Soybean Growth Stages

Soybeans on the average are at growth stage V5. Some soybeans are approaching the R1 stage which is the beginning of flowering. It is important to understand the growth stages especially when considering the application of a fungicide for disease control. Be sure to read the label of the specific fungicide that you may use and apply at the appropriate growth stage of soybeans. Consider the following when determining the economics of fungicide applications:

1. Disease pressure and/or forcast

2. Varietal suseptibility

3. Crop rotation

4. Crop Growth Stage/Maturity

5. Field Environment (River bottoms vs. upland)

6. Grain Prices

7. Cost of fungicide and application
