“…Gummy stem blight (GSB) is one of the most destructive diseases in cucurbits worldwide, especially for melon (Keinath, 2011;Keinath, 2015). In Brazil, GSB is one of the most damaging diseases in melon fields (Gasparotto, Vida, Tessmann, & Alves, 2011;Cardon et al, 2016). Its aetiologic agent is the fungus Didymella bryoniae, frequently leading to symptoms such as cankers, with gum exudation on the stem, rods and petioles, eventually leading to plant death.…”
