Pole bean issue #878254

Asked July 22, 2024, 12:49 PM EDT

I returned from vacation to find my pole beans looking like the photos below. Is it a mosaic virus? What can I do?

Expert Response

Thank you for your question.

You are right.  It seems that your pole beans have mosaic disease.   The virus is spread by aphids and apparently by infected seeds.

Unfortunately, there is no cure, and it is recommended that you remove and destroy the infected plants. Do not put in the compost.  Disinfect all gardening tools. 

In the future, purchase disease resistant strains and rotate your crops to different beds.

I am so sorry about your beans.  It is just awful to have to pull plants you have nurtured.

That is a bummer, was hoping it was not that. Can it come from compost? I put fresh garden compost purchased from a nursery on the garden this year?
Thanks for the prompt response. Your help is greatly appreciated.

Hi again.  I didn't read anything about the virus often coming from compost, but of course it is possible.  The infected plants shouldn't be composted because the virus could survive there.  Usually, nursery compost heats up very high - higher than home compost bins - so I'd guess that would kill it.

What surprised me was that the seeds themselves can carry the infection, and it was and may still be a problem in the industry!

Anyway, I agree - huge bummer!
