Southern Ag Parafine Horticultural Oil does not list that it can be used on trees so there is not a rate we can advise on, we do apologize. We would recommend reaching out to the manufacturer directly to confirm, they can be reached at (941) 722-3285.
The Southern Ag Parafine Horticultural Oil is diluted with water and applied as a spray on the plants you need to treat using a handheld or backpack sprayer. Be sure to cover all leaf and stem surfaces thoroughly for best results.
