Re: Canola as a horticultural oil

Well Don,
Interestingly another list I belong to about Orchids has had a thread going
on oils ( from Canola to almost motor oil :>} ).  The general opinion is
that damage to plants occurred when an oil is sprayed on when the plant is
to hot, such as mid-day. Everyone suggested spraying in the later evening or
the early morning,  Also it was mentioned that even Nem oil will cause
damage if applied when hot.
I plan to try Pam on a couple of plants late in the day then rinse them off
during the morning watering.
Seems like a good idea to me and Costco sells Pam for a song.

I was beginning to think that my query was being regarded as something from Jerry Baker show! Yes, there are certainly caveats. Don't spray in too much heat/sunlight. And of course, don't spray so heavily that the propellant in the mixture (not specified on the label) might cause leaf or shoot damage.

Another question. If you emulsify the horticultural oil with detergent, does it lose its effectiveness?
