Professional Insect Growth Regulation for Ornamental Crops
Control troublesome immature insect stages with Adept® 25W Insect Growth Regulator from OHP. Adept is a 25% diflubenzuron insect growth regulator formulated for use on ornamental crops grown in greenhouses, shadehouses, and interiorscapes.
Unlike conventional contact insecticides, Adept works as an insect growth regulator by interfering with the development and molting process of susceptible insects. This makes it particularly useful as part of an integrated pest management program targeting fungus gnats, shore flies, and certain foliar-feeding pests.
The 1 lb. package contains 16 individual 1-oz. packets, making measuring and handling convenient for professional applications.

Active Ingredient
Diflubenzuron — 25.0%
Adept belongs to the benzoylurea insect growth regulator class and is classified as IRAC Group 15. Diflubenzuron interferes with insect development and molting, making it especially useful for targeting immature stages.
Target Pests
Adept 25W is labeled for use against or for suppression/control of susceptible pests including:
- Fungus gnats
- Shore flies
- Armyworms
- Lepidopterous leafminers
- Whiteflies
The effectiveness and labeled status can vary by crop, pest, and application method. Always consult the current product label for the complete pest list and approved uses.
Fungus Gnat & Shore Fly Management
Adept is particularly useful for managing fungus gnat and shore fly larvae in greenhouse production. Following application, initial control may take several days because Adept works through insect growth regulation rather than functioning as a conventional fast knockdown insecticide.
Under labeled conditions, Adept can provide 30 to 60 days of residual activity against fungus gnat larvae. It has no effect on adult insect stages, so proper timing and integrated pest management are important.
Application Methods
Depending on the crop, pest, and labeled use, Adept may be applied using methods including:
- Sprench
- Foliar spray
- Drench
The product is also labeled for certain applications under greenhouse benches and other non-crop areas. Application rates vary according to the specific pest and use site.
