Descrizione principale

Esca is a grapevine disease caused by several different fungi such as Phaeomoniella chlamydospora (P. chlamydospora) and Phaeoacremonium aleophilum (P. aleophilum). In the last years this disease has become a worldwide problem. Membranes from cellulose acetate (CA) and cellulose acetate/polyethylene glycol (CA/PEG) containing chemical fungicide - 5-chloro-8-hydroxyquinolinol (5-Cl8Q) were prepared by electrospinning and were studied as suitable candidates for plant protection against fungi. Several methods including scanning electron microscopy (SEM), IR spectroscopy, water contact angle measurements and UV-VIS spectroscopy were utilized to characterize the obtained fibrous materials. The antifungal activities of the obtained materials against P. chlamydospora and P. aleophilum were studied as well. Тhe present study reveals the possibility to use electrospun polymer membranes containing 5-Cl8Q to impede the penetration and growth of P. chlamydospora and P. aleophilum.
