AB  - It is essential that certified potatoes are free from known viruses which can negatively affect quality and yield. However, very little is known about the distribution and frequency of Potato virus S (PVS) in Serbia. Until 2014, PVS was present sporadically in the domestic seed potato production. The incidence of PVS was studied by a molecular method over 3 years (2014-2016) in four important potato-growing regions (Moravidd. Zlatiborski, Raski and Macvanski) and in different cultivars. The results showed that the incidence of PVS increased steadily over 3 years from 1.52 to 8.84%. The Moravicki region had the highest incidence (13.06%) and Desiree was the most susceptible cultivar with a mean PVS incidence of 8.2% followed by Marabel and Riviera. The highest significant statistical difference was between the cultivars and in the interaction between cultivars and regions. A detailed phylogenic analysis of the tested isolates contained that Serbian PVS belongs to PVSO. Of the 18 Serbian PVS isolates included in this study, eight were grouped into the PVSO cluster and formed a subgroup (O-I) with isolates from the USA, Syria, Korea and Chile. Ten Serbian isolates of PVS together with the isolates from Iran were clustered in a branch of subgroup O-VII. This study constitutes the fast report of PVS isolates in Serbia which are capable of infecting Chenopodium quinoa and inducing the symptoms of local chlorotic lesions.

AB  - The study was conducted to examine variability of green forage yield (GFY) and morphological traits (tiller length, internodes length, internodes-stem diameter, leaf width and length) in nine alfalfa varieties from USA and six varieties from Europe. The trials were carried out in Central Serbia during the second (2006-A1) and third year (2007-A2) of alfalfa exploitation. In unfavourable environmental conditions (A1), varieties from the USA had higher coefficient of variability (CV, %) in all cuttings (I CV= 16.93, II CV= 17.13, III CV=13.00, IV CV=21.29), as well as total yield variability (CV=14.33), compared to varieties from Europe (I CV=7.45, II CV=6.47, III CV= 10.65, IV CV= 19.51, for total yield CV=6.43). In the favourable agro-ecological conditions (A2) genetic potential of varieties was manifested, which caused similar yield variability. Variety origin (USA or Europe) had a low effect on variability of the morphological traits. The highest correlation (P  lt = 0.001) was achieved between yield and tiller length, regardless of variety origin.

AB  - C. apii is one of the most damaging plant pathogenic fungi of celery. During the 2012, samples of celery with typical symptoms of leaf blight were collected on the territory of Veliko Grdaište and their identification is performed using morphological and molecular methods. The pathogenicity test was conducted on healthy plants and all tested isolates caused typical symptoms after inoculation. Conidiophores arising from the stromata formed dense fascicles or single, straight to slightly curved, brown. Conidia are solitary, hyaline and septate (5-13 septa), cylindrical to obclavate, or straight to slightly curved, obtuse at the apex. Truncated and thickened at the base. Fragments of the expected length for the internal transcribed spacer (ITS1/ITS4), calmodulin (CAL-228F/CAL2Rd) and histone (CYLH3F/ CYLH3R) gene were amplified and the obtained sequences showed 100% identity with the C. apii sequences deposited in GenBank.

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.

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.

Ispitivanje je obavljeno u periodu od 2006. do 2008. godine, u zasadu breskve sorte Summerset, u uslovima prirodne zaraze na lokalitetu Bela Crkva.

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%).
