Secure Action Fungicide | GreenCast | Syngenta

Product Overview

When you can protect your fairways like your greens, you’ll get rave reviews

Golf’s leading fungicide, Secure®, is now even better. Secure® Action™ fungicide includes a boost of acibenzolar-S-methyl (ASM), to better prevent and quickly recover from biotic and abiotic stress. With an enhanced formulation of a trusted multi-site contact fungicide, it offers improved dollar spot control and brings the ASM defense to fairways and greens, providing inside out turf protection for your entire course.


Exceptional Disease Control for Enhanced Turf Performance




  • ASM boosts turf’s natural defenses against disease
  • Increases dollar spot control interval up to 21 days
  • Adds suppression of bacterial wilt to the label for effective control of more than 10 key diseases





  • Contact and systemic modes of action
  • Attacks pathogens at multiple sites versus a single site, resulting in a very low risk of resistance development
  • Often controls dollar spot strains found to be resistant to other chemistries
  • Excellent rotation partner with Daconil® ActionTM and Posterity® fungicides






  • Improved disease, drought and heat tolerance means more consistent turf quality and quicker recovery from symptoms of stress







  • ASM helps the plant regulate its stomata to control water vapor release and reduce uncontrolled water loss
  • Better water management improves heat tolerance and avoids wilting
  • Stimulates production of natural proteins to protect cells from damaging heat
  • Enhances the production of enzymes used for photosynthesis



Tips for Success


  1. Protect your turf with a multi-site contact fungicide all season
  2. For suppression of bacterial wilt on bentgrass and Poa Annua greens, apply Secure Action in a seasonal program with Daconil Action or Heritage® Action™.
  3. If dollar spot pressure is high, Posterity fungicide is an excellent rotation partner or tank mix for added protection.
  4. Secure Action is also excellent for curative dollar spot control.


Please review the product label for specific application recommendations.

For guidance on integrating Secure Action into your existing dollar spot control strategy, see Syngenta Agronomic programs.


Season-Long Action for Your Whole Course

Season-Long Action for Your Whole Course

With up to 12 applications per year, Secure Action activates a plant’s natural defense against disease before a pathogen is present by triggering the salicylic acid pathway and protein production in advance of infection.

Research shows that ASM works best when used as part of a season-long program. Rotating Secure Action with Daconil Action or Heritage Action fungicides provides drought mitigation, improved disease control and the ability to recover from abiotic stress for the entire course all season-long.

Know your modes of action

It is essential for superintendents to have a working knowledge of modes of action for fungicides, insecticides and herbicides to aid in the tank-mixing process. These codes, represented as Fungicide Resistance Action Committee (FRAC) codes, Insecticide Resistance Action Committee (IRAC) codes and Herbicide Resistance Action Committee (HRAC) codes, are typically listed on product labels.  Read more »
