Abstract
The toxic and interactive toxic effects of two agrochemicals (fosthiazate and
metalaxyl-M) and copper were investigated in this study on the photobacterium
Vibrio fischeri. The toxicities of all tested compounds were generally
comparable. The order of toxicity was: copper > fosthiazate > metalaxyl-M. The
interactive effects of fosthiazate and metalaxyl-M mixtures were found to be
additive for most of the concentration combinations tested. For the binary
mixtures of fosthiazate and copper the interactive effect was antagonistic for all
concentration combinations tested. Both agrochemicals showed a similar toxic
response, while the toxicity of copper increased significantly by the increase of
exposure time and a steep increase of copper toxicity was observed with a small
increase of its concentration.
Keywords: pesticides, agrochemicals, copper, bioassays, Vibrio fischeri,
Microtox, interactive effects.
