Management of the grey slug, Deroceras reticulatum (Müller) (Pulmonata: Stylommatophora), in Argentina, has been limited to the use of pelleted toxic baits containing metaldehyde. The most important molluscicides in the Argentinean market are Clartex (Rizobacter Argentina S.A.), Acay (Acay Agro S.R.L.) and Babotox (Huagro S.A.). The aim of this work was to investigate the efficacy and dose of those commercial baits against D. reticulatum. The molluscicides (Acay, Clartex and Babotox), at doses of 3, 4 and 5 kg/ha and dry and moist soil conditions were investigated in terraria trials. The efficacy of the molluscicides and dose level was also evaluated in field experiments at two sites at Balcarce in the southeast of Buenos Aires Province, Argentina. The proportions of dead slugs did not show significant interactions between soil conditions, molluscicides and their dose (p>0.05). The proportion of dead slugs, in moist conditions, was significantly lower than under dry conditions (p
