Efficacy and phytotoxicity of post emergence herbicides in garlic | Učinkovitost in fitotoksičnost herbicidov uporabljenih po vzniku česna

English. The incidence of weeds in the garlic crop interferes with the quality and quantity of the harvest. This study aimed to evaluate the efficiency of herbicides in different combinations of sequential applications during the cultivation of garlic. The experiment was carried out in a randomized block design, with ten treatments and four replications. The treatments consisted of sequential applications of the herbicides pendimethalin, pyroxasulfone/flumioxazin, ioxynil, and pendimethalin. The doses of Herbadox® (pendimethalin) were 4.0 l∙ha-1, Totril® (ioxynil) 1.5 l∙ha-1, and Kyojin® (pyroxasulfone/flumioxazin) 0.15 l∙ha-1. Treatments consisted of sequential applications of herbicide combinations. Applications were performed 7, 58, 97, and 128 days after planting. Phytotoxicity on the crop, efficacy in weed control, bulb classification, and productivity were evaluated. The results were submitted to ANOVA, and the means were compared by the Scott-Knott test. The sequential application of pyroxasulfone/flumioxazin at 7 days after planting (DAP), ioxynil at 58 DAP, pendimethalin at 97 DAP, and pyroxasulfone/flumioxazin at 128 DAP (T7) stood out (96–100 % control of weeds, average productivity of 11.42 t·ha-1), which presented the best results relative to phytotoxicity, weed control, bulb classification, and crop productivity.

Slovenian. Pojavnost plevelov v nasadih česna vpliva na količino in kakovost pridelka. V raziskavi je bila ovrednotena učinkovitost herbicidov v različnih kombinacijah v zaporednih nanosih med gojenjem česna. Poskus je bil zasnovan v naključni bločni obliki, z desetimi obravnavanji in štirimi ponovitvami. Obravnavanja so obsegala zaporedno uporabo herbicidov kot so pendimetalin, piroksasulfon/flumioksazin, ioksinilin pendimetalin. Odmerki Herbadox-a® (pendimetalin) so bili 4,0 l∙ha-1, Totril-a® (ioksinil) 1,5 l∙ha-1in Kyojin-a® (piroksasulfon/flumioksazin) 0,15 l∙ha-1. Obravnavanja so bila izvedena v zaporednih kombinacijah herbicidov. in sicer 7, 58, 97 in 128 dni po sadnji. Ovrednotene so bile fitotoksičnost za posevek, učinkovitost zatiranja plevelov, klasifiklacija čebulic in produktivnost. Rezultati so bili obdelani z ANOVA, poprečja so bila primerjana s Scott-Knottovim testom. Zaporedna uporaba piroksasulfona/flumioksazina 7 dni po sadnji (DAP), ioksinila 58 DAP, pendimetalina 97 DAP in piroksasulfona/flumioksazina 128 DAP (T7) je izstopala (96–100 % nadzor plevelov, poprečna produktivnost 11,42 t·ha-1), kar je predstavljalo najboljše rezultate glede na fitotoksičnost, nadzor plevelov, klasifikacijo čebulic in produktivnost česna.
