AB  - Bacterial spot caused by Xanthomonas euvesicatoria is one of the most devastating pepper diseases in Serbia. Questionable seed quality, climatic conditions, and frequent irrigation during summer favour the disease occurrence and spread. The available management practices do not provide adequate disease control. Therefore, development of alternative and more sustainable disease management strategies is needed. Integration of classical and biological treatments could be an effective, environmentally safe option for reducing pepper bacterial spot severity. In order to develop an efficient integrated disease management program, we studied efficacy of biocontrol agents (bacteriophage strain K Phi 1 and two strains of Bacillus subtilis AAac and QST 713), systemic acquired resistance (SAR) inducer (acibenzolar-S-methyl - ASM), a commercial microbial fertilizer (Slavol), copper based compounds (copper hydroxide and copper oxychloride) in combination with or without mancozeb, and antibiotics (streptomycin sulphate and kasugamycin). They were applied as single treatments in two separate field experiments. Based on the single treatment efficacy, various combinations of the treatments were chosen for further testing in three separate field experiments. Additionally, we evaluated potential negative effect of ASM on pepper growth and yield in the growth chamber experiment. All the tested single treatments significantly reduced disease severity compared to the inoculated control (IC), except microbiological fertilizer and the antagonistic strain AAac. Integration of copper hydroxide, ASM and bacteriophages was the most efficient treatment, reducing the disease intensity by 96-98%. The results indicated that this combination may be an adequate alternative program for control of pepper bacterial spot.

AB  - Xanthomonas euvesicatoria phage K Phi 1, a member of Myoviridae family, was isolated from the rhizosphere of pepper plants showing symptoms of bacterial spot. The phage strain expressed antibacterial activity to all X. euvesicatoria strains tested and did not lyse other Xanthomonas spp., nor other less related bacterial species. The genome of K Phi D1 is double-stranded DNA of 46.077 bp including 66 open reading frames and an average GC content of 62.9%, representing the first complete genome sequence published for a phage infecting xanthomonads associated with pepper or tomato. The highest genome similarity was observed between phage K Phi 1 and the Xanthomonas oryzae pv. oryzae specific phage OP2. On the other hand, when compared with other members of the genus Bcep78virus, the genome similarity was lower. Forty-four (67%) predicted K Phi 1 proteins shared homology with Xanthomonas phage OP2, while 20 genes (30%) were unique to K Phi 1. Phage K Phi 1, which is chloroform resistant and stable in different media and in the pH range 5-11, showed a high titer storage ability for at least 2 years at +4 degrees C. Copper-hydroxide and copper-oxychloride reduced phage activity proportionally to the used concentrations and the exposure time. UV light was detrimental to the phage strain, but skim milk plus sucrose formulation extended its survival in vitro. The phages survived for at least 7 days on the surface of pepper leaves in the greenhouse, showing the ability to persist on the plant tissue without the presence of the host bacterium. Results of three repeated experiments showed that foliar applications of the unformulated K Phi 1 phage suspension effectively controlled pepper bacterial spot compared to the standard treatment and the untreated control. The integration of the phage K Phi 1 and copper-hydroxide treatments resulted in an increased efficacy compared to the copper-hydroxide alone.

AB  - Bacterial spot caused by Xanthomonas euvesicatoria is considered one of the most important diseases of pepper in Serbia. In order to control this disease, copper based compounds (copper hydroxide, copper oxychloride, copper hydroxide + mancozeb, copper oxychloride + mancozeb), antibiotics (streptomycin sulfate and kasugamycin), resistance inducer (acibenzolar-S-methyl), antagonistic bacteria Bacillus subtilis (strains QST 713 and AAac), bacteriophage (strain K Phi 1) and one commercial microbial fertilizer, were tested for efficacy and compared to untreated control. The experiments were carried out in a greenhouse and climatic chamber conditions. Plants were inoculated with X euvesicatoria strain KFB 13 (10(8) CFU mL(-1)) using hand-held sprayer. Results of three experiments showed that all treatments except microbiological fertilizer significantly reduced intensity of bacterial spot symptoms compared to the untreated control. The most efficient treatment was acibenzolar-S-methyl reducing disease severity 93-97%. There was no statistically significant difference in efficacy of this treatment and copper hydroxide, copper oxychloride, copper hydroxide + mancozeb, copper oxychloride + mancozeb, streptomycin sulfate, kasugamycin and antagonistic strain QST 713 treatments. Application of antagonistic strain AAac and bacteriophage K Phi 1 significantly reduced disease intensity but less than the first group of treatments. Bacteriophage K Phi 1 (78-85% rH) was more effective in the climatic chamber compared to the efficacy (38% rH) in the greenhouse experiments.

