Mode of action, resistance management and best practices
Know your product modes of action. Whether applying alone or tank mixing, it’s essential to have knowledge of modes of action to help prolong product efficacy for fungicides, insecticides and herbicides. Important: Always read and follow label instructions. Some products may not be registered for sale or use in all states or counties. Please check with your local extension service to ensure registration status. The PS provides a comprehensive breakdown of the product’s properties, including chemical composition, physical state, purity, and storage requirements. Search for Certificates of Analysis (COA) by entering the products Lot Number. Exclude any hyphens or size information. Ex. The Lot Number is a multi-digit number that can be found on the product label or invoice. Ex. This COO confirms the country where the product was manufactured, and also details the materials and components used in it and whether it is derived from natural, synthetic, or other specific sources. Exclude any hyphens or size information. Ex. The Lot Number is a multi-digit number that can be found on the product label or invoice.
In turf use, fluazinam is a preventive contact fungicide. Fluazinam’s role is best understood as part of a preventive program, not a universal cure-all. FRAC guidance recommends using Fluazinam preventively and rotating or mixing it with fungicides from different cross-resistance groups with satisfactory efficacy. This aligns with the principle that a fungicide works best when its use matches its mode of action, disease target, and timing. Fluazinam use should always follow the approved local label.
Fluazinam in turf disease management
Fluazinam’s preventive action makes it effective against diseases such as dollar spot and Botrytis-related diseases when conditions favor infection. In turf, Secure can be used as a core preventive product or as a tank-mix partner with other products to extend protection from inside out. Its unique multi-site action helps reduce resistance development compared to single-site chemistries.
Practical positioning for turf programs. Use fluazinam before disease pressure becomes severe, and integrate it into a broader disease management plan. Consider local registration status and label instructions for timing, rate, and application intervals. For best results, rotate with products from different FRAC groups to maintain efficacy over multiple seasons.
Relation to other crops and general fungicide context
Beyond turf, fluazinam fungicide is mainly used as a protective contact fungicide in crops like potatoes, vegetables, grapes, legumes, brassicas, and selected fruit crops where local registration allows. Its strength lies in preventive protection, supporting Botrytis, Sclerotinia, and late blight management in appropriate crops, and it should be used as part of an integrated disease management program rather than as a sole remedy.
In crop programs, fluazinam is particularly valued where disease pressure is predictable and preventive action yields highest value. It is not suitable as a universal fungicide for all crops or diseases, and growers are advised to follow local label requirements and integrate cultural practices to maximize results.
