The meandering trail between too much water and not enough continues. Much of the peanuts in the state overall are looking good, with more than a quarter at pegging. Temperatures for the coming week are anticipated to be in the upper 80s, with a chance of some rain here and there.
For rank growing peanut fields where we plan to put out growth regulator (Apogee/Kudos), the target timing is 50% of laterals touching in the row middles. This helps to allow the peanut to essentially close the row before we start applying the brakes to the foliar growth. This timing helps several ways, we get to capture available photosynthesis area, shade out weeds, and shade the soil to keep pegs somewhat cool, in turn helping pegs grow up to become pods. If we are unable to apply at 50% laterals touching, being a little bit later rather than early will help to balance the benefits of closing the rows and reducing excessive foliar growth.
LLS lesions on volunteers are becoming easier to find, at least in dirty fields from epidemics of yesteryear. Bending the plants back will show the leaves near the bottom where it typically gets started. As the season progresses, fungicide management timeliness now to protect plant health will protect yield potential and help to provide more flexibility come digging time. TSW is starting to show itself more now as well. However, for TSW the most productive thing we can do now if we are seeing lots of it is to compare notes with what went on earlier in the year (variety, planting date, tillage, in-furrow product…). Pretty much all that is left now for TSW is to let it run its course.
