Chlorsulfuron 75 WG Herbicide

Chlorsulfuron 75 WG, manufactured by Alligare, is a pre-and post-emergent herbicide designed to control grassy and broadleaf weeds in various sites. It performs exceptionally well in controlling perennial and annual weeds that repeatedly like to grow on lands.

It works systemically, moving through the plants' roots and foliage to inhibit the growth of problem weeds. The product is a wettable granule that is easy to mix and apply.

Tools Needed

You will need to mix the product into a sprayer of your choosing, such as a backpack sprayer, hand pump sprayer, or a professional spray rig for large applications.

How to Use

• Step 1: Determine how much Chlorsufuron 75 WG you need by measuring the square footage of the treatment area. To do this, measure the treatment area's length and width in feet, then multiply them together (length x width = square footage). To get acreage, take the square footage and divide it by 43,560 (square footage / 43,560 sq. ft. = acres). Typically, this product is mixed at a rate of 1-3 ounces per 100 gallons not to exceed the maximum of 3 ounces per acre. For small spot applications, mix 1 gram of Chlorsulfuron 75 and a surfactant like Alligare 90 (0.33 oz per gallon) in 1 gallon of water.
• Step 2: Fill the sprayer with freshwater 1/4 to 1/3 of the way full. Begin agitation and then add the appropriate amount of Alligare Chlorsulfuron 75. Fill the tank with the remaining water. Agitate the sprayer until the solution is well-mixed, and then add the necessary amount of spray adjuvants.
• Step 3: Spray the target weed, ensuring even coverage via a fan spray setting. Check back after 2 weeks and reapply if necessary to get complete control.

Where to Use

Use Chlorsulfuron 75 WG can be used on pastures, ranges, Conservation Reserve Program (CRP) lands, and non-crop industrial sites (including industrial (unimproved) turf and for growth suppression and seedhead inhibition of established desirable grasses). Some non-crop industrial sites include airports, fence rows, government, and private lands, military installations, petroleum tank farms, pipeline and utility rights-of-way, plant sites, pumping installations, railroads, roadsides, and associated rights-of-way, storage areas, and other non-crop areas where you would like weeds to be controlled.

When to Use

Use this product when you notice weed growth. Spraying works best when the soil is moist and weeds are actively growing. To suppress the growth of seedheads time your applications during green-up and before seed-heads emerge.

Safety Information

Chlorsulfuron 75 WG is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. 

Keep people and pets away from the area until the product has completely dried.

Special Considerations

Chlorsulfuron 75 WG may affect some plant types. Check the label to ensure your plant can be treated and get confirmation before purchasing.
