Product Overview

Prime Source Imidacloprid 75 WSP Select is a systemic insecticide with both curative and preventative action that provides a long-lasting control on a wide range of pests such as white grubs, crane flies, and leafminers, mealybugs, and many more listed insect pests. The active ingredient has enough residual activity that applications can be made prior to the target pests' egg-laying activity. Can be applied to golf courses, sod farms, commercial, residential, industrial, and municipal turf areas, landscape ornamentals, and interior plantscapes. For easy tank mixing and measuring, the powder is packaged in compact water-soluble pouches.  Available in a bag of four 1.6-ounce packets.

*Please note:  This product is intended for large volume (20-50 + gallons) applications and would not be recommended for small residential applications.
