Indoor Farming - Why, Where, When!

Indoor farming is necessary because the existing food supply chain is vulnerable, strained, and unsustainable and requires a new agronomic approach in which growers must reconsider traditional plant management assumptions. To ensure that indoor farming will ultimately be profitable, fulfilling the promise of efficient resource use, we must continuously evaluate the way we farm indoors. Indoor or vertical farming is here to stay. To what extent it will complement traditional farming remains to be seen. In the meantime, indoor growing presents a novel form of food production, and agriculture as we know it is entering a new age! Plenty has invested more than 400 million dollars in plant science and engineering research to create the ideal plant growth platform making it possible to grow anywhere in the world.

 An Integrated Approach to Prevent Emerging Viral Disease Outbreak

In recent years, greenhouse vegetable growers are experiencing increased threats posted by several emerging viruses, including tomato brown rugose fruit virus (ToBRFV) and pepino mosaic virus (PepMV) in tomato and cucumber green mottle mosaic virus (CGMMV) in cucumber. These seed-borne and mechanically transmitted viruses are difficult to control. In order to bring these emerging viruses under management, three main parties, including seed companies, nursery propagators and greenhouse growers, would need to work together to prevent virus spread and disease outbreaks. Learn how an integrated approach can make it possible to protect greenhouse vegetables from emerging viral disease devastation.

Early Detection of Bacterial Canker in Greenhouse Tomato Crops

Early detection would allow growers to identify and treat bacterial canker outbreaks more effectively and reduce losses. Human scouts rely on their eyesight for visual inspection but yet our eyes only see the visible portion of light, whereas specialized cameras can potentially detect disease earlier using non-visible light such as infrared. At Vineland Research and Innovation Centre, we have studied the spectral light responses of healthy and diseased plants. This presentation will summarize our findings so far, which indicate that early detection of bacterial canker on greenhouse tomato crops is possible up to 10 days before it is visible to a human scout.

Casting a Light on IPM 

Suncor Energy Inc. has developed photosensitizer formulations that cause high mortality rates in common greenhouse pests. These novel, photodynamic insecticides are non-toxic derivates of natural compounds that fit into an ecosystems-approach of growing food more sustainably. Photodynamic insecticides have proven to be as effective as registered synthetic chemical pesticides and can be applied with equipment currently used in greenhouses and in the field. Pieterese reports on trials conducted at Vineland Research & Innovation Centre.

The Path to Autonomous Growing: What, Why, When & Where

AI & data based growing has been on the rise. AI can assist and, in some cases, even outperform the top growers. However, most greenhouse operators still do not know whether they are ready to adopt AI, are uncertain how it can help their operation or how it works, leery of the cost and unsure whom to trust. In this talk, we will discuss the path to autonomous growing, and share our experience and lessons learned from our win at the 2022 international autonomous greenhouse challenge organized by Wageningen University & Research in the Netherlands to sustainably grow vegetables via fully automated control with the use of AI. The Koidra-led team, Koala, beat 46 teams from 23 countries to become the only AI team in the world that outperformed the Dutch reference growers by 27.8% in net profit with the lowest operation cost and highest energy saving.

& Friends!

Air-assisted Sprayer Technology
Worth it, or does it blow?

This workshop will run Wed. AM, Wed. PM and Thurs. AM.  There is no cost, but pre-registration is required as space is limited.


The aesthetic value of ornamental plants requires a near-zero tolerance for insect pests, which cause up to 10% of crop losses per season. Controlling them with insecticides is a difficult proposition. Ideally, each combination of canopy morphology, planting architecture, pest and chemistry would have a specific sprayer designed to optimize coverage and efficiency. This is economically unrealistic. Instead, many producers utilize technologies that rely on high water volumes and hydraulic pressures to “drench” targets indiscriminately, which raises humidity, dilutes the products and may not help improve coverage. Air-assisted spraying can be a viable alternative (and an improvement) over these approaches. We will demonstrate where/when this technology may be a good fit.

Homegrown Heroes: Development of native predators for greenhouse IPM

With a few exceptions, we are still using the same biocontrol agents as 20 years ago. Meanwhile, European growers have had good success integrating new species of generalist predators into their IPM programs. Unfortunately, regulations in Canada and the US prevent the importation of non-native generalist species. This created opportunities to bring new North American biocontrol agents to market, to devise efficient ways of producing and using these natural enemies, and to develop robust integrated crop management strategies that support their use. Hear about new biocontrol agents developed at Vineland, grower experiences and a look at what is coming next.

The Bug Hunters: Developing new & native biocontrol agents for IPM in Canadian greenhouses

In today’s global regulatory environment, the importation of non-native biocontrol agents into new areas is increasingly restricted, owing to concerns of non-target effects by introduced species. As such, finding new agents to target a diversity of greenhouse crop pests requires surveys of native species. Along with ongoing greenhouse trials aimed at establishing best practices for application, this work represents the foundation for commercial development of native biocontrol agents for application in Canadian greenhouse crops.

Dealing with Molds, Mildews & Other Nasties That Want to Eat Your Crop

Pests and diseases are part and parcel of every crop production system, and cannabis is no exception. There are no rescue products approved for use on this crop, so successful management strategies must rely on a solid understanding of the different crop threats, conditions that promote their incidence and impact, and cultural and biological approaches that promote plant health and mitigate pest and disease threats. In this session, we will consider the primary biotic challenges in greenhouse/indoor cannabis production and some of the tools that can be used to reduce crop risks and keep pests and diseases in check.
