Resumo: The use of desiccants may result in seeds with high physiological and sanitary quality due to the shorter period of exposure to field adverse conditions before the maturity stage for harvest. This study evaluated the effect of chemical desiccants and harvest times on the physiological and sanitary quality of soybean seeds. The experiment consisted of a randomized block design, arranged in a factorial scheme (4 × 3) + 1, with four replications. The first factor corresponded to four desiccation (grammoxone–2 L ha-1, glufosinate–2 L ha-1, reglone–1.5 L ha-1, and saflufenacil–40 g ha-1) applied at the R7.1 phenological stage (physiological maturity and 65% moisture with three harvest times (0, 7, and 14 days after the R8 phenological stage) and additional treatment (control, application of water only, and harvest at the R8 stage), with four replications. The use of the grammoxone desiccant and seeds harvested at seven days after the R8 stage resulted in soybean seeds of the highest physiological quality, as observed for the variables germination, moisture damage, mechanical damage, and incidences of Colletotrichum sp., Phomopsis sp., Penicillium sp. Fusarium sp., Cercospora kikuchii, and Alternaria sp. Seeds harvested at the R8 + 14 stage had the greatest losses in seed quality. The use of ammonium glufosinate and saflufenacil as desiccants is not recommended due to the reduction in the physiological quality of soybean seeds.

O objetivo neste trabalho foi avaliar o efeito de dessecantes químicos e épocas de colheita sobre a qualidade fisiológica e sanitária em sementes de soja. O ensaio foi realizado em delineamento em blocos casualizados, disposto em esquema fatorial (4 × 3) + 1, sendo quatro herbicidas para a dessecação (gramoxone - 2 L ha-1, glufosinato – 2 L ha-1, reglone – 1,5 L ha-1, saflufenacil 40 g ha-1) aplicado no estádio fenológico R7.1 (maturidade fisiológica e 65% de umidade), com três épocas de colheita (0; sete e 14 dias após o estádio fenológico R8 - maturação plena), mais o controle (ausência de dessecante e colhida em R8), com quatro repetições. O uso do dessecante gramoxone e as sementes colhidas sete dias após R8 proporciona maior qualidade fisiológica de sementes de soja, conforme observado nas variáveis germinação, danos por umidade, danos mecânicos e a incidência de Colletotrichum sp., Phomopsis sp., Penicilium sp., Fusarium sp., Cercospora kikuchii e Alternaria sp.. A colheita de sementes no estádio R8+14 promove as maiores perdas na qualidade das sementes. O uso de glufosinato de amônio e saflufenacil como dessecantes não são recomendados, devido à redução na qualidade fisiológica das sementes de soja.Universidade Federal Rural do Semi-Árido2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/867410.1590/1983-21252019v32n409rcREVISTA CAATINGA; Vol. 32 No. 4 (2019); 934-942Revista Caatinga; v. 32 n. 4 (2019); 934-9421983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8674/10103Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessZuffo, Alan MarioSantos, Mariely de Abreu dosOliveira, Izabela Cristina deAlves, Charline ZaratinAguilera, Jorge GonzálezTeodoro, Paulo Eduardo2023-07-20T17:54:00Zoai:ojs.periodicos.ufersa.edu.br:article/8674Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:41.699899Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
