Accidental Roundup on Trees/Shrubs: Little Hope After 24 Hours

If glyphosate (Roundup) has been on leaves of redbud, azaleas, or rhododendrons for >24 hours, systemic translocation has occurred. Prayer is about all that's left. Some plants may resprout from roots if not fully killed.

Immediate Action (if <24 hrs)

• Hose off foliage thoroughly.
• Apply activated charcoal slurry to leaves (may adsorb some herbicide).

Prevention: Use separate, clearly labeled sprayers for herbicides.
