- SUSPENSION CONCENTRATE
MIRAVIS PRIME Adepidyn Technology Fungicide is a broad-spectrum, suspension concentrate (SC) co-formulated fungicide containing 250 g/L fludioxonil and 150 g/L pydiflumetofen. Designed for key horticultural cropping systems, it delivers preventative and curative protection against targeted fungal pathogens such as Botrytis (grey mould).
In commercial production—such as grape blocks in Sunraysia, the Yarra Valley, or the Hunter Valley, and cherry orchards in Tasmania or the Adelaide Hills—this combination provides dual-site activity to protect developing fruit clusters and plant tissues during critical windows of disease pressure.

Withholding period
WITHHOLDING PERIODS HARVEST Berries including blueberries, raspberries, and strawberries: DO NOT HARVEST FOR 1 DAY AFTER APPLICATION Cherries DO NOT HARVEST FOR 3 DAYS AFTER APPLICATION Lettuce and Leafy vegetables: DO NOT HARVEST FOR 3 DAYS AFTER APPLICATION Grapes including Wine Grapes, Table Grapes and Dried Fruit, and Potatoes: DO NOT HARVEST FOR 14 DAYS AFTER APPLICATION GRAZING Leafy vegetables: DO NOT FEED LEAFY VEGETABLE FORAGE OR FODDER TO LACTATING DAIRY ANIMALS PRODUCING MILK FOR HUMAN CONSUMPTION Berries, Cherries, Grapes, Potatoes: DO NOT GRAZE OR CUT TREATED CROPS, TREATED CROP STUBBLE OR ORCHARDS/VINEYARDS FOR STOCK FOOD
The registered withholding periods require specific harvest delay intervals: 1 day for berries (including blueberries, raspberries, and strawberries); 3 days for cherries, lettuce, and leafy vegetables; and 14 days for grapes (including wine, table, and dried fruit) and potatoes.
For livestock safety, do not graze or cut treated crops, stubble, or orchard/vineyard floors of berries, cherries, grapes, or potatoes for stock food. Do not feed leafy vegetable forage or fodder to lactating dairy animals producing milk for human consumption.
Mode of action
MIRAVIS PRIME combines two distinct biochemical modes of action. Pydiflumetofen is a Succinate Dehydrogenase Inhibitor (SDHI, FRAC Group 7) that disrupts fungal respiration by blocking Complex II in the mitochondrial electron transport chain. Fludioxonil is a phenylpyrrole (FRAC Group 12) that interferes with osmotic signal transduction (MAP kinase). Together, these actives target spore germination, germ tube elongation, and mycelial growth within host tissues.
Resistance management
To prevent or delay the development of resistance in target fungal populations, rotate or alternate MIRAVIS PRIME with fungicides from different FRAC resistance groups (such as Group 3, Group 9, Group 11, or multisite Group M fungicides). Avoid consecutive applications of Group 7 or Group 12 co-formulations within the same spray season, and strictly observe season maximum application limits detailed on the approved APVMA label.
Tank-mix compatibility
Suspension concentrate formulations generally display good physical compatibility with standard crop protection products. However, exercise caution when tank-mixing with emulsifiable concentrates (EC), foliar nutrients, or crop oils, particularly during period of high temperatures or slow drying conditions. Always conduct a small-scale jar test prior to broad-scale mixing, and check the approved label for specific product compatibility cautions.
Handling and environment
When opening the container, preparing spray mixtures, and operating application equipment, wear the personal protective equipment (PPE) specified on the product label. Avoid spray drift onto non-target vegetation, waterways, and non-target organisms. Refer to the approved APVMA product label for mandatory re-entry periods, drift management requirements, and environmental protection guidelines.
Common questions
- Why does this product combine two different active constituents?
- Co-formulating pydiflumetofen (Group 7) and fludioxonil (Group 12) provides two distinct biochemical mechanisms against Botrytis. This dual-site activity improves overall control reliability and reduces the risk of selecting for resistant fungal populations in high-risk vineyard and orchard blocks.
- When is Botrytis management typically prioritised in grapevine management?
- Botrytis risk is highest around flowering (cap fall), pre-bunch closure, veraison, and pre-harvest. Application decisions should rely on weather forecasting, canopy microclimate management, local disease risk monitoring, and spray diary planning.
- How can canopy architecture impact the effectiveness of this fungicide?
- Effective canopy management—such as leaf plucking and shoot positioning—ensures that spray droplets reach internal fruit bunches and target sites. Dense, unmanaged canopies prevent complete coverage, reducing fungicide performance regardless of active selection.
- What should be verified prior to mixing MIRAVIS PRIME with other crop protection products?
- Always read the physical and biological compatibility statements on the approved product label. Perform a physical jar test with local water sources and tank partners to verify stability before filling spray vats.
- How should growers interpret withholding periods listed for crops not on their primary spray plan?
- Withholding periods set legal minimum intervals between application and harvest or grazing across all label-approved crop uses. Always consult the registered use table on the official label to confirm permitted crops, target pests, and mandatory application limits.
