Inputs

September 2017 – Ontario has long been a world leader in the adoption of biocontrols in floriculture crops.
September 2017 – One thing is for sure these days: nothing is for sure. Everyone in the greenhouse industry knows we’re in a global industry. Supplies, labour and produce are increasingly moved around the world in what we’re told is a good thing – “global trade.”
July 5, 2017, Leamington, Ont. – Greenhouse pepper growers of Southern Ontario have suffered some big losses over the last few years, all because of one little culprit: anthonomus eugenii, the pepper weevil. For many farms, the ill-intended stowaway was just a boogieman – “We better put out some pheromone traps, I heard they’re in town!”
May 2017 – 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.
August 2016, St. Catharines, Ont. – Dr. Michael Brownbridge is the research director in Horticultural Production Systems at the Vineland Research and Innovation Centre. He was a featured speaker at Grower Day 2016, discussing the various resources in the growers' IPM toolkit.
Jan. 26, 2017, Kingsville, Ont. – Kam’s Growers Supply Inc. has expanded with a distribution centre now operating in Kingsville.
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.
Oct. 11, 2017, Umeå, Sweden – Researchers at Umeå University and Wageningen University have discovered how plants can defend themselves against aphids.
October 2017 – This is the last part in a six-part series of articles on thrips (and other pests) integrated pest management, where we provide practical application tips and tricks, information on new technologies and how it all fits within an overall IPM program. Each article is accompanied by a short video demonstrating a technique or principle.
October 2017 – The pepper weevil has become a bigger nightmare for pepper growers in Leamington area. The swarming of pepper weevil in the Leamington area might be a result of the milder winters and more year-round greenhouse production, inter-planting schemes and lack of attention on greenhouse cleaning procedures that enhance the survivorship of pepper weevil. Ignoring just one adult weevil is a reason to take out an entire crop.
September 2017 – Aphids can cause significant economic losses on ornamentals by causing deformities, reduced size, or by merely being present on the plants. Such presence affects the aesthetic value of infested plants, thereby reducing or preventing their marketability.
September 2017 – I’m sure growers sometimes wonder what the heck scientists are doing behind closed doors all day in our labs and research greenhouses. Since it often takes several years of repetitious experiments to conclusively find an answer to a problem (or even longer to bring a new product or process to the market), I’m sure that, from the outside, it sometimes seems like things are at a standstill.
September 2017 – This is part 5 in a six-part series of articles on thrips (and other pests) integrated pest management, where 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.
Sept. 28, 2017, St. Albert, Alta. – It’s been a pretty good year for peat harvesting in Canada.
July 2017 – Over the past few years, Kwantlen Polytechnic University students have been working with local schools (elementary, middle and high schools) to help design gardens. In each case, it has been at the school’s request. This is critical, since it means they have ownership and therefore (hopefully!) commitment. Plans have been driven by specific constraints of the spaces available and any wants/needs of the school community, and these needs were in turn identified by doing surveys of all stakeholders.
July 2017 – As growers, many times we do things by going through the motions of what we did before and whether it worked or not. If what we did before worked we try to repeat it – but that is only if we kept records we can review before starting to grow crops we produced before.
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.
October 2017 – A longtime garden favourite, New Guinea impatiens can be an easy growing option for the greenhouse producer as well, with a few simple tips and techniques. That is true of the newer sun loving varieties like Sun Harmony as well.
August 2017 – A wildflower long tamed, growers and gardeners alike love coreopsis for its low maintenance and long life, but this staple still has a few surprises to share.
July 2017 – Growing bedding plants is always a challenge in the sense that over hundreds of varieties and cultivars are grown, nurtured and then sold or marketed to clients or customers.
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).
Jan. 15, 2016, Guelph, Ont. — The proposed Waste-Free Ontario Act marks a significant shift in how Ontario considers waste.
Nov. 27, 2015, Toronto — Ontario has introduced legislation that, if passed, would divert more waste from landfills, create jobs and help fight climate change.Currently, Ontario is generating too much waste, and not recycling enough, say government officials.
Sept. 22, 2015, Sumner, WA – The Million Bottle Club has announced its 2015 recipients, recognizing growers who have recycled more than one million plastic water bottles into plant containers.
Feb. 20, 2015, Twinsburg, OH – The company management of Myers Lawn and Garden Group along with Wingate Partners V, L.P. have acquired the Lawn and Garden business from Myers Industries, Inc.
Dec. 9, 2014 — As a bedding plant grower, you prefer to grow the items that are most profitable. Unfortunately, the demand for that item could be limited. We can only grow items that are in demand and work to make them as profitable as possible.
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.
