Quality Control of Insecticide Spray Applications

Just because a pesticide was applied to a crop field or greenhouse doesn’t necessarily mean that the target pest was actually controlled. Nansen explains how frequently it happens that pesticide spray coverages are both low and inconsistent and why it should be a major concern to growers.

Nadine Stielow

Bug-Eyed About Biocontrol - A Grower's Perspective

Success using biocontrol is a process that takes commitment and dedicated attention to detail. But what if that effort turns into effort-less and your pest management program just becomes part of your business ‘schtick’. What if you’re known as much for your plants as you are for your healthy #growclean production practices in terms of your team, your customers and the public.

Enjoy this half hour session on the good, the bad and the ‘buggly’ as Nadine shares her excitement and passion for biocontrol. It’s her grower/owner perspective on what works, what doesn’t and the lessons learned since implementing a biocontrol system. Bios are the first line of defense and this message is prevalent in both the company’s new fresh greens hydroponic venture and in the day-to-day business culture. Be on the biocontrol bus! Be known as a local advocate for using good bugs to get the bad ones.

Interaction of Lighting with Microclimate & Energy Balance

Year-round production is important for providing high quality produce to consumers, for maintaining/increasing market share, and for competing successfully in national and international markets. Because of the low natural light condition during the winter in Canada, artificial light is needed to supplement natural light for year-round greenhouse fruit vegetable production. The supplemental lighting not only increases light intensity, but also adds significant amount of energy into the greenhouses, affecting the energy balance and plant microclimate, which in turn influences energy costs and plant growth & development.  Read more


Jan-Kees Boerman

Influence of Air Quality in Greenhouses

Due to CO2 fertilization in greenhouses, air quality is changing during the season. Trace gases of ethylene and NOx influence crop quality and crop growth. What effects can you expect to see and how do these influences relate to light, photosynthesis and yield?

Successful Greenhouse Operations in a Rapidly Changing World

Over the last 50 years the greenhouse industry has evolved in ways no one could have predicted and it is a sure bet that it will continue to do so. Can past history help us prepare for the changes the greenhouse industry will face in our rapidly evolving world?  Hammer will explore general greenhouse operation questions regarding technology, equipment purchases, crop choices and expansion. Peer into the crystal ball to see how the greenhouse grower’s job might change yet remain the same as the industry advances.  Is there any chance a computer can replace the “grower” position?  This presentation is intended to stimulate thinking.  The past may not always predict the future; however, past knowledge and experience is useful to avoid repeating mistakes.

Managing Emerging Pest Threats: Lessons learned from Pepper Weevil

Though specific pests may change and there is no way to predict the next emerging pest, there are some precautions that all growers can take and processes that can be developed on the farm to help prevent or mitigate the challenges of a new pest. The basis of these recommendations comes from the experiences of the Ontario greenhouse vegetable growers while learning to manage pepper weevil, an unregulated pest.

Innovative Approaches for Disease Management

A number of disease issues caused by plant pathogens can affect edible crops grown in the greenhouse. Current management guidelines rely on sanitation, crop and climate management practices, and the preventive or curative application of biopesticides or conventional pesticides. There are several novel approaches to manage pathogens causing diseases on greenhouse vegetables; however, most of these approaches are not yet available to Canadian greenhouse growers for disease control. The background science on these technologies and updates on the status of scientific knowledge will be presented. Their potential will be discussed in the context of greenhouse vegetable production, as well as current hurdles to their application by greenhouse growers in Canada and across the world.
