1 Maximum rate generally approved by EGLE. Actual rate required for control may depend on the target species and other site-specific conditions. Refer to product label. 2 Various copper sulfate products registered with MDARD (517-373-9750) may be used. 3 Granular endothall and granular 2,4-D products may not be applied within 75 feet of any well OR within 250 feet of wells less than 30 feet deep. Isolation distances are measured from the well location, not the shoreline. 4 Fluridone and penoxsulam use may be subject to Lake Management Plan and/or Evaluation protocols. Contact EGLE for current guidelines. 5 Only dyes that are labeled as herbicides must be registered with the U.SEPA and MDARD. Dye product labels which claim herbicidal properties cannot be used in waterbodies where there is an outflow.
