Vineland – Why do the best fruits seem to have the shortest shelf life? It’s a challenge that plagues fresh fruit markets around the world, and has real implications for consumers and fruit growers.
Now, new research from University of Guelph has led to the development of a product that extends the shelf life of fresh fruits by days and even weeks, and it is showing promise in food insecure regions around the world.
“In people and in fruit, skin shrinks with age — it’s part of the life cycle, as the membranes start losing their tightness,” said Jay Subramanian, Professor of Tree Fruit Breeding and Biotechnology at the University of Guelph, who works from the Vineland research station. “Now we know the enzymes responsible for that process can be slowed.”
The secret, according to Subramanian, is in hexanal, a compound that is naturally produced by every plant in the world. His lab has developed a formulation that includes a higher concentration of hexanal to keep fruit fresh for longer.
Subramanian’s research team began experimenting with applying their formula to sweet cherry and peaches in the Niagara region. They found they were able to extend the shelf life of both fruits and spraying the formula directly on the plant prior to harvest worked as well as using it as a dip for newly harvested fruit.

Vineland – Farmers interested in adding a new crop to their production line-up may want to look at okra as an opportunity.
That’s according to researchers at Vineland Research and Innovation Centre (Vineland) who have been working with the crop for the past five years and have some very promising results from two years of field trials with three okra varieties.
“We know okra can be grown commercially in southern Ontario and that yields of 20,000 kg per hectare are possible,” said Vineland research scientist Dr. Viliam Zvalo.
Canada imported over six million kilograms of okra in 2015 – an increase of 43 per cent since 2011 – so the market demand for this new crop, popular especially in South and Southeast Asian cuisine, is there.
Zvalo is particularly excited about three additional varieties Vineland has been able to source from East West Seeds from Thailand. The company is a key player in the okra seed market in countries like India, the Philippines, Malaysia and Thailand where much of the world’s okra is grown.
“We planted some of these varieties in June last year and were amazed by the yield potential,” he said. “I believe they may outperform the varieties we’ve been using so far and we are quite optimistic they’ll do very well here.” Continue reading

New Hamburg – An Ontario company that developed lunar rovers for the Canadian Space Agency has adapted the technology for use on earth. The resulting vehicle – called Argo J5 XTR (Xtreme Terrain Robot) — has applications across a variety of industries, including agriculture.
Ontario Drive & Gear Limited (ODG) is well-known to many consumers as the maker of Argo, popular all-terrain vehicles (ATVs) that can travel on rough terrain through land and water. The Argo J5 XTR is an unmanned robotic platform that travels on rough terrain in a variety of conditions ranging from war zones to underground mines — without putting an individual operator at risk.
“We’ve been working on space projects since 2008, but most years we only got to build two vehicles at a time – a primary and a back-up,” says Peter Visscher, chief technology officer for ODG. “We had an offer from a defence contractor to commercialize the vehicles, so we built a version for use on earth – and being Argo, we also made them amphibious.” Continue reading
Southwestern Ontario weather measurement system lets farmers use minute meteorological data

Farmers are notoriously keen meteorologists, but the weather information readily available to them isn’t always the most precise. That can be a bit nerve-wracking when your livelihood depends on conditions at the beanstalk level.
In an effort to make weather information more practical for individual farmers, AGRIS Cooperative Ltd., together with Wanstead Farmer’s Cooperative and Haggerty Creek Ltd. launched the AGGrower Daily Dashboard.
This lets them offer an up-to-the-minute rainfall and temperature data service using 80 automated and 200 manual weather stations.
Wirelessly connected and distributed at 10 kilometre intervals between Essex, Sarnia, Mount Brydges, and the northern shore of Lake Erie, the stations measure rainfall and temperature in their immediate area.
Gathered data is then fed back to a central database, which farmers can access through their computer or mobile device. The difference, though, is that those measurements can be taken by the metrerather than the kilometre. Continue reading

Bradford – Collaboration between vegetable growers, a farm organization, and a grower co-operative is leading to improved plant health and more efficient vegetable production in the Holland Marsh.
The Bradford Co-op, the Fresh Vegetable Growers of Ontario and individual vegetable growers in the Holland Marsh – an extremely fertile vegetable growing area near Bradford just north of Toronto – are collaborating on a project with the University of Guelph to test innovative technologies that will make their Integrated Pest Management (IPM) programs for key crops like onions and carrots more efficient and cost effective.
