Typical application timings include early April after the flag leaves emerge (Feekes growth stage 9) and at heading shortly after (head scab application/Feekes growth stage 10.5.1). [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) can be utilized in the same pass as a wheat fungicide during any application timing, offering another stress-fighting and yield-enhancing tool to optimize crop yield potential. **What benefits can TERRAMAR add to a wheat fungicide application?** - [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) minimizes the impact of weather-related stresses (e.g., cold and dry conditions) to help maintain normal physiological functions.  - [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) increases nutrient uptake and photosynthetic capacity at a critical time of yield determination. Nutrien Ag Solutions has conducted multiple field trials in which [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) was applied at different stages of wheat growth with a fungicide. As seen in the examples below, consistent yield responses and a positive return on investment (ROI)* were observed across the different timings, whether one or multiple applications of [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) were made with the grower’s standard practice (GSP).  **FLAG LEAF/FEEKES 9 FUNGICIDE APPLICATION** **![05-24 Terramar-Wheat-Feekes 9](https://blog.agricen.com/hs-fs/hubfs/05-24%20Terramar-Wheat-Feekes%209.jpg?width=600&height=356&name=05-24%20Terramar-Wheat-Feekes%209.jpg)** In a Wisconsin field trial, [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) was applied at 1 quart/acre with fungicide at the Feekes 9 growth stage (flag leaf). The addition of [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) to the grower's standard wheat fungicide program led to a +3.62 bu/a yield advantage compared to the fungicide alone, with an ROI of 2:1. (If a flag leaf fungicide application is not being made, [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) is also compatible with herbicide applications made at Feekes 8.) **HEAD SCAB SPRAY/FEEKES 10.5.1 FUNGICIDE APPLICATION** ![05-24-Terramar-Wheat-head scab 2 plots](https://blog.agricen.com/hs-fs/hubfs/05-24-Terramar-Wheat-head%20scab%202%20plots.jpg?width=900&height=468&name=05-24-Terramar-Wheat-head%20scab%202%20plots.jpg) In a field trial in Michigan, adding [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) to the grower's head scab fungicide application led to a yield advantage that ranged from +3/9 bu/a (Plot 1, ROI of 2:1) to +12.8 bu/a (Plot 2, ROI of 7:1). [![05-24-Terramar-Wheat-Head Scab Spray IN](https://blog.agricen.com/hs-fs/hubfs/05-24-Terramar-Wheat-Head%20Scab%20Spray%20IN.jpg?width=600&height=361&name=05-24-Terramar-Wheat-Head%20Scab%20Spray%20IN.jpg)](https://info.agricen.com/terramar-wheat-study-indiana) In an [Indiana trial](https://info.agricen.com/terramar-wheat-study-indiana), the yield advantage when [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) was applied with a wheat head scab fungicide was +9.41 bu/a, with an ROI of 5:1 compared to the fungicide alone.  ![05-24-Terramar-Wheat-Head Scab Spray OH](https://blog.agricen.com/hs-fs/hubfs/05-24-Terramar-Wheat-Head%20Scab%20Spray%20OH.jpg?width=600&height=369&name=05-24-Terramar-Wheat-Head%20Scab%20Spray%20OH.jpg) In Ohio, a yield advantage of +12.0 bu/a was seen when [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) was added to a wheat head scab fungicide application, with an ROI of 7:1 compared to the fungicide alone.  **FEEKES 8, 9 & 10.5.1 (3 APPLICATIONS)** [![05-24-Terramar-Wheat-3 Apps-PA](https://blog.agricen.com/hs-fs/hubfs/05-24-Terramar-Wheat-3%20Apps-PA.jpg?width=600&height=396&name=05-24-Terramar-Wheat-3%20Apps-PA.jpg)](https://info.agricen.com/terramar-wheat-study-pennsylvania) Lastly, a [Pennsylvania field trial in wheat](https://info.agricen.com/terramar-wheat-study-pennsylvania) showed an +18.0 bu/a yield advantage when [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) was applied at 1 pint/acre at three time points: First with herbicide at Feekes 8, and then with fungicides at Feekes 9 (flag leaf) and Feekes 10.5.1 (head scab spray). The ROI in this trial was 9:1. **SUMMARY** Whether applied to wheat or another row crop, a foliar application of [TERRAMAR](https://www.agricen.com/products/terramar-kelp-carbon-technology) offers a flexible and cost-effective way to enhance plant health and improve yield. **ROI calculations assume wheat at $6/bushel.* View more wheat results by downloading the [TERRAMAR Midwest wheat study](https://info.agricen.com/terramar-wheat-study-midwest).
