Zinnia Problem

July 2004

Diagnosis pending

This problem first appeared the first week of July after a rainy period. The zinnias were cut and placed in water and 24 hours later the cut stems had turned brown and discolored the water. The problem in the field was asymptomatic when the plants were cut. Later, a couple of plants died suddenly. The stems on the cut flowers turned brown, starting towards the middle of the stem. The vascular tissue also turned brown and there was some sliminess. The water or stems did not have the smell that one would expect with a bacterial disease.
