Gain control over indoor and outdoor pests with TriStar 8.5 SL insecticide. It targets a range of annoying plant-harming insects such as aphids and leaf miners and provides total control for as many as six weeks. It has a 12-hour re-entry interval for plant houses and works effectively with both miticides and fungicides. 

How TriStar 8.5 SL Insecticide Works

TriStar 8.5 SL insecticide contains acetamiprid as the active ingredient. This odorless, organic compound targets leaf-sucking insects and plant-damaging larvae such as the fruit fly. It works by interrupting the insect's brain signals and causing excitement within 30 minutes. Afterward, the ingredient leads to paralysis in the target pest and finally kills it. It starts working upon ingestion and may affect certain pests upon contact. TriStar 8.5 SL targets all life stages of the insect, from the eggs and the larvae to the adults themselves.

Where to Use TriStar 8.5 Insecticide

Use TriStar 8.5 SL insecticide both indoors and outdoors where flying and plant-sucking insects thrive. It's useful for fighting aphid infestations in greenhouses and killing mealy bugs on outdoor flowering plants. Though it's useful for knocking out pests on nonbearing fruit trees, never apply it to bearing fruit and nut trees at home or in commercial orchards. Some other places for use include:

  • Bedding plants
  • Indoor and outdoor residential and commercial spaces
  • Lathhouses
  • Nonbearing fruit and nut trees
  • Ornamental trees
  • Potted flowering plants
  • Shade houses

Target Pests

TriStar 8.5 SL insecticide controls many different insect pests indoors and outdoors. With one application, aphids and crane fly larvae don't stand a chance against the active ingredient. It kills psyllids and sawflies and prevents weevils from harming greenhouse plants. Other target pests include:

  • Adelgids
  • Caterpillars
  • Fungus gnat larvae
  • Plant bugs
  • Thrips
  • Whiteflies

TriStar 8.5 SL Insecticide Provides Long-Lasting Control

It only takes one application for TriStar 8.5 SL insecticide to control numerous pest insects for up to six weeks. It works in greenhouses and plant nurseries as well as on commercial and residential plant beds and ornamental trees. TriStar 8.5 SL combines well in the tank when it's used with miticides and other pesticides for complete pest control.
