Herbicid hatékonyság vizsgálat őszi búzában, Viola arvensis, Apera spica-venti és árvakelésű Brassica napus fajokkal szemben

Abstract

The effective plant protection is decisive element of economical growing plants. The most important is the integrated plant protection, that is planned according to current problems. We can track continuous transformation of weedage flora with “Arable weeds of Hungary - Fifth National Weed Survey (2007-2008)”. In circle of wheat growers, actually Apera spica-venti causes significant crop loss. Viola arvensis is the other advancing weedage that causes crop loss. In practice, usually autumn wheat follows autumn rape (and vice versa), so we analysed imidazoline tolerant volunteer rape plants. We want to help growers realise to effective weedage control with results of mentioned above weedages against of defense experiment. Our investigations not only present efficiency of agents and combinations, but also when worth to do chemical treatment, that is compare autumn postemergence to sping postemergence chemical treatment. We want to draw attention early advantages of autumn postemergence chemical treatment and prefer autumn treatment to spring treatment.
