My beans are not looking so good. Looks like they are suffering from some sort of blight. I treated them as I do my tomato plants when they show signs of Early Blight. I removed the diseased leaves and threw them far away.
Here are some Quick Facts from the web site: http://www.ext.colostate.edu/PUBS/crops/02913.html
- Halo blight and bacterial brown spot are favored by cool to moderate temperatures, high moisture and plant wounds before flowering.
- Common bacterial blight is favored by moderate to warm temperatures, high moisture and plant wounds during and after flowering.
- The pathogens can survive in infected debris and are seed-borne.
- Disease management recommendations rely upon crop rotation, sanitation, planting treated certified seed, varietal selection, stress and wound avoidance, and proper pesticide scheduling.
So, removing the diseased leaves may not be enough. These beans are in the same bed I had green beans in last year. It might be best to remove all the bean plants and try something else in that space this summer. But there's such a nice support system built into that bed! I guess best gardening practices will have to take priority over reusing existing garden structures.
