June 1, 2021 – BASF has introduced Avelyo™ fungicide for the greenhouse and nursery market. Avelyo fungicide is powered by the active ingredient mefentrifluconazole, providing commercial growers with broad-spectrum protection from difficult diseases with exceptional plant safety.
Avelyo™ fungicide provides control of key diseases including powdery mildews, leaf spots, scab and soilborne diseases caused by Cylindrocladium spp. and Berkeleyomyces spp. (formerly Thielaviopsis spp.). This next-generation demethylation inhibitor (DMI) makes an exceptional rotation partner at any stage of the crop production cycle with no known injury on small plants or plants in flower, unlike other traditional DMI products currently on the market.
“As we continue to expand our solutions, we look for ways to add value for our growers,” said Liz Dunbar, Product Manager – Greenhouse & Nursery, BASF Corporation. “The plant safety of Avelyo fungicide gives growers another rotation partner to use from propagation to market-ready plants.”
Avelyo fungicide also offers long-lasting residual activity and outstanding rain fastness within just one hour, making it a great option for outdoor nursery production where frequent rainfall is common.
Avelyo™ fungicide Product Information:
Avelyo™ fungicide is a broad-spectrum fungicide containing the active ingredient mefentrifluconazole for use in ornamentals. For optimum disease control, apply Avelyo™ fungicide in a regularly scheduled preventive spray program and rotate with non-Group 3 fungicides.
Mode of Action:
Mefentrifluconazole, the active ingredient in Avelyo™ fungicide, inhibits the demethylation step of sterol biosynthesis (DMI), which disrupts cell membrane synthesis and is classified by the Fungicide Resistance Action Committee (FRAC) as a Group 3 fungicide.

Use: Ornamental Use Sites
Commercial and retail nurseries, field and container
- Forest tree, conifer and Christmas tree nurseries and plantations
- Greenhouses, shadehouses, and lathhouses
- Cut flowers, field and greenhouse grown
- Avelyo™ fungicide may be applied to juvenile fruit and nut trees, vine, brambles and bushberries grown in commercial ornamental production nurseries. Immature and/ or inedible fruits or nuts or berries may appear on the plant but are not intended for harvest or consumption.
Begin Avelyo™ fungicide applications preventively (before onset or in the early stages of disease) and continue throughout the season following specified intervals and resistance management guidelines.
- For optimal disease control, apply Avelyo™ fungicide in a preventive disease management program. • Use the shorter specified interval and/or higher specified rate when conditions favor disease or when disease pressure is high.
- Thorough and uniform coverage is required for optimal disease control.
- Application equipment must be cleaned thoroughly before and after applying this product, particularly if a product with the potential for injury was used before application of Avelyo™ fungicide. Nutra-Sol® and NeutralizeTM tank cleaners can be used to remove residues before and after Avelyo™ fungicide application. Flush system with clean water.
For resistance management, Avelyo™ fungicide contains a Group 3 fungicide. Any fungal population may contain individuals naturally resistant to Avelyo™ fungicide and other Group 3 fungicides. A gradual or total loss of disease control may occur over time if these fungicides are used repeatedly in the same treatment areas. Appropriate resistance-management strategies should be followed.
To delay fungicide resistance, take one or more of the following steps:
- Rotate the use of Avelyo™ fungicide or other Group 3 fungicides within a growing season sequence with different groups that control the same pathogens.
- Use tank mixtures with fungicides from a different group that are equally effective on the target pest, apply the minimum application rate labeled by the manufacturer.
- Adopt an integrated disease management program for fungicide use that includes scouting, historical information related to pesticide use, and crop rotation, and which considers host plant resistance, impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other chemical control practices.
- Monitor treatment area for lack of biological efficacy that might indicate possible resistance development.
- Contact your local extension specialist or certified crop advisor for any additional pesticide resistancemanagement and/or Integrated Pest Management (IPM) recommendations for specific crops and pathogens.
- For further information or to report suspected resistance consult your local BASF representative, extension specialist, or certified crop advisor.
