Sažetak
The aim of this work was to investigate the influence of the silicon foliar application on the intensity of olive damage caused by the settlement of jasmine moth (Margaronia (Palpita) unionalis Hubner) larvae, and the phenolic response of olive leaves. The field trail on two years old Leccino cv. olives was conducted, as a completely randomized design with two treatments (untreated control (Si-) and silicon treated plants (Si+)), during September and October of 2022. During the trial Si+ plants were foliarly treated five times at intervals of one week. After second treatment the larvae of four jasmine moth were settled on the apical buds of Si- and Si+ olives. Seven days after the last treatment, samples of young and old leaves for phenolic analyses were taken. Damaged leaves, apical buds and the number of pupae per plant were also counted. The results showed significant differences in the oleuropein concentration between Si- and Si+ leaves (6121 mg/100 g DW and 6914 mg/100 g DW, respectively). Comparing the percentage of damaged leaves and the percentage of damaged apical buds, there was no significant difference between Si- and Si+ olives. A significant difference was shown in the number of pupae per plant, namely, no pupae were found on Si+ plants, while an average of 0.3 pupae per olive was found on Si- plants. Due to our preliminary results further investigation of the silicon foliar application in protecting olives from the jasmine moth as well as other insects is needed.
