| Se efectuó un ensayo en condiciones controladas utilizando hongos formadores de micorrizas arbusculares (HFMA) nativos, provenientes de un suelo rizosférico de Pennisetum clandestinum de la Universidad Nacional de Colombia (Bogotá), manteniéndolos en plantas de Brachiaria decumbens creciendo sobre sustrato arenoso suplementado con solución nutritiva. Se evaluaron diferentes tratamientos: plantas con inóculo de HFMA, plantas con Trichoderma harzianum, plantas con HFMA+T. harzianum y plantas control no inoculadas, con el fin de determinar las posibles interacciones entre dichos microorganismos, así como su efecto sobre el crecimiento de B. decumbens. La presencia de T. harzianum disminuyó la colonización radicular por HFMA, aunque no afectó la cantidad de... |

| Trichoderma harzianum inducting resistance to Zymoseptoria tritici. Septoria tritici blotch is endemic in the wheat growing cultivated areas of Argentina, which impacts in the crop yield. One management strategy is to use biocontrol agents. The objective of this work was to determine the effectiveness of Trichoderma spp. isolated from soils of different growing regions, as antagonist and characterize the T. harzianum effect throughout the proteolytic activity of the serine protease in the wheat plant. To determine the antagonistic capacities of Trichoderma spp. against Zimoseptoria tritici, wheat plants were grown from seeds coated with each of the ninety isolated Trichoderma. Antagonism was assessed 21 days after inoculation by the capacity of each... |

| Sugarcane bagasse was used as substrate for xylanase production by means of a strain of Trichoderma harzianum Rifai isolated from decaying Aspidosperma sp. (peroba) wood. The bagasse was washed, dried, milled and wetted with minimal salts medium and the cultures grown at 28 ± 2ºC for 7 days. Two extraction methods were tested for enzyme recovery: (A) Tween 80, 0.1% (v/v), in physiological saline, and (B) 50mM sodium acetate buffer, pH 5.0, under agitation (180rpm) for 15, 30 and 60min. After a single extraction, both extraction methods recovered an average of 15U/ml of xylanase activity, independent on the time of shaking. A second and third extraction recovered 10.4 and 6.6U/ml xylanase, respectively. The effect of volume size for extraction, and... |

| It was evaluated the effect of fungicides and the microbial control agent Trichoderma harzianum on the inhibition of the carpogenic and ascospore germination of Sclerotinia sclerotiorum. This study also evaluated the chemical, fungicidal and microbial control of white mold or Sclerotinia stem rot of soybean in the field. Three experiments were conducted, as follows: 1) inhibition of carpogenic germination of sclerotia, 2) inhibition of ascospore germination, and 3) control of Sclerotinia stem rot in a soybean crop under field conditions. The treatments evaluated were fluazinam, procymidone, iprodione, thiophanate-methyl, carbendazim, benzalkonium chloride + fluazinam, and T. harzianum. Procymidone resulted in an inhibition of 13.5% and benzalkonium... |
