Why are my beans turning brown?
One of the most common reasons is a fungus infection. Beans are prone to a fungal disease known as Anthracnose.

In green beans, rust is caused by a fungus that is spread by the wind, rainwater, animals, insects and even humans. The disease develops best when it is hot, between 18 and 25°C. The fungus lives on the soil and stubble. When plant growing is very dense, the rust spreads from plant to plant due to leaf rubbing.

Nutrient Deficiency or Toxicity
Green beans need the proper amount of nutrients to grow. Too much or too little of a certain nutrient will result in a stunted or dying plant. Getting a soil test done before planting is the best way to know what nutrients to add to the soil.
Fungal Diseases
Anthracnose is a fungal disease that causes dark brown lesions on the leaves and all other visible parts of the bean plant. Pink slime can appear on the spots. Anthracnose is carried in seeds, and is aggravated by cool, wet weather. Once it develops it spreads by spores. Rotate crops every three years and remove infected plant debris.
Bacterial Diseases
Brown spot is a bacterial disease that appears as small, circular brown spots on the leaves. The spots have a ring of lighter green or yellow around them. Brown spot spreads by wind, with the bacteria coming from infected weeds. Humid, gray weather causes the spots to spread more rapidly.
Insects and Nematodes
Spider mites suck the juices from leaves, causing them to turn yellow, then brown, and die. Spider mites create a white stippling on the tops of leaves, and make webs on the undersides of leaves. Wash the mites from the leaves when you see them. Keep ladybugs to eat the mites.
