Summary: This standard specifies the seed borne pathogenic fungi, bacteria, viruses (including classes virus) and nematodes such as quarantine and identification of pathogenic microorganisms procedures and general method. This standard applies to the concept of true botanical seeds and propagating material as the fruit (eg: caryopsis, achenes, stone fruit, nuts, etc.), does not apply to plant vegetative organs roots, tubers, corms scales, or underground stems, and tender other agricultural branches and sticks absorb the concept of "seed", and artificial, artificial seeds. Through chemical or physical treatment seeds (such as seed coating treatment) can refer to this standard.
