More)
