Where the soil pH has been adjusted to 6.0 or above, additional soil applied calcium does not correct the disorder. Addition of a foliar spray directly to the developing fruit may reduce the incidence of blossom end rot. Use calcium nitrate at the rate of 10-15 lb. per 100 gallons of water per acre. Repeat at 7-10 day intervals. Practice a 3-4 year crop rotation.
Bacterial spot Use resistant varieties wherever possible.
Check seed suppliers for newly released resistant varieties. Agri-strep cannot be applied to plants outside of the seedbed. Use copper sprays to reduce the rate of bacterial spread in the field. The combination of a copper fungicide plus maneb will increase the effectiveness of the application. Avoid consecutive seasons with peppers or tomatoes in the same field.
