“…Na ruderalnim staništima Pančevačkog rita, u neposrednoj blizini oranica, prisustvo KS navode Stanković-Kalezić (2007) i Stanković-Kalezić i sar. ( 2007), a na osnovu visoke brojnosti, pokrovnosti i stepena stalnosti ima status edifikatora novoopisane ruderalne zajednice Matricario-Helianthetum annuae (Stanković-Kalezić, 2008). Osim toga, tokom druge godine istraživanja, u vreme sazrevanja pšenice na ovom lokalitetu evidentirane su velike oaze KS koje su se održale tokom cele sezone i to pre svega zbog loše obrade zemljišta, neadekvatnog setvenog sklopa useva i smanjene osetljivosti na primenjene herbicide (Slika 2c).…”

The Helianthus annuus L. species which appears as a weedy sunflower differs from the sunflower crop in height, pronounced branching, phenotypic variability, presence of anthocyan pigment, numerous small heads, relatively small and morphologically variable seeds (shape, color, motlling), dormancy and seed brittleness, etc. Weedy sunflover (WS) has been spreading for more than two decades on crop and non-cropland in the area with intensive sunflower crop production in Serbia, where it causes large yield losses in many crops (row crops and cereals). Bearing this in mind, as well as the fact that there have been confirmed cases of reduced herbicide efficacy on WS, the aim of this study was to determine the distribution and define the population size of WS in the whole territory of Serbia. During a three year period, in the region with intensive sunflower crop production (Banat, Bačka, Srem, Stig), the present WS populations were monitored and the quantitative and qualitative traits of their populations were assessed. A scale from 1-4 was used to estimate the number of plants in the population (1 - species cover up to 5% of the surveyed area, 2 - species cover 10-15% of the surveyed area, 3 - species cover 25-50% of the surveyed area, and 4 - species cover over 50% of the surveyed area). Over 200 populations of WS have been recorded in the whole territory of Serbia, and this is shown on a UTM map of 10x10 km scale. The largest WS populations (5 to 15 ha), with the highest number of plants (> 100,000) and average density (about 5 m-2 plants) were recorded in the site of Padinska Skela (in crop and non-croplands), Zbeg (predominantly on non-cropland) and Surčin-Galovica (predominantly in cropland). Based of the phenotypic diversity/discrimination traits, the population from Stari Žednik was the most similar to sunflower crop [with the central head and apical branching, the lowest number of heads compared with other WS populations (18.5 plants-1, while some populations had up to 59.4 heads plant-1) and the largest head size (8.1 cm in diameter)]. These results should be a guide for the farmers when planning crop planting, to undertake the best measures to control WS within the concept of antiresistance strategy, given the confirmed cases of reduced susceptibility of this weed to herbicides, as well as the obligation to eliminate it on non-cropland, as its main corridors of expansion are areas along roads and canals, field crop margines, lost cropland, etc.

“…The first significant findings on ruderal flora and vegetation in Serbia dates back to the early 20th century when Adamović (1909) described the different formations of ruderal and segetal plants in the central Balkans: at rubbish dumps, along roadsides and in abandoned fields. This type of vegetation was later the subject of research by numerous botanists (Slavnić, 1951;Šajinović, 1968;Jovanović, 1993Jovanović, , 1994Stanković-Kalezić, 2007, Stanković-Kalezić et al 2008Kojić et al, 2004;Perišić et al, 2004;Jovanović and Mitrović, 1998;Prodanović et al, 2008;Pajazitaj, 2009;Jarić, 2009). In addition to the extensive research into the flora and vegetation of major cities in the world (erhart, 2002;Sukopp, 2002;Brandes, 2004), a significant number of researchers have also dealt with the problems of the diversity of ruderal flora and vegetation along roadsides (Heindl and ulman, 1991;Wrobel, 2006), within large agrarian complexes (Prach, et al, 2001), and in the vicinity of large forest complexes (Akbar et al, 2003).…”

Floristic research investigating the presence and phytocoenological differentiation of ruderal vegetation, and how it is conditioned structurally and anthropogenically, was undertaken over a period of several years (2007-10) in the south Srem region. The ruderal flora of the research area comprised 249 plants categorized into 63 families, of which the most frequent were: Asteraceae (36), Poaceae (29), Fabaceae (18), Lamiaceae (15), Polygonaceae (15), Brassicaceae (11) and Rosaceae (11). Three ruderal communities are analyzed in this work: Asclepietum syriacae Kojić et al., 2004, as well as Chenopodio-Ambrosietum artemisiifoliae ass. nova and Amorpho-Typhaetum ass. nova, which are described for the first time. It was established that the level of moisture at the habitat, anthropogenic factors, and the immediate proximity to cultivated areas had the most pronounced effect on the differentiation of the researched vegetation
