APPLICATION INSTRUCTIONS
The most effective program for control of crabgrass, goosegrass, annual bluegrass, and other annual weeds is designed for local conditions. Two applications per year at specified application rates for a particular weed problem may be necessary. For additional information regarding timing and rate application, consult weed specialists of the State Agricultural Extension Service or the State Agricultural Experiment Station.
TURFGRASSES: Apply PRE-SAN GRANULAR 12.5G to well-established golf course turf only. This product can be used on the following established turfgrasses: Bahiagrass, Bentgrass spp., Bermudagrass spp., Perennial bluegrass, Centipedegrass, Fescue spp., Pensacola bahiagrass, Perennial ryegrass, Rough stalk bluegrass (Poa trivialis), St. Augustinegrass, Red top, and Zoysiagrass. PRE-SAN GRANULAR 12.5G has been used safely on many Bentgrass cultivars.

For the control of crabgrass, apply this product at the specified rate anytime from fall (September or October) through early spring for spring and summer control. With a late winter or early spring application, the application must be made prior to the crabgrass emergence.
For the control of annual bluegrass and other annual weeds, apply PRE-SAN GRANULAR 12.5G at the specified rates before the weeds emerge from the soil.
When the germination of crabgrass, annual bluegrass, and other weeds extend ino the late summer and early fall a second application of PRE-SAN GRANULAR 12.5G at the specified rate should be made 4-5 months after the initial application.
