Like Bonide, this is another systemic pesticide option that will stick with your plant for an extended period of time and kill multiple generations of pests, should their be eggs that hatch at a later date. From the manufacturer:
Promis, Aphid, Thrip and White Fly Killer dissolved in water and applied to soil is absorbed by the roots. Once absorbed, it moves through the entire plant to protect against insects. This product also moves into and protects new growth after application. To control insects, the insecticide must distribute completely throughout the plant. Rain or water cannot wash off Promis inside the plant. See plant specific restrictions for pre-harvest interval. If no pre-harvest interval is listed, then product may be applied up to and including day of harvest.
