Crinkled green bean leaves

Asked July 1, 2018, 9:01 PM EDT

What is happening to our beans? This variety is Fortex, a pole bean. We are seeing some leaves such as the crinkled leaf on the right, and the beans seem to lack their usual vigor this year. Have not seen this before. It doesn’t quite look like the mosaic virus pics that I see, though somewhat similar. Is there any way to treat it?

Unless you have used a herbicide and it damaged the foliage then I am inclined to think that it is the bean common mosaic virus. They are an heirloom bean that is susceptible to the virus. If it is the virus there is nothing you can do to cure it. Here is a little more info about it. https://plantix.net/plant-disease/en/200004/bean-common-mosaic-virus/ . http://vegetablemdonline.ppath.cornell.edu/factsheets/Virus_Beans.htm . You can send a sample to the plant disease clinic if you like. https://pdc.umn.edu/
