GOLF COURSE TURFGRASS - BENTGRASS DEAD SPOT
Emerald fungicide is a systemic anilide fungicide for the control of dollar spot (Sclerotinia homoeocarpa) and bentgrass dead spot (Ophiosphaerella agrostis) in turfgrass grown on golf courses. Optimum disease control is achieved when Emerald is applied in a regularly scheduled preventive spray program and is used in a rotation program with other effective fungicides. Because of its high specific activity, Emerald has good residual activity against target fungi.
For the control of turfgrass diseases not listed on the label, Emerald may be tank mixed with labeled rates of other fungicides. Follow label directions of any tank mix product and apply at the specified rate based on target disease. All applications should be made according to the use directions that follow. Failure to follow directions and precautions on the label may result in turfgrass injury and/or inferior disease control.
Emerald is a systemic fungicide for the control of dollar spot and bentgrass dead spot on golf course turfgrass. Emerald may be applied as a solo foliar spray or in tank mixes with other registered turfgrass fungicides. DO NOT exceed the specified application rate or fail to comply with use restrictions listed in the Resistance Management and Restrictions and Limitations. All applications should be made according to the use directions that follow.
Uses and Tolerances
Emerald can be used only on turf grown on golf courses. Due to variability within turfgrass species, application techniques and possible tank mixes, neither the manufacturer nor the seller has determined if Emerald fungicide has adequate tolerance on all turfgrasses under all conditions. Therefore, apply the specified rate of Emerald on a small test area under conditions expected to be encountered and monitor for any adverse effects before applying Emerald to the targeted area.
For maximum efficacy, Emerald should be applied prior to or in the early stages of disease development. For maximum efficacy, apply Emerald at the rates indicated in Table 1.
Application Rates and Intervals for Emerald fungicide on Golf Course Turfgrass in 2 to 4 gallons of water per 1000 square feet (87 to 174 gallons per acre). Use the shorter specified application interval and/or the higher specified rate when prolonged favorable disease conditions exist.
Applications should be repeated at the specified interval as necessary.
- Emerald is most effective when applied preventively.
- Actual length of disease control will vary depending on environmental conditions, disease pressure, and turfgrass management practices.
- Calibrate sprayer prior to use.
- After application, allow foliage to dry prior to mowing or irrigation.
- Apply Emerald using sufficient water volume and pressure for adequate coverage of the foliage.
- Apply Emerald as instructed in Specific Use Directions with ground spray equipment.
The active ingredient in Emerald is boscalid, an anilide Group 7 (carboxamide) fungicide. Boscalid is effective against strains of pathogens, such as dollar spot, that are resistant to other fungicides, such as the dicarboximides, sterol inhibitors, or benzimidazoles. Fungal isolates resistant to anilide fungicides, such as boscalid, may eventually dominate the fungal population if boscalid is used predominantly and repeatedly in the same area in successive years as the primary method of control for the targeted pathogen species. This may result in reduction of disease control by Emerald or other Group 7 fungicides.
To maintain the performance of Emerald in turfgrass, DO NOT exceed the total number of sequential applications of Emerald. Adhere to the label instructions regarding the consecutive use of Emerald.
To delay the development of fungicide resistance:
- Tank mixtures
Use tank mixtures with fungicides from different target site of action groups that are registered/permitted for the same use and that are effective against the pathogens of concern. Use at least the minimum labeled rates of each fungicide in the tank mix.
- Integrated Pest Management (IPM)
Integrate Emerald into an overall disease and pest management program. Follow cultural practices known to reduce disease development. Use Emerald in advisory (disease forecasting) programs that recommend application timing based on environmental factors favorable for disease development.
Monitor efficacy of all fungicides used in the disease management program against the targeted pathogen and record other factors that may influence fungicide performance and/or disease development. If Emerald appears to be less effective against a pathogen that it previously controlled or suppressed, contact a BASF representative or
local turfgrass expert for further investigation.
DO NOT make more than two (2) sequential applications of Emerald for disease control for dollar spot or bentgrass dead spot in golf course turfgrass. Then alternate to another effective fungicide before reapplying Emerald.
Restrictions and Limitations
- Maximum seasonal use rate: DO NOT apply more than a total of 1.1 ounces of Emerald per 1000 sq ft per year (48 ounces Emerald per acre per year).
- Refer to Specific Use Directions for sequential application intervals for Emerald.
- DO NOT apply this product to turfgrass except for golf course turfgrass.
- DO NOT apply through any type of irrigation equipment.
- This product cannot be used to formulate or reformulate any other pesticide product.
For tankmix applicaion instruction information, see \"Tank Mixing Information\" section on the label.
General Restrictions and Limitations (For use only in South Dakota)
Do not apply if there is no wind, if wind is gusty, or if wind is in excess of 10 mph. Do not allow this product to drift from the target site.
GOLF COURSE TURFGRASS
Specific Use Directions
Use Emerald for the control of dollar spot and bentgrass dead spot on golf course turfgrass. For maximum efficacy, Emerald should be applied prior to or in the early stages of disease development. Apply Emerald at the rate indicated in 2 to 4 gallons of water per 1000 square feet (87 to 174 gallons per acre). Use the shorter specified application interval and/or the higher specified rate when prolonged favorable disease conditions exist. Applications should be repeated at the specified interval as necessary.
Application Intervals: 14 days.
Begin applications prior to or in the early stages of disease development. Use the shorter specified application interval and/or the higher specified rate when prolonged favorable disease conditions exist.
- Do not apply more than two (2) sequential applications of Emerald. Then alternate to another effective fungicide before reapplying Emerald.
