PHYSICAL METHODS OF CONTROL, RAKING, CRAGGING, PULLING, AND UNDERWATER MOWING HAVE BEEN USED MAINLY ON FLOATING MASSES OF ALGAE AND ROOTED AQUATltS. ECOLOGICAL CONTROL OF ALGAE INVOLVES LIMITATION OF ONE eR MORE OF THE FACTORS NECESSARY FOR GROWTH AND REPRODUCTION: LIGHT OR NUTRIENT MATERIAL. ONLY TWO CHEMICALS ARE WIDELY USEO TO CONTROL ALGAE IN WATER SUPPLIES, COPPER SULFATE AND CHLORINE. IN EXCESSIVE CONCENTRATIONS COPPER SULFATE MAY POISON FISH AND OTHER AQUATIC LIFE. APPROXIMATELY 300 CHEMICALS WERE SCREENED FOR TOXICITY AND THEIR EFFECTIVENESS COMPARED WITH THAT OF COPPER SULFATE.
