Fungicide combination products: decision-making tools

Updated May 19, 2011

Are they a gimmick by manufacturers, or a great new tool for turf managers? A prescription for fungicide overuse, or a more effective approach that takes advantage of fungicide synergies? These are just some of the questions raised as superintendents try to decide whether a fungicide combination product is the best choice for them.

To help you decide if any given combination product is a good choice for your situation, we have developed two useful tools:

• This PACE Turf Reference on Fungicide Combination Products (140 KB pdf) lists the active ingredients, and their concentrations, in commonly available fungicide combination products.
• This Product active ingredient calculation spreadsheet automatically calculates the rate of each fungicide active ingredient delivered to turf for any product that you are interested in. Calculations are available in both metric and English units.
