New control measures for pyriform scale
Pyriform scale is an exotic plant pest that could attack a range of horticultural, nursery and native plants including avocado, mango, citrus, banana, eucalyptus and hibiscus. Pyriform scale was found in Perth in May 2015 and as a result NSW has introduced emergency import conditions. These emergency legislative measures apply to NSW businesses and private importers bringing in stock from Western Australia. Stock from infested areas requires treatment and inspection before it is transported to NSW and must be accompanied by a current Plant Health Certificate by the Western Australian Government.
What is pyriform scale
Pyriform scale (Protopulvinaria pyriformis) is an exotic plant pest which is a serious threat to a range of host plants including avocado, mango, citrus, banana, passionfruit, pomegranate, papaya, eucalyptus, hibiscus, gardenia, ivy, myrtle, laurels, paperplant and frangipani. Pyriform scale has a pear shaped body surrounded by a waxy fringe and a protective coating that gives it a raised scab like appearance on the underside of leaves. This pest causes leaf drop, reduced vigour and reduced fruit production in infested plants. Infestation is spread through the movement of infested host plants including fruiting and ornamental varieties.
Pyriform scale was detected in Perth in May 2015. The scale has not been detected outside the Perth metropolitan area. To protect NSW industries, native, fruiting and ornamental plants, NSW will introduce emergency import conditions. This implementation will occur in mid-December in line with other states and territories.
New legislation for controlled movement of host nursery stock
Emergency legislative measures require treatment and inspection of host nursery stock grown in infested areas. Treatment and inspection requirements will be certified by means of a Plant Health Certificate for movement into NSW.
Implications for NSW nursery stock importers
NSW businesses and private importers will need to ensure that host nursery stock sourced from Western Australia is consigned with a current Plant Health Certificate issued by the Western Australian Government.
