So, we are here to discuss the top 4 blue lake pole beans issues along with treatments-
Reason 1: Yellow Leaves
The first thing you’ll notice on your plant is yellow leaves. Your plants having yellow leaves is a common issue for bean plants. In most cases, the culprit of this problem is the soil or the temperature.
But there are other reasons too. For instance, check if there is any sort of bacteria or virus-like bean mosaic virus.
Usually, these diseases transmit through insects like aphids. These result in yellow leaves. Your bean leaves might have holes in them too if this is the cause.
Generally in the winter season, the plant’s leaves go dry and turn yellow. This can be another reason as well. For bean plants, winter is an ideal time to spread diseases very quickly. Thus, leaves turn yellow and fall off.
If too much heat is causing the yellow, transfer your plant to a cooler place. Water the plant till it’s hydrated again.

Lastly, the reason behind the yellow leaves can also be a fungal disease. In that case, cut the affected leaf parts first and discard them. Then use a good quality fungicide to stop the disease from spreading even more.
Here are some top-quality fungicides to use-
Reason 2: Shriveled Leaves
Mosaic virus or aphids can be the reason for your shriveled leaves. But cucurbit leaf crumple virus can be responsible too. It is one sort of whitefly that causes leaf curl disease.
If the reason is insects, just use a good insecticide. However, controlling the mosaic virus isn’t easy.
You’ll have to prune the infected parts of the leaf immediately. Then burn them. But you can’t cure the plant. Therefore, it’s best to get rid of the plant afterward.

Reason 3: Malformed Bean Leaves
Herbicide is quite popular among gardeners. Herbicide has both pros and cons, which can affect your plant’s well-being. For example, using too much herbicide can also cause malformed bean leaves.
Products similar to horse manure or mulching with grass clipping can harm your leaves. These help to form aphids in your plant and end up with malformed leaves.
Firstly, minimize the use of any herbicide. Or totally change the brand to an effective yet less harmful one.
Secondly, the use of soapy water is another most effective way to protect your leaves. Spray the soap water liquid all over your bean plant. Then insects like aphids will be gone.
Removing the mulching part is quite helpful too. The moment you see some growth of malformed leaves, just take off the mulch thing. Thus, your leaves will recover quickly.
But if nothing works, pluck out the whole plant and wait till the summer. As summer is the ideal time to grow bean plants.

Firstly, identify the reason behind drying up leaves. If it’s not related to any insects or bugs, change the plant’s location. Place them into a cooler place and water them regularly.
But when it’s the insects, apply insecticides to demolish them.
