Yellow Spots On Beans

Question

I read your article on beans and happen to have a small dragon bean bush that’s about 8 weeks old. I live in arkansas zone 7.ive noticed small yellow spots with stunted growth. I’ve grown this plant in the past and expect it to be much bigger by now. All the tomato’s in my raised bed seem to be doing fine except my bush. Any suggestions? I thought over watered. From all the rain. But I’m unsure. Lower leaves are going yellow and falling off. Sorry about the night pics. I just got off work. The leaves are still opening during the day thanks for any help.

I can't really get a good look at the leaves, but I do see the healthy tomato plant. Excessive water may have weakened the bean enough for it to contract golden mosaic virus through flies that feed on bean plants. This will cause you leaves to turn bright yellow and start to deform, though the symptoms can range from plant to plant. It will quickly die off after. This is not treatable, unfortunately. You will have to plant any legume in a different area. It will only infect legumes, like beans, peas, soy beans, lima beans, or any other.

Unfortunately, planting in a new area will be the only way to manage, but your other crops should be just fine. To confirm, or get a thorough diagnosis, I would test your soils, or have them tested by the closest extension service to you.
