4 SUMMARY
The experimental field trial was carried out in the countryside of Centallo (province of Cuneo –
Northern Italy) from May 2019 to July 2019, in order to evaluate the efficacy and selectivity of
Anolyte (AcquAttiva®) applied on BIO pear to control Erwinia amylovora (ERWIAM).
Anolyte (AcquAttiva®) was been tested in comparison to organic standard control strategy (Amylo X+Vacciplant+Poltiglia Disperss). Disease symptoms were visible at 30/05/2019 but the disease pressure was very low and concentrated on the buds. Anolyte (AcquAttiva®) showed good efficacy to control disease, but efficacy evaluation was not completely verified because the disease pressure was very low. All treatments did not show any phytotoxicity symptoms on the crop. La prova sperimentale è stata condotta a Centallo (provincia di Cuneo – Nord Italia) da Maggio 2019 a Luglio 2019, al fine di valutare l’efficacia e la selettività di Anolyte (AcquAttiva®) per il controllo di Erwinia amylovora (ERWIAM). Anolyte (AcquAttiva®) è stata testata a confronto con una strategia BIO standard (Amylo X+Vacciplant+Poltiglia Disperss). I sintomi della malattia erano visibili al 30/05/2019, ma la pressione era molto bassa e concentrata sui germogli. Anolyte (AcquAttiva®) ha mostrato una buona efficacia nel controllo della malattia, ma la valutazione dell’efficacia non è completamente verificata in quanto la pressione della malattia era molto bassa. Tutti i trattamenti non hanno mostrato alcun sintomo di fitotossicità sulla coltura.

8.1 EFFICACY Efficacy evaluation was carried out counting the number of buds infected by ERWIAM. The buds infected was been removed on each plots. At first assessment Anolyte (AcquAttiva®) showed good efficacy to control disease, but Bio standard strategy showed higher efficacy (Chart 2, paragraph 10.3). The second assessment was carried out 14 days after first assessment and Anolyte (AcquAttiva®) showed good efficacy to control disease (Chart 3, paragraph 10.3). Successively, all assessments have not showed any deasease symptoms. La valutazione dell’efficacia è stata effettata contando il numero di germogli infetti da ERWIAM. I germogli infetti sono stati rimossi da ogni plots. Alla prima valutazione Anolyte (AcquAttiva®) mostrava una buona efficacia nel controllo della malattia, ma la strategia Bio di riferimento ha mostrato un’efficacia più elevata (grafico 2, paragrafo 10.3). Alla seconda valutazione effettuata 14 giorni dopo la prima, Anolyte (AcquAttiva®) ha mostrato nuovamente una buona efficacia nel contenimento della malattia (grafico 3, paragrafo 10.3). Successivamente, in tutte le valutazioni non sis ono riscontrati sintomi legati a ERWIAM.
8.2 PHYTOTOXICITY All assessments have not showed any phytotoxicity symptoms. Tutte le valutazionI non hanno mostrato alcun sintomo di fitotossicità.
