Genotoxic effects of the pesticides Rubigan, Omite and Rovral in root-meristem cells of Crepis capillaris L.

Three pesticides have been studied for their genotoxicity by the use of assays in the plant Crepis capillaris, aimed at measuring chromosomal aberrations, micronuclei and sister chromosome exchange (SCE). The fungicides Rubigan 12 EC (fenarimol) and Rovral 25 Flo (iprodione) and the insecticide Omite 57 E (propargite) are all widely used nowadays. The aim of our study was to evaluate the genotoxic effects of these pesticides at concentrations corresponding to those applied in agricultural practice.

Comparative genotoxicity of the herbicides Roundup, Stomp and Reglone in plant and mammalian test systems.

The genotoxicities of the herbicides Roundup (glyphosate), Stomp (pendimethaline) and Reglone (diquat), were compared in plant (Crepis capillaris L.) and mouse bone marrow test systems using chromosomal aberrations and micronuclei. Roundup did not induce chromosomal aberrations or micronuclei in either test system.
