**Table 2.2-1. Corn herbicides and their restrictions.**
Trade name	Common name	Manufacturer	Restricted-use pesticide¹	Water quality advisory²	Worker reentry (hours)³
Only licensed applicators may purchase and apply restricted-use pesticides. To become licensed, contact the Pennsylvania Department of Agriculture. These herbicides have properties that may result in ground or surface water contamination. Do not apply them in areas where soils are permeable or coarse and groundwater is near the surface. Practices should be followed to minimize the potential for dissolved runoff and/or runoff erosion. See the herbicide label for specific restrictions. If soil-applied products are injected or incorporated at application time, under certain circumstances the Worker Protection Standard allows workers to enter the treated area if they will have no contact with anything that has been treated. Personal protective equipment is required for early entry to treated areas if contact treated soil, plants, or water is involved. For use only on IMI (IR/IT) or Clearfield (CL) corn hybrids. For use on glufosinate-resistant corn hybrids only. For use only on IMI (IR/IT) or Clearfield (CL) corn hybrids.
