  • Characterized by powdery, white spots powdery mildew infects leaves, buds, and other young tissue affecting product quality.
  •  Hemp powdery mildew is caused by the fungus Podosphaera macularis and is identified by its upright chains of barrel-shaped spores.
  • Powdery mildew is predominantly a greenhouse disease.
  • There are no fungicides labeled for use with powdery mildew of industrial hemp.
