Purdue Extension Corn Field Scout

Functionality & Mechanism

This digital field guide, developed by Purdue Extension, serves as a comprehensive, science-based reference for corn production management. The app aggregates information on crop growth stages, soil fertility, and pest identification. It integrates built-in calculators to determine seeding rates, estimate yield loss, and calculate nutrient recommendations. The interface facilitates problem diagnosis by leveraging a library of high-quality images and descriptive guides for common diseases, weeds, and signs of herbicide injury.

Development & Context

• Developed by Purdue Extension specialists, the app aims to provide grain producers and crop advisers with more accessible, research-based management information.
• It was created as a mobile version of the popular annual Corn and Soybean Field Guide, a print resource used for over two decades.
• The news coverage notes its 2017 release on both iOS and Android platforms as a user-friendly reference tool for use throughout the growing season.

Intended Use & Scope

This application is designed for grain producers, crop advisers, and agribusiness professionals as an in-field reference tool. It provides science-based information and calculators to support crop management decisions. Information presented is based on developer descriptions and news coverage, not peer-reviewed efficacy studies, and is not a substitute for professional agricultural consultation.
