In Tasmania, Australia, surveillance programs for the tomato potato psyllid (TPP) are being ramped up as growers try to delay any incursion of the pest for as long as possible.

Raylea Rowbottom, a researcher of the Tasmanian Institute of Agriculture says it's inevitable that the potato psyllid, a destructive insect that has threatened tomato and potato crops in Western Australia will make it to the east coast.

JR Simplot has applied at FSANZ for approval to export genetically modified potato products into Australia and New Zealand. Unclear is what type of products this is about, but unprocessed potatoes can not be imported.

Plant Biosecurity CRC scientists have identified stable regions in the genome of Candidatus Liberibacter solanacearum (CLso), which causes the serious disease Zebra Chip in potato and tomato crops. This research will provide new diagnostics that will significantly reduce uncertainty in biosecurity assessments.

Seed potato growers on Kangaroo Island - an island off the mainland of South Australia - are successfully adopting a new strategy to manage the aphids and thrips pestering their crops, taking on expert advice from agronomists and entomologists to adopt integrated pest management for these insect pests.

Alan Parker looked out onto the farm business he had spent his entire life establishing. The West Australian seed potato grower will know in the next six weeks whether his lifelong career will continue.

Potato Psyllids, a destructive plant pest found for the first time in Australia in February cannot be eradicated, so the industry will seek to manage it, rather than destroy it, according to The Department of Food and Agriculture of West Australia.

In New Zealand, a team of Lincoln University researchers is impressed with the results from a trial of a mesh cover that is used to protect potato crops from insect pests.

Potato producers in south-west Western Australia say the detection of the potato psyllid (Bactericera cockerelli) is a "serious blow" to their industry. The detection of the psyllid may put national and international exports in jeopardy.

Potatoes New Zealand became the 14th partner organisation to join the Government Industry Agreement for Biosecurity Readiness and Response.

With pesticide resistance rising in species of aphids which feed on potatoes and spread viruses, one of the best control options for growers battling these pests may be found in nature, free of charge: parasitic wasps.

The Environmental Protection Authority (EPA) of New Zealand has approved a type of parasitic wasp as a biological control agent to combat the tomato potato psyllid (a plant louse), which attacks tomatoes, potatoes, capsicums and tamarillos in the country.

Australian Researchers are working closely with the country's potato industry to investigate the potential for the highly destructive Tomato-potato psyllid (TPP) to enter Australia using natural pathways.

Australian potato growers are being reminded to prepare for late blight, a potato disease that strikes when conditions are humid, stagnant and warm.

Potatoes New Zealand chief executive Champak Mehta says the industry now has the potato psyllid well under control thanks to the knowledge gained through research.

South Australian potato growers will have the opportunity to be updated on the latest research and development (R&D) including managing soil pathogens, pests and diseases at a special workshop to be held by AUSVEG in Murray Bridge next week.

Potatoes New Zealand Inc. has won funding from the Ministry of Primary Industries for a major research project aimed at improving crop yield, more specifically, the impact of crop rotations on soil borne diseases and soil quality.

During a quarantine survey on Norfolk Island, a small island between New Zealand and Australia, both the tomato-potato psyllid (Bactericera cockerelli) as well as the zebra chip causing bacterium Ca. Liberibacter solanacearum (Lso) have been detected.
