Comparative Sensitivity of Five Species of Macrophytes and Six Species of Algae to Atrazine , Metribuzin , Alachlor , and Metolachlor

  title={Comparative Sensitivity of Five Species of Macrophytes and Six Species of Algae to Atrazine , Metribuzin , Alachlor , and Metolachlor},
  author={James F. Fairchild and David S. Ruessler and Alvar R Carlson},
This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic plants than were the acetanilide herbicides (alachlor and metolachlor). Toxicity studies ranked metribuzin… CONTINUE READING
