New article types for New Zealand Plant Protection

Recently, New Zealand Plant Protection introduced new article types. This change is in line with the separation of the journal from the Society’s conference that was formalised at the 2019 AGM. The purpose of additional article types is to encourage a broader range of submissions from across the diversity of plant protection practitioners in New Zealand. Having a variety of article types conforms to the style of most national and international science journals and will hopefully stimulate more interest in the journal. In addition to the standard Research Articles (original research in the traditional format, no word limit) and Literature Reviews (comprehensive review of published literature plus an analysis of findings and summary of knowledge gaps), the Journal will now consider:

Research Notes: New science, succinctly presented (<2500 words), e.g. preliminary findings, small experiments, improved methodologies.

Applied Practices papers: Comparisons of methods or technologies applied to pest management, biosecurity surveillance, or pest eradication, and

Perspectives: Qualitative and balanced overview of a topic in <3000 words supported by published literature.

Go to the Journal’s website for further information on the scope and requirements for each article type. To assist authors, article templates are also available for each article type and can be downloaded from the website.

Traditionally, the Society’s conference is proceeded by a symposium on a specialised topic. This often resulted in a published symposium proceedings. It’s my hope, that in the future, symposium organisers will take on the role of guest editors, and produce special issues of the journal. Special issues are not limited to the Society’s symposia. In fact, a special issue is currently in progress, based on the 4th International Workshop on European canker, guest edited by Reiny Scheper and Monika Walter. If you are organising a conference or symposium on a plant protection related topic, and interested in producing a special of New Zealand Plant Protection, please contact the editor (Ruth Falshaw). The success of the journal depends on article submissions by the membership. As mentioned in previous communications, submissions can be made at any time. I hope that members of the Society will consider New Zealand Plant Protection as venue to publish their research.

Mike Cripps, President

From the President

The year 2020 is nearly gone, and I think most of us will be happy to bid it farewell. The Covid-19 pandemic hit the world hard in early 2020, and continues to affect the way we work and socialise today. The nationwide level-4 lockdown that came into effect on 25 March also coincided with the date of the first NZPPS Executive Committee meeting of the year. Only a couple weeks prior to the meeting the Committee was discussing travel arrangements. How quickly things changed! It was clear that 2020 was not going to be an ordinary year. The Executive had to decide whether or not to proceed with planning the August conference. At the time, it was hard to know what to do. After all, the August conference was still more than four months away. After some debate, the Committee thought it best to postpone the conference until the following year. This decision proved to be the right one.

With many parts of the world currently dealing with second or third waves of the virus, it is clear that New Zealand has handled the Covid-19 crisis better than most countries, and like me, I’m sure that most of you are happy and proud of the collective response in New Zealand that quashed the virus. Undoubtedly, there are many learnings from the challenges of 2020, both personal and professional, and possibly even for plant protection research in New Zealand. Those of us in the biosecurity sphere have always known that “going hard, and going early” is the only way to deal with incursion threats to our primary production sectors. However, knowing what to do is only the first step – getting the community, or indeed the entire country, behind the initiative is the key to success. It wasn’t government edicts per se that saved the day against Covid-19 in New Zealand, but rather the collective response of the team of 5 million. Certainly, a lesson from New Zealand’s success against Covid-19 is that effective communication is key to achieving public support. New Zealand has received international praise for its response to Covid-19, and rightly so. But New Zealand also has many great plant protection stories that need to be told. One such story is the pea weevil eradication from the Wairarapa, reported on in the June 2020 newsletter. This is an excellent example of a government programme that was effective because of community support, achieved through good communication about the actions that were needed.

While unfortunately overshadowed by the pandemic, the year 2020 was also declared by the United Nations as the International Year of Plant Health (IYPH). The goal of this initiative was to raise awareness about the importance of plant protection for achieving the UN Sustainable Development Goals to help end hunger, reduce poverty, protect the environment, and boost economic development. As members of the New Zealand Plant Protection Society, we understand that these are desired outcomes of plant protection research and extension activities. We also need to help other people understand this. The IYPH serves to remind us all that plants are essential for life, and everyone has a role in protecting them.

