We know combining herbicides with fertilizers provides a one-two punch of benefits. But how does it work? 

 
 

How does UltiGraz℠ Pasture Weed & Feed work?

Impregnated Fertilizer

Impregnation 

Impregnation is the process of applying a concentrated herbicide solution on dry fertilizer granules during the blending process. To get an adequate rate properly distributed, apply DuraCor® or GrazonNext® HL herbicides with at least 200 pounds of dry fertilizer per acre.

Spreaders

Spreader trucks or fertilizer buggies apply the dry product as they would normally apply dry fertilizer alone. From there, rainfall puts the herbicide-fertilizer solution into the soil. DuraCor and GrazonNext HL are soil active herbicides absorbed by weeds through the roots. Weed control is almost entirely dependent on the soil residual activity of the herbicide and root uptake by the weeds.

Expectations

Expectations for weed control should be less when compared to foliar applications. However, research trials have demonstrated up to 85% control while many ranchers have reported better results. 

Benefits of Impregnated Fertilizer

  • Save time and extra application cost—it’s one trip
  • Fewer weather delays
  • Reduced risk of drift
  • No spray equipment needed
  • Self-apply on your schedule if custom application is not available
  • Fits large or small operations

Follow Good Stewardship

DuraCor and GrazonNext HL have no grazing or haying restrictions for any class of livestock, including lactating dairy cows, horses (including lactating mares) and meat animals prior to slaughter. However, label precautions do apply to forage treated with DuraCor and GrazonNext HL and to manure from animals that have consumed treated forage within the last three days. Consult the label for details.
