Japanese eggplant problems
I have 2 Japanese eggplants. One is being destroyed by beetles, all the leaves are eaten. The other has no beetles but the leaves have a rusty powdery look and they are sticky. They are right beside one another yet different problems. They have been bearing for the last month but seems to be slowing down. What can be used to get rid of the leaf problem. I'm an organic gardener and don't want to use anything toxic.

The most common beetle pest of eggplant are Flea Beetles. A pesticide containing Spinosad can be used in organic gardens.
A sticky residue is often created by whiteflies. Insecticidal sprays can be used to organically control whiteflies.
Following is a link to a fact sheet from the University of California with information about pests and diseases of eggplant. Within the document are links to each pest and each disease which will provide additional information including control options: http://ipm.ucanr.edu/PMG/r211301411.html
