Proforce Duke 100WG is a selective sulfonylurea herbicide for post-emergent control of specified broadleaf weeds and grasses in turf, with suppression of Winter Grass and Bahia Grass. It works mainly through the foliage, so complete and even coverage of actively growing weeds is important.

For Control Of:

Bindii, Black Thistle, Cat’s Ear, Cotula, Cudweed, Guildford Grass, Medic, Mouse Ear Chickweed, Oxalis, White Clover, Onion Weed and False Onion Weed, plus Ryegrass. Suppresses Winter Grass and Bahia Grass.

How it Works:

The active ingredient inhibits ALS, disrupting susceptible weed growth. It is predominantly foliar and will not reliably control weeds that emerge after spraying.

When to Apply:

Apply to actively growing weeds and healthy turf under good growing conditions. Avoid treatment when weeds or turf are stressed.

How to Use:

Half-fill a clean spray tank with water, start agitation, add the measured granules and any specified wetting agent or crop oil, then finish filling. Maintain agitation and apply with calibrated equipment for complete, even coverage.

Application Rate:

Application rates and adjuvant requirements vary by target weed and turf species.

Active Constituents:

100g/kg iodosulfuron-methyl-sodium

Important:

• Do not leave mixed spray standing overnight
• Do not use carrier water below pH 5.5
• Follow the detailed sprayer clean-out procedure to protect other plants
• Wear elbow-length PVC gloves and goggles while preparing the spray
