Stop overhead watering, or watering in the evening.

Bayer All in One a granular product, that you spread on the ground and is drawn up into the foliage. It contains fertilizer, a fungicide and pesitcide to keep away the common pests like aphids. It's less messy than powders, and easier to apply than sprays, too.
