Tips for DuraCor herbicide

Wet Fertilizer:

  • 16 – 20 oz/acre DuraCor

Dry Fertilizer

  • 16 – 20 oz/acre DuraCor
  • 200 lbs/acre dry fertilizer or carrier
  • Use a colored dye to show coverage
  • Use dedicated PASTURE ONLY equipment
  • Save time & application costs with one trip
  • Fewer weather delays
  • Eliminates risk of drift
  • Cover rougher acres that may not have been sprayed before


Tips for other herbicides: 

  • Apply GrazonNext® HL at a rate of 2 – 2.1 pt/A 
  • Include a dye to alert all users to the presence of the herbicide.
  • Apply at least 200 pounds of fertilizer per acre.
  • Apply when weed species are young, 4-6 inches tall in most cases. Older more mature weeds may be harder to control.
  • The mixing and application equipment must be dedicated for use only on grasslands.
