My green pepper leaves are just falling off. The plants look bad. We have had a lot of rain and cool weather. The blooms fall off too.

They are probably infected with wilt. disease, which may be fungal (Fusarium or Verticillium wilts) or bacterial. All of these will affect any plant in the nightshade family, which includes tomatoes, peppers and eggplants.

Generally, there is no cure once your plants become affected with wilt. In most cases, the infected plants should be disposed of and the beds solarized (https://www.gardeningknowhow.com/garden-how-to/projects/how-to-solarize-garden-beds-to-eliminate-garden-pests-in-the-soil.htm) to prevent future issues. That being said, many fungal issues can be treated with a standard fungicide, should you wish to try this route first. I personally like neem oil as it is both a fungicide and a pesticide, but is food safe, beneficial bug safe and organic.