AB  - During the summer of 2014, watermelon producers in the north of Serbia (Srem district), observed the occurrence of irregularly shaped, water-soaked lesions on mature watermelon fruits indicating possible bacterial nature of the disease. Bacteria were isolated from symptomatic samples and identified as Acidovorax citrulli, previously described as a causal agent of bacterial fruit blotch. In the past few years, this pathogen caused considerable damage to the watermelon industry of the United States where, in some commercial production sectors, the loss of marketable fruit reached 90%. In Serbia, it is considered a quarantine pathogen and was not recorded until 2014.

AB  - In search for an alternative to chemical control of fire blight, we isolated seven bacteriophages specific to E. amylovora. Three phages were isolated from water, three from symptomless pear leaves and one from apple leaves with characteristic fire blight symptoms. Host-range studies showed that the phages differed in the ability to lyse 40 strains of E. amylovora isolated in Serbia. Based on its lytic activity, phage Phi Ea2 was chosen for further study of biological control potential in pear and apple blossom bioassays. A phage suspension of 10(8) PFU/ml was applied on blossoms either 2 h before, 2 h after or at the same time of inoculation. In three fully replicated bioassay experiments, application of host-specific phages 2 h before inoculation and at the time of inoculation significantly reduced fire blight symptom development compared to untreated control. However, disease reduction was not significant when phages were applied 2 h after inoculation.

AB  - Bacterial spot, caused by bacteria that belong to Xanthomonas complex, is one of the widespread and economically important disease of pepper and tomato. Growing resistant genotypes, use of treatments based on copper compounds or streptomycin do not provide efficient control of this disease due to the appearance of new races of bacteria and development of strains resistant to antibiotics and copper compounds. Pepper and tomato producers do not have adequate resources for pathogen control since standard bactericides are not effective enough if weather conditions are favorable for the disease development.

Growing resistant genotypes, use of treatments based on copper compounds or streptomycin do not provide efficient control of this disease due to the appearance of new races of bacteria and development of strains resistant to antibiotics and copper compounds.

AB  - Bacterial spot, caused by either Xanthomonas euvesicatoria (Xe-Group A), X. vesicatoria (Xv-Group B), X. perforans (Xp-group C) and X. gardneri (Xg-Group D), formerly known as X. campestris pv. vesicatoria, is considered one of the most common pepper and tomato diseases in Serbia. So far, 11 physiological races of X. euvesicatoria bacterium were described around the world. However, four of them (P1, P3, P7, P8) have been recorded in Serbia, predominating being P8. The aim of this study was to examine the sensitivity of the 11 pepper genotypes: HS-2, Amfora, Plamena, Anita, Novosađanka, Palanačka babura, Palanačko čudo, Slonovo uvo, Brillant F1, Bihar F1 and Boni to X. euvesicatoria (RKFB 263), race P8. The experiments were carried out in a greenhouse. Pepper plants, with five fully expanded leaves, were artificially inoculated by dipping into the bacterial suspension, concentration of 106 cfu/ml and 108 cfu/ml, for 10 seconds. Early Calwonder (ECW) was used as susceptible control genotype, and its isogenic line ECW-20 withBs2 resistance gene as a resistant control. Experiments were organized as randomized block design with four replications, with five plants in each repetition. The intensity of infection was assessed by Horsfall - Barratt (HB) scale 7 and 14 days after inoculation. According to the results, pepper genotypes showed various degree of susceptibility to X. euvesicatoria (P8) differentiating into significantly different groups. Among the tested cultivars, Bihar F1 showed the highest degree of resistance to the pathogen, while all the other genotypes showed various degrees of sensitivity compared to the controls. Considering that most of the studied genotypes were sensitive to X. euvesicatoria (P8), with exception of the isogenic line ECW-20 with Bs2 resistance gene, transfer of this gene into commercial varieties of pepper would be a significant contribution to control of this economically important disease.

