Resumen:
The implementation of management practices that increase the natural populations of potential biocontrol agents may be a useful
strategy in the control of diseases caused by soilborne fungi in peanut. The effects of rotation crops (maize, soybean, and peanut) and
tillage systems (no tillage, reduced, and conventional tillage) on potential biocontrol agents and on the incidence of soilborne diseases
were evaluated in two long-term field experiments at two sites located in the north and south regions of the peanut production area in
Argentina. Native populations of actinomycetes, Trichoderma spp., and Gliocladium spp. were quantified from soil samples; the incidence
of diseases caused by soilborne fungi was determined at peanut harvest. When maize was the preceding crop and crops were under
conservation tillage, populations of biocontrol agents were higher in both trials. However, the relationship between cultural management
and the incidence of root rot (strains of Fusarium solani) varied between the two field experiments, rot being lower when maize was the
previous crop and peanut was under no tillage, and higher under the same management conditions at the other location. The
quantification of native potential biocontrol agents (PBA) could be employed as a tool to determine the appropriate management
strategies to be implemented for a sustainable control of peanut soilborne diseases.
