Is there scientific evidence for camomile tea to prevent damping off?
Joyce Schillen wrote in a tip sheet on this site to use chamomile tea to prevent or treat early damping off of seedlings. This is also found in multiple places on the internet. Just wondering if anyone has ever done a scientific test of that or a little experiment with two halves of a seed tray ect?

There are hints in the scientific literature where chamomile has antimcrobial qualities. Most are in reference to bacteria and viruses. The only piece that actually tested medicinal plant infusions saw little or no fungal activity. However, the Extension bulletin below lists chamomile for damping off. http://extension.oregonstate.edu/gardening/how-sprout-seedlings-life-indoors
