Importance of Growth Stages
Accurate identification of soybean growth stages is essential for applying harvest aids effectively. The R6.5 stage is critical, as applications made too early can lead to significant yield reductions.
Recommended Chemicals
Paraquat is the most widely used harvest aid due to its quick desiccation properties. Sodium chlorate is also mentioned as an option, but farmers should be aware of the specific application guidelines for each.
Cautions on Application Timing
Farmers are advised to wait until the R7 stage for safer applications, as this reduces the risk of yield loss. Early applications can lead to quality issues, especially if adverse weather occurs after treatment.
Key takeaways
5 things worth knowing
- 01
