Prodiamine 4L (Quali-Pro)

Prodiamine 4L is a selective preemergence herbicide for control of grass and broadleaf weeds in established turfgrasses (excluding golf course putting greens), lawns and sod, nurseries, ornamentals, hardwood seedling nurseries, Christmas tree farms. Quali-Pro Prodiamine 4L is used for pre-emergent control of grasses and broadleaf weeds. Each gallon contains 4 pounds active ingredient. The active ingredient inhibits mitotic processes in plants and controls susceptible weeds by preventing growth and development of newly germinated weeds. Weed control is most effective when Prodiamine 4L is activated by at least 0.5 inches of rainfall or irrigation or shallow incorporation (1 to 2 inches for non-turf applications) before weed seeds germinate and within 14 days following application.
