Effects of ten agricultural fungicides were tested on Xenopus tropicalis embryos.
Strobilurin fungicides showed strong lethal and teratogenic effects on embryos.
Lowest LC50 and TC50 were observed for strobilurins in ten fungicides.
μg/L level of toxic concentrations for strobilurins was environmentally relevant.
Teratogenicity shared similar dose–effect relationship and main phenotypes.
