Last year we had okra in our garden that got 7 feet tall and produced constantly. This year it has gotten about 3 feet and a stalk on the end began to turn yellow, even the pod, and then began to die slowly and then it moved to the next stalk and then the next one....it's on about four stalks now with the first one being completely leafless! I don't see any unusal bugs or spots. A couple of brown spots but nothing much. I pulled one up and examined the root and it looks healthy. Any ideas?

Okra is pretty bulletproof, but every so often I have problems with Southern Blight.

Quoting:
SOUTHERN BLIGHT (Sclerotium rolfsii). Southern blight occurs during warm and humid weather and has the potential to explode in the field centers, often as is this is the least-scouted area. The plants exhibit a progressive wilt as the fungus infects the roots and lower stem. A coarse white fungal mat can often be observed at the soil line. It can be controlled with a basal spray of azoxystrobin, but the fungi produces sclerotia which may resist degradation for many years in the field. Some growers rotate with grass crops such as sorghum or sudangrass, which are not fungal hosts, to alleviate the pressure from this fungus as well as deep plow the resting structures (3,20).
and nematodes.
Quoting:
Nematodes are microscopic roundworms present in the soil which feed on plant roots and damage the tissue. Okra is very susceptible to both root-knot and sting nematodes, as well as reniform nematode. In south Florida, water and soil conditions lead to restrictions on nematicides that can be applied. As already mentioned, okra is planted as a secondary crop following a primary crop which has generally received some type of nematicidal treatment. For those growers attempting to manage nematodes just prior to seeding (about 20 percent), dichloropropene is the only chemical option, or they avoid nematode-infested cropland (4,23).

Thanks for your input. I'll check the okra more closely for some more of these symptoms.
