Scope

GB/T 44611-2024 is the English-translated version of 栽培介质有害生物检测规程.

GB/T 44611-2024 is the Chinese code of practice for detecting pests in growing media. Peat, coir, bark and rock wool move internationally in enormous volume, often accompanying live plants, and they are one of the least watched pathways for quarantine organisms: a medium is bulk material that looks inert, but it can carry nematodes, soil-borne pathogens, insect eggs, snails and viable weed seed. The standard sets out the basic information to be established about the medium, the testing procedure, the detection targets and the basis for testing, the on-site inspection, and the laboratory testing, which is given separately for insects and molluscs, nematodes, plant pathogenic fungi, plant pathogenic bacteria and weeds, followed by the test result report, with annexes on the flotation separation and modified funnel extraction methods. It takes effect on 1 April 2025.
