Pepino mosaic virus on tomatoes update
Given the highly transmissible nature of the Pepino Mosaic Virus (PepMV), industry and MPI have agreed that eradication is not possible. We are now looking at long term management options. Aspects being considered include:
- Supporting the implementation of farm biosecurity measures (greenhouse hygiene).
- Reducing the chances of spread via vectors such as crates.
- Further surveillance to determine the distribution of the virus, and research to understand the impact.
- Exploring the option of using a PepMV “vaccine” to minimise crop damage.
In the meantime it is important that all tomato growers:
- Have good biosecurity cleanliness measures at all stages of crop production. See the TomatoesNZ glasshouse hygiene poster for more information on this.
- If possible, assign workers their own PPE, tools, carts etc and restrict these to single glasshouses or glasshouse sections/compartments.
- Restrict access to your crop – do not allow visitors.
- Keep a close eye on your crop and familiarise yourself with the virus symptoms. Information on the symptoms is available from us, including a poster on the virus.
- If you think you’ve found signs of PepMV, immediately contact Biosecurity New Zealand through its freephone: 0800 80 99 66.
Energy efficiency articles
Last year we arranged for greenhouse specialist, Elly Nederhoff, to update a series of energy efficiency articles for greenhouse growers that she originally developed during a project called ‘Improving Energy Efficiency in Greenhouse Vegetable Production’.
There are now ten updated articles in the series published monthly in NZ Grower from October 2020. These are also available to download here.
The articles are titled:
- Energy efficiency in greenhouses
- Greenhouse climate physics
- Humidity control
- Energy wise humidity control
- Plant empowerment
- Humidity control in GPE approach
- Temperature effects on plants
- Light balance
- Greenhouse temperature
- Climate Control
Growers have told us that they have found these articles helpful and informative, so we think it will be worthwhile adding a few more articles on this subject. We are also looking at putting together an e-book grouping the topics so it is easy to read and reference back to. If there are other areas you would like to see in this series please let us know.
