January 2017 – “The fact is that if we don’t learn how to recycle nutrients and water, we are doomed. We will start dying off from hunger. This is just one approach to prolong our existence on this planet.”
October 2016 – Silicon (Si) is the second most abundant element in the Earth’s crust next to oxygen . It is a major component of plant tissue. It is found in varying concentrations in virtually all living tissue, plants, animals and humans.
Sept. 2015 – This year, I have seen so many issues with calcium deficiency in bedding plants and vegetables that I decided to write about it in some detail.
According to fertilizer specialists Rob Rennie and Patrick Heffer,1 the industry has been facing a number of critical challenges, namely:
April 1, 2014, Southampton, U.K. – In the first study of its kind, research undertaken at the University of Southampton has cast significant doubt over the use of biochar to alleviate climate change.


My writing on the subject of nutritional deficiencies this month has been triggered by an e-mail I received from an experienced pepper grower.
Dec. 7, 2011, West Lafayette, IN — A Purdue University scientist and researchers in Japan have produced a new class of improved plant growth regulators that are expected to be less toxic to humans.
Nov. 6, 2009, Buenos Aires, Argentina – Prior research has reported the successful use of a technique termed “light manipulation” to affect plant height in some ornamental plants. Researchers in Argentina have been studying its potential with poinsettias.
Suggestions from growers often find their way into the  classroom labs
July 24, 2008 — Since it was first labelled for use on ornamentals in 1982, Bonzi plant growth regulator (PGR) from Syngenta Professional Products has long been regarded as one of the leading PGRs throughout the nursery and greenhouse industries. Through the years, Bonzi has been shown to consistently keep plants uniformly compact, hardy and well proportioned.
May 2017 – In Ontario, we continue to struggle with control of western flower thrips.  Even those growers religiously using preventive, mite-based biocontrol programs can suddenly find themselves throwing out a significant portion of their crop due to visible damage.
May 2017 – In this six-part series of articles on thrips integrated pest management, we will provide practical  application tips and tricks, information on new technologies and how it all fits within an overall IPM program. Each article will be accompanied by a short video demonstrating a technique or principle.
March April 2017 – At this time of year, the two-spotted spider mite makes its very predictable appearance in greenhouse crops. Despite our familiarity with this pest, it continues to challenge us.
August 2016, St. Catharines, Ont. – Bill MacDonald is a full-time professor in the School of Environmental and Horticultural Studies at Niagara College. He was a featured presenter at Grower Day 2016. He discussed the effectiveness of biostimulants with greenhouse crops, offering a timely update on these new crop management tools.
Feb. 23, 2017, Guelph, Ont. – A high-tech form of insect birth control connected to nuclear power could solve a devastating pest problem for Ontario farmers, says a University of Guelph researcher.
February 2017 – During early season, greenhouse crops are often considered as simple ecosystems with low biodiversity. Particularly, crops in modern greenhouses appear sterile compared to outdoor crops and this is because plants are grown on hydroponic systems in a closed environment.
March April 2017 – I write this a couple of weeks before his inauguration, and president-elect Donald Trump is in process of picking his cabinet. He’s done Education, Transport, Energy and, of course, all the military/security positions. In fact, he’s done all cabinet and senior advisory positions except for two. Right, he’s down to the last two and at this point, and he’s not appointed anyone to hold the Agriculture portfolio.1 (In case you’re wondering, the only other outstanding vacancy is Secretary for ‘Veterans Affairs’.) Firearms before food is such an interesting concept, don’t you think?
October 2016 – Talking about root zone is always fascinating to me because it is the foundation of all greenhouse crops and it is hidden from our eyes. The tops we can easily see but the tops depend on the roots, and the roots depend on the health of the tops!
September 2016 – Just recently, Dr. Tim O’Neil from ADAS in the U.K. spoke to Canadian growers on the topic of Root Mat Disorder (“Crazy Root,” as it’s called here). This has been seen on hydroponic cucumbers in the U.K. since 1993 and tomato crops throughout Europe (especially the Netherlands and France) a few years later.
August 2016 – Growing media for greenhouse crops fascinate me because as a greenhouse specialist in the early 1980s, I faced problems with the growing medium in which cucumbers were grown.
March 2016 — Roots are the foundation of plants we grow in greenhouses. In the February 2013 issue of Greenhouse Canada, I wrote about root health and it’s importance in crop management.
Jan. 7, 2016, Shenyang, China — Nitrogen (N) is an essential nutrient for plant growth, and nitrogen fertilization – including the application of manures – is a major management strategy in agriculture across the globe.
March April 2017 – Writing about root zones for greenhouse crops has been an important subject for me and I have written a number of articles on this subject in Greenhouse Canada.
January 2017 – Since most farmers start the growing season in December and January, the space at propagators is limited. Up to 48 heads per square metre spacing is not an exception. This results, in most cases, in a vegetative plant with a few tiny hairy roots.
Nov. 2, 2016, Whitby, Ont. – NOA Fisheries is hosting a three-day aquaponics course early next week (Nov 7-9).
October 2016 – A deleafing robot cleaned up the top award at this year’s GreenTech Show held in mid-June in Amsterdam.

Nov. 28, 2014, Surrey, B.C. — As sustainability increasingly takes centre stage and consumers seek out more responsible choices in all aspects of their lives, growers are in turn exploring options in their production.
