Precautions

• PPI or PRE - Use ONLY on transplanted cabbage, cauliflower, and broccoli.
• Use ONLY one application per year.
• Use the lower rate on light soils (coarse textured to sandy and sandy loam).
• Apply to well worked soil that is dry enough to permit thorough incorporation to a depth of 2.5-5.0 cm.
• Incorporate the same day as applied.
• Damage to subsequent cover crops can be reduced by tillage across the rows after harvest. Small grains seeded in the fall may be stunted but not otherwise affected.
• Do NOT harvest within 60 days.

Precautions

• PRE to weeds - Apply after transplanting within 2 days, before weeds emerge.
• Use the higher rate for heavier weed pressure.
