General info on lady of the night.
While there are a number of plants that actually share this common name, I am assuming you are referring to the night-blooming flowering shrub. Here is more information: http://mgonline.com/articles/ladyofthenight.aspx
I have used a pesticide to try to cure it but the new leaves are curled up and have white spots on them
There are several plants called Lady of the Night, but I am assuming you have night blooming jasmine. Try Neem oil, it is safer and should take care of an insect or fungus.
