Try a systemic like Bonide (I use the granules) or Beyer's 3 in 1. The Beyer's in a liquid so you can use it as a spray and water wih it.
But whatever you decide to spray, just use one. Using multiple pesticides usually just ends in the death of the plant. If you want to switch to a new plan of attack, rinse the old stuff off then give the plant some recovery time.
