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  - The aim of this study was to find an optimal way of tomato drying in a tunnel type dryer, in order to achieve the lowest possible losses in nutritive value of dried tomato products. Domestic variety of tomato (SP-109) was used in this research. Drying was performed in three ways, applying five temperature regimes, as follows: cocurrent system (variant 1 at 70-80 oC; variant 2 at 90-75 oC), countercurrent system (variant 1 at 55-65 oC, variant 2 at 65-75 oC) and combined system (85-55 oC and 55-65 oC). In these systems, the kinetic of changes in nutritive value of tomato fruits was monitored by measuring the content of carbohydrates, lycopene and vitamin C. Different influences of temperature regimes on nutritive value of dried tomato were observed at the level of statistical difference (LSD 0.05; 0.01) in the researched systems. Cocurrent system was statistically significant for differences in temperature modes (variant 1 and variant 2). Monitoring of the tomato drying kinetics showed that, in all variants, period of constant drying rate lasted about 3.5 h and that the total drying was the fastest in parallel cocurrent flow of non-saturated hot air and material. The content of total carbohydrates in tomato was dependent on the temperature regime of the tested drying systems. The carbohydrate content obtained in tomato samples dried at lower temperatures was higher compared to the values observed in the samples dried at higher drying temperatures. Significant losses of vitamin C were determined in all drying systems. The lycopene content under all experimental conditions generally showed a tendency to decrease slightly. Comparing its content in dry and fresh tomato fruits, the loss ranged from 4.94% to 19.98% but did not reach the significant level as the occurrence remained below 95% of cases.
AB  - Cilj ove studije bio je pronalaženje optimalnog načina sušenja paradajza u tunelskom tipu sušara kako bi se smanjili gubici vrednosti nutritijenata kod sušenog proizvoda paradajza. U ovom istraživanju korišćena je domaća sorta paradajza (SP-109). Istraživanje je izvedeno u tunelskom tipu sušara na tri načina u pet temperaturnih režima. Sušenje je izvedeno u sistemu paralelnog (varijanta 1 na 70-80 oC, varijanta 2 na 90-75 oC), suprotnosmernom (varijanta 1 na 55-65 oC, varijanta 2 na 65-75 oC) i kombinovanog sistema strujanja vazduha (85-55 oC i 55- 65 oC). U ovim sistemima sušenja praćena je kinetika promena nutritivnih vrednosti ploda paradajza: sadržaj ugljenih hidrata (%), likopena i askorbinske kiseline (vitamin C). Utvrđeni su različiti uticaji temperaturnih režima na nivou statističke razlike (LSD 0.05; 0.01) ispitivanih sistema za nutritivnu vrednost sušenog paradajza. Paralelni sistem je bio statistički značajan za razlike u varijanti temperature 1 i varijanti 2. Prateći kinetiku sušenja paradajza utvrđeno je da u svim varijantama period konstantnog sušenja traje oko 3,5 časa i da je za ukupno sušenje najbrži paralelni protok toplog vazduha i materijala. Sadržaj ugljenih hidrata u uzorcima paradajza koji su sušeni na nižim temperaturama bio je veći u poređenju sa sadržajem ugljenih hidrata koji je utvpđen u uzorcima osušenim na višim temperaturama sušenja. Na nižim temperaturama njihov sadržaj je bio veći nego kod viših temperatura sušenja. Značajni gubici vitamina C određeni su u svim sistemima sušenja. Vrednost likopena u svim eksperimentalnim uslovima sušenja pokazuje tendenciju blagog smanjenja. Poredeći sadržaj u suvim i svežim plodovima paradajza, gubitak je bio od 4,94% do 19,98%, ali ne na značajnom nivou.

AB  - Bacterial spot of pepper and tomato caused by Xanthomonas species, is one of the widespread and economically most important diseases of pepper and tomato. Due to the lack of resistant pepper and tomato genotypes, the emergence of new races of bacteria, and strains resistant to copper compounds, questionable seed quality and limited control practices, thesebacteria are limiting pepper production in Serbia. On tomato plants, under favourable weather conditions for disease development, these bacteria can cause major damage reflected in overall yield as well as in fruit quality. The protection of pepper and tomato, based on chemical methods such as use of copper-based compounds in combination with ethylene-bis-dithiocarbamates, do not provide a satisfactory disease control. Use of antibiotics in plant protection is not permitted in the EU as well as in Serbia. However, results of many authors show that satisfactory control of bacterial spot can be achieved by integrating positive effect of chemical treatments (copper compounds, systemic resistance activators) and various biological methods (antagonists, bacteriophages). However, nature of biological agents, as well as the specific mechanism of action of the systemic resistance activators, require careful optimization of the time and number of treatments in order to achieve maximum efficiency.

