Resumo: | There are few pre-emergent herbicides that are selective and registered for potato crop. Thus, this study aimed to evaluate the control of weeds with pre-emergent herbicides, as well as their effects on potato crop. The treatments consisted of a control, a hoed control (manual weed removal), metribuzin (240 g ha-1), linuron (450 g ha-1), diclosulan (25,2 g ha-1), imazetapir (700 g ha-1), prometryn (1000 g ha-1), clomazone + carfentrazone (300 + 7.5 g ha-1), clomazone + carfentrazone (600 + 15 g ha-1) and sulfentrazone (125 g ha-1). A randomized complete block design (RCB) was used with four replications. Largest stem, phytotoxicity, and weed control were measured at 10 and 30 days after stem emergence (DAE), which coincided with the periods before and after hilling, respectively. Soluble solids content, yield and tuber classification were determined after harvesting. The results were compared by a Tukey test (5% significance). The evaluated herbicides did not affect the number of stems per meter and length of the largest stem. Regarding weed control, clomazone + carfentrazone (600 + 15 g ha-1) controlled C. benghalensis (Behghal dayflower), E. heterophyla (milkweed) and R. raphanistrum (wild radish), better than the other herbicides, which provided little control over E. heterophyla and R. raphanistrum. The strongest symptoms of phytotoxicity were observed with metribuzin, diclosulan and imazethapyr, which were also associated with lower levels of soluble solids, total yield, and yield of "special" tubers. Therefore, these herbicides were considered less selective. Linuron and clomazone did not produce phytotoxicity, did not affect levels of soluble solids, and did not reduce total or "special" tuber yield, and were thus considered more selective for this potato cultivar. |

Assim, este estudo teve como objetivo avaliar o controle de plantas daninhas com herbicidas pré-emergente, bem como seus efeitos na cultura da batata. Os tratamentos foram testemunha, testemunha capinada, metribuzin (240 g ha-1), metribuzin (480 g ha-1), linuron (450 g ha-1), linuron (990 g ha-1), diclosulan (25,2 g ha-1), imazetapir (700 g ha-1), prometryn (1000 g ha-1), clomazone (360 g ha-1), clomazone + carfentrazone (300 + 7,5 g ha-1), clomazone + carfentrazone (600 + 15 g ha-1) e sulfentrazone (125 g ha-1). O delineamento experimental utilizado foi o de blocos casualizados (DBC), com quatro repetições totalizando 52 parcelas. Foram realizadas avaliações número e comprimento da maior haste, fitotoxicidade e controle de plantas daninhas aos 10 e 30 dias após emergência das hastes (DAE), que correspondem ao período antes e após da operação de amontoa, respectivamente. Após a colheita foram avaliados o teor de sólidos solúveis, produtividade e classificação. Os resultados obtidos foram comparados pelo teste de Tukey a 5% de significância A ocorrência de plantas daninhas proporcionou redução de produtividade. Os herbicidas avaliados não afetaram o número de hastes por metro e comprimento da maior haste. No controle de plantas daninhas, os herbicidase clomazone + carfentrazone (600 + 15 g ha-1) controlaram C. benghalensis, E. heterophyla e R. raphanistrum, se destacando frente aos demais, que apresentaram baixo controle das espécies E. heterophyla e R. raphanistrum. Os sintomas de fitotoxicidade mais elevados foram observados com metribuzin, diclosulan e imazetapir, que também apresentaram menor teor de sólidos solúveis, produtividade total e de tubérculos classe “especial”, sendo assim considerados menos seletivos. Linuron e clomazone, não proporcionaram fitotoxicidade e redução de produtividade total e de tubérculos classe “especial”, não afetaram o teor de sólidos sendo considerados mais seletivos para esta cultivar.EDUFU2018-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3826110.14393/BJ-v34n2a2018-38261Bioscience Journal ; Vol. 34 No. 2 (2018): Mar./Apr.; 279-286Bioscience Journal ; v. 34 n. 2 (2018): Mar./Apr.; 279-2861981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/38261/21908Brazil; ContemporaryCopyright (c) 2018 Luciano Ferreira Fonseca, José Magno Queiroz Luz, Ivaniele Nahas Duarte, Dalcimar Batista Wangenhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFonseca, Luciano FerreiraLuz, José Magno QueirozDuarte, Ivaniele NahasWangen, Dalcimar Batista2022-02-15T13:46:05Zoai:ojs.www.seer.ufu.br:article/38261Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-15T13:46:05Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
