We investigated methiozolin acute toxicity using with Sprague-Dawley rats. The results of acute oral toxicity using rats showed $LD_{50}$ value of over 2,000 mg/kg bw for methiozolin. The calculate acute dermal $LD_{50}$ value of methiozolin was over 4,000 mg/kg. The skin irritation test showed moderately irritation and weak response of eye irritation test was observed in this experimental condition. According to these results, We concluded that methiozolin was Category IV in GHS chemical classification for acute toxicity. Future, we need more chronic toxicity test for safety.
