New benchmark for onion white rot control

Launched in 2024, Luna® Experience fungicide continues to set the standard for managing onion white rot, maintaining the high level of control established by its predecessor, Luna Devotion.

Onion white rot, Sclerotium cepivorum, is a soilborne fungal disease that severely affects onion crops, leading to significant yield losses. The pathogen infects plants through sclerotia, dormant fungal structures that can persist in the soil for years. 

Phil Bertram, Upper North Island Regional Business Manager for Bayer Crop Science explains, “Onion white rot is particularly challenging to manage, due to its long-lasting persistence in the soil and its ability to devastate entire crops. Cultural control measures such as crop rotation can help, but fungicides such as Luna Experience are essential for a healthy, high-yielding crop.”

Powered by the complementary biological mode of action of its two active ingredients, fluopyram and tebuconazole, Luna Experience effectively disrupts the lifecycle of S. cepivorum. 

Marc Fox, Horticulture and Biologics Product Manager at Bayer Crop Science, explains, "Both fluopyram and tebuconazole have systemic properties and different modes of action. They target multiple stages of the fungal lifecycle preventing the fungus from spreading inside the plant. This delivers robust control and contributes to resistance management." 

For best results, Luna Experience should be applied at 100–150 OWRDD to protect plants before they are vulnerable to infection, with a second application one month later.
