This is attributable to the diverse metabolic capacity of these species and their aggressive competitive nature: fast growing, good secondary opportunists, producers of large quantities of spores, enzymes and antibiotics. All characteristics that make Trichoderma a powerful biocontrol agent. The aim of this work is to characterize physiologically, biochemically and biologically seven Trichoderma strains that have been isolated from different locations in Costa Rica, and are widely used, particularly in this country, against various plant pathogens. For all tests, the strains were grown in two temperature regimes, at 25\u00B0 and 30\u00B0C, and compared to T. atroviride P1 strain which was used as control. The physiological characterization was performed by growing the different Trichoderma strains on PDA (potato-dextrose agar) and agarized SM (minimal salt medium) containing sucrose as the only carbon source. Measurements were conducted on the mycelial growth, time to sporulation and the quantity of spores produced. Trichoderma strains Bulgvir, Harz, TF, PB17 showed a mycelial growth and quantity of spores production higher than P1 when grown at 30\u00B0C; no differences were observed at 25\u00B0C. Culture filtrates were produced from Trichoderma strains grown in liquid SM plus 1% sucrose at the tested temperatures, and biochemical analysis was performed on endochitinase, exochitinase, glucanase\nand xylanase activities. Trichoderma strains ZS, TF, PB17 had endochitinase and exochitinase activities higher than P1, and glucanase and xylanase activity similar to P1 when the strains were grown at 30\u00B0, while no differences were observed at 25\u00B0C. In vitro confrontation assays were performed on SM agar plates with each isolate against the pathogens Rhizoctonia and Botrytis. At 30\u00B0C, strains Bulgvir, Harz, Exc, TF, PB17 were able to reduce the growth of the pathogens Rhizoctonia and Botrytis more effectively than P1. Biological activity of the culture filtrates was tested on Botrytis spores. The antifungal activity was similar to P1 for the culture filtrates of Bulgvir, Harz, TF, PB17 strains in the inhibition of both Botrytis spore germination and germ tube elongation. In correspondence to the climatic zone of origin, the tested strains from Costa Rica exhibited the best fitness, enzyme production and antifungal activity when grown at the higher temperature of 30\u00B0C instead of 25\u00B0C."^^xsd:string ; pubblicazioni:affiliazioni "Istituto per la Protezione delle Piante, CNR, Portici (NA)"^^xsd:string ; pubblicazioni:titolo "Characterization of novel Trichoderma strains adapted to high temperature and effectively applied in Central America for disease control."^^xsd:string ; prodottidellaricerca:prodottoDi istituto:CDS064 , modulo:ID5881 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA8709 , unitaDiPersonaleEsterno:ID6644 , unitaDiPersonaleEsterno:ID1470 .
