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

Apply to actively growing grasses prior to 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 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. Example - Juniperus horizontalis 'Blue Acres' is sensitive while cv '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.
