description Weeds are one of the major problems in globe artichoke production. For that reason, it is important to increase knowledge on herbicide use to improve weed management in this crop. The objective of this study was to evaluate the weed control efficacy of herbicides in the early stages of artichoke cultivation, and their phytotoxicity on the crop. The trial was conducted at the FCA, UNR. Seeds of the ‘Madrigal' hybrid were sown in October and transplanted in November 2014. Treatments were: (I) pre-emergence: S-metolachlor, Oxyfluorfen, Pendimethalin, Linuron, Prometryn; (2) post-emergence: Linuron, Prometryn. The percentageof control efficacy of Portulaca oleracea, Lamium amplexicaule, Eleusine indica, Digitariasanguinalis, Echinocloa sp., Chenopodium album and Amaranthus quitensiswas calculated. Phytotoxicity was measured with an arbitrary scale (1:not affected, 2:slightly affected; 3:affected; 4:greatly affected). The design was in randomized blocks with 3 replications, and Shapiro-Wilks and Friedman tests were performed. Highly significant differences in control efficacy were observed between the pre-emergence herbicides tested, in the two measurement dates. S-metolachlor controlled 66% of weeds, Linuron 82%, Pendimethalin 89%, without causing phytotoxicity. Oxyfluorfen controlled 93% of weeds, but phytotoxicity was observed (3 in the first measurement, 2 in the second). Although Prometryn controlled 83% of weeds, phytotoxicity was 4. Highly significant differences were observed between post-emergence treatments only in the second measurement date in E. indica, D.sanguinalis, Echinochloa sp. Linuron controlled 93.7% of weeds, and caused level-3 phytotoxicity in both dates. Prometryn achieved 92% weed control, with level-4 phytotoxicity. In the experimental conditions, the herbicides which provided efficient weed control without phytotoxic effects on artichoke plants were Pendimethalin and Linuron when sprayed in preemergence.

In the experimental conditions, the herbicides which provided efficient weed control without phytotoxic effects on artichoke plants were Pendimethalin and Linuron when sprayed in preemergence. Uno de los principales problemas productivos del alcaucil son las malezas, siendo necesario disponer de herbicidas que efectúen un adecuado control. Se evaluó la eficacia de herbicidas en el control de malezas en etapas iniciales del cultivo, y la fitotoxicidad sobre el mismo. El experimento se realizó en la FCA, UNR, en Madrigal, sembrado en octubre y trasplantado en noviembre de 2014. Se aplicaron en preemergencia de malezas: S-metolacloro, Oxifluorfen, Pendimetalin, Linuron, Prometrina y además, los dos últimos en posemergencia. Fue analizado el porcentaje de eficacia de control de los herbicidas sobre Portulaca oleracea, Lamium amplexicaule, Eleusine indica, Digitaria sanguinalis, Echinocloa sp., Chenopodium album y Amaranthus quitensis. La fitotoxicidad se midió con escala arbitraria (1:no afectadas; 2:levemente afectadas; 3:afectadas; 4:muy afectadas). El diseño fue en bloques al azar con 3 repeticiones y pruebas de Shapiro-Wilks y Friedman. Se observaron diferencias altamente significativas en eficacia de control entre los herbicidas evaluados en preemergencia, en ambas fechas de medición. S-metolacloro controló 66% de malezas, Linuron 82% y Pendimetalin 89%, sin causar fitotoxicidad en plantas de alcaucil. Oxifluorfen controló 93%, con fitotoxicidad 3 en la primera medición y de 2 en la segunda. Si bien la Prometrina controló 83%, la fitotoxicidad fue de 4. Se observaron diferencias altamente significativas en tratamientos posemergencia en la segunda fecha de medición en Eleusine, Digitaria y Echinocloa. Linuron controló el 93,7% con fitotoxicidad 3 en ambas fechas. Prometrina el 92% con fitotoxicidad de 4. En las condiciones del experimento, los herbicidas destacados fueron Pendimentalin y Linuron en preemergencia. Um dos principais problemas na produção da alcachofra são as plantas daninhas, sendo necessário ter herbicidas que realizem um bom controle. Foram avaliadas tanto a eficácia dos herbicidas no controle de plantas daninhas, nos estágios iniciais da cultura quanto a sua fitotoxicidade. O experimento foi realizado na FCA, UNR, em Madrigal, plantado em outubro e transplantado em novembro de 2014. As ervas daninhas foram tratadas em pré-emergência com: S-metolacloro, Oxifluorfen, Pendimetalin, Linuron, Promethrin e também as duas últimas em pós-emergência. Foi analisada a porcentagem de eficácia de controle de herbicidas em Portulaca oleracea, Lamium amplexicaule, Eleusine indica, Digitaria sanguinalis, Echinocloa sp., Chenopodium album e Amaranthus quitensis. A fitotoxicidade foi mensurada em uma escala arbitrária (1:não afetado; 2:levemente afetado; 3:afetado; 4:muito afetado). O delineamento foi em blocos ao acaso, com 3 repetições, com os testes de Shapiro-Wilks e Friedman. Diferenças altamente significativas na eficácia do controle foram observadas entre os herbicidas avaliados na pré-emergência, nas duas datas de medição. O S-metolacloro controlou 66% das plantas daninhas, Linuron 82% e Pendimetalin 89%, sem causar fitotoxicidade em plantas de alcachofra. O oxifluorfen controlou 93%, com fitotoxicidade 3 na primeira medição e 2 na segunda. Embora o Prometrine tenha controlado 83%, a fitotoxicidade foi 4. Diferenças altamente significativas foram observadas nos tratamentos pós-emergência na segunda data de medição, em Eleusine, Digitaria, Echinocloa, Linuron controlou 93,7% e fitotoxicidade 3 em ambas as datas. Prometrina 92% e fitotoxicidade de 4. Sob as condições do experimento, os herbicidas que se destacaram foram Pendimentalin e Linuron aplicados em pré-emergência.
