Medallion WDG Fungicide

DIRECTIONS FOR USE:

 USE RESTRICTIONS AND PRECAUTIONS:

Hawaii: Use is limited to ornamentals grown in interiorscapes, greenhouses, lath and shade houses, containers, or other enclosed structures. Nassau and Suffolk Counties, New York: Use is limited to ornamentals grown in interiorscapes, greenhouses, lath and shade houses, containers, or other enclosed structures. Do not apply Medallion WDG with any type of aircraft.

MIXING PROCEDURES:

Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this product. Vigorous agitation is necessary to maintain uniformity of the spray mixture. Maintain maximum agitation throughout the spraying operation. Do not let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.

To determine the physical compatibility of Medallion WDG with other products, use a jar test as described below.

Jar Compatibility Test: Using a quart jar, add the proportionate amounts of the products to 1  qt of water. Add wettable powders and water-dispersible granular products first, then liquid flowables, and emulsifiable concentrates last. After thoroughly mixing, let stand for at least 5 minutes. If the combination remains mixed or can be remixed readily, it is physically compatible. Once compatibility has been proven, use the same procedure for adding required ingredients to the spray tank.

If using Medallion WDG in a tank mixture, observe all directions for use, crops/sites, use rates, dilution ratios, precautions, and limitations which appear on the tankmix product label. Do not exceed the dosage rates on any label. Follow the most restrictive label precaution. Do not mix this product with any other product whose label prohibits such mixing. Tank mixtures are permitted only in those states where the tank-mix partner is registered.

Note: Use with oils or adjuvants may cause plant damage.

Plant tolerance has been found acceptable for ornamentals listed in the ORNAMENTALS section of this label. However, not all possible tank-mix combinations have been tested under all conditions. When possible, it is recommended to test the combinations on a small portion of target plants to ensure a phytotoxic response will not occur as a result of application.

Medallion WDG Alone: Add 1/3 of the required amount of water to the spray or mixing tank. With the agitator running, add the labeled amount of Medallion WDG into the spray tank all at once. Continue agitation while adding the remainder of the water. Begin application of the spray solution after the material has completely dispersed into the mix water. Maintain agitation until all of the mixture has been applied.

 APPLICATION INSTRUCTIONS:

Apply Medallion WDG at rates and timings as described in this label.

OBSERVE THE FOLLOWING PRECAUTIONS WHEN SPRAYING IN THE VICINITY OF AQUATIC AREAS SUCH AS LAKES, RESERVOIRS, RIVERS, PERMANENT STREAMS, MARSHES OR NATURAL PONDS, ESTUARIES, AND COMMERCIAL FISH FARM PONDS.

• Do not apply within 75 ft of bodies of water such as lakes, reservoirs, rivers, permanent streams, natural ponds, marshes or estuaries.
• For all plantings within 150 ft of bodies of water as described above, spray crops from outside the planting away from the bodies of water.
• Shut off the sprayer when at row ends.
• Spray the last three rows windward of aquatic areas using nozzles on one side only, with spray directed away from aquatic areas.
• Do not cultivate within 10 ft of aquatic areas as to allow a vegetative filter strip.
• Do not apply when weather conditions favor drift to aquatic areas. Do not apply when gusts or sustained winds exceed 10 mph.
• Do not apply during a temperature inversion. Mist or fog may indicate the presence of an inversion in humid areas.

ORNAMENTALS:

Medallion WDG is a protectant fungicide for control of certain foliar, stem, crown and root diseases in ornamentals grown in interiorscapes, field nursery plantings, container nurseries, forest nurseries, residential and commercial landscapes, greenhouses, lath and shade houses, or other enclosed structures. Medallion WDG may be applied to ornamental crops by foliar spray, drench and mixing with growing media prior to seeding or transplanting. Medallion WDG may be applied by chemigation to control foliar, stem, crown and soil borne diseases.

Medallion WDG controls foliar diseases of ornamentals caused by Rhizoctonia spp., Botrytis spp., Cercospora spp., Cylindrocladium spp., Alternaria spp., Septoria spp., and Myrothecium spp. when applied on a regular schedule as a full coverage spray.

Medallion WDG also will provide control of stem and root diseases caused by Rhizoctonia spp., Fusarium spp. (e.g., F. oxysporum), Cylindrocladium spp., Sclerotium spp., and Thielaviopsis spp., when mixed with the potting media or as a drench to the root zone of plants.

For control of stem and root diseases caused by Pythium spp. and Phytophthora spp., tank mix Medallion WDG with labeled rates of Subdue MAXX. See mixing instructions for these tank mixes.

