Green Bean Issues
Some of my green bean plants are beginning to drop leaves, and some of the green beans are turning white. Produced well first part of the summer, but with the heat here in SW Oklahoma, things are beginning to change. I have read that this could be rust, or pythium blight, or powdery mildew. My questions:
Are fungicides safe for consumption?
Does this affect the soil for fall or later planting?
Can I simply just pull out all plants and it will take care of the problem?
Any help with this would be appreciated. I'm new to planting green beans. Thanks, Denise
