JLA Report for July 23 2015

— Written By

The peanut crop in the V-C region has improved in some areas due to recent rains, although distribution of rain continues to be variable. Approximately 30% of the crop in the region is experiencing considerable drought stress which ultimately will impact production. The lower southeastern peanut area of the V-C is experiencing the broadest stress, although some sections of North Carolina continue to be dry. In the upper V-C excessive rainfall has been experienced.

Many growers have completed their first fungicide spray for leaf spot and stem rot. Foliar-feeding insect populations are currently below threshold levels. Many growers are applying prohexadione calcium to manage vine growth and enhance pod retention. Tomato spotted wilt is beginning to appear, especially where peanut stands are below optimum. Boron and manganese are being applied in some fields to correct deficienmces. Images of peanut from Lewiston-Woodville in northeastern North Carolina planted in early, mid- and late-May are provided.

The peanut crop in the V-C region is variable but continues to be in generally good shape. Estimates remain the same for planted acres at 230,000 or 93,000 ha for the region. However, the yield estimate is 3,900 pounds/acre (4,370 kg/ha) at the current time.
