AB  - Soft rot symptoms were observed on broccoli plants in several commercial fields in the western part of Serbia. Six strains of bacteria were isolated from diseased tissues and identified as Pectobacterium carotovorum subsp. carotovorum using conventional bacteriological and molecular methods. All strains were non-fluorescent, gram-negative, facultative anaerobes, oxidase-negative and catalase-positive, causing soft rot on potato and carrot slices and did not induce hypersensitive reaction on tobacco leaves. They grew in 5% NaCl and at 37C, did not produce acid from α-methyl glucoside, sorbitol and maltose, nor reducing substances from sucrose, but utilized lactose and trehalose, and did not produce indole or lecithinase. The investigated strains showed characteristic growth on Logan's medium and did not produce blue pigmented indigoidine on GYCA medium nor 'fried egg' colonies on PDA. The identity of strains was confirmed by ITS-PCR and ITS-RFLP analyses and by sequence analysis of the 16S rRNA gene. In a pathogenicity assay, all strains caused tissue discoloration and soft rot development on inoculated broccoli head tissue fragments.
AB  - Simptomi vlažne truleži brokolija uočeni su u nekoliko komercijalnih zasada u zapadnoj Srbiji. Sojevi bakterija izolovani su iz obolelog biljnog tkiva i identifikovani kao Pectobacterium carotovorum subsp. carotovorum korišćenjem konvencionalnih bakterioloških i novijih molekularnih metoda. Svi proučavani sojevi bili su nefluorescentni, Gram-negativni, fakultativno-anaerobni, oksidaza i lecitinaza negativni, katalaza pozitivni, prouzrokujući vlažnu trulež cvetnih drški brokolija, kriški krompira i kriški mrkve, ali nisu indukovali hipersenzitivnu reakciju duvana. Svi sojevi razvijaju se pri 37C i u prisustvu 5% NaCl, ne proizvode kiselinu iz α-metil glukozida, sorbitola i maloze, niti redukujuće supstance iz saharoze, ali razlažu laktozu i trehalozu, i ne stvaraju indol. Proučavani sojevi ispoljili su karakterističan razvoj na Loganovoj diferencijalnoj podlozi, i nisu proizvodili plavi pigment na GYCA podlozi niti 'fried egg' kolonije na PDA podlozi. Identifikacija sojeva potvrđena je korišćenjem ITS-PCR i ITS-RFLP, kao i analizom sekvenci 16S rRNA gena. Prilikom izvođenja testa patogenosti, svi sojevi prouzrokovali su obezbojavanje tkiva i vlažnu trulež cvetnih drški brokolija.

AB  - The influence of shading on the incidence and development of P.leucotricha was examined at the locality of Belgrade, during 2008 and 2009. Investigation was carried out on two-year old apple nursery trees, cultivar Idared, sensitive to causal agent of apple powdery mildew. The experiment included three variants, two with different conditions of reduced light (24h and 48h shading, with 24h in the natural photoperiod) and the third variant, which included the cultivation of plants in natural photoperiod, without shading. Reduced light conditions were achieved by growing the plants under wooden experimental boxes. The boxes provided minimum differences in air temperature and RH values, inside and outside them. Inoculum was provided from two trees that were close to the experimental boxes, and the infection was carried out by direct application of conidia from infected young shoots and naturally, during growing period. Four assessments were made, three during shading period and one after removal of the experimental boxes. In both. years of investigation, the highest intensity of infection was manifested in the first variant (48h shading, 24h natural photoperiod), (14.0 - 100%), slightly lower in the second (24h shading, 24h natural photoperiod), (12.7 - 93.5%) and the lowest in variant of normal photoperiod, (0.1 - 16.6%). In shading variants, intensity of infection was rapidly increasing from the first to the third assessment, while in the fourth assessment, after the removal of boxes, it significantly decreased. The results of these studies indicate that light intensity significantly affects the appearance and development of P. leucotricha, and that apple powdery mildew develops intensively in the shade environmental conditions.

