Mango Tree Black Sooty Mold: Neem Oil for Scale/Aphids

Diagnosis

Thick black powder on upper leaf surfaces (washes off with effort) = sooty mold on honeydew from scale/aphids.

Treatment

  • Pure Neem Oil (Dyna-Gro) – kills insects, prevents mold return.
  • New growth will be clean; old mold weathers off.
  • Spray blooms for better fruit set.

Don’t scrub every leaf; treat the source.
