GB/T 28082-2011

This standard specifies the methods for detecting and identifying two fungal pathogens, Ophiostoma novo-ulmi and Ophiostoma ulmi, which cause Dutch elm disease. It is applied in plant quarantine and forestry contexts, particularly for the inspection of imported elm wood, seedlings, and other plant materials to prevent the introduction and spread of these destructive pathogens. The standard provides technical procedures for isolation, morphological observation, and molecular identification to ensure accurate diagnosis in laboratory testing.
