You can minimize problems with bacterial spot by following these tips:
- Select resistant varieties
- Purchase disease-free seed and transplants.
- Treat seeds by soaking them for 2 minutes in a 10% chlorine bleach solution (1 part bleach; 9 parts water). Thoroughly rinse seeds and dry them before planting.
- Mulch plants deeply with a thick organic material like newspaper covered with straw or grass clippings.
- Avoid overhead watering.
- Remove and discard badly infected plant parts and all debris at the end of the season.
- Spray every 10-14 days with fixed copper (organic fungicide) to slow down the spread of infection.
- Rotate peppers to a different location if infections are severe and cover the soil with black plastic mulch or black landscape fabric prior to planting.
