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.
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.

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.
