Here in Canada, we’ve been talking for years about research on the highly effective method of dipping your poinsettia cuttings in low-risk pesticides to reduce starting whitefly populations.
Thanks to Dr. Rose Buitenhuis (VRIC), Cary Gates (FCO) and BioWorks, the label for BotaniGard WP has now officially been expanded to include dip applications. This now adds to our arsenal (see below for more dip products).
Read on for the current BotaniGard label and how dipping can help improve your Bemisia whitefly program this year, whether you’re using pesticides or biocontrol.

ToBRFV is a new virus on the greenhouse scene.
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.

We are ecstatic to report that the webinar series “LET’S TALK DISEASE” hosted by Greenhouse Canada Magazine and OMAFRA has had high interest and participation from growers.
Running from March to late April, this series covers topics from sanitation measures, to the most effective fungicides for persistent pests like powdery mildew.

The next CAP intake for producers, processors and other agri-businesses is March 22 through May 6.
Please see the link here for the news release.
More information will be available on the websites of the Ontario Soil and Crop Improvement Associationand the Ontario Ministry of Agriculture, Food and Rural Affairs on or before March 8, 2019.
Examples of projects that can be funded under CAPS include:
- Innovative improvements to your greenhouse that promote biosecurity and limit the spread of insect pests from imported plant material
- Education, planning and training projects that improve plant health
- Preventing field pests from accessing your crop (e.g. screening)
- Upgrades to sanitation and work-flow that prevent spread of pathogens
- and other projects, as long as they promote plant health and safety!

If you were at the Canadian Greenhouse Conference (or are regularly reading this blog!) you’d know we’ve recently identified Onion thrips as a pest of floriculture crops in Ontario (see this post).
Outside of Ontario? Well, this still may apply to you, as a recent study in France also indicated that up to 47% of pest thrips in floriculture greenhouses were Onion thrips. So, this issue could be wide-spread.
My last post covered the extent of the problem in Ontario’s industry. This post will help you identify if YOU are dealing with Onion thrips (OT) along with Western flower thrips (WFT), and what to do about it.
Bemisia whitefly (Bemisia tabaca) adults on poinsettia. In high pressure years, poinsettia plants can quickly become unsellable due to this pest.
The floriculture industry in Ontario seems to have mostly avoided heavy aphid AND thrips pressure this spring/summer. But from everything I’ve been hearing, we are NOT going to be that lucky with whitefly on poinsettia this year.
This post goes over preventative measures that should be taken as soon as cuttings come in the door, biocontrol programs for whitefly on poinsettia, and WHEN and WHAT to spray for this so you can avoid resistance issues.
