THE WEED CONTROL STRATEGIES OF APERA SPICA-VENTI IN WHEAT CROPS PUBLISHEDCornelia Ciobanu
Cultivating wheat in monoculture and practicing a short rotation determine proliferation of some specific weeds like as Apera spica-venti like as gravity in floristic structure and like as quantitative and numeric too. The weeds dynamics in wheat monoculture crop and in two, three, four rotations show an increasing of total weeds inclusive of Apera spica-venti in monoculture and in short rotation (wheat - maize), where infestation degree is taken values by 72%, respective 65% after 23 years. Three and four year’s rotation contributes at decreasing of total infestation and of specific weeds too. Chemical control measures for Apera spica-venti are necessary in wheat monoculture and also in short rotation (wheat - maize) to, utilizing specific herbicides (Puma S, Attribut, Axial) associate with those for dicotyledonous (Rival Super Star, Peak) which will assure a 92 – 94% efficacy and very significant yield spores.