Maximum Use Rates:

For indoor drench applications, use up to 30 oz of Medallion WDG per 1000 sq ft (80 lb product/A) per year or crop cycle. Applications to pre-potting mix can be made up to 4 oz of Medallion WDG per cu yd.

The high use rates specified for container nurseries, greenhouses, or other enclosed structures are due to the high organic matter soil mixes used in these systems and the high binding affinity of Medallion WDG for organic matter.

For field grown and landscape ornamentals, apply up to a maximum of 1.5 oz/1000  sq ft/year (4 lb product/A/year) and the single maximum application rate is 0.68 lb fludioxonil/A/ application.

For outdoor container grown ornamentals, apply up to a maximum of 3 oz/1000 sq ft/year (8 lb product/A/year).

Foliar Spray

For control of Rhizoctonia spp., Alternaria spp., Septoria spp., Myrothecium spp., and Cercospora spp., use 1-2 oz/100 gallons of water and spray to runoff at 7- to 14-day intervals while conditions are favorable for disease development.

For control of Botrytis spp., use 2-4 oz/100 gallons of water and spray to runoff at 7- to 14-day intervals while conditions are favorable for disease development. For management of the potential development of resistance in the Botrytis population, use no more than two consecutive applications of Medallion WDG before rotating to another effective product registered for Botrytis control on ornamentals with a different mode of action.

For control of Cylindrocladium spp., use 4 oz/100 gallons of water and spray to runoff at 7- to 14-day intervals while conditions are favorable for disease development.

Notes: (1) Under severe conditions, use the highest rate and/or the shortest application interval. (2) Use sufficient spray volume to wet the plants to the point of drip. (3) For a single foliar application, apply up to a maximum of 4 oz/100 gallons (1 oz/25 gal). Not to exceed the maximum single application rate of 0.68 lb fludioxonil/A/application.

Pre-Potting Growing Media Mix

Medallion WDG can be mixed with the potting media before seeding or transplanting by uniformly mixing 1-2 oz per cu yd of potting media. The desired amount of Medallion WDG should be mixed with 0.50-1 gallon of water and applied to 1 (one) cu yd of potting media. It is recommended that Medallion WDG treatment should be made just before the plants are seeded or potted up. Uniform mixing can be accomplished by placing the potting mix in a rotating drum and spraying the Medallion WDG solution onto the mix while the drum is rotating.

Growing Medium Drench

At Seeding

For the control of damping-off, root, and stem diseases, mix 1 oz per 100 gallons of water. When using Medallion WDG for control of Rhizoctonia spp., apply sufficient mix to wet the upper one-half of the growing medium. For control of other root and stem diseases, completely drench the growing medium. Make only one application to the seeding crop prior to transplanting or transfer to larger containers.

Transplants and Cuttings

For the control of root and stem diseases, mix 1-2 oz per 100 gallons of water. When using Medallion WDG for control of Rhizoctonia spp., apply sufficient mix to wet the upper one-half of the growing medium. For control of other root and stem diseases, completely drench the growing medium. If needed, retreat transplants and cuttings with Medallion WDG as described above at 21- to 28-day intervals. Two applications per year during conditions favorable for disease development are usually adequate to control diseases of ornamentals.

Notes: (1) Under severe conditions, use the highest rates and/ or the shortest application interval. (2) For control of Pythium and Phytophthora diseases in addition to Rhizoctonia spp., Cylindrocladium spp., Thielaviopsis spp., Fusarium spp., and Sclerotium spp., tank mix Medallion WDG with labeled rates of Subdue MAXX. (3) Drench applications can be made at up to a maximum of 2 pt/sq ft to wet the root zone of plants.

For Commercial Use in Ornamental Bulb and Corm Dips: Use Medallion WDG for control of basal rot (Fusarium spp.) on ornamental bulbs and corms.

Dip clean bulbs or corms into tanks containing 8 oz Medallion WDG per 100 gallons of water. Place bulbs in a dipping tray or nylon bag for dipping. Tanks should be agitated to suspend Medallion WDG in water and ensure uniform coverage. Soak bulbs or corms at least 20 minutes and air dry prior to storage. Replace liquid in tanks at rate of 0.8 oz Medallion WDG per 10 gallons of water.

Post harvest dipping of bulbs from freshly dug plant material: Clean and treat bulbs within 24-48 hours of digging. Follow instructions above for preparing dip mixture, dipping and drying of bulbs.

Preplant dipping of bulbs prior to planting into fields or bulbs used in containers: Start with clean, dry bulbs. Follow instructions above for preparing dip mixture, dipping and drying of bulbs.
