Changes in weed community composition in a long-term trial with different crop rotations and herbicide treatments

Popis výsledku v původním jazyce

The impact of herbicide application on weed community changes was studied in a longterm field experiment conducted since 1972 at two sites in the Czech Republic, area Pernolec and Hněvčeves. The ongoing trial comprises multicrop and simple crop rotations with 50 and 75% cereals, respectively. Three herbicide treatments were used 1 untreated, (2) synthetic auxins and (3) targeted herbicide combinations, including especially sulfonylureas, triazines, ureas and synthetic auxins. Weed species composition and weed density were assessed at the trial beginning, during the trial and in the present (from 2013 to 2016). Changes in weed flora composition were found out. In Hněvčeves, abundance of some species such as Galium aparine, Stellaria media, and Vicia spp. increased on untreated plots, the abundance of Apera spica-venti, Fumaria officinalis, and Tripleurospermum inodorum increased on treated plots. In Pernolec, some species receded in all variants, e.g. Myosotis arvensis, Raphanus raphanistrum, and S
