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.

Juvenile and adult Bemisia whitefly (Bemisia tabaci). There are 2 biotypes of this pest (“B” and “Q”) which look identical; however, their response to chemicals is very different.
Poinsettias cuttings are here! Unfortunately, they will likely arrive with unwanted “presents” in tow. This includes Bemisia whitefly, a pest that can be hard to control with natural enemies and can ALSO be resistant to pesticides. So what’s a grower to do?
By implementing some preventative measures RIGHT NOW, and understanding WHEN it’s appropriate to spray, you can help save yourself a lot of headaches later.

Do you have a strategy to help mitigate pests coming into your facility, like dipping cuttings upon receipt?
The CFIA has recently released the Floriculture Sector Biosecurity Guide. Despite it’s imposing name, this is an excellent “road map” to help protect your facility from unwanted pests. The Guide offers biosecurity strategies from the time plants come in the front door ’till they’re out in the compost bin.
Don’t have a facility-wide Pest Management Program in place? This guide can provide the framework. (Why start from scratch?). Already have a strategy to mitigate risks from pests at your farm? Compare YOUR plan with the Floriculture Guide to see if you’ve overlooked anything.

Citrus mealybug feeding on a flower stem.
Last year several consultants and I noticed something strange. A number of greenhouses in Ontario had noticeable infestations of mealybug in their poinsettia crop. This was the first time many in their 25+ year careers had seen this (e.g. see Mel Sawaya’s article in Greenhouse Canada Magazine).
It’s unclear yet if phenomenon will repeat itself this year (or perhaps affect even more operations), but growers should be on the lookout for this pest. Keep reading for more information about the potential cause of these mealybug infestations, and possible solutions.
