Toxicity Profile
Route of ExposureInhalation (2) ; oral (2) ; dermal (2) ; eye contact (2)
Mechanism of ToxicityIts mode of action is elongase inhibition, and inhibition of geranylgeranyl pyrophosphate (GGPP) cyclisation enzymes (3).
MetabolismNot Available
Toxicity ValuesLD50: 2953 mg/kg (Oral, Rat) (5) LD50: 3667 mg/kg (Dermal, Rabbit) (5)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesIt is used to control weeds in corn, and is particularly useful as a replacement for atrazine in the case of some important weeds. (3).
Minimum Risk LevelNot Available
Health EffectsARDS/acute lung injury, burns of the esophagus or gastrointestinal tract can result from acetochlor poisoning (4).
SymptomsAcetochlor is mildly irritating to the skin and eyes. Exposure to metalaxyl often results in such nonspecific symptoms as headache, dizziness, weakness, and nausea. Acetochlor poisoning can produce an allergic hypersensitivity dermatitis or asthma with bronchospasm and wheezing with chronic exposure (4).
