Postiva™ fungicide from Syngenta now registered for use in California, USA

Date:09-20-2024

Postiva™ fungicide has now been registered for use in California, giving ornamental growers in the state a strong tool to help manage difficult diseases such as Fusarium, leaf spots, Botrytis, powdery mildew and more. 

Postiva is the first fungicide available to ornamental growers powered by ADEPIDYN^® technology, a next-generation SDHI with better, longer-lasting disease control. Through a combination of ADEPIDYN technology and difenoconazole, a DMI (demethylation inhibitor) fungicide, in FRAC Groups 7 and 3, Postiva offers a strong defense against multiple pathogens while helping delay the development of resistance.  

Postiva has also demonstrated strong activity against bacterial pathogens such as Pseudomonas spp. and Xanthomonas spp., broadening the spectrum of control for a complete plant protection treatment.  

″Following the 2022 successful launch across the country, we’re excited to now offer the power of Postiva to ornamental growers in California,″ said Carson Cashwell, market manager for ornamentals for Syngenta Professional Solutions. ″Because of its flexible application methods and its ability to be used in ornamental nurseries, greenhouses, and residential and commercial landscapes, Postiva is an ideal fit for any operation.″  

Postiva can be applied by spray, drench, chemigation or cold fogging to ornamentals, vegetable plants and non-bearing fruit and nut plants grown for retail sales.  

″Solutions like Postiva are an added benefit that expands on our broad portfolio in California,″ said Ron Townsend, technical services manager for Syngenta. ″Growers have testified that Postiva is a product they trust and they rotate it with other fungicides like Mural^®, Palladium^® and Daconil^® brands to create a robust disease and resistance management program.″ 

Ornamental growers can purchase Postiva and Mural together in a convenient Multipak for added savings versus buying the products individually. Beginning Oct. 1 through Dec. 10, growers can take advantage of the best savings of the year with the GreenTrust^® 365 Early Order Period.
