Participate in Developing an Irrigation Strategy for Niagara

The summer of 2016 was unusually dry across much of the Niagara Region. Prolonged dry conditions highlighted the need for access to irrigation water and the consequences of inadequate irrigation on crop production.

A number of grower organizations, working together with Niagara Region, were approved for a Growing Forward 2 grant to develop an Irrigation Strategy Action Plan for Niagara. The focus of this work is on farmland used for horticultural production, including grapes, tender fruit, nursery and greenhouse production, below the escarpment. The work is important for the future of your farm and your neighbours. Continue reading

Upcoming Webinar: GO-CALC – Modelling Energy Use and Savings in the Greenhouse

Now that the mums are gone, and the poinsettias are getting ready to colour up, it’s becoming clear that winter is just around the corner.  With the colder temperatures outside, comes the ramping up of you heating system. Remember those energy bills from winter’s gone by? Have they got you thinking about doing some energy-efficient upgrades in your greenhouse?

The engineers at OMAFRA have been especially busy this year building GO-CALC – a tool to help estimate your energy use in the greenhouse AND how retrofits can help to make your greenhouse more energy-efficient!  The tool shows how those energy-efficient upgrades like energy curtains, new greenhouse coverings and boiler upgrades that you may already be planning for your greenhouse can help you save energy.

4 Ways You May Be Killing Your Predatory Mites, and How to Check!

PowerPoint PresentationNote: This is a re-post because it now comes with an awesome new video of how to monitor you mite sachets!

Recently, I had an interaction with a grower where their long-standing biocontrol program for thrips suddenly seemed to be failing. After a (too long) investigation by  myself, the grower, and consultants, we found out the horrible truth: their predatory mites were being MURDERED (Duh dun DUHNNN!)… By improper storage.

This post focuses on whether YOU might also be guilty of mite murder, and how to make sure your mites are still alive and kicking in those little sachets.

(And yes, I’ve stooped to the level of click-bait titles).

Fainting “Freedom Red”? Wilting “Whitestar”? Potential causes of Poinsettia collapse, solutions, and the importance of testing.

DSC_1230

Wilting  of a poinsettia plant on a bench of otherwise healthy plants could be Pythium root rot. But then again, it might not…

From now until mid-November is when you’ll most likely see plant losses in poinsettia due to severe wilting. These losses can be considerable: anywhere from 2-15% in Niagara operations in past years, with disease pressure seeming especially high this year.

Pythium may be considered the most “likely” culprit in Poinsettia in this area, but this isn’t always the case, and misdiagnosis can mean wasted fungicide applications. Read on for a list of likely suspects and appropriate control measures.