AB  - Peach rusty spot has regularly occurred in Serbia in recent years, causing significant economic losses in the production of late maturing cultivars (Summerset, Suncrest, Fayette and O'Henry). Concerns regarding the etiology of this disease have been solved using molecular identification and cross-pathogenicity tests, which have proved that peach rusty spot is caused by Podosphaera leucotricha. The usual recommended strategy for its control, by multiple treatments starting from petal fall phenophase, has not proved satisfactory in agro-ecological conditions in Serbia. After testing the fungicide efficacy, a three-year study was carried out to determine the precise treatment terms and make the control of P. leucotricha more efficient. The investigation was conducted in the conditions of natural infection in a Summerset cultivar orchard at the locality of Bela Crkva, during the period 2006-2008. Nine different variants of both single and mixed treatments were tested, covering six defined peach growth phenophases - from green top, until the phenophase of second fruit falling. In the conditions of high levels of natural infection in the control plots, in all three investigation years the most efficient was the variant in which kresoxim-methyl was applied three times: in green top, pink bud and full bloom phenophases (91.69 - 91.92%), followed by the variant of treatments in the phenophases of rose bud, full bloom and petal fall (86.3-87.87%) and the variant of two treatments, performed in the phenophases of pink bud and full bloom (79.3-83.09%). The other tested variants showed significantly lower efficiency. The results obtained could significantly contribute to better peach fruit production, without losses caused by peach rusty spot which is commercially very important disease in Serbia.
AB  - Rđasta mrežavost plodova breskve poslednjih godina u Srbiji redovno se javlja i u proizvodnji poznih sorti (Summerset, Suncrest, Fayette i O'Henry) nanoseći značajne ekonomske gubitke. Nedoumice u pogledu etiologije ove bolesti razrešene su na osnovu molekularne identifikacije i unakrsnih testova patogenosti čime je dokazano da rđastu mrežavost breskve izaziva Podosphaera leucotricha. Strategija kontrole P. leucotricha primenjena u svetu, po kojoj suzbijanje treba sprovoditi u višekratnim tretmanima od fenofaze precvetavanja, nije dala zadovoljavajuće rezultate u agroekološkim uslovima Srbije. Nakon izvršenih ispitivanja efikasnosti fungicida, obavljeno je trogodišnje istraživanje u cilju određivanja preciznih rokova tretiranja breskve radi uspostavljanja efikasne kontrole P. leucotricha. Ispitivanje je obavljeno u periodu od 2006. do 2008. godine, u zasadu breskve sorte Summerset, u uslovima prirodne zaraze na lokalitetu Bela Crkva. Testirano je devet različitih varijanti, koje su se sastojale iz kombinovanih i pojedinačnih tretiranja, tako da je pokriven period od šest definisanih fenofaza razvoja breskve, počevši od fenofaze zeleni vrh do fenofaze drugo opadanje plodova. U uslovima visokog nivoa prirodne zaraze u kontrolnim parcelama, najvišu efikasnost u sve tri godine ispitivanja ispoljila je varijanta u kojoj je kresoksim- metil primenjivan tri puta, u fenofazi zeleni vrh, roze pupoljak i cvetanje (91,69-91,92%), odmah zatim varijanta u kojoj su izvođeni tretmani u fenofazi roze pupoljak, cvetanje i precvetavanje (86,3-87,87%) i varijanta u okviru koje su bila vršena dva tretmana u fenofazi roze pupoljak i cvetanje (79,3-83,09%). Ostale varijante u ogledu ispoljile su znatno nižu efikasnost. Dobijeni rezultati značajno doprinose poboljšanom načinu proizvodnje breskve bez gubitaka izazvanih rđastom mrežavosti ploda, ekonomski sve značajnijeg oboljenja u Srbiji.

AB  - Peach rusty spot, an economically important disease of peach (Prunus persica var. persica), appears as necrotic spots on fruit. The etiology of the disease is still not well understood, although it has long been suspected that the causal agent is the apple powdery mildew pathogen, Podosphaera leucotricha. This work confirmed this hypothesis based on cross-inoculation experiments and analysis of rDNA internal transcribed spacer sequences polymerase chain reaction amplified from rusty spot and peach powdery mildew lesions. Cross-inoculations of apple and peach leaves with P leucotricha and P. pannosa, the causal agent of peach powdery mildew, showed that (i) young peach fruit, up to 5 cm in diameter, developed symptoms typical of rusty spot following inoculation with P. leucotricha; (ii) leaves of 'Jonagold' apple seedlings developed powdery mildew infections when inoculated by touching young rusty spot lesions to their surfaces; (iii) P leucotricha sporulated on young peach fruit up to 5 cm in diameter; and (iv) peach leaves and young shoots were not susceptible to P leucotricha, whereas P. pannosa infected all the green parts of peach. A field experiment revealed that there was only a 2- to 3-week period of time during early peach fruit development when the epidermis was susceptible to P leucotricha. An outcome of this study is that now a clear distinction can be made between the symptoms caused by P pannosa and P leucotricha on peach.

