Characterization of Colletotrichum strains associated with olive anthracnose in Sicily
2022
Anthracnose caused by Colletotrichum spp. is the most damaging olive fruit disease in many countries, including Italy. This disease has been sporadically detected in Sicily, but new agronomic practices can increase risk of olive anthracnose in this region. An etiological study of the disease focused on local olive cultivars growing at the International Olive Germplasm Collection (IOGC) in Villa Zagaria, Enna, Sicily has been undertaken. During 2018 and 2019, 137 Colletotrichum strains were isolated from olives. Colony morphology, conidium characteristics, and multilocus sequence analyses aided identification of three species: C. acutatum (affecting 70% of symptomatic olives), C. gloeosporio…
Effectiveness of spinosad and mineral oil for control of Grapholita funebrana Treitschke in organic plum orchards
2012
An experiment was conducted in an organic plum orchard in Sicily to evaluate the damage caused by the plum moth Grapholita funebrana (Treitschke) to three plum cultivars (Angeleno, Friar, and Stanley) and to evaluate plum moth control provided by mineral oil applied every 20 days (Moil), spinosad applied every 10 days (S10), or spinosad and mineral oil applied alternately (S/Moil). Treatment application began when eggs were first observed on fruits. S10 and S/Moil effectively reduced plum moth damage on all cultivars but Moil did not. Plum moth infestation was significantly lower on Stanley than on Friar and Angeleno.
