Canola as a horticultural oil


Here is an item I would like to throw out for comment:

Canola oil is mentioned as being a useful horticultural oil, for example:
http://ipmofalaska.homestead.com/files/hortoils.html

If so, could one not use a product such as Pam Cooking Spray (essentially Canola oil with propellant) for spot treatment of infested plants? Of course, one should always test on a particular plant, but I have tried this on a Brugmansia with white flies with apparent success and no leaf damage.

Is this beginner's luck? Questions? Comments? Snide remarks? (yes, I know, don't use Garlic flavored Pam)
