Lannate LV is mainly a contact insecticide. It also has ingestion activity, but its residues are short-lived. It may knockback some beneficial, predatory insects. It is probably best used late in the season to knockback multiple pest species. Adjust the spray solution pH to 5-7. Make only two consecutive applications before rotating to an insecticide with a different MOA. Similar products containing methomyl are available but use rates vary.

| Pest or Disease | MOA1 | Efficacy2 | Rate per Acre3 | REI4 | PHI5 | Notes |
| Aphid (various species) | 1A | F | 1.5-3.0 pt | 48 h | 6 d | It will knockback aphids. Products with longer residuals are preferred for controlling migratory aphids and limiting Potato Virus Y spread. Better for late season to knockback multiple pests. |
| Armyworms, Cutworms, Loopers (various genera, Lepidoptera) | 1A | G | 1.5-3.0 pt | 48 h | 6 d | Kills worms on contact for knockback control, but it may also knockback some beneficial, predatory insects. Apply when insects are active. |
| Beet Leafhopper (Circulifer tenellus) | 1A | P | 1.5-3.0 pt | 48 h | 6 d | It will control BLHs on contact but is not recommended for this pest because it provides only 5-7 days of residual control. Products with longer residual activity are more cost-effective for maintaining control of BLH during their migration periods and limiting spread of phytoplasma diseases (e.g., purple top). |
| Colorado Potato Beetle (Leptinotarsa decemlineata) | 1A | G | 1.5-3.0 pt | 48 h | 6 d | The label doesn’t mention CPBs, but applications made to target other pests will control beetles and larvae. It will also knockback some predator insects. |
| Lygus Bugs (Lygus species) | 1A | G | 1.5-3.0 pt | 48 h | 6 d | Kills lygus bugs on contact for knockback control, but it may also knockback some beneficial, predatory insects. Apply when nymphs are present for best results. |
| Potato Psyllid (Bactericera cockerelli) | 1A | F | See Label | 48 h | 6 d | The label doesn’t mention psyllids, but applications made to target other pests will knockback adult psyllids. It will also knockback some predatory insects. Products with longer residuals are preferred for controlling psyllids as they slowly migrate into potatoes. Better for late season to knockback multiple pests. |
| Thrips (Thripidae) | 1A | G | 1.5-3.0 pt | 48 h | 6 d | Kills thrips on contact for knockback control. It may also knockback some beneficial, predatory insects. Apply when thrips are active. |
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.
