Descripción
This study quantified Trichodermain 16 tobacco fields fromnorthwestern Argentina (NWA). The Trichoderma population was higher in seven of the soils studied (V1, V2, R2, R5, R6, SA2, and CH2), three of which are suppressive soils. HighestTrichoderma propagules were associated with loam texture, high organic matter, high aggregate stability, and low pH. Thirty-nine Trichoderma spp. isolates were obtained and screened for in vitro antagonism against Rhizoctonia solani (AG2-1, AG4-HGI and AG4-HGIII) isolated from tobacco. Th15, Th21, Th28, Th40, Th45 and Th51, were identified as T. afroharzianum, and Th14 and Th27, were T. rifaii and T. virens, respectively. This is the first report of T. afroharzianum, T. rifaii and T. virens from soils of NWA. Th14, Th15 and Th51 reduced the infection of R. solani AG4 and promoted tobacco growth.
