Resumo: | The difficulty in managing weeds present in sunflower increases together with the crop expansion, mainly due to the few selective herbicide options. In this sense, the objective of this research was to evaluate the selectivity of the Olisun 3 and ADV 5504 sunflower cultivars to the herbicide treatments applied in pre-emergence of the crop under field conditions. The experimental design was a randomized block, 2 × 6 factorial scheme in four replicates, two cultivars (Olisun 3 and ADV 5504) and six herbicides (sulfentrazone 600 g i.a. ha-1, s-metolachlor 1920 g i.a. ha-1, trifluralin 1780 g i.a. ha-1, prometryn 1000 g i.a. ha-1, flumioxazin 40 g i.a. ha-1 and a non-treated control). The phytotoxicity (medium of 6.92 and 10.96%) in the plants was observed with 7 DAA. The ADV 5504 cultivar showed higher values of phytotoxicity (14.75%) for the herbicide S-metolachlor. Olisun 3 exhibited the largest stem diameter (23,32 mm) when prometryn was used. For head insertion height, ADV 5504 presented a higher value (1.16 m) and the herbicide S-metolachlor did not affect this variable, with a value (1.15 m) statistically similar to the control. The yield of the two cultivars was statistically similar (1891.28 and 2025.91 kg ha-1). All herbicides researched were selective to both Olisun 3 and ADV 5504 cultivars, not interfering with the final yield of sunflower grains. Therefore. it is possible to recommend these products to control weeds in this crop. |

Nesse sentido, o objetivo dessa pesquisa foi avaliar a seletividade das cultivares de girassol Olisun 3 e ADV 5504 a herbicidas aplicados em pré-emergência da cultura em condições de campo. O delineamento experimental utilizado foi feito em blocos ao acaso com esquema fatorial 2 × 6 em quatro repetições, sendo dois cultivares (Olisun 3 e ADV 5504) e seis tratamentos herbicidas (sulfentrazone 600 g i.a. ha-1, s-metolachlor 1920 g i.a. ha-1, trifluralin 1780 g i.a. ha-1, prometryn 1000 g i.a. ha-1, flumioxazin 40 g i.a. ha-1 e testemunha sem aplicação de herbicidas). Sintomas de fitointoxicação (média de 6,92 e 10,96%) nas plantas foram observados 7 DAA. A cultivar ADV 5504 apresentou valores superiores de fitointoxicação (14,75%) para o herbicida s-metolachlor. A Olisun 3 exibiu o maior diâmetro de caule (23,32 mm) quando foi utilizado o prometryn. Para altura de inserção de capítulo, a ADV 5504 apresentou valor superior (1,16 m) e o herbicida s-metolachlor não afetou tal variável, com valor (1,15 m) estatisticamente semelhante à testemunha. A produtividade dos dois cultivares foi semelhante estatisticamente (1891,28 e 2025,91 kg ha-1). Todos os herbicidas pesquisados foram seletivos para ambas as cultivares Olisun 3 e ADV 5504, não interferindo na produtividade final de grãos do girassol. Portanto é possível recomendar esses produtos para o controle das plantas daninhas nessa cultura.Universidade Federal Rural da Amazônia/UFRA2019-11-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3000Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 62 (2019): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 62 (2019): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
