The efficacy of fluroxypyr in controlling annual and perennial broad-leaved weed species in wheat, spring barley, maize and orchards was tested. Trials were set up in a random block design in two localities per crop in 2007. Fluroxypyr was applied at recommended rates for each cultivated species. Weeds were in a stage between 3 leaves and emergence of flag leaf in wheat and barley crops, and in a 3-6 leaves stage in maize, while those on orchards were intensively growing. The data collected show that fluroxypyr can be used for successful control of many broad-leaved weeds: Ambrosia artemisiifolia, Capsula bursa-pastoris, Chenopodium album, Chenopodium hybridum, Consolida orientalis, Consolida regalis, Convolvulus arvense, Erigeron canadensis, Galium aparine, Geranium dissectum, Lactuca serriola, Lepidium draba, Pastinaca sativa, Polygonium convolvulus, Polygonium lapathifolium, Rubus caesius, Sinapis arvensis, Sonchus arvensis, Stellaria media, Stenactis annua, Taraxacum officinae, Veronica persica, and Xanthium strumarium. It also provides satisfactory protection against Linaria vulgaris, Mentha arvensis and Vicia sativa, but its efficacy against Cirsium arvense and Papaver rhoeas was found insufficient.
