“Bois noir” incidence reduction by grafting recovered grapevine shoots

It was evaluated if grafting of recovered material on symptomatic and symptomless grapevines can have curative and preventive effects against the “bois noir” phytoplasma disease. Symptom observation and molecular detection of ‘Candidatus Phytoplasma solani’ were conducted on grafted and ungrafted grapevines. The percentage of symptomatic and infected plants was significantly reduced in grafted symptomatic grapevine, indicating that grafting of recovered shoots may have a curative effect.
