Vesicatoria MLADEN ĐORĐEVIĆ *, JELENA DAMNJANOVIĆ, BOGOLJUB ZEČEVIĆ, RADIŠA ĐORĐEVIĆ, MILAN UGRINOVIĆ 1 Insitute for Vegetable Crops, Smederevska Palanka, Serbia * e-mail: mladendj1981@hotmail.com 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. Key words: Xanthomonas campestris pv. vesicatoria, alternative, control, copper, antibiotics, Bacillus subtilis, polyvinylpirolidon and bisumlated iodine complex INTRODUCTION Pepper (Capsicum annuum L.) is one of the most important vegetables in Serbia with long tradition of growing (Zečević et al., 2009, 2011).
