BRENES-PRENDAS, Steven  e  AGUERO-ALVARADO, Renán. Toxicity of banana suckers by promisory herbicides for the control of Dieffenbachia oerstedii. Agron. Mesoam [online]. 2012, vol.23, n.1, pp.47-53. ISSN 2215-3608.

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.
