Belay is a systemic neonicotinoid insecticide. It controls insect pests via ingestion. Expect 60-90 days of residual control depending on the rate used, soil and environmental conditions, application timing, and insect pressure. The following usage notes are for soil application only. There are several application options, including as a diluted spray onto seed-pieces, or in-furrow at planting, or as a spray over the row during hilling. Apply neonicotinoid insecticides (Group 4A) ONLY once in a season to limit the development of resistant insect populations.

| Pest or Disease | MOA1 | Efficacy2 | Rate per Acre3 | REI4 | PHI5 | Notes |
| Aphid (various species) | 4A | E | 9-12 fl oz | 12 h | It may work too slowly to prevent spread of Potato Virus Y, especially when winged (migratory) aphid numbers are high. | |
| Beet Leafhopper (Circulifer tenellus) | 4A | G | 9-12 fl oz | 12 h | Should provide some early season control, but it may work too slowly to prevent rapid spread of phytoplasma diseases (e.g., purple top disease) when BLH numbers are high. | |
| Colorado Potato Beetle (Leptinotarsa decemlineata) | 4A | E | 9-12 fl oz | 12 h | Don’t be alarmed to find newly emerged adult beetles alive on treated plants, because it can take days for them to start feeding, ingest the insecticide, and then die. But if larvae are found on treated plants, then the product residual is probably no longer active. | |
| Potato Psyllid (Bactericera cockerelli) | 4A | E (a) | 9-12 fl oz | 12 h | It should control migrating adult potato psyllids for 60-90 days. The application may be followed-up with in-season, foliar insecticides for a no-gaps psyllid management strategy. | |
| Wireworms (Elateridae) | 4A | P | 9-12 fl oz | 12 h | It can reduce wireworm damage to seed-pieces, but it will not prevent damage to daughter tubers during the growing season. | |
1Mode of action. NC = not classified..
2 Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
3 Rate per acre per application. Refer to the product label for maximum use rate per season.
4 Reentry interval.
5The minimum pre-harvest interval. Some products do not list PHI.
Note: always read and follow the directions on the pesticide label.
