Unique dual powered post-emergent Sulfonylurea herbicide for grassy and tough broadleaf weed control in established warm season turfgrass. Sulfonylurea herbicides are effective at rates 1-5% of other herbicides.

Quali-Pro® NEGATE 37WG contains Rimsulfuron and Metsulfuron-Methyl herbicides which belong to the sulfonylurea chemical family of herbicides. Herbicides in this family inhibit branched-chain amino acid synthesis in plants. Quali-Pro® NEGATE 37WG is absorbed through foliage of plants, rapidly inhibiting the growth of susceptible weeds. 1-3 weeks after post emergence application to weeds, leaves of susceptible plants appear chlorotic, and the growing point subsequently dies. In warm, moist conditions, the expression of herbicide symptoms is accelerated; in cold, dry conditions, expression of herbicide symptoms is delayed. Death of leaf tissue and growing point will follow in some species, while others will remain green but stunted and noncompetitive.

Active Ingredients:

  • Methyl 2
  • Rimsulfuron

For Use On: Non-Residential Bermudagrass and Zoysiagrass Only.

Best weed control is attained when Quali-Pro® NEGATE 37WG is applied in vigorously growing weeds or desired plants. The herbicidal action of Quali-Pro® NEGATE 37WG may be less effective on weeds stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, weeds hardened-off by drought stress are less susceptible to Quali-Pro® NEGATE 37WG. Post emergence weed control may be reduced if rainfall occurs soon after application. It is necessary for the spray material to dry on the foliage to be sufficiently absorbed (generally Quali-Pro® NEGATE 37WG is rainfast in 4 HRS).

Dormant and non-dormant turf:

Apply 1.5 OZ/ACRE for weed control. Some chlorosis of the turf may occur following application.

Bermudagrass and Zoysiagrass:

Apply 1.5 OZ/ACRE for weed control. Some chlorosis or stunting of the turfgrass may occur following application.

Bahiagrass Control:

For the selective control of Bahiagrass in Bermudagrass turf, use 1.5 OZ/ACRE. Apply a repeat treatment in 4-6 weeks if necessary. Some chlorosis or stunting of the Bermudagrass may occur following the application.


Addition of a nonionic surfactant of at least 80% active ingredient at 0.25% by volume (1 QT/100 GAL) provides maximum performance, but may temporarily increase chlorosis of the turf. When an adjuvant is to be used with this product, Control Solutions, Inc. suggests the use of a Chemical Producers and Distributors Association certified adjuvant. Products must contain only EPA-exempt ingredients.
