Ad Hoc Tubers
headline bar

These tubers are produced on plants isolated in an insect-controlled greenhouse on benches, in sterilized clay pots containing commercial soilless mix, and originating from in vitro material which tested free of viruses.  However, propagation outside of the isolation of our standard in vitro maintenance does introduce disease-related risks.  We recommend that the most appropriate use of these tubers is destructive testing or one-year field growouts which you are confident would present no risk to your program.  For any other uses, we highly recommend you order the clones you want in the standard in vitro form.

The greenhouse spray program was not done with a food crop in mind, so these tubers themselves are...
