Abstract
We investigated the mutagenicity of methiozolin, newly developed herbicide, in vitro reverse mutation test using Salmonella typhimurium and Escherichia coli, chromosome aberration test using chinese hamster lung (CHL) cells and in vivo micronucleus test of mice. In the reverse mutation test, the methiozolin did not induce mutagenicity in Salmonella typhimurium TA98, TA100, TA1535, TA1537, Escherichia coli WP2uvrA with and without metabolic activation at $5,000{\mu}g$/plate. In the chromosome aberration test, the results showed no incidence of increased structural and numerical chromosome abberrations at any doses tested (80, 40, $20{\mu}g$/mL). In micronucleous test, the ratio of micronuclei was measured in polychromatic erythrocytes with treated methiozolin for ICR mice. No incidence of increased micronuclei were observed in polychromatic erythrocytes (1,500, 1,000, 500 mg/kg). Based on these results, we concluded that methiozolin has no mutagenic toxicity in vitro and in vivo systems.
