St. Johns River Treatment Schedule

Treatment Date and Areas: September 18, 2017 - September 22, 2017                       

Spray operations will be conducted by USACE personnel on the St. Johns River between the Memorial Bridge in Palatka, and the Shands Bridge in Green Cove Springs.

Herbicide Information: Foliar treatments for floating plants are conducted with Diquat, 2,4-D, Penoxsulam, Carfentrazone, Imazamox, Triclopyr, Flumioxazin, Imazapyr, and/or Glyphosate.
Special Instructions: Areas spot treated with Diquat should not be used for 1 day for drinking water, livestock and domestic animal watering or irrigation of non-food crops and 5 days for food crops. There are no restrictions for Glyphosate treated areas except for a 48-hour waiting period within 0.5 mile of an active potable water intake (drinking water).
Note: Generally, 2,4-D will be used only in areas where water intakes are at least 0.5 miles or more away from the treatment site. If treatment occurs within 0.5 mile of a water intake the treated sites will be posted with signs stating that there is a 3-week restriction for irrigation and potable water use.

The Schedule of Operations summarizes plant control that FWC contractors and field biologists have proposed to accomplish for the following 1-2 weeks. The schedule shows types of plants and estimated amounts that the contractor plans to control along with control methods for a particular waterbody. Conditions such as rain, high winds, or equipment failures can result in some or all of this planned work not being completed in which case it will be rescheduled for a future date. The Schedule of Operations for a particular period may include several waterbodies. In some instances, more than one contractor may be scheduled to work on the same waterbody but on different plant species, in different areas, or utilizing a different control method.
