Over the past few years, we seem to be battling a whole new posse of thrips species. First it was onion thrips moseying on up into our chrysanthemums and gerbera. Then, it was Parvispinus, which was like a runaway train in our tropicals. Now, it’s Japanese flower thrips ( Thrips setosus ), riding into town on crops like hydrangea . To make sure growers have the latest information on these pests, GrowON is running a 3 part webinar series on thrips besides western flower thrips. The first installment will be on Japanese flower thrips on August 20th . Read on for how to register for this free webinar. A lineup of thrips species that attack greenhouse ornamentals.

With July being the beginning of poinsettia season, as well as the time growers are starting many tropical plants for next spring, it’s time to be thinking about managing pesticide resistance . Pesticide resistance readily develops in populations of key greenhouse pests, including Bemisia whitefly, spider mites, and more. So how do we avoid an uphill run on the resistance treadmill? Hannah Fraser, Horticulture Entomologist with OMAFA, shared her decades of experience battling resistance issues in fruit crop pests in a GrowON webinar recorded last summer. For those that missed it, I thought now would be a good time to post the video on the blog. (As always, you can find all of our previous GrowON webinars on the ONFloriculture Youtube channe l .) Keep reading to watch the video as well as links to other resources on resistance management.

Christmas in July? Not quite, but poinsettias are making their way into greenhouses across Ontario, and they always arrive at the hottest time of the year. Nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop. Read on for production tips and how to manage this seasonal favourite in the greenhouse. Only looking for certain information? Choose from the list below: Nutrition Managing the Greenhouse Environment PGR Applications Resources & New recommendations Nutrition Poinsettia are picky eaters – the conditions need to be right for them to uptake fertilizer and avoid deficiencies. Maintaining a pH of 5.5 – 6.5 in the media and using fertilizer with a nitrogen concentration of 150 – 300 ppm will help you avoid most nutritional disorders. It’s essential to start feeding early, about 10 days after sticking, to prevent lower leaf yellowing (nutrient deficiency) and to produce larger leaves at the bottom of the plant. Rememb...
