What Causes Brown Spots on Green Beans?

What are the common causes for brown spots on green beans?

Brown spots on green beans can occur due to several reasons including: 

Aged 

A few brown spots here and there on a bunch of green beans indicate that they’re becoming slightly aged and won’t be the freshest beans you’ll eat. However, it does not imply you should or cannot consume them.

Bacteria

Bacteria can grow on green bean pods when they are left out at warm temperatures. This can cause the pods to develop brown spots or gray mold growing on leaves, stems, or pods.

Fungus

A fungus called Alternaria alternata can also cause brown spots on green beans. This fungus is found in many different environments and can be difficult to control.

Alternaria alternata fungus has been causing an increase in the number of snap bean infections recently. Fresh market snap bean growers may suffer significant damages as a result of infections.

Insects

Certain insects such as beetles can damage green bean pods, causing them to develop brown spots.

Mechanical injury

Mechanical injuries occur when green bean pods are damaged by machinery, tools, or other objects.

When do green beans get brown spots?

The time of year that green beans get brown spots can vary depending on the cause.

Bacteria usually causes brown spots to develop shortly after the beans are harvested.

The fungus can cause brown spots to develop at any stage of growth but is more common in older beans.

Insect damage typically occurs when the green bean pods are still young and tender.

Mechanical injuries usually occur during harvesting or processing.

What are the black spots on green beans?

The black pod spot on green beans is typically caused by a fungus called Alternaria alternata. This fungus can cause the pods to develop brown spots on beans as well.

How do you know if green beans have gone bad?

If the green beans have gone bad, they will typically smell the sour odor or rotten. The pods of the bad beans will also be wilted and slimy.

Are Brown Spots on My Green Beans OK?

The answer to this question depends on the cause of the brown spots.

Bacteria can cause food poisoning if the beans are eaten. You should avoid eating green beans with brown spots caused by bacteria.

The fungus can cause the pods to develop brown spots and should be avoided if possible. However, if you do eat them then there is no need for concern as it does not affect your health negatively in any way. 

Insects sometimes damage green bean pods, which may result in brown spots. If you do not see any insects on the green bean pods then it is safe to eat them and there should be no need for concern. 

Mechanical injuries usually cause cosmetic damage only but if you are unsure about whether or not they are safe to eat, then discard them immediately just to be on the safe side.

So, are brown spots on green beans safe to eat? The answer depends on the cause of the brown spots, but in most cases, they are safe to consume. It’s just that you are not getting a pristine bean experience.

However, if you are unsure about whether or not they are safe to eat then it is best to discard them just to be on the safe side.

Can you eat green beans with rust spots?

The sign of rust spots on green beans is typically caused by a fungal disease called Puccinia coronata. As the rusty pod fleck progresses, wounds deepen into the bean thus creating an opening for other pathogens to enter. 

It would be in your best interest not to eat them.

How do you treat rust on green beans?

There is no specific treatment for bean rust. However, you can try to remove the fungus by spraying the infected plants with a fungicide.

You can also try to remove the spots by cutting them off the beans and destroying them. 

To avoid rust from spreading, clear away all litter in between bean plants. Replant the area with resistant varieties.

It’s also important to avoid splashing water onto the infected leaves, as this may aid in the spread of rust to other green bean plant leaves.
