Resumo: This study aimed to evaluate the influence of imidazolinone herbicides, usually applied to rice for control of red rice, on traits related to the physiology of winter crops. The experiment was installed in randomized blocks design, arranged in a 3 x 2 factorial scheme, with three replications. The first factor was composed by herbicide rates (0, 1 and 2 x the recommended dose) and factor B by the herbicides (imazethapyr + imazapic and imazapic + imazapyr) applied in pre-emergence of rapeseed, fescue, ryegrass, birdsfoot trefoil, white clover and vetch. At 60 days after emergence, shoot dry mass (g pot-1), photosynthesis rate, CO2 concentration in leaf mesophyll, consumed CO2, stomatal conductance of water vapor, transpiration rate, temperature gradient and water use efficiency were valuated. The mixture of imazapic + imazapyr caused death of all species tested, except vetch. The mixture of imazethapyr and imazapic caused reduction in dry mass for all plant species and plant death of rapeseed, independent of dose. Physiological traits were influenced by the action of herbicides and doses. Vetch performed better under application of the herbicides.

O delineamento experimental utilizado foi de blocos casualizados, arranjado em esquema fatorial 3 x 2, com quatro repetições. O fator A foi constituído pelas doses dos herbicidas (0, 1 e 2 vezes a dose recomendada) e o B pelos herbicidas (imazethapyr + imazapic e imazapic + imazapyr) aplicados em pré-emergência de canola, festuca, azevém, cornichão, trevo branco e ervilhaca. Aos 60 dias após a emergência das plantas foram determinadas a massa seca da parte aérea, taxa de fotossíntese, concentração interna de CO2 no mesófilo foliar, CO2 consumido, taxa de transpiração, condutância estomática de vapores de água, eficiência no uso da água e gradiente térmico. O imazapic + imazapyr causou a morte de todas as espécies testadas, com exceção da ervilhaca. A mistura de imazethapyr + imazapic ocasionou redução de massa seca em todas as espécies e morte das plantas de canola, independente da dose avaliada. As características fisiológicas foram influenciadas pela ação dos herbicidas e das doses. Aervilhaca apresentou melhor comportamento frente aos herbicidas.Departamento de Diagnóstico e Pesquisa Agropecuária.
