Italy has a preeminent rank in kiwifruit industry, being the first exporter and the second largest producer after China.
However, in the last years kiwifruit yields and the global cultivated area considerably decreased, due to the pandemic spread of the bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa). Several climatic conditions and cultural practices affect the development of the bacterial canker.
With the emergence of this devastating disease, the use of pesticides rapidly increased and therefore the kiwifruit quality can be maintained only by ensuring agricultural practices that reduce the need of toxic xenobiotic compounds.
This research work focused on the impact of agricultural practices on disease development and spread.
High nitrogen fertilization, iron deficiency and water stress were related to more severe symptoms.
Open canopies allow a better irradiation, aeration, and penetration of phytosanitary treatments.
Synthetic gibberellins reduced disease incidence and severity in controlled conditions.
Finally, the preliminary guideline harmonizing the best cultural practices with the current disease control inputs is provided.
