Resumen
Descripción
Avocado crop production in Colombia requires establishing environmentally friendly and inexpensive measures for wilt disease management, whose main causal agent is. Soil microorganisms use is an option for improving nutrition and health in Persea americana , looking to be more competitive in order to face the free trade agreements and to exploit the full export potential for this fruit. Understanding the complexity of the soil microbiota system, due to its great diversity and different ecological relationships that govern it, this study was designed to evaluate under greenhouse conditions the effect of Trichoderma sp, Glomus fasciculatum and Pseudomonas sp. isolates, on P. americana seedling development inoculated and non-inoculated with P. cinnamomi . Results found in this work suggest that G. fasciculatum and Pseudomonas sp., alone or in combination increase avocado seedling development, meanwhile Trichoderma sp. showed the best results in reducing the wilt disease progress on P . cinnamomi -inoculated plants. Soil microorganisms have a large potential for P. Americana development and pathogen protection, but it is necessary to understand all possible relationships in order to strengthen their use as biofertilizers and biocontrol agents.
