THE INFLUENCE OF SOME HERBICIDES ON WEED DEGREE DECREASING AND THE INFLUENCE ON MAIZE YIELD IN THE NORTH - WESTERN PART OF ROMANIA PUBLISHED

Cornelia Ciobanu, Gheorghe Ciobanu, Adrian Vuşcan
In the control technology, the appropriation of combined herbicides having fundamentally Atrazin will be replaced with herbicides having fundamentally Terbutilazin which have a similar efficiency in annual weeds (91 – 93%), but without any remanence for environmental and for next cultures. For annual and perennial weeds control the alternative control methods are based on utilization of some associate treatments (preemergents or ppi) (Metaclor, Acetoclor, Dimetenamid) with those post-emergent (Mesotrine,Prosulfuron, Primsulfuron/prosulfuron) as well as application of herbicides only post-emergent (Rimsulfuron/Dicamba, Mesotrine + Nicosulfuron). The exclusive post-emergent application follows after choosing the strategy depending on the weeds infestation.
