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

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).
