Efficacy and phytotoxicity of post emergence herbicides in garlic

Suliani, Dionatan (author), Silvestre, Wendel Paulo (author), Dal Magro, Taísa (author)

The incidence of weeds in the garlic crop inter-feres with the quality and quantity of the harvest. This study aimed to evaluate the efficiency of herbicides in different com-binations 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 treat-ments consisted of sequential applications of the herbicides pendimethalin, pyroxasulfone/flumioxazin, ioxynil, and pen-dimethalin. 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 ap-plications of herbicide combinations. Applications were per-formed 7, 58, 97, and 128 days after planting. Phytotoxicity on the crop, efficacy in weed control, bulb classification, and pro-ductivity were evaluated. The results were submitted to ANO-VA, 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

• Title: Učinkovitost in fitotoksičnost herbicidov uporabljenih po vzniku česna

Abstract

Pojavnost plevelov v nasadih česna vpliva na količino in kakovost pridelka. V raziskavi je bila ovrednotena učinkovitost herbicidov v različnih kombinacijah v zapored-nih nanosih med gojenjem česna. Poskus je bil zasnovan v naključni bločni obliki, z desetimi obravnavanji in štirimi po-novitvami. Obravnavanja so obsegala zaporedno uporabo her-bicidov kot so pendimetalin, piroksasulfon/flumioksazin, iok-sinilin pendimetalin. Odmerki Herbadox-a® (pendimetalin) so bili 4,0 l∙ha-1, Totril-a® (ioksinil) 1,5 l∙ha-1in Kyojin-a® (piroksa-sulfon/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 pos-evek, učinkovitost zatiranja plevelov, klasifiklacija čebulic in produktivnost. Rezultati so bili obdelani z ANOVA, poprečja so bila primerjana s Scott-Knottovim testom. Zaporedna up-oraba 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 predstavl-jalo najboljše rezultate glede na fitotoksičnost, nadzor plevelov, klasifikacijo čebulic in produktivnost česna.
