WHAT IS Emerald® Emerald is a new generation broad spectrum contact fungicide. Emerald is the perfect partner to use in rotation with Dacogreen WeatherShield to deal with troublesome diseases. Colin Campbell (Chemicals) have been developing Emerald for a number of years to bring a new active ingredient (Fluazinam), that is broad spectrum and versatile, to use in an ever changing climate.
HOW DOES Emerald® WORK As mentioned Emerald is a contact fungicide and is a multi site mode of action. This means Emerald disrupts the production of energy at multiple metabolic sites within the fungal cell. Resistance risk is very low due to this. Emerald is (FRAC) Group 29 Fungicide.
The perfect partner with Dacogreen WeatherShield. With variable weather conditions turf managers need to know what they put out will be effective. Dacogreen has proven this time and time again with it’s unique sticking properties. Now we have Emerald. Emerald binds to the plant very quickly. Once spray is dry product is rainfast (usually within 2 hours). Emerald does not wash off the plant unlike other contact fungicides. The Emerald formulation holds fungicide to the surface of leaf blades even after irrigation and heavy rains. In the below rain fastness study, plants treated with 2 fungicides (Emerald and Daconil® Weatherstik) were subjected to an artificially simulated rainfall events (20 mm/hr) at 2 hours and 24 hours following fungicide application.
In the study, the plant leaves were then inoculated with disease spores, incubated then placed in ideal growing conditions for 3 days. Following this period the plant leaves were assessed for disease presence and control achieved by the fungicides. The results below indicate that disease control was achieved with both PPM rates of both products, indicating that Emerald was equivalent to Daconil Weatherstik when it comes to rainfast properties

Other features of: Emerald® • Emerald has shown to have quicker recovery of dollar spot than DMI fungicides. • Emerald can be used in any temperature range as there is no phytotoxicity to any turf grass variety • Emerald is active all year round as it is not temperature sensitive (DMI Group 3 Fungicides need air temperature to be at least 10oC to be active and will not work as efficiently if the plant is under stress. Emerald does not have any of these issues). • Emerald is a water based formulation Emerald has very good tank mixing features. However, it is highly recommended to conduct a jar test and/or a small plot test to make sure as other variables can influence results.
Emerald® (LABEL EXTRACT)
| Situation | Diseases Controlled | Rate/ha | Critical Comments |
|---|---|---|---|
| Turf including but not limited to bowling greens, fairways, golf greens, racetracks, sports fields and tees | Dollar Spot (Sclerotinia homeocarpa) Helminthosporium Disease (Bipolaris spp., Drechslera spp. and Exserohilum spp.) Gray Leaf Spot (Pyricularia grisea) Anthracnose (Colletotrichum graminicola) | 1-1.5L in 400L-800L water | Emerald should be applied as a preventative treatment. Spray when conditions are favourable for disease development and/or as soon as possible after first symptoms are detected. Make a second application 7 to 14 days later if conditions continue to favour disease development. Use rates towards the higher end of the range and shorten intervals. DO NOT mow or water treated area until turf or lawn is thoroughly dry, ideally allow 24 hours. |
Application volume for leaf and crown diseases (Dollar Spot, Helminthosporium Disease, Grey Leaf Spot and Anthracnose) should be adequate to ensure thorough and even coverage of the turf leaves and penetration into the crowns. Ideal application volumes should be between 400 – 800 L/ha. For best results use coarse [Turbo Teejet* or AIXR Teejet* (11004 or 11005)] nozzles, at 5 km/h and 3 bar pressure. In higher cut turf (>15 mm) a significant spray shielding effect can occur, impacting negatively on spray penetration and even coverage at low application volumes. Good control requires good coverage. Application should be made in sufficient water to ensure thorough coverage. Do not apply more than 3 application of Emerald per season.

Trial Work for Emerald®
[Chart: Emerald Efficacy Dollar Spot. Bar chart showing disease control at 0, 14, and 28 DAT for Emerald 1L/ha, Emerald 1.5L/ha, Standard Fungicide (Contact), and Untreated Control.]
NOTE: Look at all treatments on a specified day. For example look at all orange columns together. Do NOT compare the different colour column to each other.
About the trial Turf type: bent grass green. Dollar Spot pressure was extreme during the trial period as indicated from untreated control. The site has history of dollar spot. Two applications were made 14 days apart for all treatments
Conclusions from trials All treatments needed 2 applications to reduce disease to acceptable level Emerald significantly better at the 1.5L/ha rate than the 1L rate. Emerald second application of 1.5L rate performed statistically the same as the standard treatment.
“When nothing else worked Emerald did. It was the only chemical I could control dollar spot with. It’s not just a new active ingredient but a new chemical group.” Shane George Superintendent

[Chart: Emerald Efficacy Anthracnose. Bar chart showing disease control at 0, 14, and 28 DAT for Emerald 1L/ha, Emerald 1.5L/ha, Standard Fungicide (Systemic), and Untreated Control.]
NOTE: Look at all treatments on a specified day. For example look at all orange columns together. Do NOT compare the different colour column to each other.
About the trial Turf type: bent/poa green mix. Disease pressure was high during the trial period as indicated from the untreated control. The site has a history of anthracnose. Two applications were made 14 days apart for all treatments
Conclusions from trials All treatments needed 2 applications to reduce disease to acceptable level Emerald (both rates) performed statistically the same as the standard systemic fungicide treatment.

[Chart: Emerald Fungicide Trial Gray Leaf Spot. Bar chart showing disease control at 0, 14, and 28 DAT for Emerald 1L/ha, Emerald 1.5L/ha, Standard Fungicide A (contact), and Untreated Control.]
NOTE: Look at all treatments on a specified day. For example look at all orange columns together. Do NOT compare the different colour column to each other.
About the trial Turf type: Buffalo grass Gray leaf spot pressure was extreme with close to 100% infection in plots and only dropping slightly for the duration. The turf farm site has a history of gray leaf spot. Two applications were made 14 days apart for all treatments
Conclusions from trials All treatments needed 2 applications to reduce disease to acceptable level due to the high infection rate. Emerald performed statistically same as the standard treatment.

[Chart: Emerald Efficacy Helminthosporium. Bar chart showing disease control at 0, 14, and 28 DAT for Emerald 1L/ha, Emerald 1.5L/ha, Standard Fungicide (Contact), Standard Fungicide (Systemic), and Untreated Control.]
NOTE: Look at all treatments on a specified day. For example look at all orange columns together. Do NOT compare the different colour column to each other.
About the trial Turf type: Green couch fairway. This trial was conducted on a fairway where helminthosporium pressure is typically high during winter. Heavy dews were present throughout the trial period. Helminthosporium pressure was moderate to high during the trial period. Two applications were made 14 days apart for all treatments
Conclusions from trials Starting from a high rate of infection (close to 100%), all treatments needed 2 applications to reduce disease to a minimum level. Emerald performed statistically the same as the standard for both contact and systemic products.
