SAN RAMON, Calif., – Sept. 14, 2020 – Peanut growers now have a new defense against white mold with Excalia™ Fungicide from Valent U.S.A. With mounting pressure from soilborne pathogens, growers need effective tools to manage damaging diseases. The U.S. Environmental Protection Agency (EPA) granted federal registration of Excalia, which offers powerful white mold control, even under heavy pressure, to help growers prevent the yield loss this difficult disease can cause.

According to the most recent Georgia Plant Disease Loss Estimate Report compiled by the University of Georgia Extension, white mold was the most problematic disease for peanut growers, leading to an 8% reduction in crop value on average. This was more than double the loss from the next most serious pathogen, nematodes.

“When peanut growers are dealing with a disease like white mold — especially with high pressure — they can’t risk the yield loss that comes along with not using an effective product,” says Quyntin Brandt, Excalia brand manager for Valent. “Excalia shields peanut crowns through proven Peanut Rx spray programs, giving growers a flexible new option to strengthen their soilborne disease control and protect yield.”

Excalia features a new succinate dehydrogenase inhibitors (FRAC 7) active ingredient, INDIFLIN® (the trademark name for inpyrfluxam), which offers fast-acting, highly systemic movement into the plant tissue. This allows the product to interfere with fungal growth and reproduction for intrinsic potency against damaging peanut pathogens. Excalia also targets Rhizoctonia limb and pod rot and Sclerotinia blight for broad spectrum peanut disease control; plus, it offers suppression of early and late leaf spot.

Excalia is an excellent fit in Integrated Pest Management (IPM) and Peanut Rx programs to protect the crop and improve the production efficiency of a grower’s operation,” adds Brandt. “By bringing exceptional disease control for top peanut diseases, this product will help enhance a grower’s IPM program and the sustainability of their operation.”
