Nothing new to report on my plants, they are all growing happily now. This itself is worthy of discussion in the context of how much trouble my classmates seem to be having with Pythium. Many poinsettias had to be removed but none of mine have developed any symptoms. However, this does not mean that the pathogen is not on my plants. The fungicide that was sprayed in the greenhouse may prevent it from spreading to my plants.

Peter postulated as to how the outbreak started, and his hypothesis is that spores on the floor came into contact with the hose when it was left on the floor. The water that was allowed to pool on the floor would have helped maintain not only the fungus itself, but also the algae that feeds its vector: fungus gnats.

I also forgot to mention yesterday that we planted snapdragons, but none have been assigned yet to students. Soon I will be reporting on that too.
