Pastora Herbicide is registered to use on hay meadows and bermudagrass pastures, and in non-crop areas. Check with your state extension or Department of Agriculture before use, to be certain Pastora is registered in your state. Do not use Pastora in the following counties of Colorado: Alamosa, Costilla, Conejos, Rio Grande, and Saquache. Pastora Herbicide is a granule that is dry-flowable that suppresses or controls grass and broad-leaf weeds. Pastora is mixed in water and applied as a uniform broadcast spray. A spray adjuvant must be used in the spray mix unless otherwise specified on the label. Pastora is noncorrosive, nonflammable, nonvolatile, and no freezing restrictions.
Pastora controls broad-leaf weeds by pre-emergence and post-emergence activity and grass weeds by post-emergence activity. To get the best results from Pastora, apply it to young, active growing weeds. Weeds that are hardened off by the cold weather or by drought stress may be difficult to control. The use rate depends upon the weed spectrum and size of weeds at application.
Do not use on lawns, walks, driveways, tennis courts, golf courses, athletic fields, or other high-maintenance, fine turfgrass areas, or similar areas.

General Information
Pastora Herbicide controls broadleaf weeds by pre-emergence and post-emergence activity and grass weeds by post-emergence activity. For best results, apply Pastora to young, actively growing weeds. Weeds hardened off by cold weather or drought stress may not be controlled. The use rate depends upon the weed spectrum and size of weeds at application. The degree and duration of control may depend on the following factors:
BIOLOGICAL ACTIVITY AND ENVIRONMENTAL CONDITIONS
Pastora Herbicide is absorbed through the foliage and roots of weeds, rapidly inhibiting their growth. Leaves of susceptible plants appear chlorotic 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.
One to two inches of rainfall or sprinkler irrigation (enough to wet the top 2-3 inches of soil profile) may be needed to move Pastora into the weed root zone before the next flush of broadleaf weeds emerge. The amount of moisture required for sufficient activation increases with crop or weed residue and for finer textured soils. Without sufficient rainfall or sprinkler irrigation to move Pastora into the weed root zone, weeds that germinate after treatment will not be controlled.
Application of Pastora provides the best control in vigorously growing pastures that shade competitive weeds. Weed control in areas of thin grass may not be as satisfactory. However, a bermudagrass canopy that is too dense at application can intercept spray and reduce weed control.
In warm, moist conditions, the expression of herbicide symptoms is accelerated in weeds; in cold, dry conditions, expression of herbicide symptoms is delayed. In addition, weeds hardened-off by drought stress are less susceptible to Pastora.
Weed control or suppression may be reduced if rainfall, or sprinkler irrigation occurs within 4 hours after application.
Weed control should be part of an overall pasture management plan which includes good fertility, adequate moisture (rainfall, irrigation), insect and rodent control, and other agronomic practices which maximize bermudagrass growth. Consult your state cooperative extension service, local agricultural dealer, professional consultant or other qualified authority for specific instructions regarding proper management of bermudagrass pastures.
get the mix right
By John on 07/17/2016
It will take some math to figure out this mix if you're not spraying this out of an airplane,... but when you get it right you'll find that this stuff will last you over 6 years on a small lawn, and control weeds better than MSMA used to!!! I love this stuff! It's like a slow acting MSMA, and when mixed with 2,4-d theres literally not a weed it won't kill post or pre emergent! Careful around trees and shrubs as this stuff is lethal to them.

Does the job
By Scott on 09/22/2017
I live in an area plagued by bluestem. In unimproved pastures the grass is ok though some cattleman say that doesn't have a lot of nutrition. In other areas it is a complete pest. I have now sprayed Pastora twice following label directions for bluestem. The bluestem is dying and both Bermuda and buffalo grass are doing fine.

.025 oz per gallon - how would i measure such a tiny amount? And what is the half-life of the product in case i want to put a garden in the area in future years?
Pastora Herbicide can be measured by 1ml into 2 gallons water or 1/4 teaspoon per 2 gallons water. The half life is up to two years in soil.

Pastora Herbicide is labeled to control sandbur aka sandspur when used as directed on the product label for post or pre emergent control. The label states that grazing animals do not have to be moved off the pasture before, during, or after applying.

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

I have a 5 acre flat area beside my home/yard, how far away should I be to be safe to spray Pastora in the flat area? It is flooded with Sandburg and I want to spray Pastora to try and help control the buds. I just don't want to harm or kill any trees or shrubs.
Pastora Herbicide should be kept outside of the drip line of desirable trees and shrubs.
