11      Onion Smut and Iris Yellow Spot Tospovirus (IYSV) - Hosts and Vectors

A person must not import, or cause to be imported, any type of Allium spp.1 bulbs, except in accordance with the following:

I.         Allium spp. bulbs for human consumption2 may be imported into Tasmania:

(a)     from any region where Onion Smut (Urocystis cepulae Frost) is not known to occur;

or

(b)     provided that the bulbs are accompanied by a certificate to verify that the crop was inspected by an approved person (Qualified Government Officer with plant pathogen expertise) prior to bulb formation, and again prior to the bulbs being harvested (roots cut), and found free of U. cepulae and that no plants are known to be infected by U. cepulae within a 10km radius of the crop, and that:

(i)       the bulbs are free from storage mould; and

(ii)     they are packed in sound, clean packages with the grower’s name and address on the package, or on a tag inside the packages. This regulation applies to bulbs harvested after December 2008.

II.       Allium spp. bulbs for mother plants (bulbs for propagation) and transplants3 cannot be imported into Tasmania unless:

(a)       they have been certified free of Urocystis cepulae and Iris Yellow Spot Tospovirus (IYSV) by an approved seed production program;

or

(b)       they are accompanied by a certificate to verify that the crop was inspected by an approved person (Qualified Government Officer with plant pathogen expertise) prior to bulb formation and again prior to being harvested and found free of U. cepulae and IYSV; and

(c)       that no plants are known to be infected by U. cepulae or IYSV within a 10km radius of the site where the crop was produced.

III.      Agricultural equipment and other prescribed matter from any region where U. cepulae is known to occur must be accompanied by a certificate signed by an approved person stating that the equipment or other prescribed matter has not been used within 3km of the location of any outbreak of U. cepulae.

Consignments must be accompanied by a Plant Health Certificate.

·         1 Allium spp. includes, but is not limited to, all edible cultivars (or species) of onion, leek, spring onion, shallot, chive and garlic.

·         2 Peeled/processed garlic is exempt from IR11, as are Allium spp. grown within Australia for human consumption.

·         3 Transplants (such as seedling plant trays) of all edible Alliums must comply with the same requirements as that required for ‘bulbs for mother plants’, as specified in Section II of IR11.
