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.
Spring is just around the corner, and this is historically the time of year where we get more calls about disease pressure and problems in the crop. This year, we’ve decided to run a series of blog posts about water sanitation 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 in the greenhouse, interpreting lab test results, on-farm methods for disease monitoring, water treatment technology options and more. These will be good refresher resources, so make sure to bookmark them for future reference.
Ever wonder how water related disease issues just seem to pop up out of nowhere? You’ve never had a problem before, but suddenly things just aren’t looking right. The truth is that problems often go unnoticed while pathogen levels are low. Knowing potential innoculum sources and practicing good preventative measures can help to reduce the risk of a bigger problem.
