OHP, Inc., has announced the introduction of Seido Fungicide, a new tool for prevention and early curative control of powdery mildew infections.
Providing translaminar plus vapor activity, Seido offers complete protection of both sides of the leaf while the vapor activity enhances spray coverage to all surfaces of the plant as well as neighboring plants.
"With its unique mode of action, plus preventative, early-curative, and vapor activity, Seido will be a valuable component for all IPM and resistance management programs," says Troy Bettner, OHP vice president of sales and marketing.
Seido (active ingredient pyriofenone) stands alone as the only chemistry available in ornamentals in the FRAC Group 50, notes Dr. Carlos Bográn, OHP senior technical manager, meaning there is no known resistance.
"OHP feels Seido will become a vital part of ornamental growers’ powdery mildew control programs in short order," says Dr. Bográn. "With a 4-hour REI, unique mode of action, and rainfastness within 30 minutes, Seido can easily integrate into any powdery mildew control program."
On both greenhouse and nursery crops, OHP has conducted extensive crop safety evaluations with Seido and the results have shown no adverse effects on plant quality even on open blooms.
As a powdery mildew solution, Seido is compatible with other plant protection solutions including conventional and biological products.
Users may tank mix with other OHP fungicides such as Astun, OHP 6672, OHP Chipco 26019, Terraguard, and Triathlon BA, for broader activity. Users should check with their state regulatory departments for Seido registration status before applying.
