January 2014. Maize from Nghe An Province, Vietnam with stripe sent for identification. The question asked was whether it could be virus or phytoplasma? And where to send specimens for analysis.

It was suggested that the Directory y of Diagnostic Services that has been published for Vietnam should be consulted for info on diagnostic labs. The document can be accessed in the Links to useful information and tools for Vietnam at the bottom of this page: http://www.plantwise.org/knowledgebank/CountryHome/Vietnam/.

There was a suggestion that the images were showing early stages of Pantoea stewartii. Samples were examine in great detail by CABI Plantwise, but although there was a suspicion of Stewart’s disease, no evidence for its presence was found.
