Purdue Turf Doctor

Functionality & Mechanism

This mobile diagnostic tool, developed by Purdue University, is designed for turfgrass problem identification. The app leverages a visually-driven interface that guides users through a series of questions about the plant, season, and observed symptoms. This process narrows down potential causes—including weeds, insects, and abiotic stress—and presents corresponding management options based on cultural, biological, or chemical approaches. The tool functions as a rapid-response resource for diagnosing and addressing common lawn issues.

Development & Context

• The tool was developed by researchers at the Purdue Turfgrass Science team as the latest addition to the broader Purdue Plant Doctor app suite.
• It was created to address the common challenge of correctly identifying and managing a wide range of turfgrass disorders.
• The news coverage highlights that the app is designed for a diverse audience, from beginner homeowners to experienced landscape professionals.
• The platform is supported by a social media community to further engage with its user base.

Intended Use & Scope

This app is intended as a diagnostic field guide for homeowners, land managers, and turfgrass professionals. It supports the identification of common lawn problems and provides management suggestions. While most useful in the Midwestern and Eastern United States, its information may apply to other regions. Its content is based on developer descriptions and news coverage.
