ATM/Chk2 and ATR/Chk1 Pathways Respond to DNA Damage Induced by Movento 240SC and Envidor 240SC Keto-Enol Insecticides in the Germarium of .

DNA damage response (DDR) pathways in keto-enol genotoxicity have not been characterized, and few studies have reported genotoxic effects in non-target organisms. The present study shows that concentrations of 11.2, 22.

DNA Damage Assessment in Zebrafish Embryos Exposed to Monceren(®) 250 SC Fungicide Using the Alkaline Comet Assay.

Monceren 250 SC is a commercial fungicide with the active ingredient 1-(4-chlorobenzyl)-1-(cyclopentyl)-3-phenylurea, also known as pencycuron. This compound inhibits the growth of fungi as Rhizoctonia solani that invades potato, rice, and cotton or as Pellicularia spp, which contaminates lettuce and tomato crops. In this study, we assessed genotoxicity or DNA damage by the alkaline comet assay in zebrafish blastula-stage embryos exposed to 250 to 1250 μg/mL of the Monceren fungicide or to Bleomycin (0.
