Product Overview

Ascertain TR is a powerful insecticide that shields containerized plants, ornamentals, and other non-food crops in greenhouses. Its total release application distributes billions of micron-sized particles that covers 3,000 sq. feet in just a few minutes. This easy-to-use insecticide contains an active ingredient that quickly kills pests by contact and feeding activity. Controls wide-range of insects like fungus gnats, caterpillars, bagworms, armyworms, and mites, making it an effective first line of defense in greenhouses. For health safety, it has a 12-hour restricted entry interval and also assures the safety of greenhouse plants, including open blooms. With normal air circulation, equal coverage at the top and bottom of leaf surfaces can be achieved. Can be used rotationally with other Atticus total release insecticides and best alternative to Attain TR. Comes in a 2 fl. oz. bottle.

Mode of Action:

The active ingredient in this product, bifenthrin, is a member of the class of insecticides known as pyrethroids (Group 3A). This product is effectively introduced to the insect by contact and feeding activity.

Resistance Management:

For resistance management, Ascertain TR contains a Group 3A insecticide. Any insect population may contain individuals naturally resistant to Ascertain TR and other Group 3A insecticides. The resistant individuals may dominate the insect population if this group of insecticides is used repeatedly in the same greenhouse. Appropriate resistance-management strategies should be followed. To delay insecticide resistance, take the following steps:

  • Rotate the use of Ascertain TR or other Group 3A insecticides within a growing season, or among growing seasons, with different groups that control the same pests. DO NOT make more than two (2) consecutive applications of this product before rotating to a chemical with a different mode of action.
  • DO NOT make sequential applications to crops unless applied in combination with other effective insecticides with a different mode of action.
  •  DO NOT reapply product within 48 hours of a previous application.
  •  Adopt an integrated pest management program for insecticide use that includes scouting, uses historical information related to pesticide use, crop rotation, record keeping, and which considers cultural, biological and other chemical control practices.
  • Monitor after application for unexpected target pest survival. If the level of survival suggests the presence of resistance, consult with your local university specialist or certified pest control advisor.
  • Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area. Report any incidence of non-performance of this product against a particular insect species to you Atticus, LLC representative. If resistance is suspected, treat resistant insects with an insecticide having a different mode of action or use non-chemical means to remove insects, as practical.

Preapplication Directions:

Apply this product when pest or damage typical of indicated pest is observed. Shut off all exhaust fans and close all windows, doors land ventilators. DO NOT place within 10 horizontal feet of any ignition sources such as pilot lights (shut off gas valves), other open flames or running electrical appliances that cycle off and on. Prepare a 3-foot plant-free zone in which to place container. Elevate the container so that the top of the can is above the top of the plant canopy. Make sure the spray is unobstructed by foliage or other physical objects in order to obtain the maximum distribution of the product. Common practice is to place the container on a stool or overturned pot to elevate it to allow for unobstructed release to treat hanging baskets, an empty basket can be used to hold the container and elevate it to the hanging basket level. Low volume horizontal air flow may help optimize performance. Apply when foliage is dry and greenhouse temperature is between 60°F to 80°F. Keep container at room temperature (about 65°F). Prior to a full-scale application, run a small-scale test and observe for plant damage and performance. See Plant Safety Information for more details. All human and animal occupants of the greenhouse must be removed before treatment. The greenhouse must be ventilated according to the requirements of the Worker Protection Standard before reentry.


Thorough coverage is achieved by the normal air movement within a greenhouse. The chemical will move around and throughout the plant foliage due to the small particle size produced and the normal ebb and flow movement of the air. Both top and bottom of the plant foliage are covered with particles during application. DO NOT use in small, enclosed spaces such as closets, cabinets or under counters or tables. Use of a Total Release container in an enclosed space may cause it to explode, resulting in injury to people or damage to property. Use one 2 ounce container per 3,000 square feet (50,000 cubic feet). For greenhouses with tough to control insects, 2 containers per 3,000 square feet (50,000 cubic feet) is permissible. For smaller greenhouse spaces (less than 3,000 square feet), use one container. Depending on the severity of the insect infestation, the product can be applied 1 to 2 times per week.

To Activate Containers:

Hold the container facing away from the body and depress the actuator until it is locked down. Place the container in the plant-free zone and quickly leave the treatment area. If activating more than one container in the treatment area, begin at the end farthest from the door, and place containers as the applicator moves towards the exit door. Once all containers have been activated, immediately leave the treatment area and close the door.

Plant Safety Information:

The phytotoxic potential of this product has been assessed on a wide variety of common ornamental plants with no phytotoxicity observed. Not all plant species, varieties, and cultivars have been tested for tolerance to this product or pesticide treatments preceding or following those of this product.

Local conditions can also influence plant tolerance and may not match those under which this product has been tested. Test the product on a sample of the plants to be treated to ensure that a phytotoxic response will not occur prior to large-scale use. Because many cultivars within a plant species vary in tolerance to chemical applications and growing conditions, the grower must recognize these differences and test the product accordingly. At a minimum, always test a small group of representative plants for tolerance to this product under local growing conditions and before large-scale use. Grower assumes responsibility for testing species suitability under local growing conditions by treating a small number of plants at the specifies rate. At a minimum, this should include evaluating treated plants for several weeks following treatment for possible injury or other effects. To the extent consistent with applicable law, by applying this product, the user assumes responsibility for any crop damage or other liability associated with factors beyond the manufacturer's control, such as weather, the presence of other materialism and manner or use of the application. Follow all restrictions and limitations in this label.
