Growers advised to remain vigilant
Victorian horticulturists are being urged to implement best-practice biosecurity measures following outbreaks of Tomato Potato Psyllid (TPP) in Western Australia.
Agriculture Victoria chief plant health officer Dr Gabrielle Vivian-Smith said there had been no confirmed reports of TPP in Victoria, but the state had 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 was a small sap-sucking, winged insect, which resembled a tiny cicada (3 mm long) and caused 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,’’ she said.
TPP can also transmit a bacterium, which 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.
