| description | Although pesticide contamination of surface waters normally occurs in the form of mixtures, the toxicity
and interactions displayed by such mixtures have been little characterized until now. The present study
examined the interactions prevailing in equitoxic and non-equitoxic binary mixtures of formulations of
glyphosate (Glifoglex®) and cypermethrin (Glextrin®) to the tenspotted livebearer (Cnesterodon decemmaculatus),
a widely distributed South American fish. The following 96 h-LC50s were obtained when
pesticide formulations were tested individually: Glifoglex® 41.4 and 53 mg ae glyphosate/L; Glextrin®
1.89 and 2.60 mg cypermethrin/L. Equitoxic and non-equitoxic mixtures were significantly antagonic in
all combinations tested. The magnitude of the antagonism (factor by which toxicity differed from concentration
addition) varied between 1.37 and 3.09 times in the different non-equitoxic mixtures tested.
Antagonism was due to a strong inhibition of cypermethrin toxicity by the glyphosate formulation, the
toxicity of the cypermethrin-based pesticide being almost completely overridden by the glyphosate
formulation. Results obtained in the current study with fish are radically opposite to those previously
observed in tadpoles where synergy was observed when Glifoglex® and Glextrin® were present in
mixtures (Brodeur et al., 2014). |
