Pre Emergent

Pre-emergence weed control with SureGuard® SC is most effective when applied to clean, weed free soil surfaces prior to weed emergence. Moisture is necessary to activate this product on soil for residual weed control. Dry weather following application of this product may reduce effectiveness. However, when adequate moisture is received after dry conditions, this product will control susceptible germinating weeds.

To ensure uniform coverage when using boom sprayers, use 10-40 GAL of spray solution per acre. When making backpack applications, apply 50-100 GAL of spray solution per acre. Nozzle selection should meet manufacturer’s gallonage and pressure recommendation for pre-emergence herbicide application.

Post Emergent

The most effective post-emergence weed control occurs when applied in combination with a surfactant to weeds less than 2” in height. Apply only to actively growing weeds. This product is most effective when applied under sunny conditions at temperatures above 65°F.

SureGuard SC is rainfast 1 HR after application. Applications should not be made if rain is expected within 1 HR of application or efficacy may be reduced.

To ensure thorough coverage when using boom sprayers apply 15-30 GAL of spray solution per acre. Apply 20-30 GAL/ACRE when using a boom sprayer if dense vegetation or heavy residue is present on the soil surface. When applying with a backpack sprayer, apply 1 GAL of spray solution per 500-1,000 SQ FT. Nozzle selection should meet manufacturer’s gallonage and pressure recommendations for post-emergence herbicide application.
