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 labeled for use on residential lawns and is not labeled for bluestem grass. We do apologize but unfortunately we are unable to find a product labeled for this invasive grass. Roundup spot treatments and reseed in the area would be the best recommendation and one that we are able to find as well when researching this. You may also contact your Master Gardener at your Extension Office. This Master Gardener will be able to give you recommendations on what works best in your region that others may have had success with.
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
Sandbur Management 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. In contrast, sandbur control in areas with thin stands of bermudagrass may not be satisfactory.
Refer to page 13 of the product label for more this information on Sandbur.

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 labeled for established Bermuda pastures if used as directed. In regards to sandbur control, the label states the following: "Apply 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. 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 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. For best results in these situations, apply Pastora® Herbicide in a tank mix with 2.5 to 4.1 ounces active ingredient glyphosate per acre (such as 4 to 6 fluid ounces of a 5.5 pound/gallon product or 5 to 8 fluid ounces of a 4 pound/gallon product). 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 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. In contrast, sandbur control in areas with thin stands of bermudagrass may not be satisfactory.
There are no instructions on whether the Pastora can be injected in the stem to go farther to the root, therefore we cannot advice this type of application.Pastora Herbicide works best if 1-2 inches of rain or irrigatin are applied after application. This will help move the product to the root zone.
