If you are applying an insecticide such as Suspend SC to the point of dripping or runoff, then you are likely using too much product. This could cause you to go over the labeled rates for legal and safe application. If you are treating on ornamental plants, then you want to get thorough coverage without runoff; runoff would mean that the product is falling off the leaf surface rather than staying on it and drying there to protect from your target insects.
The Suspend SC can be used 0.25 - 1.50 oz. per gallon of water. 1 Gallon of finished solution will generally cover 1,000 square feet when using a hand pump sprayer for spot or perimeter treatments. The pint of the Suspend SC can treat approximately 16,000 squeare feet.
The best way to dispose of leftover mixed Suspend SC is to pour along the foundation of the home outside.
