Methyl bromide alternative to be assessed by officials
28 August 2017
Ethanedinitrile (EDN) has been extensively evaluated by STIMBR as a phytosanitary treatment for export logs and timber products. It has showed considerable promise controlling the three forest pests of most concern to New Zealand's trading partners.
An application for registration was lodged with the Environmental Protection Authority (EPA) in July 2017. The EPA has asked for additional information to provide clarification of some issues. It is expected that the EPA will ask for public submissions in September, closing in October/November, with a registration decision likely early in 2018.
The following documents, which were presented at meetings in August 2017, provide additional information about EDN, its manufacturer Draslovka, and the extent of biosecurity risks faced by New Zealand's export log and timber industry.
Mark Greenwood's biosecurity contribution acknowledged
6 June 2016
Mark Greenwood of Te Puke was awarded the New Zealand honour of Officer of the New Zealand Order of Merit in the 2016 Queen's Birthday Honours. Mark was a founder of STIMBR.
Mark Greenwood has developed a highly respected reputation in the international biosecurity community as an expert in fumigation and helping to position New Zealand as a global leader in this field.
Mark Greenwood is the owner and Managing Director of Genera Limited, 100% New Zealand family-owned business which provides biosecurity treatments. Genera was the first company to offer fumigant recapture in New Zealand and also pioneered the world’s first use of in-transit fumigation of log ships using phosphine gas, which has saved thousands of tonnes of methyl bromide from being released into the atmosphere. He has overseen the introduction of several other alternative forms of biosecurity treatment such as cylinderised phosphine and chemical-free heat treatment. He instigated the formation of STIMBR (Stakeholders in Methyl Bromide Reduction), an action group set up to research alternatives to methyl bromide. He is also the New Zealand representative of the International Maritime Fumigation Organisation. Through Genera Mark Greenwood sponsors pest control for 10 hectares of Stewart Island.
Log export statistics to June 2015
15 January 2016
New Zealand exported 16 million cubic metres of logs in the year to June 2015. The majority of these logs (11.4 million cubic metres) were exported to China. The following are breakdown of types of phytosanitary action of the 13 million cubic metres (mainly China and India) that required treatment:

Methyl bromide alternatives literature review
20 December 2015
In 2014 STIMBR commissioned a comprehensive literature review to determine whether any fumigants, or disinfestation strategies, methods or techniques presented viable alternatives to methyl bromide fumigation for New Zealand log exports.
The viability of alternatives focused on considerations of currency in the literature, economic and regulatory feasibility, environmental and human health concerns, efficacy against target pests, utility for log exports, and commercial application aspects based on current and historical literature.
The primary goal of the literature review was to find two fumigants that could be recommended as viable alternatives for further research under the Ministry for Business, Innovation, and Employment (MBIE) research programme, “Protecting Market Access for Wood Exports”.
