The subject of this paper is to indicate the permanence degree changes of Abutilon
theophrasti Medic, appeared as a consequence of irregular usage of herbicides,
environmental changes, as well as the applying different modern farming methods. The
region of Mačva coversthe area of approx. 80000 ha, with different types of soil, and
with corn as the most represented field crops. The area of Western Srem is about 762
km2, it has more types of soil which enables an intensive agricultural production, but
mostly sown is corn. The total amount of arable land in Semberija is approx. 54000 ha,
and the most represented agricultural cultures are granaries ( wheat, corn, barley ).
Although the great estattention, in the sense of modern farming methods, is paid to the
field crops grown on the testing territories, corn sowing in monoculture, excessive usage
of herbicides, reduced primary processing, as well as global environmental changes, led
to the extremely frequent appearance of Abutilon theophrasti , that was not present in
such amount before. Velvetleaf is anannual plant, terophit (T4), belonging to late spring
weeds. On the basis of the results obtained from this paper, it can be concluded that
fertile and rich land of Mačva is the most suitable for Velvetleaf being a nitrophilous
plant (N4). Bad climate conditions, during the period of sowing field crops in the past
few years, contributed to the late sowing, as well as using some modern farming
methods and the usage of herbicides. The results obtained from the territory of Western
Srem and Semberija, being rather less than those from Mačva, indicate the importance
of modern farming methods and crop rotation in order to suppress this invasive weed
type. Speaking of the already mentioned territories and because of a more suitable
climate, they are done timely and completely. Fitocenološki snimci su pravljeni 2008. godine na području Mačve, Srema i
Semberije, u okopavinama na većem broju lokaliteta. Nepravilna i neracionalna
upotreba herbicida je znatno doprinela izmeni kvantitativnog i kvalitativnog sastava
korovskih zajednica na istraživanim područjima. Cilj ovog rada je da ukaže na promene
stepena stalnosti Abutilon theophrasti Medic. nastale kao posledica takve upotrebe
herbicida, klimatskih promena, kao i primene različitog stepena agrotehnike.
