Applications & Uses
- Markets
- Applications
- Applicable Crop
- Mode Of Action
Fortress provides weed control by combining two modes of action, inhibition of both cellulose biosynthesis (MOA 21) and microtube assembly (MOA 3). These MOAs result in the inhibition of cell wall formation and mitotic processes in shoots and roots of emerging seedling weeds. The result is the prevention of weed seed emergence.
- Use Sites
Fortress is registered for use in field and container ornamentals.
- Application Rates
Apply Fortress herbicide at the rate of 150 lbs. per acre.

Technical Details & Test Data
- Treatment
Treatment of ornamental species not listed on the label for Fortress
The species listed in the table aside have been tested under actual growing conditions and found tolerant at the recommended application rate. Users who wish to use Fortress on ornamental plant species not listed on the label may determine the suitability for use by treating a small number of such plants at the recommended rate. The user assumes responsibility for any plant damage or other liability resulting from use of Fortress on plant species not recommended on the label. Fortress has shown excellent grassy and broadleaf weed control in a number university tests. It is particularly good on crabgrass, bittercress and spurge, among other hard to control weeds. Shown in Fig.1 are 2017 test results from Dr. Andy Senesac, Cornell University. It shows the percent weed control at 30, 60 or 90 days after treatment respectively
Injury on the following plant species has been observed following applications of Fortress and use is not recommended.
- Ajuga spp. bugleweed or ajuga
- Brassica spp. mustard
- Euonymus alatus ‘Compactus’ dwarf burning bush
- Euphorbia spp. spurge
- Hydrangea spp. hydrangea
- Iberis spp. candytuft
- Juniperus horizontalis ‘Prince of Wales’ Prince of Wales juniper
- Melaleuca quinquenervia cajeput tree

HAZARDS TO HUMANS AND DOMESTIC ANIMALS
CAUTION
Harmful if absorbed through skin or inhaled. Causes moderate eye irritation. Avoid contact with skin, eyes, or clothing. Avoid breathing dust. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, using tobacco, or using the toilet. Remove and wash contaminated clothing before reuse.
- User Safety Recommendations
- Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing
- Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.
- Environmental Hazards
This product is toxic to fish and highly toxic to other aquatic organisms including oysters and shrimp. Use with care when applying to turf areas adjacent to any body of water. Drift and runoff from treated turf may adversely affect aquatic organisms in adjacent aquatic sites. Do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not apply when weather conditions favor drift from treated areas. Do not contaminate water when disposing of equipment washwaters.
Groundwater Advisory: This pesticide has properties and characteristics associated with chemicals detected in ground water. This chemical may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow.
Surface Water Advisory: This pesticide may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soil and soils with shallow groundwater. This product is classified as having a high potential for reaching surface water via runoff for several months or more after application. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of isoxaben from run off water and sediment
