The Solar Farm 2.0 developer will be planting the Solar Farm 2.0 site next week.  On May 7, 2021, they will spray an herbicide mixture to prepare the site.Here are the details they provided:

Glyphosate 41 herbicide and/or Ranger Pro.  They are both generic glyphosate-based herbicides. Ranger Pro includes a water-based surfactant in their formulation.    We will be adding a methylated seed oil for a surfactant.  We will not be using a spray dye in the mix to avoid residue on the panels.
