Media filters can be an important step in water treatment: see this article in Greenhouse Grower.

This is the 6th article in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before a problem occurs. 

If you’re following our series on water sanitation, you saw that previous posts covered where problems are likely to occur in your greenhouse, the types of pathogens found in waterwhere and how to sample your water and getting and interpreting a DNA test for pathogens in your water.

This post covers water treatment options, and was written by C. Dayboll with input from Phytoserv and Soil Resource Group.

This is the fourth article in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before you are faced with a problem.  The first post covered where problems are likely to occur in your greenhouse ; the 2nd covered the types of pathogens found in water and the 3rd covered where and how to sample your water.

Once you’ve got your water sample, this post will cover why water DNA tests are useful, and how to interpret the results. This is the next step towards identifying and then treating your water issues to prevent unnecessary fungal or bacterial disease in your greenhouse crops, and potentially save you thousands of dollars in crop losses or fungicide applications.

These posts make good refresher resources, so make sure to bookmark them!

Surface Water Quality Management Webinar for Growers – Jan 26

Reposted from ONnurserycrops

Dealing appropriately with water issues is arguably one of the most important concerns facing today’s horticultural sector. There are numerous regulations at municipal, provincial and federal levels that govern access to water as well as the implications associated with run-off water.

Growers have responded by constructing elaborate pond and water recycling systems but are now challenged to maintain the quality of water in their pond systems to keep their modern irrigation systems operable.

In this webinar Dr. Jeanine West will share water quality management strategies based on her expertise and preliminary research findings. Time will be allocated for Q&A. Keep reading for registration information.

Which Pathogens Should You Worry About in Your Water?

This is the second blog post in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before you are faced with a problem.  Posts over the next few weeks will focus on identifying problems, interpreting lab tests, on-farm disease monitoring, and water treatment options.  These will be good refresher resources, so make sure to bookmark them.

When it comes to talking about disease-related issues in greenhouse crops, one point of confusion is often oven WHICH pathogens CAN be transmitted by water.  Some are obvious – we all know Pythium is water-borne.  But what about other culprits, like Fusarium or Erwinia? Should you worry about these in your recirculating water?

Read more to find out when to suspect your irrigation water versus other factors when it comes to disease.
