Scope

GB/T 36779-2018 is the English-translated version of 芹菜枯萎病菌检疫鉴定方法.

GB/T 36779-2018 is the Chinese national method for detecting and identifying Fusarium oxysporum f. sp. apii, the fungus that causes Fusarium wilt of celery.

It gives the basic information on the pathogen - its scientific name, synonyms and taxonomic position - and bases identification on disease symptoms, colony culture characteristics, host range, molecular biological characteristics and the results of a pathogenicity test.

It lists the instruments, appliances and main reagents required, from a PCR instrument, light incubator, microscopes and gel imaging system to inoculation needles and petri dishes, with sampling done according to SN/T 2122.

It applies to celery seeds, seedlings and plant residues that may carry the pathogen, and is used by plant quarantine laboratories. It was issued on 17 September 2018 and has applied since 1 April 2019.
