Hi,
I recently stumbled upon an organically certified product called ProAlexin. Has anyone here heard about it or used it on their orchids? It is supposedly a natural fungicide and can aid the plant in the uptake of nutrients. I have found very little information, but there seem to be two versions, one "Phyto-Elicitor" which enhances the plants defenses against pathogen, and one "Plant Nutrient Synergist" which increases nutrient uptake. One website actually lists orchids as one group of plants that can be treated. Below is a text from a newsletter that can be downloaded here:http://quantumgrow.co.nz/site/hydro...ents/Newsletters/Newsletter March 2009doc.pdf
------CITED TEXT--------------
What is it used for?
ProAlexin – Plant Nutrient Synergist contains bioflavonoids (synergized with organic acids), which act as “elicitors” to activate and enhance the plants production of phytoalexins to counter the risk of damage from pathogenic attach. Phytoalexins are antitoxins naturally produced by the plant. Reduced production of phytoalexins is due to several factors (genetic changes in the plant) caused by: plant stress; excessive use of synthetic agrochemicals (pesticides, herbicides, fungicides and synthetic fertilisers); temperature, humidity and climate. Increased level of phytoalexins production reduces stress, promoting plant vigour; all these factors result in a healthier plant.
Pro-Alexin is very effective on the following:
• Botrytis
• Brown fungal spots on lettuces and foliage
• Powdery Mildew
• Sclerotinia
• Pseudomonas

I think it would be great with an organic product that works proactive, but I there is always the risk of it being humbug. Does anyone have any experiences?
