Four species of the Helianthus genus have been found in the non-arable and arable communities in Vojvodina and Serbia, namely: H. annuus, H. tuberosum, H. decapetalus and H. scaberimus. Studies conducted hitherto have shown that Helianthus annuus has the highest frequently in all weed phytocoenoses examined so far. The spreading of H. decapetalus and H. scaberimus, introduced to Vojvodina from the neighboring Hungary and Romania, has still not assumed alarming proportions in quantitative terms, but a tendency has been observed of their further spreading. It is therefore necessary to monitor and study the trend of their expansion over the coming period.
