Oedema on the young leaves in this begonia basket.
Oedema, that physiological disorder that appears during periods of low light and high humidity. There’s been quite a bit of it reported in Ontario greenhouses this spring, and unfortunately it’s related to the long rainy (or snowy!) spring we’ve been having. If you’ve noticed salt-like crystals, odd tumour-like growths or water-soaked spots on either side of your plant leaves this disorder might be the culprit.
The disorder affects a wide variety of greenhouse ornamentals. It’s usually noticed in spring crops like sweet potato vine (ipomea), geranium, begonia and/or petunia. Continue reading
The Premier’s Award for Agri-Food Innovation Excellence program recognizes outstanding agriculture and agri-food related innovators, including producers, processors, and agri-food organizations. Awards of up to $75,000 are available. Nominate someone you know now!
Although native bees and honeybees may just be starting to gather strength and are beginning to fly outside, other “B’s” have been of growing concern in the greenhouse for some time now.
These include common spring bedding crop problems like Botrytis cinera (aka grey mold), Broad mites, and leaf burn (from a variety of causes).
Keep reading for tips on how to manage these issues during this time of year.
Just a friendly reminder that the Vineland Research and Innovation Centre’s survey on pest management concerns and needs in the Canadian greenhouse industry needs to be filled out by this Friday (April 6).
This survey guides applied research and helps set industry priorities, which is why your input is so important.
What happens if you don’t fill it out?
One of the lovey scientists from VRIC is likely going to call you, that’s what. And if you’re anything like me, I’d MUCH rather fill out an online form when it’s convenient for ME, rather than take the time to go over questions on the phone.
To take the survey, click back to the original blog post here, and follow the instructions.
We need to pick your brain!
Let’s face it; it can feel like there’s never enough time in the day. Extra tasks (even those that only take a few minutes) can seem impossible to squeeze in. Especially this time of year.
But some tasks that seem annoying now can have a big payoff in the future. Because if researchers, extension agents and industry groups know exactly what you need to be successful, we can help make these things a reality.
The Vineland Research and Innovation Centre has recently taken up the rather thankless job of conducting a survey on pest management implementation and needs in the greenhouse industry.
Why is this a necessary evil? Because it gives them (and us) information on:
- Pests to focus research on
- Where pest management dollars are being spent, and where programs can be refined
- Pest management needs in the industry (here’s your chance to indicate specific pesticides or bios you’d like to see available!)
- How best to reach growers with new information
I encourage you all to click “Read More” on this blog post and follow the link to the survey BEFORE April 6, 2018. Below I have detailed the kinds of information you’ll need at your fingertips to help make taking it go a bit more smoothly.
You might have heard that a new cost-share program, GreenON Agriculture was announced last week. This program is designed to help Ontario farm businesses reduce their carbon footprint, and greenhouses are eligible!
This program will be of interest to greenhouse operators who are concerned about rising energy costs, and want to make their operations more energy-efficient.
