Rometsol Herbicide

Rometsol Herbicide, manufactured by Sipcam Agro USA, is a highly selective dispersable granule herbicide that controls over 75 weed species in native grass areas, rangelands, and pastures. 

This easy-to-use product contains Metsulfuron-methyl 60.0%, which proves efficient in removing broadleaf weeds like sedge and other grass weeds like ryegrass in a wide range of sites. 

Rometsol Herbicide is a flexible post-emergent product that, within a few weeks of application, results in low dosages of annual and perennial grasses and broadleaf weeds. 

Tools Needed

Mix the product into a high-volume sprayer, such as a professional pesticide spraying rig, backpack sprayer, or knapsack sprayer. 

How to Use

• Step 1: Determine how much Rometsol Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). Depending on the weed, use 1/4 (0.25) to 1 fl. oz. of Rometsol Herbicide in 100 gallons of water per acre of ornamental turf. For native grass sites with soils consisting of a pH that is 7.5 or less, apply 1/2 to 2 oz. of product in 100 gallons of water per acre. For rangelands and pastures, use 1/10 to 1 oz. of product per 100 gallons of water per acre, depending on the weed being treated. For spot applications in pastures and rangelands, use 1 oz. of product per 100 gallons of water plus 1/2 pint of surfactant per 100 gallons of spray solution. Do not apply more than 4 ounces of product per acre per year. Do not use more than 1/10 ounce per acre of product for the establishment of native grasses. Do not exceed 1 2/3 oz. of product per acre per year for rangelands and pastures. Refer to the label for specific application rates and restrictions.
• Step 2: Fill the sprayer tank with half the water and add the measured amount of Rometsol Herbicide. Agitate the tank for at least 5 minutes until the product has fully dispersed before pouring the remaining half of the water into the tank. If needed, add the surfactant to the spray mixture and agitate once last time. 
• Step 3: Spray the target weed with Rometsol Herbicide, using a fan spray setting to ensure even coverage. Check back after 4 weeks and reapply according to the label if necessary. 

Where to Use

Rometsol 60DF is recommended for the control of annual and perennial weeds and unwanted woody plants on private, public, and military lands, on rights-of-way, industrial sites, non-crop areas, ditch banks of dry drainage ditches, certain types of unimproved turf grass, and conifer and hardwood plantations, including grazed areas on these sites.

Ornamental turf, such as lawns, parks, cemeteries, and golf courses (fairways, aprons, tees, and roughs) may be treated with this product. This product may also be used on sod farms.

Do not use on Bahiagrass where it is the desired turf, as severe injury may result.

When to Use

Applications of this product can be made at any time of the year as long as weeds are at least 2 to 3 inches in size and the soil is not frozen. Cool-seasoned turf can only be treated when it is not under stress and temperatures are below 85 degrees Fahrenheit. 

Do not apply to turf less than 1 year old.

Do not plant ornamentals such as shrubs and trees in treated areas for at least 1 year after the last application or bedding plants for at least 2 years.

Safety Information

Rometsol Herbicide 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 out of treated areas until sprays have dried.
