Onager works via contact activity. Controls eggs and immature life stages. It is translaminar, but not systemic. Good coverage is essential. Use a horticultural grade oil adjuvant. Apply with enough water to obtain thorough coverage via ground or aerial. Chemigate at 100% travel speed or use only 0.1 to 0.15-inch water with Onager at 24 oz/A. Make only one application per season. Onager Optek has enhanced leaf coverage vs. Onager.

| Potato Psyllid (Bactericera cockerelli) | 10A | G (n) | 16 to 24 fl oz | 12 h | 21 d | Apply to control psyllid eggs and nymphs. Translaminar, so it should control nymphs on the underside of leaves. It will not control adults. |
| Two-spotted Spider Mite (Tetranychus urticae) | 10A | G | 16 to 24 fl oz | 12 h | 21 d | Apply at the first sign of mites i.e., apply early in the outbreak cycle. Controls mites via activity on eggs and immatures; it will not control adults, but they won’t lay viable eggs. |
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.
