Polyvinylpirolidon and bisublimated iodine complex as an alternative in controlling bacterial spot of pepper Xanthomonas campestris pv. Vesicatoria

Abstract

The aim of this research was to test efficiency of polyvinylpirolidon and bisublimated iodine complex in controlling Xanthomonas campestris pv. vesicatoria. Efficiency of this complex has been compared to efficiency of biological pesticide Serenade, antibiotic Starner and copper pesticide Bakrocid S - 50. The trial included two treatments: (i) two hours before inoculation; (ii) four hours after inoculation and control inoculated only with the pathogen. Disease intensity (DSI) and efficiency has been observed after 14 days. The results showed that pesticide Vestal PVP-179 in treatment (i) had efficiency 77.23%, while in treatment (ii) had 72.28% which is close to the efficiency of other pesticides. The conclusion is that this pesticide could be used in controlling this pathogen.

Cilj ovog ogleda je bio da se testira efikasnost kompleksa polivinilpirolidona i bisublimiranog joda u suzbijanju Xanthomonas campestris pv. vesicatoria. Efikasnost ovog kompleksa poredila se sa efikasnošću biološkog preparata Serenade, antibiotika Starner i coppernog preparata Bakrocid S - 50. U ogledu su bila dva tretmana:(i) dva sata pre inokulacije; (ii) četiri sata posle inokulacije, i kontrolu koja je samo inokulisana patogenom. Nakon 14 dana vršena je ocena inteziteta oboljenja (DSI) i efikasnosti. Utvrđeno je da je preparat Vestal PVP-179 u tretmanu (i) imao efikasnost 77,23%, dok je u tretmanu (ii) imao 72,28% što je u granicama efikasnosti koje su imali drugi preparati. Možemo zaključiti da se ovaj preparat može koristiti u cilju suzbijanja ovog patogena.
