Amparo Herbicide (Milestone) gallon (128 oz)

Amparo Herbicide

Amparo Herbicide is a professional systemic herbicide containing aminopyralid for selective control of invasive, noxious, annual, biennial, and perennial broadleaf weeds, selected woody plants, vines, and certain annual grasses. Its Group 4 synthetic auxin chemistry provides postemergence activity throughout susceptible plants while also delivering residual soil activity against susceptible emerging seedlings and regrowth of certain perennial weeds.

A generic equivalent to Milestone Herbicide with the same active ingredient and concentration, Amparo is labeled for Range & Pasture, CRP acres, wildlife habitat, natural areas, rights-of-way, industrial vegetation management, wheat, and field corn. Its low use rates, systemic activity, residual performance, broad application flexibility, and tolerance of many established desirable grasses make it a valuable tool for invasive-species management and broadleaf weed control.

Features & Benefits

✓ Contains 40.6% aminopyralid salt delivering 21.1% aminopyralid acid equivalent and 2 lb ae per gallon

Winter Annual Grasses: Amparo has specific preemergence programs for control or suppression of medusahead rye, downy brome or cheatgrass, and other susceptible winter annual grasses when applications are properly timed before germination.

Wheat & Corn Programs: crop-specific label directions additionally cover or suppress wild buckwheat, chamomile, curly dock, horseweed or marestail, volunteer lentils, prickly lettuce, mayweed or dogfennel, volunteer peas, annual sowthistle, sunflower, biennial wormwood, field bindweed, knotweed, lady's thumb, lambsquarters, mustard species, field pennycress, pigweed species, green smartweed, perennial sowthistle, Canada thistle, and Russian thistle according to crop-specific directions and control or suppression classifications.

Application Notes

For Range & Pasture, natural areas, CRP, and non-crop applications, Amparo may be applied as a ground or aerial broadcast treatment, calibrated spot treatment, high- or low-volume foliar spray, basal bark treatment, stem-bark treatment, cut-stubble treatment, cut-stump treatment, tree injection, hack-and-squirt treatment, or frill and girdle treatment according to the target species and site. Most broadcast weed-control rates range from approximately 3 to 7 fl oz per acre. Do not apply more than a total of 7 fl oz per acre per year from broadcast, spot, or repeat treatments. Spot treatments may use an equivalent broadcast rate up to 14 fl oz per acre provided no more than 50% of an acre is treated at that rate.

For optimum uptake and translocation, treat actively growing weeds and avoid mowing, haying, shredding, burning, or soil disturbance for at least 14 days following application. A high-quality nonionic surfactant containing at least 80% active ingredient is recommended at 0.25% to 0.5% v/v under hot, dry, dusty, low-humidity conditions or when treating mature or heavily pubescent weeds. Amparo may be tank mixed with appropriately labeled herbicides for broader weed and brush control. Follow separate crop-specific rates and timing for wheat and field corn.
