Is this bottom or blossom rot or what? How can I fix this?

Fruit Rots
Fruit rot results from infection by fungi, bacteria, or abiotic disorders (see abiotic diseases for information on non-parasitic fruit disorders). Some viruses also cause fruit damage, however, the rot that results from these infections is usually caused by secondary fungi or bacteria. Parasitic organisms can attack fruit directly (primary causal agent) or can attack tissue weakened either by another organism or by environmental factors (secondary causal agent). Fruit rots can occur in the field or postharvest.
Phytophthora Pod Rot. The causal agent of Phytophthora root rot, Phytophthora capsici, also attacks fruit, causing a disease known as Phytophthora pod rot.
Conditions for disease: This disease attacks fruit in the field under high rainfall and high humidity conditions, typical of a southern New Mexico summer rainy season. In these conditions, the fruit becomes watersoaked and susceptible to attack. Phytophthora capsici is splashed from the soil to the fruit and infection occurs when the fungus directly penetrats the skin. Fruit lesions usually occur on the ends of the fruit where water and fungal spores tend to accumulate.
Symptoms: Infected pods shrivel (fig. 9) and rot and white mold (mycelium of the fungus) develop inside the pod. Once inside the fruit, seeds become infested with the pathogen.
Control: The same control practices used to control Phytophthora root rot can help to control Phytophthora pod rot. Fungicide sprays are not effective.
