Tombstone Duo Fungicide – Use Rates & Label Recommendations
| PATHOGEN | APPLICATION RATE | WATER RATE | KEY COMMENTS |
|---|---|---|---|
| Brown Patch (Rhizoctonia solani) | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | Apply sufficient irrigation quickly following irrigation to wash Tombstone Duo into the crown and upper root zone (3-6mm of irrigation). |
| Dollar Spot (Sclerotinia homoecarpa) | 3L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | For preventative control apply on a 21-28 day interval when conditions are favourable for disease development. To control existing infections apply on a 14-21 day interval. |
| Winter Fusarium or Fusarium Patch (Microdochium nivale) | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | |
| Anthracnose (Colletotrichum graminicola) | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | |
| Secondary Diseases Leptosphaerulina spp., Curvularia spp. | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | |
| Black and White Helminthosporium (Bipolaris spp., Drechslera spp., Exserohilum spp.) | 2L/ha (20mL/100m²) 280mL per bowling green | 800-1600L/ha (8-16L/100m²) | Make monthly preventative applications from December to March. |
| ERI (Ectotrophic Root Infecting Fungi) | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | Make monthly preventative applications in the three months preceding the disease season (usually early Spring). |
| Spring Dead Spot | 2L/ha (20mL/100m²) | 800-1600L/ha (8-16L/100m²) | Apply as a preventive application in January to March after renovation and recovery of active growth. Make a second application one month later. Apply irrigation to wash Tombstone Duo into the root zone. |

Mode of Action
GROUP 3 11 FUNGICIDE
Tebuconazole, one active ingredient in Tombstone Duo, is a systemic fungicide that once absorbed by roots and leaves moves upwards (acropetal) within the plant. Tebuconazole possesses curative, protective and eradicant activity when controlling turfgrass fungi. Tebuconazole is a Group 3 fungicide. It works in controlling turf pathogens by disrupting the fungi’s membrane function. It is classified as a DMI inhibitor as it stops the demethylation step in the biosynthesis of ergosterol, a vital component of cell walls in many fungi.
Trifloxystrobin is the other molecule in Tombstone Duo Fungicide. Trifloxystrobin has the ability to strongly bond onto plant surfaces through penetration of the waxy layers. This forms a secure reservoir of fungicide to provide long-lasting, weather-protected disease control. Trifloxystrobin works by interfering with respiration in plant pathogenic fungi. It is a potent inhibitor of fungal spore germination and mycelial growth.
Maximising Performance
Good turf disease control requires good coverage. Application should be made using sufficient water to ensure thorough coverage: 800-1,600L of water per hectare. For preventative control apply Tombstone Duo on a 21-28 day interval when conditions are favourable for disease development. For curative control apply Tombstone Duo on a 14-21 day interval. For Brown Patch and ERI disease control, apply sufficient irrigation quickly following irrigation to wash Tombstone Duo into the crown and upper root zone (3-6mm of irrigation). For ERI disease control, make monthly preventative applications in the three months preceding the disease season (usually early Spring). From a resistance management perspective, do not apply more than two consecutive sprays of Tombstone Duo unless mixed with a protectant fungicide from group 14, 28, M2, M3, M4 or M5. Tombstone Duo acts very rapidly and where the turf is of a low nutritional status, a slight yellowing may be seen. This will be corrected by nitrogenous fertiliser applications. Where possible, it is recommended that a fertiliser program should precede the fungicide application.
