Achieve quick knockdown and long-lasting residual control of a wide range of pests with TriStar®8.5 SL insecticide. The odorless, water-based formulation mixes easily and works with contact, systemic and translaminar activity to protect valuable plants. Plus, TriStar 8.5 SL is EPA classified as a reduced risk insecticide, is compatible with many fungicides and miticides, and can be used as an effective resistance management tool. It is a great alternative where pollination impact is a concern.


Start strong and finish stronger with Safari and TriStar – two key top performing insecticides your greenhouse can rely on.

Start with Safari drench/spray to control more insects faster and longer. Protect plants for a stronger finish with TriStar, which is also softer on beneficial insects and an alternative where pollinator impact is a concern. See our Bloom Brilliance brochure for helpful performance tips and trial data.


fall crop insect protection. 

Nufarm Technical Services Manager, Rick Fletcher presents strategies for effectively protecting fall greenhouse crops from yield-robbing insect damage.

This education session examines insect and disease control methods and best-fit tools, such as Safari and TriStar insecticides, to help crops start strong and finish stronger.




  • Provides contact, systemic and translaminar activity to penetrate and protect the old and new growth 
  • Absorbs and spreads within the plant to provide quick knockdown of a wide spectrum of insects (in as little as 15 min. as direct spray)
  • Up to 4 weeks residual control on bedding plants, 4 to 6 weeks on woody ornamentals and trees (depending on the plant material)


  • Excellent tank-mix partner
  • Compatible with most commonly used fungicides and miticides
  • TriStar is odorless and mixes easily with water


  • Good IPM and resistance management tool
  • EPA classified as a reduced risk insecticide 


For control of insect pests, apply either as foliar broadcast spray to obtain thorough and uniform spray coverage of the plants or via a basal bark or injection treatment. For foliar broadcast sprays, choose a finished spray volume appropriate for the size of the plants and amount of foliage which will provide thorough coverage throughout the canopy. For optimum control, allow at least 6 hours before overhead irrigation of foliage. Do not allow public use of treated area during application.

FOR FOLIAR BROADCAST SPRAYS: Mix TriStar® 8.5 SL with sufficient water and apply as a foliar spray to obtain thorough and uniform spray coverage of the plants. Choose a finished spray volume appropriate for the size of the plants and amount of foliage which will provide thorough coverage throughout the canopy. Apply as soon as insects reach treatment thresholds.

FOR BASAL BARK TREATMENT OF TREES (ornamental or non-bearing fruit or nut): Using a low pressure (10-25 PSI), small volume handcan or backpack sprayer, mix 12.5-25.3 oz of TriStar 8.5 SL per gallon of water with an organo-silicate adjuvant according to the adjuvant product instructions. One gallon should treat approximately 36-42 total inches of treatment DBH depending on bark surface. Do not apply to wet bark, during rainfall, or if rain is expected within 12 hours after application. Do not apply as a drench to the soil.

FOR TREE INJECTION APPLICATION (ornamental or non-bearing fruit or nut): Mix 9-12 milliliters (mL) of TriStar 8.5 SL per inch DBH of target tree in sufficient water for use following the manufacturer’s instructions for the specific injection device.
See label for complete directions for use.

TriStar 8.5 SL mixes quickly in water. This product has been found to be compatible with many commonly used surfactants, miticides and insecticides. Check physical compatibility using the correct proportion of products when combining products without prior history of use.

TriStar is absorbed quickly into the plant and withstands UV exposure longer than many competitors.


Do not make more than 4 applications per year.

Do not reapply more than once every 7 days. To determine if application is necessary, monitor pest densities. Consult local extension experts for thresholds.

Do not apply more than 25.3 ounces of TriStar 8.5 SL per acre in a single application.

Do not apply more than 92.5 ounces of TriStar 8.5 SL per acre per year.

Do not apply to bearing fruit trees.

See label for complete application rates and recommendations.
