Autumn Application of Synthetic Auxin Herbicide for Weed Control in Cereals in Poland and Germany

The biological efficacy of herbicides MCPA+tribenuron-methyl (code name: MT-565 SG) and diflufenican+chlorotoluron (Legato Pro 425 SC) was estimated in eighteen field experiments on winter cereals Poland Germany to control broadleaf weeds. Postemergence application tribenuron-methyl combination with MCPA, applied at the 3-leaf stage 3 tillers detectable autumn cereals, resulted majority weed species occurring being effectively eliminated 1.0 kg∙ha–1. It also provided an acceptable (82.4–94.1%) comparable level commonly weeds Brassica napus, Capsella bursa-pastoris, Centaurea cyanus, Lamium purpureum, Tripleurospermum inodorum, Stellaria media, Thlaspi arvense. A satisfactory 66.3 88.3% confirmed for Veronica persica, Viola arvensis, Galium aparine. According these results, formulation combined MCPA can be recommended as alternative available herbicides.
