Tomato bio alert
VICTORIAN horticulturists are being urged to implement best practice biosecurity measures following outbreaks of Tomato Potato Psyllid (TPP) in Western Australia.
Chief plant health officer Dr Gabrielle Vivian-Smith said there have been no confirmed reports of TPP in Victoria.
Victoria has imposed restrictions on the importation of any risk material from Western Australia as a precaution.
The restrictions extend to plant or plant product belonging to the family Convolvulaceae or the family Solanaceae.
These families include plants such as sweet potatoes, capsicums, tomatoes, eggplants, potatoes, tamarillos and chillies.
Dr Vivian-Smith said TPP is a small sap-sucking, winged insect, which resembles a tiny cicada (3mm long).
TPP causes yellowing of the leaves, wilting, misshapen fruit and reduced crop yield.
A noticeable sign is the presence of small insects jumping from the foliage when disturbed.
Adult psyllids are sometimes called jumping plant lice as they readily jump and fly when disturbed.
TPP can also transmit a bacterium called CLso (Candidatus Liberibacter solanacearum) that is associated with the zebra chip disease in potato.
The bacterium can also cause stunting, stem death, yellowed leaves and yield losses in capsicums, chillies and tomatoes.
The bacterium does not pose a risk to human health and it has not been detected in Victoria.
Growers are advised to remain vigilant and to regularly check their crops.
