Mono and dicotyledonous weeds are the competitors of fruit species, in terms of growth, bearing and fruit quality. Therefore, in fruit growing, the aim is to keep the spectrum of weeds below the economic damage threshold (EDT). In this sense, different methods are used: biotechnical (mulching), mechanical (mowing), agrotechnical (black field worked, weeding between rows) or chemical (pre- or post-emergent herbicide use). The paper presents the results of research undertaken between 2019-2021 on the effectiveness of 6 post-emergent herbicides (4 total, based on glyphosate and 2 including other molecules - cycloxidim 100 g / l and oxifluorfen 240 g / l). The application of the products was carried out in an experimental module with the apple varieties 'Jonathan / M9' and 'Idared / M9', 5-7 years old, in variants and replications arranged randomly. Observations and determinations were performed according to the European Weed Research Society (EWRS) scale showed that, from the whole spectrum of weeds followed in the experimental device, the most difficult or difficult to control were the dicotyledonous weeds such as: Equisetum arvense (note 8-9), Cirsium arvense, Gallium aparine, Galinsoga parviflora, Malva neglecta, Matricaria chamomilla, Ranunculus repens, Rumex spp., Stelaria media (note 5). Among the monocotyledons difficult to control were: Agropyron repens, Lolium perene and Cynodon dactylon, requiring the application of herbicides twice vegetation season, or the integrated control of weeds.
