This post was written by Fadi Al-Daoud and Cara McCreary, greenhouse vegetable specialists with OMAFRA, and originally appeared on the ONgreenhousevegetables blog.
The quality of water and nutrient solution used in controlled environment agriculture (CEA) production systems, such as greenhouses and vertical farms, is one of the most important factors that affect plant health and yield. Growers monitor water and nutrient solution quality by sending samples for analysis to determine the levels of nutrients and salts. They also use sensors to monitor pH and electrical conductivity (EC) regularly to determine necessary adjustments for the nutrient solution. Growers may also analyze the microbiome, the genetic material of all the bacteria, fungi, and viruses that live in their water and nutrient solution, to evaluate levels of harmful pathogens, such as Pythium and Phytophthora species that cause root rot.

Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other Poinsettia issues.
Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop. Read on for common pitfalls and how to avoid them.
This post on poinsettia problems was contributed to by Drs. Chevonne Dayboll and Sarah Jandricic.
When poinsettias get problems, they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

Dipping poinsettia cuttings to help lower Bemisia numbers was investigated and perfected by the Biocontrol Lab at the Vineland Research and Innovation Centre in Ontario.
Although we’ve been talking for years here in Canada about dipping your poinsettia cuttings in low-risk pesticides, some growers have yet to take the plunge.
This preventive technique improves efficacy of BOTH biocontrol and pesticide programs for Bemisia, since it lowers your starting pest pressure.
If you’re still unsure of how or when to apply cutting dips, check out the rest of this post.

On May 14, 2020 the ministry announced the launch of the Agri-Food Workplace Protection Program for Producers. However, many in the greenhouse sector had already made pro-active improvements to workplace safety in light of Covid-19.
If you fall into that category, the program is now accepting applications for changes made as far back as March 15 2020. Applications are being accepted until funding runs out.
The program has also been simplified to provide faster assistance by eliminating pre-approval. Growers can now submit eligible expenses up to the farm maximum ($7500). This now includes accommodation and/or transport costs related to outbreak prevention. More program details can be found below and on the OMAFRA website.
