It is commonly used in citrus (orange and grapefruit) orchards as well as sugar cane and pineapple farms. It is slightly toxic by acute oral and inhalation exposure and practically nontoxic by acute dermal exposure. It is considered to be moderately irritating to the skin and substantially irritating to the eye. There was no evidence of carcinogenic effects in an 18-month chronic/oncogenicity study in mice at dose levels up to and including 800 ppm (216 mg/kg/day). "}]
