| Nota de conteúdo | <br/><br/>ABSTRACT<br/>Background: Competition with weeds and the lack of selective<br/>herbicides registered for birdsfoot trefoil crops affect their development<br/>and limit their productivity.<br/>Objective: This study aimed to evaluate selectivity of post-emergent<br/>herbicides for weed control in birdsfoot trefoil crops.<br/>Methods: Experiments were carried out in a greenhouse and on a field,<br/>in both vegetative and reproductive development stages of birdsfoot<br/>trefoil crops. Treatments were composed of post-emergent herbicides<br/>recommended for soybean, corn and garlic cultivation. Phytotoxicity<br/>(PHYTO), plant height (HEI), shoot dry matter (SDM) and root dry matter<br/>(RDM) were evaluated. Data were submitted to the analysis of variance<br/>and when means were significant, they were compared by the Duncan’s<br/>Test (p≤0.05). In order to determine post-emergent herbicides which were<br/>selective to the crop, those that provided PHYTO below or equal to 15%<br/>were recommended, since they did not significantly interfere with<br/>morphological variables HEI, SDM and RDM, by comparison with the<br/>control.<br/>Results: Unlike results found in the vegetative stage, birdsfoot trefoil<br/>plants were more tolerant to phytotoxic effects of herbicides imazethapyr,<br/>chlorimuron-ethyl, cloransulam-methyl and fomesafen in the reproductive<br/>stage. The variables were negatively affected by the herbicides bentazon,<br/>glyphosate and carfentrazone-ethyl, with PHYTO higher than 40% at<br/>20 days after treatment in the vegetative stage.<br/>Conclusions: Herbicides imazethapyr, chlorimuron-ethyl and<br/>flumetsulam, when applied as post-emergent ones, regardless of the<br/>development stage of the species, are selective to birdsfoot trefoil crops,<br/>without affecting crop development, whereas herbicides cloransulammethyl and fomesafen are not selective to them. <br/><br/>Keywords:<br/>Lotus corniculatus<br/>management<br/>efficiency |
