Metalaxyl is a fungicide that inhibits protein synthesis in fungi.1,2 It inhibits the growth of potato blight (P. infestans) fungal isolates from Serbian potato fields (EC50s = 0.3-3.9 μg/ml).1 Metalaxyl (300 and 1,000 μg/ml) induces formation of chromosomal aberrations in human lymphocytes.3 It exhibits aquatic toxicity against S. quadricanda, D. magna, and D. rerio (IC50s = 222.89, 471.95, and 241.98 mg/L, respectively).4 Metalaxyl also induces tremors, twitches, tonic extension, ataxia, and hypnosis, symptoms of CNS poisoning, and lethality in rats (LD50s = 265 and 288.8 mg/kg for female and male rats, respectively).2
