Active ingredient is Spinosad A & D. the new generation BT. While not specifically designed for Colorado Potato Beetle, it works better than anything we have tried. Spinosad works so well on CPB that many chemical companies market it to conventional growers under a different name even though it is a 100% organic OMRI listed product. Wide label that includes CPB, codling moth, army worms, loopers, moths, corn borers, thrips, caterpillars, beetles and many more. Can use up to one day prior to harvest on vegetables, fruit trees, lawns and ornamentals. Rate 2 oz per gallon of water.
