The Bayer Spray app helps farmers effectively plan agricultural spray applications for their fields. Download the app. Start your spray planning today. Calculate erosion/runoff mitigation points based on EPA guidelines. Get field-specific weather forecasts — including temperature and inversion risk. Enable the creation and retention of application records. Forecast Section - Helps you identify weather conditions and inversion risk prior to spray applications. • Hourly, location-specific forecast of temperature, relative humidity, wind speed (adjusted to 6 feet) and direction, and inversion risk. • Specific field location inversion-risk forecast. • The weather forecasts leverage publicly available weather data and models from the National Oceanic and Atmospheric Administration (NOAA) and unique models from Bayer Crop Science’s weather scientists to forecast weather conditions — including the likelihood of an inversion — that help growers and applicators planning to spray a pesticide. Fields Section (Formerly Location) - Allows for application planning at the field level. • The list of saved fields provides information on any mitigation points calculated, as well as certain application risks for upcoming planned applications. • NEW alerts help applicators understand how to plan for compliant sprays on their unique fields. Compliance Section - A new addition to the app that provides a runoff/erosion mitigation calculator to help farmers and applicators plan applications. • The calculator keeps a running total of mitigation points (by field) accumulated as the form is completed. • Calculations can be completed for multiple fields at a time. • Save, edit, and share field-specific calculations to track compliance. SprayLog Section (Formerly Record) - Helps applicators with mandatory dicamba recordkeeping requirements. • Elements required by the federal OTT dicamba product label are included to enable greater ease of use. • Applicators can save and export field records. • The information you enter in the application records is stored on your mobile device. Information provided by the Bayer Spray app is for planning purposes only, and is not a substitute for reading and following all pesticide label directions. It is the applicator's responsibility to comply with all laws relevant to the applicator's farming operation, including pesticide label compliance.

The clearest difference is rating: Bayer Spray at 3.8 against MFA Agronomy Guide's 3.6. Bayer Spray also leads on ratings volume (59 vs 7). MFA Agronomy Guide's advantage is review sentiment (50% vs 40%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Bayer Spray holds the better App Store score, 3.8 against 3.6. That said, the two scores are not equally well evidenced: Bayer Spray has 59 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 50% of MFA Agronomy Guide's written reviews are positive against 40% of Bayer Spray's, so the app with the better star average is not the one people write more warmly about.
MFA Agronomy Guide ships an update every 2 months, Bayer Spray monthly. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
