The abamectin in Minecto Pro is not very effective for aphids. | |
| spirotetramat (Movento HL) | 2.0-2.5 fl oz | 5 fl oz | 24 h | 7 d | 23 | E-G | Apply before populations build, or about 10 days before an earlier systemic insecticide breaks down.

F-P
Notes
Apply before aphids are present in large numbers if the goal is to keep aphid numbers in check and virus spread is not a concern. Apply when aphids first appear to limit virus spread, however it may work too slowly to limit spread of Potato Virus Y, especially when winged (migratory) aphid numbers are high. Does not provide immediate mortality.
