RE: question about the Neem Recipe
Hello. Some time back I got this recipe from Tapla about using neem [thanks, Tapla]:
Start with a pint of very hot water in a 1 qt spritzer bottle. Then add a tsp of cold-pressed, pure neem oil and few drops of Murphy's Oil Soap (or non-antibacterial dishsoap). Shake well. Add a pint of 70% rubbing alcohol. Shake again and spritz. Make sure to cover all surfaces, especially the underside of leaves and leaf axils (crotches). Shake frequently to keep the blend emulsified. Spray at 2 week intervals. Use it all or discard any remaining when you've finished spraying.
I've seen numerous formulas suggesting Neem, with warm water and detergent soap. No alcohol.
Any ideas about what the alcohol adds to the formula? Kills the bugs maybe with the Neem acting long term..?
