  51. 51. Leading The Way SPECIAL CONSIDERATIONS in Aquatic Systems Aquatic Weeds 4.1.51 USE GOOD WORK PRACTICES and PROPER HERBICIDE STEWARDSHIP:the label is the law! Protect ground water by protecting surface water Avoid drift, leaching and run-off Avoid unintentional contamination of water Check for label changes and read and follow the label
  52. 52. Leading The Way SPECIAL CONSIDERATIONS in Aquatic Systems Aquatic Weeds 4.1.52 WHAT IS THE WATER USED FOR? There may be many answers The answer(s) will affect your methods and choice of materials Drinking, Swimming, Irrigation, Live Stock etc. THE LABEL WILL WARN YOU ON WHAT TO LOOK FOR
  53. 53. Leading The Way SPECIAL CONSIDERATIONS in Aquatic Systems Aquatic Weeds 4.1.53 WHAT ARE THE DOWNSTREAM USES OF THE WATER? Crops could be damaged Salt marshes, estuaries could be impacted/affected Industrial plants could be affected Drinking water supply could be affected
