Be sure to review the full product label regarding crop rotation and use of manure on other sites.

Per the GrazonNext HL Herbicide product label for Seeding grasses:
Preemergence: Grasses may be reseeded in the fall following an application of GrazonNext HL applied in the spring or early summer.
Postemergence: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development.
GrazonNext HL Herbicide will kill sweet and white clover as well as horsenettle. It would not selectively kill the nettle and not the clover.
GrazonNext should only be used on pastures and other areas approved on the product label, not on residential lawns.

Per the product label for GrazonNext HL Herbicide
Preemergence: Grasses may be reseeded in the fall following an application of GrazonNext HL applied in the spring or early summer.
Postemergence: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development. GrazonNext HL may suppress certain established grasses, such as smooth bromegrass (Bromus inermis), especially when plants are stressed by adverse environmental conditions. Plants should recover from this transient suppression with the onset of environmental conditions favorable to grass growth and upon release from weed competition
