摘要：Ambrosia artemisiifolia L.(Family Asteraceae) has been observed along the banks of the river Danube near Petrovaradin,Sremski Karlovci and Novi Sad,as well as near Bogojevo,Odzaci,Bač,and Bačka Palanka.This invasive,weedy-ruderal and quarantine species spreads northwards to the environs of Kula,Begeč and Futog in the region of Bačka,as well as in central and southern Banat.Over the period 2006-2007,studies of ragweed distribution and its mapping were performed on over 90 ha of non-agricultural land,i.e.on over 100 locations in 21 city zones of Novi Sad.In 2006,ragweed was found on about 200 locations of the 400 ha of non-agricultural land fully checked in the suburban areas of Novi Sad.In the territory of Zrenjanin,a systematic inspection of ragweed detected it on a total of 93090 m2 in the past two years.In 2006 and 2007,mapping of this invasive weed species was performed using a special software Ambrosia Spot Marker developed specially for this purpose.The abundance and distribution of ragweed were recorded in the software according to the Brauen-Blanquet method.Based upon these data,the lowest toxicity chemical control measures for this invasive weed species were determined in combination with mechanical ones.
其他摘要：Ambrosia artemisiifolia L.(familija Asteraceae) uvrđena je na obalama Dunava,blizu Petrovaradina,Sremskih Karlovaca i Novog Sada,kao i u blizini Bogojeva,Odžaka,Bača,Bačke Palanke.Ova invazivna,korovsko-ruderalna i karantinska vrsta (A2 lista) se raširila severno blizu Kule,Begeča i Futoga,u bačkom regionu,kao i u centralnom i južnom Banatu.Ispitivanja rasprostranjenosti,kao i mapiranja,ambrozije,vršena su tokom 2006-2007.godine,na teritoriji opštine Novi Sad,na preko 90 ha nepoljoprivrednih površina,preko 100 lokacija u 21 gradskoj zoni.Tokom 2006.godine od ukupno pregledanih oko 400 ha nepoljoprivednih površina u prigradskom području grada Novog Sada,ambrozija je utvrđena na oko 200 lokacija.U protekle dve godine,sistematskim praćenjem širenja ambrozije utvrđena je na teritoriji opštine Zrenjanin na ukupnoj površini od 93090 m2.Mapiranje rasprostranjenosti ove invazivne korovske vrste urađeno je u posebnom softverskom programu Ambrosia Spot Marker,koji je napravljen upravo za ovu namenu.Softverom je prikazana brojnost i pokrovnost ambrozije,prema metodi Brauen-Blanquet.
