Field experiments were conducted
during two winter wheat
-
growing seasons to
evaluate the efficacy of some new POST herbicides and herbicide combinations for those
effective controls of weeds in winter wheat crops in the Republic of Macedonia. The weed
population consisted mainly of annua
l winter and spring and some perennial weeds. Weediness
comprised 116 and 208 plants m

region, and 93 and 114 plants

effectively reduced
dominant weeds density (

region in both years, as well as in the Probištip region in 2012

herbicides,
which provided control of
Lolium perenne
that was between 76 and 84%; control of

control of

was
no more than 83% and
no one

Wheat yields i

significant among years for the different POST herbicide
applications and ranged between 3,580
