PRODUCT INFORMATION

FortiTRI Herbicide (henceforth in this label referred to as FortiTRI) is a selective residual pre-emergence herbicide for controlling most annual grass weeds, annual broadleaf weeds, and sedges in field corn, popcorn, and processing sweet corn (refer to Table 1 for a list of weeds controlled pre-emergence). Residual pre-emergence application of FortiTRI must be activated by at least 1/2 inch of rainfall or sprinkler irrigation before weed seedling emergence. When FortiTRI is not activated, a labeled post-emergence herbicide or cultivation may be needed to control weed escapes. FortiTRI also provides contact burndown of many broadleaf weeds (refer to Table 2 for a list of weeds controlled by a burndown application). An adjuvant (refer to Additives section for details) is required with FortiTRI for optimum broadleaf burndown activity. Burndown application of FortiTRI must be made when broadleaf weeds are small and actively growing. Burndown activity may be slowed or reduced under cloudy and/or foggy or cooler weather conditions, or when weeds are growing under drought or other stress conditions. When targeting dense weed populations and/or larger broadleaf weeds, use higher spray volumes. Angling nozzles forward (to 45 degrees) may improve penetration of denser weed canopies.

Mode of Action

FortiTRI Herbicide contains three active herbicide ingredients. Saflufenacil is a potent inhibitor of protoporphyrinogen oxidase belonging to herbicide mode-of-action Group 14 (WSSA)/Group E (HRAC). Dimethenamid-P is a chloroacetamide belonging to the herbicide mode-of-action Group 15 (WSSA)/Group K3 (HRAC). Pyroxasul- fone is a potent inhibitor of very long chain fatty acid (VLCFA) synthesis, also belonging to herbicide mode-of-action Group 15 (WSSA)/Group K3 (HRAC). Saflufenacil is rapidly absorbed by roots and foliage. Following inhibition of the protoporphyrinogen oxidase, plant death is the result of membrane damage. Under active growing conditions, susceptible emerging weed seedlings usually develop chlorotic and necrotic injury symptoms within hours and die within a few days. Susceptible germi- nating weed seeds usually die as they reach the soil surface or shortly after emergence. Dimethenamid-P and pyroxasulfone are root-and-shoot inhibitors that control susceptible weed seedlings before or soon after they emerge from the soil.

Application Instructions

FortiTRI may be applied pre-plant surface, pre-plant incorporated, or pre-emergence to field corn, popcorn and processing sweet corn. Apply FortiTRI only before crop emergence.

Application Timing

FortiTRI may be applied pre-plant surface, pre-plant incorporated, pre-emergence, or in the fall. Refer to the Crop-specific Information section for specific application instructions (timings, rates, restrictions, and precautions) by crop.
