ABSTRACT:       Competition with weeds and lack of selective herbicides registered for bird’s-foot trefoil crops affect their development and limit productivity. Therefore, this study aimed at evaluating selectivity of pre-emergent herbicides in bird’s-foot trefoil crops. Experiments were carried out in a greenhouse and on a field where the following herbicides were evaluated and compared with the control: imazethapyr, diclosulam, flumetsulam, metribuzin, s-metolachlor, sulfentrazone, clomazone and isoxaflutole. Regarding variables under evaluation, phytotoxicity (PHYTO), plant stature, dry mass of the aerial part (DMAP) and dry mass of roots (DMR) were evaluated in the greenhouse, while plant population, PHYTO and DMAP were assessed on the field. The criterion  to  determine  selectivity  were:  PHYTO  below  15%  and  not  reducing  the  plant  population  nor  morphological  variables,  by comparison with the control. The variables were negatively affected by the herbicides clomazone, metribuzin, isoxaflutole, diclosulam, s-metolachlor, in which the crop population was reduced in 98, 92, 83, 63, 48 and 22%, respectively. Following the criteria, only the herbicide sulfentrazone as a pre-emergente is selective to bird’s-foot trefoil crop (cultivar ‘São Gabriel’).

RESUMO:       A  competição  com  plantas  daninhas  e  a  falta  de  herbicidas  seletivos  registrados  para  a  cultura  do  cornichão  comprometem  o  desenvolvimento  e  limitam  a  produtividade  da  cultura.  Diante  disso,  objetivou-se  avaliar  a  seletividade  de  herbicidas pré-emergentes à cultura do cornichão. Foram conduzidos experimentos em casa de vegetação e campo, avaliando-se os herbicidas imazethapyr, diclosulam, flumetsulam, metribuzin, s-metolachlor, sulfentrazone, clomazone e isoxaflutole, mais uma testemunha sem aplicação. As variáveis avaliadas foram fitotoxicidade (FITO), estatura de plantas, massa seca da parte aérea (MSPA) e de raiz (MSSR), em casa de vegetação; e, população de plantas, FITO e MSPA no campo. Os critérios para determinar a seletividade foram: FITO inferior a 15% e, a não redução da população de plantas e das variáveis morfológicas comparativamente  a  testemunha.  As  variáveis  foram  afetadas  negativamente  pelos  herbicidas  clomazone,  metribuzin,  isoxaflutole, diclosulam, s-metolachlor, que reduziram a população de plantas 98, 92, 83, 63, 48 e 22%, respectivamente. Com base nos critérios apenas o herbicida sulfentrazone aplicados em pré-emergência é seletivo para a cultura do cornichão, cultivar São Gabriel.
