Resumo: Sunflower (Helianthus annuus) sown offseason, after soybean crop (Glycine max), is affected by the competition imposed by volunteer plants. Two experiments were carried out to evaluate the control of volunteer soybean plants in sunflower crops. The sulfentrazone herbicide (75 g ha-1, 100 g ha-1 and 250 g ha-1) causes phytotoxicity to sunflower immediately after application, however, plants recover, with no yield losses. These doses do not cause the total death of volunteer soybean plants, but temporarily paralyzes their growth, avoiding the competition with the sunflower crop. The glufosinate ammonium and ametryn herbicides are effective in controlling volunteer soybean plants, however, symptoms of phytotoxicity in the sunflower crop are high, reflecting in losses of dry weight biomass and crop yield. The other treatments do not provide satisfactory control of volunteer soybean plants and even reduce the sunflower dry weight biomass and yield.

Dois experimentos foram conduzidos a fim de avaliar o controle de plantas voluntárias de soja em cultivo de girassol. O herbicida sulfentrazone (75 g ha-1, 100 g ha-1 e 250 g ha-1) causa fitotoxicidade ao girassol logo após a aplicação, porém, há recuperação das plantas, sem prejuízo à produtividade da cultura. Essas mesmas doses não causam a morte total das plantas voluntárias de soja, entretanto, paralisam, temporariamente, seu crescimento, evitando a competição com a cultura do girassol. Os herbicidas amônio glufosinato e ametryn são eficazes no controle de plantas voluntárias de soja, contudo, os sintomas de fitotoxicidade na cultura do girassol são elevados, refletindo em perdas de massa de matéria seca e produtividade da cultura. Os demais tratamentos não proporcionam controle satisfatório das plantas voluntárias de soja e ainda causam redução na massa de matéria seca e produtividade do girassol.Escola de Agronomia - Universidade Federal de Goiás2015-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/33999Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 3, Jul./Sep. 2015; 274-281Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 3, jul./set. 2015; 274-281Pesquisa Agropecuária Tropical; v. 45, n. 3, jul./set. 2015; 274-2811983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/33999/18939Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessBrighenti, Alexandre Magno2020-07-13T16:27:49Zoai:ojs.revistas.ufg.br:article/33999Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T16:27:49Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false
