Ornamental herbicide

Fuerte is a pre-emergent granular herbicide for control of weeds in field, container and landscape ornamentals, grounds maintenance, and non-cropland areas. Also for Christmas Tree Farms and conifer farms and other label specified non-crop areas.


Fuerte contains the active ingredients flumioxazin and prodiamine formulated on the Verge® granule. The engineered granule provides an unprecedented level of dust reduction resulting in improved worker safety and ease of application. Fuerte applicators are required to wear minimal Personal Protective Equipment (PPE) of long-sleeved shirt and long pants, waterproof gloves, socks and shoes. Fuerte has a CAUTION label with a 12-hour REI.


Fuerte provides control of a wide range of problem grass and broadleaf weeds by creating a barrier in the soil and is active for several months. Fuerte contains the active ingredient flumioxazin, which is a protoporphyrinogen oxidase inhibitor (PPO) mode of action (Group 14) and prodiamine, a member of the dinitroanilines family of herbicides (Group 3) that inhibits the steps involved with cell division. The active ingredients control susceptible weeds by preventing growth and development of newly germinated seeds. Fuerte will not control established weeds.


Irrigate new plantings before Fuerte application with ½" water to ensure firm and settled soil media around the root system. Broadcast Fuerte uniformly over ornamental containers or field soil at the rate of 100 lbs./acre. Fuerte should be applied when rain is soon forecasted or watered in with approximately ½" of water soon after application. Fuerte should be broadcast evenly over media for maximum performance. To prevent weed escapes, do not disturb the soil or media in Fuerte treated areas; this will disrupt the barrier necessary for successful weed control.
