Vexis Herbicide Granular

Vexis Herbicide Granular

Vexis Herbicide Granular comes in an easy-to-use granular formulation that reduces drift or off-target application and may be applied to both dry and wet turf. For best results water in Vexis within 24 hours. After two weeks of application, targeted sedge is dead.

For control of sedges, apply Vexis herbicide in late spring and early summer before the plant matures and produces additional tubers. Repeat applications over multiple growing seasons may be required to achieve effective chemical control.

Active Ingredient-Pyrimisulfan 0.025%

Pyrimisulfan works as an ALS inhibitor in the sulfonanilide chemical class. It inhibits an enzyme in the biosynthesis of amino acids. Research shows that it may have activity against weeds that have developed resistance to other ALS-inhibiting heribices.

Turf Safety

Vexis Herbicide Granular is safe on both cool and warm established season turfs, including bentgrass (mowed at 0.50") and improved varieties of St. Augustine including floratam and bitterblue. See label for the list of turfs.

Packaging and Yield

• Apply 2 lb of product per 500 sq.ft. (174 lb of product per acre).
• 15 lb bag treats 3750 sq ft at the rate of 2 lb per 500 sq ft

When to Apply:

• Apply when weeds are actively growing. Retreatment may be necessary when weed pressures are high, when soil moisture is low, or when weeds are not actively growing.
• To avoid injury to improved varieties of St. Augustinegrass or Centipedegrass, apply when night-time temperatures are above 50°F for 7 consecutive nights.
• Wait to reseed or resod until after 21 days following application.

Application Tips:

• Moisture on leaf surface is not required.
• Apply when weed leaves are wet or dry.
• Temperatures below 50°F will reduce weed control activity.
• For best results, water-in granules within 48 hours after treatment.
• For best results, postpone mowing until granules are watered-in.
• For best winter annual control (henbit, false dandelion, and chickweed) apply in early fall.
