Advancing Leading Edge Horticultural Lighting Technology

According to resent research, the maximum efficacy of LED lighting is very close to reaching its theoretical maximum efficacy.  In this talk, we discuss the results of our ongoing efforts to propel efficacy beyond this threshold through strategic integration of AI and how this technology can reduce Greenhouse Gas Emissions in Agriculture and improve the bottom line for growers.

BUGS, BULBS & BIO-CONTROL: How artificial lighting impacts beneficials?

Artificial lighting (AL) using light-emitting diodes has proven to be a valuable tool for supporting the productivity of greenhouse crops. Additionally, greenhouses are ideal for implementing biological control programs involving beneficial insects (i.e., parasitoid wasps and predators). However, sensitivity to the light spectrum differs for plants and insects, including beneficials. To what extent does AL influence insects in a horticultural context?

First, we will review the current knowledge on the impact of lighting on insect behaviors affecting biological control. Then, we will present some original results comparing the combined effect of AL under different conditions on the control performance of the predatory bug O. insidiosus against the Western flower thrips (Frankliniella occidentalis), as well as the morphological and physiological responses of greenhouse cucumber (Cucumis sativus). Lighting conditions conducive to biological control by O. insidiosus have been identified, suggesting that AL can support both pest control performance and crop productivity.

Tracking ToBRFV Lineages Using a Novel Genomic Sequencing Method

The ToBRFV is a highly virulent and robust plant pathogen that evades plant virulence resistance genes. To track this virus, as well as understand its phylogeny and evolution we devised a novel genomic sequencing method and lineage prediction tool. In combination, these tools allow the identification of specific ToBRFV strains. We have applied these tools to identify ToBRFV strains in different samples, including infected tomato crops, and have found that this virus is highly abundant in wastewater.

Superspreader “human” - How to get ToBRFV under control

Tomato brown rugose fruit virus (ToBRFV) causes serious or even existence-threatening financial losses in tomato cultivation worldwide. Like other tobamoviruses, ToBRFV is easily transmitted mechanically, resulting in the infection of entire tomato crops within a very short time. Humans are mainly responsible for the spread of ToBRFV through contaminated clothing, shoes, hands or vehicles.In the studies, practice-relevant contamination and transmission ways of ToBRFV were scientifically investigated and, based on this, hygiene strategies were developed with a focus on the anthropogenic spread of ToBRFV. The choice of a suitable product and the implementation of effective and practicable hygiene concepts were identified as key factors in hygiene management.

It's on everything, everywhere, all at once: Lessons from managing ToBRFV in the UK

Tomato brown rugose fruit virus has rapidly emerged as the major viral disease affecting global tomato production. The UK has experienced relatively few outbreaks, and (thus far) eradication action has been successful. Collaboration with UK growers, plant health inspectors, risk managers, and international research groups has ensured that research has been focused on the growers needs, initially focussing on early detection from the plant, and the efficacy of disinfection methods for eradicating the virus. This focus has now shifted to understanding the mechanics of outbreaks, both at the global level in supporting genetic diversity studies on the source of infections, and within the glasshouse trying to understand the sources and risk of environmental residues both as a cause of subsequent infections and as confounding factors in diagnostics.  The presentation will discuss recent and current work supporting UK tomato growers combatting this virus.

Managing the Emerging ToBRFV Using Ozone Treatment & Disease Resistance

The emerging tomato brown rugose fruit virus (ToBRFV) poses a serious threat to tomato production worldwide. This highly contagious tobamovirus breaks disease resistance genes in tomato. To manage this emerging virus in greenhouses, it is necessary to incorporate an integrated pest management. In addition to planting certified tomato seeds tested free of ToBRFV, you would need to select effective disinfectants for cleaning and disinfection of tools, equipment and facilities. In this study, we demonstrated that ToBRFV released to water run-off in a hydroponic system caused a new infection on tomato plants. However, a cold plasma ozone treatment deactivates the virus in ToBRFV-contaminated water solutions. To develop tomato with resistance to ToBRFV, we screened many USDA tomato germplasm and identified a source of resistance in Solanum pimpinellifolium, which could be used for tomato breeding. By incorporating proper disinfection, ozone treatment and disease resistance, it is possible to manage this emerging virus.

Hype or Hope? What's Driving the Sustainability Push?

There is a lot of buzz around "sustainability" in the agri-food industry and many companies are developing sustainability initiatives as a result. I'll discuss the drivers of sustainability demands in agri-food value chains, current initiatives out there, and how this push toward sustainability may affect your operation in the future (if it isn't already). I'll also cover opportunities for growers and organizations to address this trend proactively.

Where next in energy saving for high-tech greenhouse horticulture?

The discussion will focus on a collaborative research project between Grodan and Philips Horticulture LED Solutions. Our aim was to reduce total heat input into a full LED lighted tomato crop >40%.

So what’s the dilemma? In winter when you have a minimum radiant heat input from the sun combined with energy efficient LED lights, how can you work with lower pipe temperatures, stimulate sufficient plant transpiration and nutrient uptake, whilst at the same time control greenhouse humidity?

The answer is you have to do something that’s not been done before, you have to set a vision for the new ‘norm’.

We shall talk about how we overcame our dilemma and achieved >50% lower heat input compared to a reference tomato grower with the same variety.

If you at not a tomato grower, or you do not grow with lights the approach to energy saving is also transferable to your situation.

Landfill diversion of greenhouse crop residues: Current options, opportunities and challenges

The greenhouse sector in the Leamington area currently landfills approximately 150, 000 tonnes of fruit grade-outs, vines and growing media annually. With no new landfill construction planned, it is anticipated that landfills in the area will run out of space within the next five years. Due to rising costs of transportation and landfill tipping fees, many growers have already begun finding alternatives for their crop residues. The presentation will discuss various strategies that growers are currently using to manage their crop residues such as diverting grade-outs to food and cosmetics industries or changing sorting practices to reduce grade-out volumes. The presentation will also discuss new opportunities under development that may become available within the next year such as entomocomposting, dehydration of vines for use in biomass boilers and upcycled growing media.

Pure Life Carbon

Growing Canadian Greenhouse Crops in Charged Carbon

Controlled Environment Agriculture (CEA) is expected to quadruple in value within the next decade due to population growth, scarcity of water, changing environmental conditions, and consumer pressure for less pesticides and chemicals. Industry is pressured to find more efficient and sustainable means of production, yet there has been no innovation in the last 50 years since single-use soilless growing mediums. Pure Life Carbon developed a standalone soilless growing medium, Charged Carbon, for CEA that is reusable, economical, and performs at par or better than conventional growing mediums – making it a viable solution for food security and the environment. This talk will provide an overview of the ongoing collaborative industry trials on using Charged Carbon in various greenhouse crops in Canada.
