Neem Solutions-Stability
This question concerns the use of Neem oil as an insecticide. Do solutions
of Neem (made from say the Dynagrow oil with soap) have to be used within a few hours, or can the solutions be made up and used over a period of time? What about Neem oil itself. Does it lose its effectiveness if stored at room temp conditions? Thanks Charles VanDyke |

Neem Solutions-Stability
Hi, Chuck.
Neem oil is stable if kept cool and dark, but the active ingredient, azadirachtin, degrades with light and heat. Emulsifying it in soapy water - by itself - does nothing to change that, but if you consider that a diluted dispersion will let more light penetrate into itself easier, I guess the degradation would be hastened. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info!
