  • The relationships between plants and beneficial microorganisms in the rhizosphere (e.g. mycorrhizas, fungi and bacteria) are essential for root development, plant nutrition, and growth enhancement. The decline of agricultural soils fertility is due not only to the reduction of organic matter content, but expecially to the depletion of the edaphic microflora. Plant Growth Promoting Rhizobacteria (PGPR) have been proven to stimulate plant growth and the natural resistance towards diseases. Some bacterial bioformulations are available on the market for the use in agriculture. In this study, the effects of a new PGPR mixture (based on Pseudomonas spp. and Bacillus spp. strains) on plant growth, yield, and tolerance to pathogens of several horticultural crops, were evaluated. The experiments were conducted in a commercial orchard cultivated according to the organic farming system. Plants treated with water and the bioformulate Sublic© (Elep Biotechnologies SpA) were used as controls. The incidence of naturally occurring diseases caused by fungi and viruses was monitored. PGPR-treated plants were also monitored in a greenhouse and challenged for resistance/tolerance to selected pathogen infections by means of mechanical inoculations of pathogenic viruses and fungi. Treatments with the new developed PGPR mixture greatly enhanced plant growth and significantly anticipated the harvesting of some horticultural crops. The effectiveness of the new PGPR mixture on plant fitness and tolerance to viral and fungal diseases, as well as the differences with the commercial bioformulation, are also discussed. (literal)
