Resumo: | During the 1994/95 and 95/96 farming seasons, two field assays were conducted in Coimbra, Minas Gerais, to evaluate the residual effect in soil of the herbicides imazamox (50 and 100 g/ha), imazaquin (140 and 280 g/ha) and imazethapyr (100 and 200 g/ha), used in soybean, on corn and sorghum crops succeeding soybean. Bioassays using sorghum as test-plant were conducted under greenhouse conditions by using soil samples collected from plots sprayed with the herbicides in field experiments. Soil samples were collected at 90, 105, 120 and 135 days after application (DAA) for imazamox and imazethapyr and at 95, 110, 125 and 140 DAA for imazaquin. Corn and sorghum sowing was carried out in the plots previously used for soybean crop. The results obtained allowed to conclude that imazamox had the lowest residual effect in soil among herbicides evaluated, having no influence on the development of the test-plant at 120 DAA, even when the recommended dosage was doubled. However, imazethapyr applied at 200 g/ha (double recommended dosage) inhibited significantly the development of sorghum plants sowed 120 and 135 DAA. However, in field conditions, no negative effect was observed either on corn or sorghum crops sowed 150 DAA of herbicides. |

Em casa de vegetação, foram feitos bioensaios com sorgo como planta-teste, semeando-o em amostras de solo coletadas nas parcelas onde foram aplicados os herbicidas no campo. As amostras foram coletadas aos 90, 105, 120 e 135 dias após a aplicação (DAA), para imazamox e imazethapyr, e aos 95, 110, 125 e 140 DAA, para o imazaquin. Um dia após a colheita da soja, fez-se a semeadura do milho e do sorgo nas parcelas no campo anteriormente ocupadas por ela. Os resultados obtidos permitiram concluir que o herbicida imazamox apresentou o menor efeito residual entre os herbicidas avaliados, não influenciando o desenvolvimento da planta-teste quando esta foi semeada a partir dos 120 DAA dos herbicidas, até mesmo no dobro da dose recomendada. Todavia, o imazethapyr a 200g/ha (dobro da dose recomendada) apresentou sensível inibição no desenvolvimento das plantas de sorgo quando semeadas 120 e 135 DAA. Em condições de campo, não se observou nenhum efeito negativo sobre as culturas de milho ou sorgo semeadas 150 DAA dos herbicidas.Universidade Estadual de Maringá2008-07-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/429410.4025/actasciagron.v21i0.4294Acta Scientiarum.
