Admire Pro is a systemic neonicotinoid insecticide. It moves upward to new growth, but not down. It has several application options, including as a diluted spray onto seed-pieces, as an in-furrow spray or a subsurface side-dress on both sides of the hill, or as an early foliar application. Apply neonicotinoid insecticides (Group 4A) ONLY once in a season, because exposure to insecticides with long persistence in foliage can create strong selection pressure towards resistant insect populations. Similar products (other brands) containing imidacloprid are available but uses and use rates vary.
The foliar application rate is quite low, so the residual effect of Admire Pro applied to foliage is significantly shorter compared to seed treatment or soil application, which are the more common ways to apply this product.
Usage for imidacloprid on Potatoes
Emergence to Row Closure
| Target | Application per Acre | REI | PHI | MOA | Eff. | Notes |
|---|---|---|---|---|---|---|
| Aphid | 1.3 fl oz | 12 h | 7 d | 4A | G | Apply to foliage when aphids are first detected. Expect shorter residual activity compared to seed treatment or soil application of Admire Pro. |
| Beet Leafhopper | 1.3 fl oz | 12 h | 7 d | 4A | G-F | Apply to foliage when BLHs are present to minimize spread of phytoplasma diseases (e.g., purple top). |
| Colorado Potato Beetle | 1.3 fl oz | 12 h | 7 d | 4A | G | Apply to foliage when about 50% of the eggs have hatched larvae are small. |
| Potato Psyllid | 1.3 fl oz | 12 h | 7 d | 4A | G (a) | Apply to foliage when adult potato psyllids are migrating. |
