On-Farm Chestnut Biosecurity Planner

Work on the Chestnut Biosecurity Planner has been completed. The document is currently being printed and a hard copy will be posted to each CAI member. The planner is such that you can write notes in each of the sections to assist you in undertaking your own on-farm biosecurity. Use the document also to inform, train and educate your orchard staff.

Victorian chestnut growers will be supported with a range of new materials to manage chestnut blight on their trees.


Chestnuts Australia Inc. has contracted a Chestnut Industry Biosecurity Officer to work as part of the Chestnut Blight team.

Elke Jasper has been engaged and commenced on the 1st December 2020.

Elke has been contracted as the Industry Biosecurity Officer (IBO) to work with the growers and industry to maintain and expand the Chestnut Blight program of locating and destroying any remnants of the disease within Victoria. This can only be done with your help and willingness to learn together to explore new and proven effective biosecurity techniques.

CAI has been working with Agriculture Victoria and preparing a wealth of material for growers, their staff and other support people to undertake a comprehensive survey program.

Some of the material includes:

The newly contracted IBO will deliver copies of all the documents as part of her visits. In addition, the Guide to managing Chestnut Blight and Chestnut Blight surveillance form are available online.

If you need to discuss any matters relating to Chestnut Blight do not hesitate to contact Trevor Ranford on 0417 809 172 or email or email Elke Jasper at

Chestnut Blight – Symptoms – Martin Mebalds – Agriculture Victoria – 16th November 2019

Chestnut blight was detected in the Ovens Valley, Victoria, in September 2010. A national cost-shared eradication response under the EPPRD was agreed by NMG on 25 November 2010, with activities including:

• removal and destruction of host trees (chestnut and oak trees)
• assessment and payment of owner reimbursement costs to eligible growers
• restrictions on the movement of host material, equipment and machinery
• surveillance to demonstrate freedom (during autumn and spring)
• regular surveillance of the area
• regular communication and engagement with industry.

The NMG agreed on 3rd October 2019 based on the technical advice from CCEPP, that eradication of chestnut blight from Australia is not technically feasible or cost effective and the response should enter a Transition to Management Phase.

As of 28th October 2019, chestnut blight has been confirmed on 17 properties in the Ovens Valley region and one property in Fumina, Victoria.

Agriculture Victoria and Chestnuts Australia have since prepared a plan for the orderly transition from eradication under the Emergency Plant Pest Response Deed (EPPRD) to long term management outside the EPPRD. The NMG considered this plan and it was agreed to by all parties on the 20th December 2019. The aim of the revised response plan will be to assist growers to manage the disease into the future.

Agriculture Victoria and Chestnuts Australia will continue to work together to limit the impact of this disease on the chestnut industry.

Chestnut Blight Update – Industry Notice – August 2017

PROPERTY IDENTIFICATION CODES (PIC) Property Identification Codes (PICs) are mandatory for all chestnut groves in Victoria with 20 trees or more. PIC compliance is underway and failure to register for a PIC may see growers subject to penalties under the Act. PICs provide Agriculture Victoria with the ability to respond to outbreaks of exotic pests and diseases quickly and efficiently. This is crucial when chestnut blight is still under an eradication program. Victorian chestnut growers can register for a PIC free of charge by ringing the PIC helpline 1800 678 779 or via searching for ‘PIC’ on the Agriculture Victoria website at:
