Alligare Grassmaster Herbicide

Mode of Action

Alligare Grassmaster Herbicide contains two active ingredients uniquely formulated to be used alone or tank mixed with other listed products as well as liquid fertilizer solutions.Alligare Grassmaster Herbicide  is readily absorbed by plants through shoot and root uptake translocates throughout the plant’s system and accumulates in areas of active growth. Alligare Grassmaster Herbicide interferes with the plant’s growth hormones (auxins) resulting in the death of many broadleaf weeds.

APPLICATION INSTRUCTIONS

Apply Alligare Grassmaster Herbicide at the rates and growth stages listed in Tables 1 and 2 as follows unless instructed differently by the section on “Food/Feed Crop Specific Information” or “Non-Food/Feed Use-Specific Information.” Applications can be made to actively growing weeds as aerial, broadcast, band, or spot spray applications. Alligare Grassmaster Herbicide may be applied using water or sprayable fluid fertilizer as a carrier. Sprayable fluid fertilizer may be used as the carrier in pre-plant or pre-emergence use for all crops listed on this label. Postemergence uses with sprayable fluid fertilizer may be made on pasture, hayland, or wheat crops only.

The most effective application rate and timing vary based on the target weed species. In mixed populations of weeds, the correct rate is determined by the weed species requiring the highest rate. Delaying application permits weeds to exceed the maximum size and will prevent adequate control.

Aerial Application Methods and Equipment

Water Volume: Use 3 to 10 gallons of water per acre. Use the higher spray volume when treating dense or tall vegetation.

Ground Application (Banding)

When applying Alligare Grassmaster Herbicide by banding, determine the amount of herbicide and water volume needed.

Ground Application (Broadcast)

Water volume: Use 5-40 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation.

Application Equipment: Select nozzle design to produce minimal amounts of fine spray particles. Spray nozzles as close to the weeds as is practical for good weed coverage.

Do not apply with a nozzle height greater than 4 feet above the crop canopy.

Spot or Small Area Application

Alligare Grassmaster Herbicide may be applied to individual clumps or small areas of undesirable vegetation using a handgun or similar types of application equipment. Apply diluted sprays to allow complete wetting (up to runoff) of foliage and stems.
