I have found termites eating at the base of the Rhubarb stock. How can I kill them and not hurt the plant?

I doubt what you're seeing is termites. Sounds more like rhubarb curculio, which burrow in from top down and commonly affect these plants. Here is more info: http://www.entomology.cornell.edu/cals/entomology/extension/idl/upload/Rhubarb-Curculio.pdf
