Puckered Grapevine Leaves: Herbicide Drift, Virus, or Mites?

Severely puckered leaves on a potted 10-year-old grapevine (recently from Italy) can stem from:

• Herbicide drift—accidental exposure causes distortion; new growth may normalize.
• Virus diseases—persistent, no cure.
• Eriophyid mites—microscopic, feed on leaf undersides along veins.

Next Steps

1. Watch new leaves—if they emerge normal, herbicide drift is likely.
2. If distortion persists, take distorted leaves to a local nursery for hand-lens inspection.
3. Consider testing for virus if mites aren’t found.
