Comments From Dan Anco Clemson Peanut Notes No. 75 2023

The following are comments from Dan Anco with Clemson University
With the start of June a week out, planting is about 70% completed and moving along well. Stands have generally been good to fair.


Received rains have helped with activation of residual herbicides. If weeds are starting to come up after planting and initial residuals have been applied (e.g., 3 weeks after planting) and it will be another 10 to 14 days until the next scheduled post application (Cadre, for example) will take place, applying an early post while weeds are still small will help keep them in check while they are more manageable. Where valor injury has occurred due to rain splash on emerged peanut, this is passing and peanuts grow out of it well.


Where soil tests are less than 0.4 lb/A B, boron can be added in the first fungicide application or in an early-season herbicide application. Total B application in a field in a season not greater than 0.5 lb/A helps to avoid toxicity.


Most fields have been recently planted and are not yet at flowering. As a guideline, land plaster we target putting out near flowering so that it can be available following pegging when the pod begins to develop. Heavy rain, like what many areas received over the last week, can result in wet piles that may need to dry out more before being about to be effectively spread. This will be okay. A week or so delayed application of land plaster will not cause a major issue, an appreciated contrast compared to if a timely herbicide/fungicide application were to be delayed a week or more. One of the benefits of not putting out land plaster too early is that there is less chance of heavy rainfalls washing or leaching some away.
