Features

• A use rate that delivers powerful control of a broad spectrum of soil borne and foliar diseases
• A solo active ingredient formulation of tebuconazole (Fungicide Resistance Action Committee Group 3), making it different from many other products that combine FRAC Groups 3 and 11
• The first DMI fungicide registered by Envu with Stressgard® Formulation Technology
• Tebuconazole is proven to have low growth regulatory impact on both warm and cool season turf

Benefits

• Confidence to start the season with strong disease knockdown and protection, and fast, thorough curative control from upward systemic movement of the active ingredient
• Brings simplification and flexibility to the building of effective fungicide programs that manage resistance, particularly to FRAC Group 11 fungicides
• Increases the flexibility to build season long Stressgard fungicide programs that improve turf health and quality by mitigating abiotic and biotic stress
• Provides confidence of summer safety, and flexibility to use when turf is under growth regulation

A New Tool for Fairy Ring Management

For effective preventative management of Fairy Ring, Dedicate FORTE Stressgard should be applied when soil temperatures increase to an average of 13-16°C at a 5 cm depth, followed by one or more sequential applications after 28 days.

Use of Dedicate FORTE Stressgard in this early-season window will not only control Fairy Ring but will also reduce inoculum and future infections of a wide range of other diseases that typically don’t appear until summer but become active in the early spring.

Examples of such diseases include:

Dollar Spot Anthracnose Brown Patch Fusarium or Microdochium Patch Helminthosporium disease Gray leaf spot Rust Take-All Patch

The Value of Dmi Fungicides

• Some turf managers have moved away from the DMIs for various reasons, such as growth regulation concerns, or due to the introduction of new mode of action fungicides, but the DMI class of chemistry in Dedicate FORTE Stressgard offers some important benefits to turf managers:

Broad spectrum disease control, covering both above ground and below ground diseases important across warm and cool-season turf An important rotation tool for resistance management Dedicate FORTE Stressgard can be used on cool-season greens throughout the year with no significant growth regulation or phytotoxicity (Fig. 1)

Research Results:

Early-season Root Optimization

A study on a couch green in North Queensland showed the benefits on root growth of applying a program of 2 Dedicate FORTE Stressgard applications in early spring, prior to the main summer stress in that geography.

The addition of a Pythium knockdown product, Banol®, and a tool to manage plant pathogenic nematodes, Indemnify®, provided additional early season root growths benefit on a site with historic disease and nematode issues. Figure 2 shows core samples taken from the trial 8 weeks after the 2nd of two monthly applications.

Treatments include Untreated, PrimoMaxx only, Dedicate Forte SG only, Dedicate Forte SG + PrimoMaxx, Tebuconazole only, Tebuconazole + PrimoMaxx. Dedicate Forte SG only and Dedicate Forte SG + PrimoMaxx show the highest turf quality.]

Dedicate FORTE Stressgard improves turf quality compared to the untreated and a generic tebuconazole on creeping bentgrass/wintergrass plots as measured by the area under the turf quality progress curve (AUTQPC). Applications were made every 14 days, from early summer in the Northern Hemisphere, 24 May to 18 July and included Primo®Maxx at 0.4L/hectare, Dedicate FORTE Stressgard at 3.2L/hectare, and generic tebuconazole at the equivalent a.i. rate as Dedicate FORTE Stressgard. Letters are LSD (0.05) for comparing between treatments. University of Connecticut, 2018

Best Practice Application Guidelines

• Dedicate FORTE Stressgard is a broad-spectrum fungicide which is absorbed rapidly and works systemically from within the plant. Good coverage and wetting of the foliage is necessary. Application should be made using sufficient water to ensure thorough, uniform coverage.
• Apply in 400-800 L water per ha for foliar or crown diseases such as Dollar Spot, Anthracnose, Brown Patch, Fusarium (Microdochium), Helminthosporium, Gray leaf spot and Rust. An application is rainfast after drying (approximately 30 minutes) and rain or sprinkler irrigation after this time should not decrease effectiveness.
• Use higher water rates (up to 1600 L per ha) for treatment of soil/root diseases such as Brown Patch, Take-All Patch and Fairy Ring. When targeting applications for soilborne diseases, water in immediately to the depth of fungal activity in the root zone.
• As Dedicate FORTE Stressgard is an acropetal systemic fungicide (moves up in the plant) you will also see protection of above ground plant parts from fungal organisms once the active has moved up from the plant roots to the leaves and stems.
• This product must be used as part of an integrated pest management plan that promotes plant growth and minimizes stress conditions. Apply in all cases when turf is fully established and actively growing. Applications must be applied at prescribed intervals to maintain disease control. Apply growth regulators a minimum of 7 days before or after the application of Dedicate FORTE Stressgard.
• To reduce Pythium inoculum levels and early season infection, tank mix Dedicate FORTE Stressgard with a Pythium active fungicide like Banol®.
• If the site has a known history of plant parasitic nematodes, then Dedicate FORTE Stressgard can be tank mixed with Indemnify® for protection of the roots in spring from nematode attack.
• This product may cause staining. Avoid off-target hardscapes such as cart paths, driveways, pavers, or similar materials. Rinse spray equipment thoroughly with warm water and detergent.