AB  - Bacterial spot of pepper and tomato regularly causes losses in production in Serbia. According to the new systematization, four Xanthomonas species have been reported as causal agents of leaf spots of pepper and tomato: X. euvesicatoria, X. vesicatoria, X. perforans and X. gardneri. Due to wide distribution and great damage at the global level, X. euvesicatoria is considered one of the most significant parasitic bacteria of pepper. Causal agent of the bacterial spot on tomato in Serbia is X. vesicatoria. Occurrence of of both species is observed every year under Serbian agroecological conditions, mainly due to the cultivation of susceptible assortment and conditions which are suitable for disease development. The disease is seed transmitted and it can cause defoliation and crop degradation if conditions suitable for its development occur. Bacterial spot of pepper and tomato cannot be combatted easily and application of several cultivation practices including conventional or microbial preparations - biopesticides is therefore required. The existence of natural antagonists (bacteriophage) isolated from soil has been confirmed, which could be used for biological control of pepper bacterial spot. In the absence of effective preventive measures, the solution should be sought within an integrated approach - the synthesis of knowledge about the biology and epidemiology of the pathogen, crop production technology, as well as bactericidal effect of some natural agents.

AB  - Bacterial diseases are very common in tomato and pepper crops, especially under favourable weather conditions. One of the economically most important pathogens that affect tomato production worldwide is Ralstonia solanacearum, causal agent of bacterial wilt of tomato. The pathogen survives in soil and water. It colonizes xylem, clogs the vascular tissue preventing water movement throughout the stem, causing colapse of the infected plants. In addition, wilting of tomato and pepper can be caused by Candidatus Phytoplasma solani (Stolbur Phytoplasma). Main sources of infection with this pathogen are wild plants from where it is further transmitted by feeding of leafhopper vectors. The aim of this paper is to point to distribution and economic importance of those diseases, as well as characteristics of the pathogens. Information about symptoms and epidemiology of the disease are important for an accurate disease diagnosis and pathogen identification, which contributes to the timely and successful protection strategy.

AB  - During the season 2016, the biological efficacy of contact fungicides in apple protection from the apple scab, caused by fungus Venturia inaequalis, was performed. The experiments were conducted in an experimental orchard at the location of OŠD Radmilovac (cv Idared) and commercial orchard on the location of Krćevac (Topola) (cv Mucu). The trials were performed as a randomized block system in four repetitions (EPPO, 2012). Fungicide treatments were performed using knap sprayer type Solo 423, with 1000 l ha-1 of suspension consumption. A total of seven treatment, starting from the growth stages of ''mouse ear'' (BBCH 54), were done.Favorable agro-meteorological conditions have resulted in the significant disease incidence in control (untreated) plots. At the site of the OŠD Radmilovac the intensity of disease determined in control plots was 28.4% on the leaves, and 7.3% on fruits, while on the locality of Krćevac, diseases occurrence on the leaves and fruits was 91.5% and 7.9%, respectively. Application of multi-site fungicides resulted in good efficacy of mancozeb (87.4 to 100%), dithianon (83.1 to 100%), metiram (86.6 to 95.3%) and captan (89.8 to 100%), respectively.

AB  - During the 2016 growing season, biological efficacy of fungicides mixture propamocarb hydrochloride + chlorothalonil, metalaxyl-M + mancozeb and metalksil-M + chlorothalonil in the control of downy mildew in pea crop (Peronospora viciae), was investigated. The experiments were conducted in the localities of Sakule and Glogonj. The experiments were carried out as randomized block system in four replications EPPO (EPPO, 1997). Two fugicide applications were conducted , one at the beginning of flowering (BBCH 61) (1st treatment), and second at the stage when 10% of pods reached typical size (BBCH 71) (2nd treatment). Favorable conditions resulted in significant disease intensity on untreated plots, which amounted from 19.9 to 24.8% in the first, and from 32.3 to 44.5% in the second assessment. Fungicide mixture propamocarb-hydrochloride + chlorothalonil exhibited efficacy ranging from 92.7-93.9% at the first and from 85.5 to 91.9% at the second assessment. Fungicide metalaxyl-M + mancozeb, reached the efficacy of 93.1-95.4% at the first, and 86.3-93.2% at the second assessment, while the highest efficacy was achieved by a combination metalaxyl-M + chlorothalonil, which ranged from 86.9 to 100% at the first, and from 86.9 to 95.3% at the second assessment.

