|A word of caution about applying oils - whether they be neem, cooking
oil, Sun Ultrafine Horticultural oil, or even the carrier oils in some
insecticides (like Orthenex or Isotox):
Apply oils only when the plants are cool to the touch.
I highly recommend early morning application, before solar heating of plant tissues takes place, as if oils are applied to plants that are quite warm, one can see the loss of inflorescences and leaf burning. (I spoke to a woman in Florida who ran a small business like mine, but she was only able to spray when getting home from her "real job" in the early evening, and she wiped out every flower spike on her huge collection of vandaceous plants.)
I don't know if it's correct or not, but I liken it to the use of baby oil as a suntan expediter.
