phaseolina, and showed higher PIE of 91.02% and 91.50% of PIC compared to other isolates, which had an inhibitory effect with respect to the fungal pathogen in the range of 65.09 to 84.69% for the PIE and 67.33 to 77.48 for the PIC.Д«iological control fungus taxonomy in vitro pathogens inhibition of sporlation growth of inhibition. crassum 06141 was the most effective in controlling M. phaseolina, depending on the percent inhibition of sporlation (PIE) and growth inhibition (PIC). are most effective as a seed treatment, to prevent death from other fungi in emerging and young plants in this role, Trichoderma can offer improvement over chemical seed treatments. As a decomposer, Trichoderma fungi can be used to help speed up compost piles.

Variability in vitro was found in the control exercised by each isolated against M. Several strains of Trichoderma have been developed as biocontrol agents.

longibrachiatum (SamГЎn Mocho) respectively. mortality biological control agent dagger nematodes. Twelve isolates were obtained, nine were related to the species Trichoderma harzianum (06146, 06143, FTSC05, JCFA05, 06153, I9, J10, and San Miguel 06151) and the remaining isolates belong to the species T. In vitro investigations on the biological control of Xiphinema index with Trichoderma species. To do this, the isolates were grown for 3-4 d and 6-8 d being examined macro and microscopically. The samples were processed using the method of agar plate dilution, the isolates obtained were purifi ed on PDA, its determination was performed at the species level. The objective of this research was to identify Trichoderma species isolated from soil samples of bean growing areas, corn, tomato and sorghum in Aragua, Carabobo and Guarico and antagonistic value was found in the control of Macrophomina phaseolina.

Show full abstract widely used as biocontrol agent against different kinds of plant pathogens. ISSN 0002-192X.ДЇungi of the genus Trichoderma deserve maximum attention as biocontrol agents because they demonstrated their high antagonistic power plant pathogens. Among various types of species being used as biocontrol agents, Trichoderma is. Importance of Trichoderma species for control of Macrophomina phaseolina in agricultural areas of Aragua state, Venezuela. atroviride isolates were selected for field assessment as biocontrol agents of soil-borne pathogens of pasture species.SALAZAR, Luis A et al. On the basis of these results for both disease reduction and growth promotion, four T. Seedling growth (shoot and root fresh weight/plant) of the three pasture species was significantly increased by one or more T. However, for all three pasture species, some Trichoderma isolates reduced seedling emergence. ultimum, white clover (Trifolium repens L.) emergence was increased by 25-42% by one isolate of T. trifoliorum was significantly increased by two T. Red clover (Trifolium pratense L.) emergence in the presence of S.

virens, with the increase depending on growing medium and amount of pathogen inoculum. atroviride and by 35- 212% by the isolate of T. solani, perennial ryegrass (Lolium perenne L.) emergence was increased by 60-150% by two isolates of T. virens) were chosen for assessment in pot experiments. Following dual culture assays, nine Trichoderma isolates (five of T. The potential for biocontrol of these pathogens by Trichoderma fungi was evaluated. Soil-borne plant pathogens such as Rhizoctonia solani (Kuhn), Pythium ultimum (Trow) and Sclerotinia trifoliorum (Eriks) can reduce grass and forage legume establishment.
