Pastora Range & Pasture Product (2024)

Pastora^® is a selective, broad-spectrum herbicide that provides postemergence control of grassy weeds and postemergence and residual control of broadleaf weeds in bermudagrass pastures, meadows and rights of way.

Pastora herbicide contains two active ingredients: nicosulfuron and metsulfuron methyl (Group 2 herbicides).

Pastora herbicide is registered for use on bermudagrass pastures and hay meadows, and for use in non-crop areas and rights-of-way. Check with your state extension or Department of Agriculture before use to ensure Pastora is registered in your state.

Pastora herbicide is a dry-flowable granule that is mixed in water and applied as a uniform broadcast spray by ground or aerial equipment, or as a spot treatment. A spray adjuvant must be used in the spray mix unless otherwise specified on the Pastora product label.

Pastora herbicide is absorbed through the foliage and roots of weeds, rapidly inhibiting their growth. Leaves of susceptible plants appear pale, yellow, or yellow-white from 1 to 3 weeks after application, and the growing point subsequently dies. The final effects on annual weeds are evident about 4 to 6 weeks after application. The ultimate effects on perennial weeds occur in the growing season following application.

For preemergence weed control, one to two inches of rainfall or sprinkler irrigation (enough to wet the top 2-3 inches of soil) may be needed to move Pastora herbicide into the weed root zone before the next flush of broadleaf weeds emerge. Without sufficient rainfall or sprinkler irrigation to move Pastora into the weed root zone, weeds that germinate after treatment will not be controlled. The amount of moisture required for sufficient activation increases with crop or weed residue and for finer textured soils.

Apply Pastora herbicide to bermudagrass pastures and hay meadows that have been established for at least one growing season. For best results, time applications to young, actively growing broadleaf or grass weeds during spring green-up when annual grasses are less than 2" tall.

There are no grazing or haying restrictions for non-lactating or lactating livestock including cattle, horses, sheep, goats, and other animals when using Pastora herbicide as directed. Grazing animals do not have to be moved off the pasture before, during, or after applying Pastora.

Spot applications may be made using equipment such as back pack, ATV, or hand sprayers. Thorough coverage of foliage and stems is necessary to optimize results. Use an adjustable conejet nozzle with an orifice size of X6 to X12 or equivalent. The application volume required will vary with the height and density of the weeds or brush and the application equipment used.

Unless otherwise directed, applications of Pastora herbicide must include a surfactant. Nonionic Surfactant (NIS) is the preferred surfactant under most conditions. Surfactant products must contain at least 60% NIS with a hydrophilic/lipophilicbalance (HLB) greater than 12. In addition, ammonium nitrogen fertilizer and/or antifoaming agents can be used unless specifically prohibited by tank-mix partner labeling. Consult your local Envu CropScience LP fact sheets, technical bulletins, and service policies prior to using other adjuvant systems.

No, Pastora herbicide should not be used under or around any desirable trees.
