Section Title
Spring Wheat FHB Fungicide Use
Trial Information
The purpose of this project is to quantify the impact of using a FHB fungicide on spring wheat.
- The grower will plant a CWRS spring wheat variety.
- The grower will manage their crop as per their normal best management practices.
- The grower will spray a FHB fungicide at the recommended rate and growth stage timing on 4 strips, alternating with 4 untreated strips.
- Strips should be full length of the field (minimum 1000 ft.) and width to allow for a full “pure” pass with combine header.
- Fusarium head blight (FHB) is a serious fungal disease that mainly affects wheat (including durum), barley, oats and corn
- One key FHB management practice as part of an integrated management approach is timely fungicide application when the risks are high. Application timing of crop protection agents can strongly influence product effectiveness.
- Trial compared producers normal timing of fungicide application to 3-5 days after the recommended timing.
Results
Trials were conducted from 2018-2021. Of the 19 sites conducted only 4 showed statistically significant differences among treatments, only one of these show significant differences between recommended timing and 3-5 days later.
