Albaugh Specialty Products Announces Launch of Prothioconazole 4L Selectâ„¢

ANKENY, IA – (January 25, 2024) Albaugh Specialty Products is pleased to announce EPA registration of Prothioconazole 4L SelectTM (EPA Reg. No. 89442-61). A DMI fungicide, Prothioconazole 4L Select delivers preventive and curative control of many of the most troublesome cool- and warm-season turf diseases.

In addition to control of dollar spot, fairy ring, brown patch, anthracnose, gray leaf spot, snow mold, and other turf diseases, Prothioconazole 4L Select is labeled for use on greens, tees, fairways, and roughs with reduced risk of turfgrass growth regulation commonly associated with other DMI fungicides.

“With Prothioconazole 4L Select, superintendents get a complete fungicide package with low use rates and broad-spectrum disease prevention,” said Russ Mitchell, Director of Albaugh Specialty Products. “Prothioconazole 4L Select is also the first prothioconazole alternative that offers the same 4 lb/gal active ingredient concentration found in Densicor®, delivering low-cost efficacy and high-value disease control on courses.”

Prothioconazole 4L Select is a complementary addition to the full product portfolio and will be available this Spring exclusively through the Albaugh Specialty Products distribution network. For more information on any, and all, products, visit Albaugh Specialty.
