Precautions (For more information, see Chapter 4. Herbicides Used in Ontario, page 23 and Chapter 5. Notes on Adjuvants, page 69).

  • Apply POST to actively growing grasses before tillering.
  • Apply at 0.6 L/ha (0.24 L/ac) at 2-5 leaf stage of volunteer corn.
  • Apply at 0.8 L/ha (0.32 L/ac) at 2 -5 leaf stage of volunteer wheat and barley.
  • Apply at 1 L/ha (0.4 L/ac) at 2-5 leaf stage of annual grasses (2-4 leaf for foxtails).
  • Apply at 2 L/ha (0.8 L/ac) at 3-5 leaf stage of quackgrass & wirestem muhly.
  • Thorough preplant tillage, fragmenting quackgrass rhizomes improves control.
  • Do NOT cultivate between rows until 5 days after application.
  • Consult the label for list of tolerant and sensitive species. Use as a directed application in sensitive species to avoid contact with leaves and green tissue. Some blue junipers (e.g. 'Bar Harbour', 'Blue Acres', and 'Blue Rug') can be injured by over-the-top applications.
  • Caution- there are differences between cultivars in sensitivity to VENTURE L, (e.g. Juniperus horizontalis 'Blue Acres' is sensitive while Juniperus horizontalis 'Plumosa Compacta' is tolerant).
  • Test on samples of each cultivar not specifically listed on the label before using the herbicide or use as a directed application.
