AB  - Korovski suncokret, Helianthus annuus L., je ekonomski veoma značajna, invazivna vrsta koja
je rasprostranjena u mnogim delovima sveta, posebno u oblastima gde se intezivno gaje tolerantni
hibridi suncokreta na ALS ihnibitore. Otkriće i razvoj nove tehnologije gajenja suncokreta
povećalo je rizik od nastanka rezistentnih biotipova usled velikog selekciong pritiska i spontane
hibridizacije (transfer gena odgovornih za tolerantnost iz useva u divlje srodnike).
U radu je ispitivana reakcija dve populacije korovskog suncokreta (HELAN 1 i HELAN 2) na
imazamoks i nikosulfuron u biotestu sprovedenom u uslovima staklenika. Ogled je obuhvatao pet
tretmana sa različitim količina primene imazamoksa (12, 24, 48, 96 i 192 g ha-1) i nikosulfurona
(10, 20, 40, 80 i 160 g ha-1) koji su primenjeni kada su biljke bile u fazi 2-3 para razvijenih
listova. Pored vizuelne ocene oštećenja biljaka koja je izvedena 7, 14, 21 i 28 dana nakon primene
herbicida, mereni su i sledeći parametri: sveža i suva masa. Dobijeni rezultati ukazuju na promene
u osetljivosti ispitivanih populacija korovskog suncokreta na ALS inhibitore. Manja osetljivost
populacije HELAN 1 na imazamoks i HELAN 2 na nikosulfuron sugeriše na mogući razvoj
rezistentnosti kod populacija korovskog suncokreta na području Surčina.
AB  - Weedy sunflower, Helianthus annuus L. is an economically very important, invasive species
widely distributed in many regions of the world, especially in the areas where sunflower
hybrids tolerant to some ALS-inhibiting herbicides are intensively cultivated. The discovery
and development of a new technology in cultivated sunflower increased the emergence of
resistant biotypes due to high selection pressure and spontaneous hybridisation (transfer of
genes responsible for tolerance from crop to wild species).
This study examined the responses of two populations of weedy sunflower (HELAN 1
and HELAN 2) to nicosulfuron and imazamox in bioassay under greenhouse conditions. The experiment included five treatments with different application rates of imazamox (12, 24, 48, 96
and 192 g ha-1) and nicosulfuron (10, 20, 40, 80 and 160 g ha-1) that were applied over plants at
their growth stage of 2-3 pairs of developed leaves. In addition to the visual assessment of plant
damage, which was performed 7, 14, 21 and 28 days after the herbicide application, the following
parameters were also measured: fresh and dry weight. The obtained results indicate changes in the sensitivity of the examined weedy sunflower populations to ALS inhibitors. Reduced sensitivity
of the HELAN 1 to imazamox and HELAN 2 to nicosulfuron suggests a possible development of
resistant populations of weedy sunflower in the Surčin area.
