Cevya Fungicide - 100 fl Oz

Cevya Fungicide - Mefentrifluconazole Group 3 Broad-Spectrum Fungicide for Specialty Crops

Cevya Fungicide from BASF is a highly concentrated, broad-spectrum fungicide powered by Revysol - mefentrifluconazole at 34.93% (3.34 lb ai/gal) - the first and only isopropanol-azole active ingredient on the market. Mefentrifluconazole is a sterol biosynthesis inhibitor (DMI) classified in FRAC Group 3, and its unique isopropanol-azole chemistry gives it a distinct binding profile within the DMI class that provides stronger, more consistent activity across a wider range of fungal pathogens compared to conventional triazoles. Cevya delivers both preventive and curative disease control with 1-hour rainfastness and systemic activity, and it was the first DMI fungicide to receive the EPA's Reduced Risk classification - a distinction that reflects a favorable environmental and toxicological profile that may support long-term registration stability as older DMI registrations face scrutiny. Cevya is labeled for use across a broad spectrum of specialty crops including pome fruits, stone fruits, grapes, tree nuts, berries, strawberries, citrus, and a wide range of vegetable crops.

Key Benefits

• First and only isopropanol-azole - mefentrifluconazole's unique molecular structure distinguishes it from conventional triazole DMIs, providing a differentiated binding profile within Group 3 that offers stronger activity against key pathogens and improved cross-resistance management compared to older-generation DMI fungicides.
• Preventive and curative activity - Cevya can be applied preventively in a regular spray program or curatively after infection to stop disease progression; its systemic nature allows it to redistribute within the plant after absorption for extended protection.
• Broad disease spectrum - provides effective control of powdery mildews, Alternaria leaf spots and blights, Monilinia (brown rot, blossom blight), anthracnose, apple scab, black rot, Botrytis (suppression), and more across a wide range of host crops.
• 1-hour rainfastness - absorbed and rainfast within 1 hour after application dries, protecting the investment even when weather conditions are unpredictable.
• First DMI with EPA Reduced Risk classification - a highly favorable regulatory profile that reflects low toxicological and environmental risk and may help maintain long-term registration access as older DMI fungicides are withdrawn.
• Broad crop label - registered for use on pome fruits, stone fruits, grapes, tree nuts, berries, strawberries, citrus, cucurbits, fruiting vegetables, leafy vegetables, bulb vegetables, root vegetables, and more; see the full Detailed Use Directions for the complete crop list.
• Flexible application methods - can be applied by ground equipment, aerial application, or through field sprinkler (chemigation) systems, accommodating a range of orchard and field operation setups.
• Strong resistance management profile - the unique chemistry of mefentrifluconazole makes it a valuable rotation partner for resistance management programs, particularly in crops where Group 3 resistance is a concern.

Crops & Target Diseases

Cevya is registered for use across a wide range of specialty crops. Key crop groups and the primary diseases controlled include:

• Pome Fruits (apple, pear, quince, crabapple, and others) - apple scab, powdery mildew, Alternaria leaf spot, Monilinia blossom blight, sooty blotch, flyspeck, and others
• Stone Fruits (peach, nectarine, cherry, plum, apricot, and others) - brown rot (Monilinia spp.), powdery mildew, Alternaria leaf spot, anthracnose, and others
• Grapes - powdery mildew, black rot, Phomopsis, Botrytis bunch rot (suppression), and others. Note: Cevya or Cevya tank mixes may cause cosmetic leaf injury on Vitis labrusca and V. labrusca hybrid varieties; consult a BASF representative before use on these varieties.
• Tree Nuts (almonds, walnuts, pecans, pistachios, hazelnuts, macadamia, and others) - powdery mildew, Alternaria leaf spot, anthracnose, hull rot, and others
• Berries & Strawberries (blueberry, blackberry, raspberry, strawberry, and others) - powdery mildew, anthracnose, Botrytis, Alternaria, and others
• Citrus - melanose, greasy spot, Alternaria brown spot, and others
• Fruiting Vegetables (tomatoes, peppers, cucumbers, squash, melons, eggplant, and others) - powdery mildew, Alternaria, Botrytis, anthracnose, and others
• Root & Bulb Vegetables (potatoes, carrots, beets, onions, garlic, and others) - early blight, black dot suppression, Alternaria, and others
• Leafy Vegetables - powdery mildew, Alternaria, and others

See the Detailed Crop Use Directions on the label for the complete and current list of registered crops, diseases controlled, specific rates, PHIs, and any crop-specific restrictions.

Application Rates & Timing

For optimum disease control, apply Cevya on a regularly scheduled preventive spray program and rotate with non-Group 3 fungicides. Begin applications before disease onset and maintain spray intervals appropriate for local disease pressure and weather conditions:

• Application rate: 3–5 fl oz per acre, with specific rates for each crop and disease as listed in the Detailed Crop Use Directions on the label
• Annual maximum: Do not apply more than 15 fl oz (0.39 lb mefentrifluconazole) per acre per year from all mefentrifluconazole-containing products combined
• Application frequency: Do not make more than 3 applications at 5 fl oz or 5 applications at 3 fl oz per acre per year; minimum re-treatment interval is 21 days
• Sequential application limit: Do not make more than 2 sequential applications of Cevya before alternating to a fungicide with a different mode of action (non-Group 3); this restriction is critical for resistance management
• Ground application: Adjust spray volume for thorough, uniform canopy penetration and coverage of foliage, bloom, and fruit
• Aerial application: Minimum of 10 gallons of spray solution per acre; do not apply in spray solutions less than 50% water by volume
• Chemigation: May be applied through field sprinkler irrigation systems; follow chemigation directions on the label
• Pre-harvest interval (PHI): Varies by crop - refer to the crop-specific use direction table on the label for the applicable PHI for each crop

Do not use in greenhouse production. Do not apply to Vitis labrusca or V. labrusca hybrid grape varieties without first consulting a BASF representative. Runoff of this product to surface water is possible, particularly on poorly draining soils; avoid application when rainfall is forecast within 48 hours. The cumulative seasonal maximum of 0.39 lb ai/acre/year applies to all mefentrifluconazole-containing products in total, not just Cevya alone.

ALWAYS READ AND FOLLOW LABEL DIRECTIONS BEFORE USE.

Why Professionals Choose Cevya

Specialty crop growers face a narrowing toolbox for DMI fungicides as older-generation triazole registrations come under increasing regulatory pressure - and Cevya is built precisely for that moment. Its isopropanol-azole chemistry brings a genuinely differentiated binding profile within Group 3, providing stronger, more consistent performance against powdery mildews, Monilinia, Alternaria, and other key specialty crop pathogens than many conventional DMIs. The 1-hour rainfastness, systemic redistribution, and flexible application platform (ground, aerial, chemigation) make it practical across a wide range of orchard and field operations. And as the first DMI to earn the EPA's Reduced Risk designation, Cevya carries a regulatory profile designed to weather the long-term trends in agricultural fungicide risk assessment - making it a sound choice for growers who want to build their disease management programs on durable, registration-stable chemistry.
