Cormoran is a package mix of an insect growth regulator and a neonicotinoid insecticide. It has contact and ingestion activity. Use enough water to obtain good coverage when applied by air or ground. Don’t exceed 0.25-inch water with chemigation. A repeat application 7-14 days after the first may be needed to maintain control.
Don’t apply Cormoran or other neonicotinoid insecticides (Group 4A) if one was applied at planting or at hilling. Make only two consecutive applications of Cormoran to foliage before rotating to a different MOA. Pay attention to max use rates for both novaluron and acetamiprid products.

| Colorado Potato Beetle | 6-12 fl oz | 12 h | 14 d | 15, 4A | E | Apply at 50% eggs hatch when larvae are small. Don’t apply to successive generations of CPB. |
| Potato Psyllid | 12 fl oz | 12 h | 14 d | 15, 4A | G (n+a) | Apply when eggs are hatching/nymphs are present. It should control all life stages. |
