Maximum disease control will be attained when the solution is administered in a regularly scheduled preventive spray program and is utilized in a rotation program with other reliable fungicides. Because of its high specific activity, it will establish good residual action against target fungi.

General Information

Dollar Spot Has Never Seen Anything Like It

And neither have you. Emerald is a different class of fungicide chemistry for dollar spot control. The active ingredient, boscalid, attacks pathogens that cause dollar spot in a unique and highly effective way.

Emerald inhibits a system called complex II in the mitochondria of fungal cells. By depriving the fungal cells of energy, Emerald disrupts fungal growth and development, halting disease development. Both the mode and site of action of Emerald differ from any other fungicides used to control dollar spot, which is why Emerald can effectively control pathogens that have developed resistance to other fungicides. In other words, it works.

Where To Use Emerald

Research shows that Emerald provides excellent dollar spot control in every region of the country, including yours. And Emerald controls dollar spot in most major turf species, including:

  • Creeping Bentgrass
  • Colonial Bentgrass
  • Perennial Ryegrass
  • Annual Ryegrass
  • Kentucky Bluegrass
  • Common Bermudagrass
  • Hybrid Bermudagrass
  • Annual Bluegrass
  • St. Augustinegrass
  • Tall Fescue
  • Bahiagrass
  • Zoysiagrass
  • Centipedegrass

How To Apply Emerald

Because it is a different class of fungicide chemistry for dollar spot control, Emerald can serve as a valuable resistance-management tool. As with all fungicide chemistries, however, Emerald should be applied as part of a rotation. For additional disease control, Emerald can be tank-mixed with other fungicides.

To achieve optimal results, make no more than two successive applications of Emerald. For specific application rates and instructions, consult the product label.
