Abstract:V letu 2015 smo v posevku koruze izvedli poljski poskus, v katerem smo analizirali učinkovitost herbicidov za zatiranje novih invazivnih vrst plevelov. Glavni namen je bil preveriti učinkovitost herbicida, ki vsebuje snovi teinkarbazon in formasulfuron (H1), katerega smo ga nanesli v različnih odmerkih. Drugi testirani herbicidi, ki smo jih uporabili kot primerjalni standard, so vsebovali naslednje aktivne snovi: mezotrion + terbutilazin + metolaklor (H2), mezotrion + nikosulfuron + dikamba (H3), izoksaflutol (H4), tembotrion (H5), tienkarbazon + izoksaflutol (H6) in foramsulfuron + jodosulfuron (H7). Herbicide smo nanesli v rastni fazi koruze BBCH 13‒14 ali BBCH 15. Glavne vrste plevelov, ki smo jih preučevali, so bile: Abutilon theophrasti, Amaranthus rudis, Ambrosia artemisiifolia, A. trifida, Bidens subalternans, Cyperus esculetus, Iva xanthiifolia, Panicum dichotomiflorum, Setaria faberi in Sorghum halepense. Pri uporabi H1 smo dosegli zelo visoke učinkovitosti zatiranja pri vseh plevelih (pri večini nad 95 %). Najbolj primeren čas za uporabo H1 je v fazi koruze BBCH 14 v odmerku 18 g/ha teienkarbazona + 60 g/ha foramsulfurona, ko imajo dikotiledonski pleveli prvi pravi list, enoletne trave dva prava lista in sirek tri liste.

Title:Herbicide Efficacy Testing for Control of New Invasive Weeds in Maize
Abstract:A field trial was carried out in 2015 to study the efficacy of herbicides for the control of several new invasive weeds in maize stand. The main study objective was to determine the efficacy of a herbicide based on a combination of tiencarbazone + foramsulfuron (H1), applied at different hectare rates. Other tested herbicides, which served as standards for comparison with H1, were based on: mesotrion + terbutilazine + metolachlor (H2), mesotrion + nicosulfuron + dicamba (H3), isoxaflutole (H4), tembotrione (H5), tiencarbazone + isoxaflutola (H6) and foramsulfuron + iodosulfuron (H7). Herbicides were applied at the BBCH 13-14 or at the BBCH 15 maze growth stage. The main studied weeds were: Abutilon theophrasti, Amaranthus rudis, Ambrosia artemisiifolia, A. trifida, Bidens subalternans, Cyperus esculetus, Iva xanthiifolia, Panicum dichotomiflorum, Setaria faberi and Sorghum halepense. H1 provided a very high level of control for all tested weeds (at most more than 95 %). The most suitable time for application is at the BBCH 14 at rate of 18 g/ha of teiencarbazone + 60 g/ha foramsulfuron when dicotyledonous weeds get their first true leaves, annual grasses the second trues leaves and sorghum their third leaves.
