Delegate WG(spinetoram)

General Information

Delegate WG works via contact and ingestion activity. It is translaminar but not systemic. Repeat applications may be needed for heavy infestations. An acidic spray solution will significantly shorten residual activity, so adjust to pH to 5 to 9. Ground, aerial, or chemigation. Make only two consecutive applications of Group 5 insecticides (spinetoram and spinosad) before rotating to an insecticide with a different MOA. Don’t apply to consecutive generations of CPB. Another product, Radiant SC, has the same active ingredient but is a different formulation.

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.
