The project for spreading techniques to optimize and improve the management of the main fungal diseases in table grapes, such as downy mildew, powdery mildew, and grey mould, continues. As for the previous editions, the need to add the grey mould as a focus for 2022 has emerged from the requests of the producers of quality table grapes. Therefore, the location for the 2022 edition of the Table grape fungicides Campo Demo will be a vineyard in the Palagiano countryside, of the “Italia” variety, which is suited for a longer commercialization window thanks to techniques that extend the time the bunches can stay on the plant and their subsequent cold storage in specialized structures.
The claim that will be evaluated is the increase in shelf-life.
The tests will be conducted both in the field and in cold storage.
In the field, the degree Brix, the bunch weight and the hardness will be evaluated. In addition, the total acidity will be analyzed.
In storage, instead, the weight, the drying/desiccation of the rachis and the hardness will all be evaluated at 0, 15, 30 and 45 days.
Evaluation of several products and strategies for controlling downy mildew and powdery mildew on table grapes.
Strategies and chemical and biological products have been tested to evaluate their effectiveness on Plasmopara vitivola and Uncinula necator on table grapes.
