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.