Cilj ovog rada bio je proučavanje osetljivosti 11 odabranih genotipovapaprike: HS-2, Amfora, Plamena, Anita, Novosađanka, Palanačka babura, Palanačko čudo, Slonovo uvo, Brillant F1, Bihar F1 i Boni, prema rasi 8 X. euvesicatoria. Kao osetljiva prema svim rasama patogena korišćena je sorta Early Calwonder (ECW), a kao nosilac gena otpornosti Bs2 prema genu avirulentnosti patogena (avrBs2) njena izogena linija ECW-20. Izvedena su dva ogleda, a za veštačku inokulaciju biljaka paprike pripremljene su suspenzije bakterija koncentracije 106 cfu/ml i 108 cfu/ml soja X. euvesicatoria (RKFB 263), rase P8. Veštačka inokulacija biljaka paprike izvedena je u stadijumu šest potpuno razvijenih listova, metodom potapanja biljaka. Ogledi su postavljeni po potpuno slučajnom blok rasporedu u četiri ponavljanja sa po pet biljaka u svakom ponavljanju. Intenzitet zaraze ocenjen je po Horsfall - Barratt (HB) skali 7 i 14 dana nakon inokulacije. Proučavani genotipovi paprike ispoljili su različit stepen osetljivosti prema bakteriji X. euvesicatoria. Nakon ocena intenziteta zaraze u oba ogleda izdvojile su se statistički značajno različite grupe. Samo je hibrid Bihar F1 ispoljio određeni stepen otpornosti prema bakteriji, dok su svi ostali proučavani genotipovi pokazali viši ili niži stepen osetljivosti u odnosu na kontrolne sorte. Obzirom da se većina proučavanih genotipova pokazala kao osetljiva prema prouzrokovaču bakteriozne pegavosti, kao i da postoji izolovan gen otpornosti prema najzastupljenijoj rasi patogena u nas, njegov transfer u komercijalne sorte paprike bio bi značajan doprinos kontroli ovog ekonomski važnog oboljenja.

AB  - During spring and summer of 2008, 101 bacterial strains was isolated from the diseased pepper leaves collected from different pepper growing areas in the Republic of Serbia. The aim of this research was to characterize the isolated strains and determine their taxonomic position according to the most recent nomenclature. Pathogenic, biochemical and physiological characteristics of isolated bacteria were tested using standard bacteriological tests. The pathogen races were determined according to the reaction of differential varieties of Early Calwonder (ECW), their isogenic lines (ECW-10R, ECW-20R, ECW-30R) and Capsicum pubescens. The sensitivity of strains to bactericides was studied in vitro by culturing bacteria on sucrose pepton agar (SPA) plates, amended with filter-sterilized aqueous solution of streptomycin and kasugamycin (50, 100, 200 ppm) or copper-sulphate (100, 200 ppm). Based on pathogenic, biochemical and physiological characteristics, the investigated strains belonged to Xanthomonas euvesicatoria. The reaction of pepper differential varieties indicated that these strains belonged to pepper races P1, P3, P7, P8. Streptomycin resistant strains were not detected, but 6 strains were resistant to kasugamycin (50 ppm) and 13 strains to copper-sulphate (200 ppm), indicating bacterial resistance development.
AB  - Tokom 2008. godine prikupljeni su uzorci obolelog lišća paprike sa simptomima bakteriozne pegavosti iz različitih lokaliteta Republike Srbije. Izolacijom iz zaraženih listova dobijen je 101 soj bakterija. Cilj ovog rada je proučavanje odlika i identifikacija izolovanih sojeva bakterije u skladu sa najnovijom nomenklaturom. Patogene i biohemijsko-fiziološke karakteristike sojeva proučene su korišćenjem standardnih bakterioloških testova. Određivanje fizioloških rasa bakterijske populacije izvršeno je na osnovu reakcije diferencijalnih sorti paprike Early Calwonder (ECW), njenih izogenih linija (ECW-10, ECW-20 ECW-30) i reakcijom sorte Capsicum pubescens. Proučena je osetljivost sojeva u in vitro uslovima na streptomicin, kasugamicin i bakar-sulfat. Rezultati proučavanja biohemijsko-fizioloških odlika sojeva ukazuju da naši sojevi pripadaju genetičkoj grupi 'A', odnosno vrsti Xanthomonas euvesicatoria. Proučavani sojevi, takođe, predstavljaju heterogenu populaciju u kojoj su zastupljene četiri fiziološke rase bakterije X. euvesicatoria (P1, P3, P7, P8). Sojevi rezistentni na streptomicin nisu detektovani ovim istraživanjima. Otpornost na 50 ppm kasugamicina utvrđena je kod 6 sojeva, a 13 sojeva je bilo otporno na 200 ppm bakar-sulfata. Prikazani rezultati ukazuju na opasnost od razvoja rezistentnosti bakterija na ova jedinjenja.
