Dimethomorph is only slightly toxic to mammals. The LD50, the dose which kills half of the test animals who consume it, is 3900 mg/kg for rats, 5000 mg/kg for male mice, and 3700 mg/kg for female mice (2). The LD50 for rats whose skin is exposed to dimethomorph is greater than 2000 mg/kg (2, 5). The concentration of dimethomorph in air which is fatal to half of the animals tested, the LC50, is greater than 4.24 mg/l air for rats. Dimethomorph is non-irritating to rabbit eyes and skin (1). It is non-sensitizing to guinea pigs' skin (3).
