Pastora Herbicide is not labeled for use in buffalo grass pasture and could injure it. It is only labeled for Established Bermudagrass Pastures and Hay Meadows Bermudagrass Turf.
Pastora Herbicide is safe on Bermudagrass, bluegrass, ryegrass, & tall fescue pastures and hay meadows, it is not for use on home lawns.
Once sprayed with Pastora Herbicide, there are no instructions or restrictions on the product label as to why you couldn't overseed with your ryegrass in the fall.
Pastora is labeled for application on established bermudagrass pastures, hay meadows, and bermudagrass turf only. Pastora Herbicide label states: Do not use on lawns, driveways, walks, tennis courts, golf courses, athletic fields, or other high-maintenance, fine turfgrass or other areas.
Since Pastora does not list Kleingrass on the label, we cannot say if it will work. We suggest contacting your county extension office for advice on what will work.
Pastora Herbicide is labeled for sandbur in bermudagrass pastures. Per the product label, apply at 1 ounce per acre and make applications when sandbur is newly germinated to 1.5" tall. Make applications when bermudagrass is less than 4" tall, following green-up in the spring or after cutting for hay.
Please review page 13 of the product label for more information on Sandbur treatments.
Pastora Herbicide is not specifically labeled for Sida Rhombifolia plants/weeds. Instead, GrazonNext HL Herbicide is labeled to target prickly sida and may be safely applied to pastures as long as you are following the instructions on the product label. This product is not specifically labeled for the arrowleaf sida, so if the product happens not to work for the arrowleaf sida as well, we would suggest spot treating the areas with a non-selective herbicide such as RoundUp, and then reseed the areas to fill in any bare spots.
Pastora Herbicide is Not for Use on Lawns.
Since Pastora Herbicide is a pre and post emergent, it would be best to wait at least 1 year to plant in the area, though the label states it can remain in the soil for up to 34 months.
Pastora Herbicide is only available as a dry-flowable granule.
The amount of the Pastora Herbicide product you will use will depend on how much area you will be treating. The product label states that 1 oz per acre should be used for field sandbur. Please be sure to review the product label for more information and complete application instructions. Page 13 offers specific information about treating sandbur and how to achieve the best results.
Pastora Herbicide is primarily labeled for post emergent control of sandbur and best applied when the sandbur is newly germinated to 1.5” tall per the product label. For overwintering sandbur or newly germinated sandbur that is greater than 1.5” tall, applications of PASTORA® HERBICIDE may only suppress growth resulting in a reduction in sandbur seedheads.
Per page 13 of the Product Label for Sandbur: Make applications when bermudagrass is less than 4” tall following green-up in the spring or after cutting for hay. Tall, dense stands of bermudagrass can intercept spray and reduce sandbur control. In some areas, sandbur may overwinter and start the new season with an established root system.
For overwintering Sandbur that is greater than 1.5”, it is best to tank mix Pastora Herbicide with a glyphosate non selective at the rate of 0.156 to 0.257 pounds glyphosate per acre. A follow-up application of PASTORA® HERBICIDE may be necessary to control subsequent germination (flushes) of sandbur following the first application or when the first application was made to larger sandbur or under unfavorable environmental conditions.
Sandbur Management must 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. In contrast, sandbur control in areas with thin stands of bermudagrass may not be satisfactory.
Since Pastora Herbicide is a pre and post emergent, it would be best to wait at least 1 year to plant in the area, though the label states it can remain in the soil for up to 34 months.
If mowing prior to applying Pastora Herbicide, it would be recommended to wait 10 to 14 days after mowing to do the application.
For sandbur control, the product label states to apply when sandbur is newly germinated to and less than 1.5 inches tall. In spring, make applications when bermudagrass is less than 4” tall following green-up in the spring or after cutting for hay.
For overwintering sandbur or newly germinated sandbur that is greater than 1.5 inches tall, applications of Pastora Herbicide may only suppress growth resulting in a reduction in sandbur seedheads. In this type of application, it would be recommended to use Pastora in a tank mix with a non selective glyphosate herbicide at the rate of 2.5 to 4.1 ounces per acre as in some areas, sandbur may overwinter and start the new season with an established root system

Yes, Pastora Herbicide needs an additional 1 to 2 inches of rainfall or irrigation is needed to move the product into the weed root zone to prevent them from germinating. Without addtional irrifation, weeds that germinate after treatment will not be controlled.
This product is labled for post emergent control for grassy weeds only (with the addition of a Non Ionic Surfactant) and for pre and post emergent control of both grassy and broadleaf weeds.
Application rates for Pastora Herbicide range from 1 - 1.5 oz. per acre using sufficient volumes of water to evenly and thoroughly cover 1 acre. For post emergent weed control as spot treatments, use 2.5 fl oz per 25 gallons of water per acre along with 16 to 64 oz of NIS per 25 gallons of water.
Refer to the product label for more information on specific weeds controlled and site treatment areas.
The rate of 1.5 ounces of Pastora Herbicide can treat an acre. The amount of water really depends on how much water it takes you to cover that area, that can depend on the type of equipment, height, and walking pace or driving speed, this can be different for everyone. We recommend to calibrate your sprayer to determine the amount of water you will need specifically to make an application. Please read the product label for complete application instructions.
Pastora Herbicide is not for use around anything consumable by humans, it is only for use on Established Bermudagrass Pastures and Hay Meadows Bermudagrass Turf. You can spray the area with a non selective like Roundup to kill everything in an area and you can plant in 2 weeks or you can use an over the top grass killer if just grass is your issue.
The rate for Pastora is 1-2.5 oz. per acre, depending on what weed(s) you are treating. You can find use rates for specific weeds on the product label. This is typically mixed with at least 20 to 50 gallons of water.
