Sefina works mainly via ingestion. Anti-feeding activity. Translaminar. Thorough spray coverage is essential. Use enough water to obtain good coverage when applied by air or ground. Don’t exceed 0.25-inch water with chemigation. Minimum interval between treatments is 7-days. Make only two consecutive applications before rotating to an insecticide with different MOA.Translaminar.

| Aphid (various species) | 9D | E | 3 fl oz | 12 h | 7 d | Apply at the first sign of aphids. Anti-feeding activity should limit spread of potato viruses. |
| Potato Psyllid (Bactericera cockerelli) | 9D | G (n+a) | 14 fl oz | 12 h | 7 d | Apply when adults are migrating into the field, especially if they are depositing eggs. Rapid anti-feeding activity will also help to limit spread of zebra chip disease. Controls all life stages. Translaminar, so it will control nymphs on the underside of leaves. |
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.
