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?
