No. Neem seed oil isnt' a sufficant like dormant and solar oils. It's
highly diluted and should be mixed with a sticking agent--vegetable oil or
dish soap. Of course, you want to apply it in early morning or late in the
evening, because anything will burn in the mid-day sun. I never had a
problem with it in Texas, and our sun was blazing. One of the biggest
commercial antique rose growers (Antique Rose Emporium in Brenhan, TX) uses
it on all their fields. And, many soy and cotton farmers in Texas have crop
dusters apply it to their fields--in the early morning hours! Hope this
helps.
