Toxicidad de herbicidas promisorios para el control de Dieffenbachia oerstedii en hijos de banano

potential toxicity on banana sword suckers of next treatments was evaluated between august and december of 2006: t1) absolute check, t2) carfentrazone + surfactant; t3) glyphosate + surfactant; t4) glyphosate + carfentrazone + surfactant; t5) glyphosate + ammonium sulphate + surfactatant; t6) metsulfuron metyl + carfentrazone + surfactant. a complete randomized design was used, with 20 replications for each treatment, for a total of 120 bananas suckers. the treatment with metsulfuron methyl + carfentrazone + surfactant affected growth of some suckers and caused death of a few of them. glyphosate + carfentrazone + surfactant did not differ from the absolute check. the potential of the treatment with glyphosate + carfentrazone for dieffenbachia oerstedii control in commercial fields of banana plantations is confirmed, because it provides acceptable wweed control and no damage of young banana suckers.