The presidential reins were passed to me during the 2020 AGM held at Lincoln University. The AGM was online with some local Lincoln members attending in person. It ended with a quiet afternoon tea, before going back to work. I couldn’t help thinking that typically the handover of the presidency role happens at the annual conference dinner, with wine, food, and music. It’s unfortunate that we couldn’t meet for a conference this year, but I look forward to seeing you all at the 73rd Conference of the New Zealand Plant Protection Society in Napier from 10-12 August 2021.

On behalf of the Executive, I wish the members of the Society a Merry Christmas and a happy New Year.

Mike Cripps

2020 NZPPS Annual General Meeting

The 2020 NZPPS Annual General Meeting was held on 2 September at Lincoln University and simultaneously via Zoom. Fourteen members attended in person and a further 17 members participated online. This was the first time that the Society has held an AGM in such a format and it worked well. Online attendees typed their comments online and these were read out by the President. The President, Treasurer, Editor and Web-Editor each presented a report.

All these reports are available online at: https://nzpps.org/events/annual-general-meeting-2020/  The meeting lasted 1 hour and was followed by afternoon tea for attendees at Lincoln.

The following members stood for election as Officers of the Society and all were returned unopposed:

President:         Mike Cripps
Vice President: Hayley Ridgway
Treasurer:         Jason Smith
Editor:               Ruth Falshaw
Secretary:         Jenny Taylor
Committee:       Rebecca Fisher; Joy Tyson; Dale Neill; Claire Mills; Vanessa Cotterill; and Soonie Chng

Eirian Jones is the Immediate Past President.

Gareth Hill has been co-opted onto the Committee as the Web Editor and the Treasurer recommended that the current auditors Owen McLeod & Co. be used again in 2021.

The Executive Committee extends a warm welcome to new members Rebecca Fisher and Soonie Chng and is pleased to retain the expertise of existing members.

Rebecca has been a member of the NZPPS since 2006 and has been an active member of the Society – contributing to forums and presenting at conference. Rebecca is the Crop Protection Manager at Market Access Solutionz, based in Wellington.  Her expertise lies in the area of crop protection regulation.  Rebecca works with grower groups on crop protection strategy development, registration of new products and EPA reassessments. Rebecca is also the Executive Manager for NZ Citrus Growers and serves as a Director on the board of AGCARM Inc. (Agricultural Compounds and Animal Remedy Manufacturers). Her strengths lie in engagement of a wide range of stakeholders across plant protection industries – from growers to government regulators and would bring a fresh and dynamic perspective to the committee. Rebecca has sound governance experience and an obvious passion for plant protection.

Soonie is a plant pathologist at the New Zealand Institute for Plant and Food Research Limited. Soonie’s research expertise is in arable and vegetable pathology, with a primary focus on the management of both airborne and soil-borne diseases, such as cereal rusts and root rots. She works closely with the New Zealand arable and vegetable cropping industries and collaborates with international peers on management of major crop diseases. Soonie was a committee member for New Zealand Women in Science in 2018, hence she understand the responsibilities and the dynamic energy required as a NZPPS committee member and she is keen to contribute towards a society so relevant to her field of interest.

What’s in a name?

Did you know that our very own journal editor, Ruth Falshaw, has had a species of seaweed named after her? 

The seaweed was previously known as Gigartina ‘sp. 164’ and occurs on exposed, rocky coasts in the south and west of the South Island and other southern islands of New Zealand. 

Last year, D’Archino et al.1 named this species Gigartina falshawiae: “In honour of Ruth Falshaw for her contribution to the study of the chemistry of macroalgae and particularly New Zealand Gigartinaceae.” Ruth says she is very humbled to receive such an honour. 

1 D’Archino R, Nelson WA, Sutherland JE 2019. Unnamed for over 30 years: Gigartina falshawiae sp. nov. (Gigartinaceae, Rhodophyta) and its confusion with Iridaea tuberculosa in New Zealand. Phycologia https://doi.org/10.1080/00318884.2019.1667187
