New – Pistachio Irrigation Research Paper by Louise Ferguson et. al.

Sustainability of pistachio production (Pistacia vera L.) under supplemental
irrigation in a Mediterranean climate.   The paper looks at the effects of supplemental micro-irrigation in a commercial rainfed orchard.  Irrigating with 10–15% of estimated full evaporative demand significantly increased average annual productivity by increasing yield in the on-crop year of this alternate bearing species. Irrigation increased yield by 30%, resulting in 1600 kg of in-shell product per ha.  You can download and read the research paper here:  Marinoetal2018

Tenth Edition Of the National Plant Biosecurity Status Report by PHA now available.


The tenth edition of the National Plant Biosecurity Status Report has been released this week by Plant Health Australia.  The report is a guide to how Australia protects itself against exotic plant pests and diseases and reveals the tremendous effort being made across the country to sustain our plant industries, unique ecosystems and standards of living.

This year the report displays the system through the three layers of protection: pre-border, at the border and post-border, with examples of how the this works in specific circumstances. It details the efforts being made by everyone involved in plant biosecurity, be they the Australian or state governments, industries, research agencies and the community.

VoH welcomes Federal Budget’s support of export markets and biosecurity

The continued efforts made by Voice of Horticulture (VoH) in lobbying the Federal Government in terms of a policy and budget focus on biosecurity and exports, has seen fruition in this week’s 2018/19 Budget.
Chair, Tania Chapman welcomed the announcement of five key points relating to biosecurity, the Australian Pesticides and Veterinary Medicines Authority (APVMA) and export trade assistance and said they would provide invaluable support in improving market access and on gaining new export opportunities.
Ms Chapman said the “real coup” was the announcement of additional funding to represent six Agricultural Trade Counsellors in six new countries, to be included in the United Kingdom, Mexico, Japan, India, Chile and Russia, now extending the total number of Agricultural Trade Counsellors to 22.

Pistachio Seasonal Reminders.  Summer and Pre-Harvest 2017/2018.  An update by Ben Thomas.

Welcome to 2018! Hopefully, you all had a break during the Festive period and are refreshed and ready for the upcoming harvest period.
We are now in the nut fill period of the pistachio production cycle which is a critical phase when the kernel grows and causes the shell to split. Key orchard management issues at this time are irrigation and nutrition. This is also the time to prepare the orchard for harvest, take leaf analysis samples and bud young trees.  Read more here:  SummerPreharvest 2017-2018
