A total of 26 native strains of Trichoderma were isolated from soil samples growing as­paragus (located in the Agroindustrial company Camposol SA, Chao, Peru) and 6 stra­ins were selected based on their growth rate and number of spores, within you stra­in were identified Trichoderma asperellum, Trichoderma harzianum and Trichoderma atroviride, these presented controlling activity Meloidogyne sp. both in vitro and under greenhouse conditions. These strains were isolated Pope Sucrose Agar (APS) incubated at 25  0.1 ° C for 7 days. In vitro tests were performed on water agar (AA) 1.5%, while in greenhouse tests nine treatments (T) with isolates were performed. Of the nine treat­ments, there are three control groups, at the T1 was inoculated only Meloidogyne sp. in another T2 it was not inoculated with Meloidogyne sp. and T3 Oxamyl (990ppm) was inoculated. While the other treatments ...