AB  - Rusty Spot has long been known as a harmful peach disease in many parts of the world. During the past several years, rusty spot infection of the late-maturing peach cultivars (Summerset, Suncrest, Fayette and O'Henry) caused significant yield losses in Serbia. Although the etiology of the disease is still unknown, there are numerous studies attempting to set a strategy for its control and recommend appropriate chemical and other peach protection methods. However, because of specific environmental conditions in Serbia, recommended protection method using repeated fungicide treatments, starting from petal fall, did not prove to be efficient and the rate of infection in some susceptible peach cultivars reached 100%. In 2003 and 2004 a field trial was conducted in order to test the efficacy of fungicides (a.i. kresoxim-methyl, flusilazole and sulfur) for the efficient control of Rusty Spot epidemics. The trial was carried out under conditions of natural infection on the peach cv. Summerset at the locality of Bela Crkva, Serbia. In the untreated control plots, high disease incidence was recorded with the percentage of affected fruit surface ranging from 33.5% in the first, up to the 35.4% in the second year of the trail. Among fungicides included in the trial, kresoxim-methyl proved to be the most efficient (90.25% in the first and 91.12% in the second year of the trial), flusilazole exhibited lower efficacy (87.28% and 80.61%, respectively) while sulfur was the least efficient (82.33% and 80.30%, respectively). Determination of the most efficient fungicide for the peach rusty spot control in Serbia provides basic information for further investigations which will include optimization of treatment terms, as well as additional agro-technical control measures.
AB  - Rđasta mrežavost plodova breskve odavno je poznato i ekonomski značajno oboljenje u mnogim delovima sveta. U Srbiji tokom proteklih godina ovo oboljenje nanosi značajne štete na poznim sortama breskve (Summerset, Suncrest, Fayette i O'Henry). Mada etiologija bolesti nije poznata, brojna istraživanja u mnogim delovima sveta pokušavaju da uspostave strategiju za kontrolu i preporuče odgovarajuće hemijske i druge metode zaštite breskve. U agroekološkim uslovima Srbije strategija primenjena u svetu, da suzbijanje prouzrokovača rđaste mrežavosti treba sprovoditi u višekratnim tretmanima od fenofaze precvetavanja, nije dala zadovoljavajuće rezultate. U pojedinim godinama zaraza plodova osetljivih sorti breskve dostiže 100%. U periodu od 2003. do 2004. godine, ispitivana je efikasnost tri fungicida (kresoksim-metil, fluzilazol i elementarni sumpor) u cilju iznalaženja mogućnosti uspešnije zaštite breskve od prouzrokovača rđaste mrežavosti plodova. Ogled je izveden na breskvi, sorte Summerset, u uslovima prirodne zaraze na lokalitetu Bela Crkva. Intenzitet zaraze rđaste mrežavosti plodova na osnovu procenta zahvaćene površine plodova, u kontrolnim parcelama kretao se od 33,5% u prvoj do 35,4% u drugoj godini ispitivanja. Tokom obe godine ispitivanja kresoksim-metil ispoljio je najveću efikasnost (90,25% u prvoj, odnosno 91,12% u drugoj godini ispitivanja), nižu fluzilazol (87,28%, odnosno 87,61%) i najnižu elementarni sumpor (82,33%, odnosno 80,30%). Određivanje fungicida sa najefikasnijim delovanjem prema prouzrokovaču rđaste mrežavosti plodova breskve u Srbiji predstavlja preduslov za dalja ispitivanja koja će uključiti pre svega optimizaciju rokova fungicidnih tretmana kao i određivanje drugih agrotehničkih mera kontrole.
