Question Our green bean plants are beautiful except for the top few leaves, which are wilting and curling up. Is it a pest or a disease and what can we do? We live in NM near Albuquerque. We water every other day and mulch so I don't think lack of water is the problem.
Answer Dear Cathy:
I suspect your green beans may have mosaic virus disease. This disease is often carried in the seed used for planting. Viruses are difficult to control and a challenge to isolate their origin. Two fungicidal organic type products may offer some moderate control over the disease:
1. Bordeaux Mix
2. Safer Garden Fungicide
Or, use chemical control such as Daconil.
Listed below is a site that can provide you with more details on the management of viruses in the garden:
