Fortress Ornamental Herbicide bag (50 lb)

Fortress is a pre-emergent granular herbicide for control of weeds in nursery containers and field grown ornamentals. Formulated on the engineered Verge® granule, Fortress produces virtually no dust and low odor, resulting in improved worker safety and ease of application. Applicators are required to wear minimal Personal Protective Equipment (PPE) — long sleeved shirt, pants, water-proof gloves, and socks plus shoes. Fortress has a CAUTION signal word and a 12-hour REI.

Fortress controls a wide range of both grassy and broadleaf weeds by creating a barrier in the soil. Fortress works by inhibiting cell division and disrupting cell wall formation in roots and shoots of emerging weed seedlings. Irrigate new plantings before Fortress application with ½in. water to ensure settled and firm soil around the root system. For best results, apply Fortress prior to rainfall or irrigate with approximately ½in. of water. Broadcast Fortress uniformly over ornamental containers or field soil at the rate of 150 lbs./acre. To prevent weed escapes, do not disturb the soil or media in Fortress treated areas; this will disrupt the herbicidal barrier necessary for successful weed control.
