Bacterial Blight Management in Pepper

Bacterial blight causes water-soaked angular leaf spots and blighting, spread by water, tools, and infected seed. This page covers bacterial blight in pepper.

Common crops affected

Why it matters

It blights foliage and pods and can be seed-borne. Bacterial diseases can't be cured once tissue is infected — rely on clean seed, rotation, and sanitation, with protective inputs supporting.

When it appears

Warm, wet, windy weather.

How to identify it

  • Water-soaked angular spots, often with yellow halos
  • Spots merging into blighted dead patches in wet weather
  • Streaking on stems; infected seed in some crops

How to manage it

  1. Use clean seed and resistant varieties; rotate; avoid working wet plants.
  2. Remove infected debris.
  3. Use Spore Control as a supporting protective input during wet, high-risk periods.

Integrated management. This is a bacterial / no-cure or indirect problem — Vegalab products play a supporting role in an integrated program (plant health, prevention, protection) and are not a cure. Combine with sanitation, clean material, rotation and cultural controls.
