Some sort of small black bugs have infested our okra plants. They congregate on buds, blooms and the underside of leaves. These are destructive little things, as you can see by the leaf (or what's left of it) pictured below. I gave them a good blast with the water hose this morning and, after quite a bit of effort, washed most of them away. If they come back I'll have to take more drastic measures.
