Attached are images from a field where challenges at planting resulted in some rows (about 25%) not being inoculated. The difference compared to rows receiving proper inoculation can be seen. Our target for assessing inoculation is an approximate average of 15 active nodules per taproot by about 45 DAP. Healthy and active nodules appear red or pink on the inside when cut open, whereas inactive nodules are white inside. Our recommendation for fields with inoculant failure is to apply approximately 100 units of N (100 lb/A 21% AMS). In this particular field, because most of the rows were inoculated, a broadcast application over the entire field would not be recommended to save on costs. Knifing in the N for the individual rows that are deficient, or dripping liquid N in adjacent row middles, may be a tedious process but would be more cost effective compared to a broadcast application. If N is applied or not, come time to assess the field for maturity to determine when to dig it, fields such as this where most rows have been inoculated should be determined based on the rows that were inoculated, since that is where the bulk of the crop will be produced. If fields are closer to 50% inoculated, determining maturity can take into account all rows, but digging decisions then would still remain a balance of pods to preserve (from over maturity) versus pod maturity/weight to gain from letting the immature pods develop longer. Weather conditions during the season as we move through pod fill likewise interact to influence the presence of split crops even when inoculation is uniform across a field, and the usual factors (field/impending weather conditions, canopy health...) will also need to be taken into consideration in tailoring individual field decisions.

Also attached is a peanut leaf symptomatic with leaf scorch. This disease is not an economic concern and does not require separate fungicides to be applied beyond those that are already used in peanut for leaf spot management.
