Actara has contact and ingestion activity. Translaminar and foliar systemic (moves to new leaves, but not downward). A spray adjuvant may improve coverage for ground or aerial application. Don’t use stickers. Chemigation may be best when the canopy is dense; use 0.2-inch water or less and the highest allowed rate. Don’t apply Actara or other neonicotinoid insecticides (Group 4A) if one was applied at planting or at hilling. Make only two consecutive in-season, foliar applications of Actara.

| Target | Application per Acre | REI | PHI | MOA | Eff. | Notes |
|---|---|---|---|---|---|---|
| Aphid | 3 oz | 12 h | 14 d | 4A | E | Apply when aphids are first detected. |
| Beet Leafhopper | 1.5-3 oz | 12 h | 14 d | 4A | E | Apply when BLHs are present to minimize spread of phytoplasma diseases (e.g., purple top). |
| Colorado Potato Beetle | 1.5-3 oz | 12 h | 14 d | 4A | E | Apply when about 50% of the eggs have hatched larvae are small. |
| Potato Psyllid | 1.5-3 oz | 12 h | 14 d | 4A | G (a) | The label does not mention potato psyllids, but applications targeting other pests can control them. Apply when adult psyllids are migrating into the field. |
