Abstract

Cross inoculations from mosaic cucurbits to non-cucurbitaceous hosts, according to published records, have been unsuccessful except in a few cases. Doolittle obtained infection by aphis inoculation from mosaic cucumbers to Martynia louisiana, while Jagger obtained infection on Lobelia crinus var. Gracilis and Helianthus debilis. Preliminary experiments by the writer show that cucurbit mosaic can be transmitted to Nepeta cataria by the insertion of crushed mosaic leaf tissue of mosaic gourd into the stems of Catnip. Typical mosaic symptoms appeared on the tips of the leaves of the catnip in about three weeks, and after six weeks practically every leaf showed the mosaic. Mosaic of catnip has not been observed in the field by the writer, but with the ease of obtaining infection and chances of insect inoculation, this perennial host may be a source of early infection to cucumbers in the field.
