Aza-Direct(azadirachtin)

General Information

Aza-Direct works via contact and ingestion. It has repellant and anti-feeding activity, and it interferes with molting. Does not kill adults. Make 2-3 applications every 7-10 days. Complete spray coverage is important. Spray mix pH should be 5 to 7, adjust if needed using an OMRI-approved buffering agent. Don’t combine with alkaline products or chemigate with irrigation water > pH 7. Similar products with azadirachtin are available but use rates vary.

Usage for Aza-Direct


Stage of Development: Emergence to Row Closure
Pest or Disease MOA1 Efficacy2 Rate per Acre3 REI4 PHI5 Notes
Aphid (various species) NCF-P1-3.5 pt4 h0 dApply when aphids first appear. 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.
Armyworms, Cutworms, Loopers (various genera, Lepidoptera) NCND1-3.5 pt4 h0 dApply when caterpillars are small. If needed, follow-up with 2-3 applications at 7-10 day intervals.
Beet Leafhopper (Circulifer tenellus) NCND1-3.5 pt4 h0 dApply when leafhoppers first appear. It may work too slowly to limit spread of phytoplasma diseases (e.g., purple top).
Colorado Potato Beetle (Leptinotarsa decemlineata) NCF1-3.5 pt4 h0 dApply at 30% egg hatch when larvae are very small. If needed, follow-up with 2-3 applications at 7-10 day intervals.
Lygus Bugs (Lygus species) NCND1-3.5 pt4 h0 dApply when nymphs are present.
Potato Psyllid (Bactericera cockerelli) NCF1-3.5 pt4 h0 dApply when adults psyllids are depositing eggs and/or when nymphs are present.

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.
