This is the second blog post in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before you are faced with a problem. Posts over the next few weeks will focus on identifying problems, interpreting lab tests, on-farm disease monitoring, and water treatment options. These will be good refresher resources, so make sure to bookmark them.
When it comes to talking about disease-related issues in greenhouse crops, one point of confusion is often oven WHICH pathogens CAN be transmitted by water. Some are obvious – we all know Pythium is water-borne. But what about other culprits, like Fusarium or Erwinia? Should you worry about these in your recirculating water?
Read more to find out when to suspect your irrigation water versus other factors when it comes to disease.
Spring is just around the corner, and this is historically the time of year where we get more calls about disease pressure and problems in the crop. This year, we’ve decided to run a series of blog posts about water sanitation to get you reflecting on your own irrigation system before you are faced with a problem. Posts over the next few weeks will focus on identifying problems in the greenhouse, interpreting lab test results, on-farm methods for disease monitoring, water treatment technology options and more. These will be good refresher resources, so make sure to bookmark them for future reference.
With the holiday season over, it’s time to turn our attention to Spring bedding crops. Although here for a brief window, the diversity of these crops means you’re bound to encounter some sort of disease and insect problems.
One way you can head off issues is to plan and prepare now. This post has important tips on sanitation for common spring crop diseases, dipsandearly sprays to prevent key pests, as well as tips on where to spend your biocontrol dollars.

By now, you may of heard of the Tomato Brown Rugose Fruit Virus (ToBRFV), referred to more simply as “Rugose”. It is a viral disease that predominately impacts tomato plants, but also peppers, leaving fruit damaged and unmarketable.
It wasfirst detected in Israel in 2014 but has now been found in parts of North America.
If you are a Canadian ornamental grower that ALSO grows tomato liners as part of your spring crop selection, or if you grow ORNAMENTAL PEPPERS, here is what you need to know regarding Rugose symptoms, prevention and more importantly, regulations.
A new, potentially serious plant virus – the Tomato Brown Rugose Fruit Virus – is moving through crops across Europe and the U.S. As this virus can affect both tomatoes, peppers, and potentially some floral hosts, OMAFRA is running information workshops in Niagara and Leamington to answer grower questions about potential threats to our industry.
Read on for a description of the virus and workshop dates.
Rankled by root rots? Mystified by mildews? Bothered by Botrytis? We’re here to help!
Greenhouse Canada Magazine and OMAFRA are proud to be co-hosting a webinar series on ornamental disease control. Running from March to late April, this series covers topics from sanitation measures you should be adding to your management program, to the most effective fungicides for persistent pests like powdery mildew.

With the intense period of rain we just had, and with MORE rain coming on Friday, it’s time to think about Botrytis control and prevention. One of the most common and destructive diseases of greenhouse crops, outbreaks usually follow periods of cool, damp, cloudy weather. Unfortunately, I can’t order up more sun for you, but I CAN suggest some management tactics.
