Phytophthora Control in Peppers

For phytophthora in peppers, Vegalab recommends scouting and a natural program built on **Spore Control**. Apply Spore Control preventively under wet conditions with thorough coverage; improve drainage and avoid overwatering. Established infection is managed, not cured.

Common crops affected

  • Peppers

Why it matters

Phytophthora crown and root rot collapses peppers fast in wet, poorly drained ground.

When it appears

Preventively ahead of wet periods; manage drainage first.

How to identify it

  • Wilting despite moist or wet soil; plants that don't recover after irrigation.
  • Dark, rotting roots and reddish-brown crown or collar lesions.
  • Water-soaked foliar or fruit lesions that expand rapidly in wet weather.

How to manage it

  1. Apply Spore Control preventively under wet conditions with thorough coverage;
  2. improve drainage and avoid overwatering.
  3. Established infection is managed, not cured.
  4. Monitor early, treat at the right window above, and use cultural measures (sanitation, airflow/drainage or resistance/rotation as relevant).
