* Injury to pulse crops may occur on coarse-textured soils, low in organic matter (less than 3%) or in fields with variable soils, gravelly areas, sandy areas or eroded knolls. Avoid planting pulse crops in soils containing more than 50% sand. 

Timing: 

Pre-plant or post-seeding (up to 3 days after seeding).  

Fall application - SZ herbicide should be applied to stubble or soil surface to allow moisture from rainfall or snowmelt to move the product into the soil. Apply the product in the fall when the average soil temperature is below 10°C.  

Do not mechanically incorporate after application, in the fall or spring, as this can destroy the herbicide barrier, allowing weeds to escape. Do not apply to frozen soils or existing snow cover to prevent run-off of SZ herbicide. 

Note: SZ herbicide requires minimum of 1/2”, at once, of rainfall for activation. For best control, SZ herbicide must be applied and activated prior to weed emergence. To control emerged weeds, tank-mix with a supported burnoff tank-mix partner. 

Application Information: 

Rates: 57 g/ac or 75 g/ac 

Acres per grower bag:  

  • SZ-75 = 57 g/ac - Minimum: 20 acres; Maximum: 140 acres

Restrictions: 

  • Do not apply SZ herbicide (or any sulfentrazone products) in consecutive years. In case of drought in any of those years, a subsequent application of SZ herbicide should be further delayed.  

  • Do not apply to soils classified as coarse-textured.  

  • Do not apply to soils with organic matter content less than 1.5% organic matter or greater than 6%.