The experiments were conducted in the localities of Sakule and Glogonj. The experiments were carried out as randomized block system in four replications EPPO (EPPO, 1997). Two fugicide applications were conducted , one at the beginning of flowering (BBCH 61) (1st treatment), and second at the stage when 10% of pods reached typical size (BBCH 71) (2nd treatment). Favorable conditions resulted in significant disease intensity on untreated plots, which amounted from 19.9 to 24.8% in the first, and from 32.3 to 44.5% in the second assessment. Fungicide mixture propamocarb-hydrochloride + chlorothalonil exhibited efficacy ranging from 92.7-93.9% at the first and from 85.5 to 91.9% at the second assessment. Fungicide metalaxyl-M + mancozeb, reached the efficacy of 93.1-95.4% at the first, and 86.3-93.2% at the second assessment, while the highest efficacy was achieved by a combination metalaxyl-M + chlorothalonil, which ranged from 86.9 to 100% at the first, and from 86.9 to 95.3% at the second assessment., U toku 2016. godine, vršena su ispitivanja biološke efikasnosti fungicida na bazi kombinacije propamokarb-hidrohlorid + hlorotalonil, metalaksil-M + mankozeb i metalksil-M + hlorotalonil u suzbijanju prouzrokovača plamenjače (Peronospora viciae) u usevu konzumnog graška.

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  - U leto 2014. godine, proizvođači lubenice iz sremskog okruga uočili su pojavu simptoma u vidu pega vodenastog izgleda i nepravilnog oblika na zrelim plodovima lubenice, koji su ukazivali na oboljenje bakteriozne prirode. Izolacijom i identifikacijom patogena, utvrđeno je prisustvo bakterije Acidovorax citrulli, prouzrokovača bakteriozne mrljavosti plodova lubenice. Ova vrsta je u skorije vreme dosta dobila na značaju, posebno zbog gubitaka u proizvodnji koji su u pojedinim oblastima Sjedinjenih Američkih Država (SAD) dostizali i 90% od ukupnog prinosa. U Srbiji A. citrulli ima karantinski status i nalazi se na A1 listi Evropske i mediteranske organizacije za zaštitu bilja (EPPO).

AB  - In 2012, the biological effi cacy of the fungicide mixture pyraclostrobin + boscalid (Signum®, BASF ) in the control of two economically most important disease of lettuce, gray mold (B. cinerea ) and downy mildew (B. lactucae ), was tested. The experiments were conducted at the location of Belgrade (Ledine, Iceberg, salat center), and Smederevska Palanka (Experimental fi eld of the Institute of Vegetable Crops), by type of randomized block design with four replications (EPPO, 1997). Fungicide application was performed by a sprayer SOLO 423 with consumption of 400 l of water ha-1. A fungicide Signum®, (a.i. pyraclostrobin + boscalid) was applied in a dosage of 1.5 kg ha-1 and was carried out a total of four treatments of the growth stages starting when the plants had developed three leaves (BBCH 13). As the standard products at both locations the fungicide Sumilex SC 50 (a. i. procymidone), in the case of B. cinerea, and Ridomil MZ (a.i. metalaxyl + mancozeb), in the case of for downy mildew, were used. After manifesting clear distinguish between treated and untreated (control) plots, assessment of disease severity (60 plants per plot) and efficiency of fungicides were calculated. The fungicide mixture pyraclostrobin + boscalid, tested in this study, showed a high efficacy against downy mildew of lettuce, which amounted to 93.6 % (Location: Belgrade - Ledine) and 97.4 % (site: Smederevska Palanka) respectively. The effi ciency of the tested fungicide combination of suppression of gray mold was 92.5 % (location: Belgrade - Ledine) and 93.5 % (site: Smederevska Palanka), respectively.

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. Due to lack of resistant cultivars and effective means of protection, researchers have searched for alternative solutions that would provide effective control of this disease. Only integration of different control methods can enable positive effect and achieve an adequate crop protection. Biological methods (use of bacteriophages) and some recent alternative treatments (Systemic Acquired Resistance inducers), have provided the possibility of developing an effective strategy for X. euvesicatoria control.

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.

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.

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.

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., 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.",
