Roundup Original Nonionic surfactant may be used. When adding surfactant use 0.5 percent by volume (2 qt/100 gal) of a surfactant containing at least 70 percent active ingredient. In addition to nonionic surfactant dry ammonium sulfate at 1 to 2 percent by weight (8.5 to 17 lb/100 gal) may increase performance. If using ammonium sulfate add it to tank first and completely dissolve before adding surfactant or pesticides.

Glyfos Xtra No additional surfactant or buffering agents are needed or recommended. Do not add surfactant or buffering agent when Glyfos Xtra is the only pesticide used. Dry ammonium sulfate at 1 to 2 percent by weight (8.5 to 17 lb/100 gal) may increase performance.

Glyphomax Plus
Roundup Ultra Do not add surfactant or buffering agents if Glyphomax Plus or Roundup Ultra is the only pesticide used. Dry ammonium sulfate at 1 to 2 percent by weight (8.5 to 17 lb/100 gal) may increase performance. If using ammonium sulfate add it to tank first and completely dissolve before adding pesticides.

Roundup UltraMax Do not add surfactant or buffering agent when Roundup UltraMax is the only pesticide used unless directed otherwise. In addition to surfactant dry ammonium sulfate at 1 to 2 percent by weight (8.5 to 17 lb/100 gal) may increase performance. If using ammonium sulfate add it to tank first and completely dissolve before adding surfactant or pesticides.

Touchdown
Touchdown 5 A nonionic surfactant may be used at levels up to 0.25 percent by volume (1qt/100 gal). The surfactant should contain at least 75 percent active ingredient. Control may be improved by adding dry ammonium sulfate at 1 to 2 percent by weight (8.5 to 17 lb/100 gal). Liquid formulations of ammonium sulfate may be used at equivalent rates.
