Early Disease Protection and Proven Weed Control for Wheat

Read the entire report from

our technical services team



Features and Benefits

  • Convenient tank-mix timing: Manage early spring diseases with Topguard® fungicide and control broadleaf weeds with Affinity® Broadspec herbicide with TotalSol® soluble granules during green up (Feekes 3-7).
  • Combines the benefits of a highly systemic and long-lasting triazole fungicide with a market-leading, broadleaf herbicide with rotational flexibility.
  • Topguard fungicide is upwardly systemic to provide protection of newly emerging wheat tissue after application, suppressing disease and protecting vegetative growth prior to standard flag leaf timing fungicide application.
  • Follow with Topguard or Topguard EQ fungicide at flag leaf for superior protection and maximum yields. This program approach to managing diseases through the whole growing season is referred to as Topguard “5 on 5.”

Application Guidelines

May be applied via air or ground. Apply in a minimum of 10 gallons of spray solution per acre by ground and a minimum 5 gallons of spray solution by air. For broader weed spectrum, add MCP (amine or ester) at 6-10 fl. oz./A. Use of a non-ionic surfactant @ 1/4-1/2% is recommended to be added to improve weed/disease control.

Research Trials

Research trials have shown that Topguard® fungicide at 5 fl. oz./A applied at green up (Feekes 3-7) and then followed by Topguard fungicide at 5 fl. oz./A applied at flag leaf (Feekes 8-10)1 provides affordable, effective control of important wheat diseases and, ultimately, increases yields. This program approach to managing diseases through the whole growing season is referred to as Topguard “5 on 5.” Diseases such as common and stripe rust, powdery mildew, leaf and glume blotches, and tan spot1 are controlled by this program.
