Do you use twitter? Agriculture and Agri-Food Canada is planning a Greenhouse Innovations Tweet Chat on Tuesday, April 11 from 2pm – 3pm EDT. This event is one of five Science Social Media Takeover Days planned throughout the year. The Tweet Chat is designed to engage research staff, greenhouse growers and greenhouse industry stakeholders, and the general public about Greenhouse Innovation and Vertical Farming.
Given that it’s the season for pest problems like aphids on spring crops, I’d like to remind everyone of an important new pest management tool we have at our disposal.
Thanks to the hard work of Cary Gates at Flowers Canada Growers, and OMAFRA’s Jim Chaput, Beleaf (flonicamid) can now be used as a drench on greenhouse-grown ornamentals and cut flowers.
Read on for more details regarding the expanded label and potential phytoxicity issues.
Impatiens Downy Mildew – an example of a recent threat to Canada’s floriculture industry.
The CFIA is looking for input from growers by April 30th to help develop a national strategy for protecting Canada’s agriculture from new and emerging risks.

To find out the punchline to this joke, you’ll have to attend the Grower Session of the upcoming IOBC “Integrated Control in Protected Crops” Meeting on June 7, 2017 in Niagara Falls. Read on for details.
Spring is on its way, and with cold nights and warmer days we are seeing a common spring problem – poor air quality damage on spring bedding crops. Symptoms, solutions and preventative measures are included in this 2017 update to a previous post.
Natural gas and propane are popular choices when it comes to heating a greenhouse. The products of burning fuel are carbon dioxide (CO2) and water (H20); both compounds we know are good for your plants. However, combustion is often (if not always) incomplete, and impurities such as carbon monoxide (CO), sulfur dioxide (SO2) and ethylene (C2H4) are also released leading to poor air quality if your heater is not properly vented.
Typically symptoms from ethylene damage and sulfur dioxide damage can been seen fairly quickly after exposure.
Figure 1. Signs of ethylene damage include leaf curling and epinasty, seen here in A) New Guinea Impatiens and B) lettuce seedlings.
In the short term (a few hours to a few days), ethylene damage results in leaf curling, epinasty (leaves bending downwards from the petiole) and flower drop. If the stress continues over a Continue reading
On Saturday afternoon (Feb. 18th) from 2- 6pm at the Vineland OMAFRA office there will be a “Biosecurity Workshop”run by the Ontario Soil and Crop Improvement Association.
This workshop is targeted to greenhouse and hort producers. It will provide the necessary background for growers to submit applications to the Growing Forward 2 Program for biosecurity and pest control projects. Attendance at a biosecurity workshop is a necessary to apply for GF2 funding under this stream.
There is no cost for this workshop and all are welcome. Please register at ontarioprograms.net or contact Margaret May at email@example.com
