The research work carried out aimed at verifying the efficacy of Trichoderma-based products on the fertility maintenance in vineyard soils, in case of replanting. The presence of a hypofertile horizon, in fact, can cause problems in the engrafting of rooted cuttings and a slowing down in their vegetative development. The trial was carried out at the experimental farm of CREA − Research Center for Viticulture and Enology of Arezzo, during the setting up of a new Sangiovese vineyard. Rooted grafts treated with three different formulations containing some Trichoderma spp. strains were planted, considering an untreated negative control. In addition, treatments with the same formulations were repeated in the 2014-2016 three-year period, by spraying the soil, with an injector pole. Every year the shoot length and the pruning wood weight were evaluated, as well as the presence/absence of Trichoderma spp. on the root systems. Moreover, in 2016 the photosynthetic efficiency of the vines was verified. The presence of Trichoderma spp. within the rhizosphere of the vines treated was stable over time; the differences found between treated and untreated thesis were considerable, while only minor differences emerged among the plants subjected to the three different treatments. According to the results obtained, the application of Trichoderma-based products can be considered a valid practice to be used during vineyard implantation in case of difficult edaphic conditions.
