Renown is a broad spectrum fungicide with contact, systemic, preventive and curative properties recommended for the control of many important plant diseases. All applications should be made according to the use directions that follow.
Renown is effective for strategic use in programs that attempt to minimize disease resistance to fungicides. Some other fungicides that are at risk from disease resistance exhibit a single-site mode of fungicidal action. Renown, with a multi-site mode of action, may be used to delay or prevent the development of resistance to single-site fungicides. Consult your Federal or State Cooperative Extension Service representatives for guidance on the proper use of Renown in programs which seek to minimize the occurrence of disease resistance to other fungicides.
Integrated Pest (Disease) Management
Renown is an excellent disease control agent when used according to label directions for control of a broad spectrum of plant diseases. Renown is recommended for use in programs which are compatible with the principles of Integrated Pest Management (IPM), which include the use of disease resistant crop varieties, cultural practices, pest scouting and disease forecasting systems which reduce unnecessary applications of pesticides.
Renown is a mixture containing chlorothalonil (a Group M5 fungicide) and azoxystrobin (a Group 11 fungicide). Accordingly, Renown has two modes of action:
1) Chlorothalonil (a Group M5 phthalonitile fungicide) is a multi-site contact fungicide.
2) Azoxystrobin (Group 11) is an inhibitor of the Qo (quinine outside) site within the electron transport system (QoI) as well as disrupting membrane synthesis by blocking demethylation.
Fungal pathogens can develop resistance to products with the same mode of action when used repeatedly. Renown is not cross-resistant with any other classes of fungicides which have different modes of action. Because resistance development can not be predicted, use of this product should conform to resistance management strategies established for turf in your area. Consult your local or state turf authorities for resistance management strategies that are complementary to those in the label.
Resistance management strategies may include rotating and/or tank-mixing with products having different modes of action or limiting the total number of applications per season. Avoid alternation with other Group 11 fungicides such as pyraclostrobin and trifloxystrobin. Renown should not be alternated or tank-mixed with fungicides to which resistance has already developed. Continual use of Renown may allow less sensitive strains of pathogens to increase in population and reduce the efficacy of Renown. Syngenta encourages responsible resistance management to ensure effective long-term control of the fungal diseases on the label.
Since pathogens differ in their potential to develop resistance to fungicides, the DIRECTIONS FOR APPLICATION section in the label provides resistance management strategies specific for each crop and disease.
Renown may be applied with most types of spray equipment commonly used for making ground applications.
DO NOT apply Renown aerially.
DO NOT apply Renown through any type of ultra low volume (ULV) spray system.
SPRAY DRIFT PRECAUTIONS
DO NOT apply Renown aerially.
Renown is extremely phytotoxic to certain apple varieties.
AVOID SPRAY DRIFT. Extreme care must be used to prevent injury to apple trees (and apple fruit).
DO NOT spray Renown where spray drift may reach apple trees.
DO NOT spray when conditions favor drift beyond area intended for application. Conditions which may contribute to drift include thermal inversion, wind speed and direction, sprayer nozzle/pressure combinations, spray droplet size, etc. Contact your state extension agent for spray drift prevention guidelines in your area.
DO NOT use spray equipment which has been previously used to apply Renown to spray apple trees. Even trace amounts can cause unacceptable phytotoxicity.
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR.
Do not apply when weather conditions favor drift from treated areas to non-target aquatic habitat.
TURF DIRECTIONS FOR APPLICATION
Proper adjustments and calibration of spraying equipment to give good canopy penetration and coverage is essential for good disease control.
The higher rates in the rate range and/or shorter spray intervals may be required under conditions of heavy infection pressure, highly susceptible varieties, or when environmental conditions conducive to disease exist.
Apply Renown in an adequate amount of water to provide complete coverage. This amount may vary from 50 to 90 gallons per acre. Under severe disease conditions use the highest rate and shortest interval corresponding with the application schedule selected from the table in the label.
When used according to label directions, Renown will deliver the appropriate amount of both azoxystrobin and chlorothalonil to provide control of listed diseases.
Turf Restrictions and Precautions:
- ONLY FOR USE ON: turf on golf courses, sod farms, and lawns around commercial and industrial buildings, and professional and collegiate athletic fields.
- DO NOT use on home lawns and turf sites associated with apartment buildings, daycare centers, playgrounds, playfields, recreational park athletic fields, athletic fields located on or next to schools (i.e., elementary, middle and high schools), campgrounds, churches, and theme parks.
- DO NOT apply Renown aerially.
- DO NOT apply Renown through any type of ultra low volume (ULV) spray system.
- Sod Farms: DO NOT apply at rates greater than 13 pounds of chlorothalonil (2.7 gallons of Renown) per acre per year.
- Sod Farms: Renown must not be applied within 25 feet of marine/estuarine water bodies unless there is an untreated buffer area of that width between the area to be treated and the water body.
- Sod farm turf treated with Renown prior to harvest must be mechanically cut, rolled, and harvested.
- DO NOT graze or feed clippings from treated turf areas to animals. Crops (turf) in the label may be planted immediately after last treatment. Do not plant other crops within 45 days after last application.
- DO NOT apply more than two sequential applications of Renown for control of anthracnose and gray leaf spot. For all other diseases, do not apply more than three sequential applications.
- DO NOT use Renown on fine fescue turf due to the potential for phytotoxicity or turfgrass injury.
- DO NOT mow or water after treatment until spray deposited on turfgrass is thoroughly dry; Renown should always be used in conjunction with good turf management practices.
- For rates up to and including 4.5 fl . oz./1,000 sq. ft. (12.25 pt./acre),
- The minimum re-treatment interval is 7 days.
- Maximum single application rate of Renown: 4.5 fl . oz. /1,000 sq. ft (12.25 pt./acre).
- Maximum amount of Renown per growing season refer in the label.
Reapply at 30 day intervals if snow melts.
