When to act

Walk the field every two weeks and pull and burn any hill with tiny, pale, crowded leaves on short vines.

Before you spray

No spray cures it. Plant cuttings only from healthy fields, pull and burn bushy plants, and do not plant beside a sick field.

How to prevent it

  • Take cuttings only from healthy fields with no bushy, little leaf plants.
  • Pull and burn sick hills as soon as you see them, before leafhoppers carry it on.
  • Do not plant beside a sick field, and clear volunteers and morning glory weeds around it.
  • Rotate the field with grains for a season after an outbreak.
