Since 2019, Ontario’s greenhouse vegetable growers have been dealing with tomato brown rugose fruit virus, which makes tomatoes unmarketable.

Anti-viral technologies can reduce pathogen transmission in the greenhouse

Pandemic battle to reduce COVID transmission gave researchers a unique opportunity to study anti-viral potential in tomatoes

Three new anti-viral technologies could help prevent the transmission of both COVID-19 and a plant virus that affects tomatoes in commercial greenhouses. That’s according to a recent Ontario Greenhouse Vegetable Growers (OGVG) research project to refine and apply technologies used in other industries to greenhouses to test their effectiveness at inhibiting virus transmission. The project […] Read more

How greenhouse growers can reduce energy costs

Dehumidification technology can be a useful tool to control humidity and heat loss

High humidity levels inside greenhouses are a byproduct of growing crops indoors. Left uncontrolled, humid air can reduce crop growth and result in poor quality produce, so growers have traditionally resorted to ventilation to manage the issue. While effective, this strategy also causes heat loss, which can increase a farm’s energy costs. The Ontario chapter […] Read more


greenhouse LED lighting on peppers

Smart LED grow-lights system supports year-round pepper production

Expanding production would boost competitiveness of the Ontario greenhouse vegetable sector

Innovative lighting technology could allow Ontario vegetable greenhouses to grow peppers all year long. That’s the result of a project funded through the Greenhouse Competitiveness and Innovation Initiative (GCII), which also found that the smart LED grow lights system results in higher yields, better quality and more uniform crops. Why it matters: Year-round production of […] Read more
