Its a busy time in the greenhouse, but our next topic is timely! Rot rots like Fusarium, Pythium and black root rot are often the bane of spring bedding crops. Dr. Mary Hausbeck, a Distinguished Professor from Michigan State University, is going to share her vast knowledge on this topic, including which fungicides work best. Check out the details below, and don’t forget to register!
Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other poinsettia issues.
Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop.
Read on for common pitfalls and how to avoid them, and for some great video resources on poinsettia production.
When poinsettias get problems, they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

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.
Okay, so Poinsettia don’t really get that many problems. But when issues arise, they can hit a crop fast and hard. Whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

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.
