New Fungicide Timing Solution to Help Corn Growers Take the Guesswork Out of Disease Management

27 February 2026, Iowa: Pioneer announced today the launch of its new Fungicide Timing Solution, an integrated approach designed to help corn growers make more confident, data‑driven fungicide application decisions and protect yield potential.

Each season, growers face significant uncertainty when managing foliar disease. Shifting agronomic conditions and rapidly changing disease pressure make fungicide application timing decisions difficult: A mistimed application can reduce efficacy, yield and return on investment (ROI).

The Fungicide Timing Solution addresses this challenge by bringing together three components: the Granular Insights Fungicide Timing tool with AI-driven data analysis, elite Pioneer^® brand corn genetics, and next-generation Forcivo^™ fungicide – Corteva’s newest corn fungicide with three modes of action. Together, with agronomic guidance from Pioneer, these components form a comprehensive solution designed to simplify fungicide decisions and maximize performance.

Fungicide Timing Tool Leverages Data Science and AI Analysis

Powered by sophisticated data science and agronomic expertise, the Fungicide Timing tool is a digital solution that continuously evaluates field‑specific disease risk throughout the growing season. It integrates localized weather, field conditions, management practices and hybrid disease tolerance to provide growers with clear, actionable guidance on when and where fungicide applications are most likely to deliver efficacy and yield potential.

“The Fungicide Timing tool uses advanced data science and AI analytics to predict disease onset and identify the optimal spray window based on specific field conditions,” said Trenton Brisby, Agronomy Innovation Marketing Manager. “At a time when every application must deliver a positive return, Corteva is offering a precision agriculture solution that helps growers better manage disease risk and maximize ROI potential.”

Elite Pioneer^® Brand Corn Genetics Provide Disease Tolerance

Exclusively from Pioneer, the Fungicide Timing tool helps growers replace calendar‑based sprays and general guidelines with field‑specific timing recommendations to ensure fungicide applications are made when they matter most. The tool takes into account hybrid disease tolerance when analyzing data and generating recommendations.

Pioneer^® brand corn hybrids are bred with robust tolerance to key foliar diseases for consistent performance across environments and proven stress management. Genetic disease tolerance helps slow disease progression, protect yield potential and expand the window for effective fungicide applications.

“For 100 years, Pioneer has been committed to providing its customers with hybrids that provide elite genetics and disease tolerance combined with the agronomic support to maximize yield potential,” said Brandon Walter, U.S. Portfolio Marketing Leader – Pioneer Corn. “Expert agronomic advice is part of the Pioneer experience, and the Fungicide Timing Solution is the latest example of how we continue to help customers achieve more bushels per acre and higher ROI on their farms.”

Forcivo^™ Fungicide Features Three Powerful Modes of Action

Forcivo fungicide adds an additional layer of confidence to the solution. It features three powerful modes of action, including a novel SDHI, and delivers broad‑spectrum disease control with long‑lasting residual activity. When applied during the optimal timing window identified by the Fungicide Timing tool, Forcivo fungicide helps protect corn plants during critical growth stages and maximize yield.

“Forcivo fungicide brings multiple modes of action that work together with both curative and preventative activity to help shield plants from damaging diseases, so crops can reach their greatest yield potential,” said Madison Riggle, U.S. Portfolio Marketing Leader, Row Crop Fungicides. “With Forcivo, the Fungicide Timing tool, and Pioneer brand hybrids, farmers gain a precision‑enabled approach to disease prevention that represents a paradigm shift in how to manage northern corn leaf blight and gray leaf spot.”

Growers participating in early use of the Fungicide Timing Solution report greater confidence in their fungicide decisions, reduced guesswork and improved peace of mind throughout the season. Trials demonstrate that applications made according to the tool’s recommended timing provided a 5 to 10 bu/A yield advantage.¹ Corteva fungicide applications made using the tool were twice as likely to achieve a measurable ROI compared with conventional application‑timing approaches.²

The Fungicide Timing Solution is now available to qualifying Pioneer customers who use a Corteva fungicide purchased through their local retailer. It will be showcased at Commodity Classic, where attendees can learn more about how advanced genetics, an AI-powered timing tool, and leading fungicides are shaping the future of corn disease management.
