Hi Bonnie. You are most welcome. I have discovered that it is often of more value to post the link to good info rather than try to paraphrase the info. It may well have been a typo in the original recipe posted, so I wanted to make sure you had other info also.
Are you familiar with Horticultural Oils such as Neem? One of the cautions for them is to watch the temperature when you spray. High temps can fry a sprayed plant. Here is some info for you. (just so you understand the application and efficacy of oil on plants)

Again, glad to help.
