Influence of Planting Date, Fungicide Seed Treatment, and Phorate on Peanut in North Carolina

The presented research provides further evidence of important pest management strategies for peanut production, including planting date strategies, using treated seed, increasing plant stands, and applying phorate in the seed furrow at planting. With respect to conventional production, the data suggest that planting fungicide-treated seed and applying insecticide, in this case phorate, is recommended across planting dates. These data also illustrates the expanded planting window gained by using treated peanut seed as resource, or other constraints, allows planting during early May. Further, treated seed increased peanut stands, which aided in reducing thrips injury and increased yields. In regards to organic producers, these data suggest mid- to late-May plantings may experience more favorable climatic conditions that improve plant vigor and growth, thus promoting emergence and improved plant stands. Later planting dates and increased plant stands also aided in thrips management as less injury was seen in both cases and improved peanut yields. Seeding rate may also be increased to maximize the aforementioned benefits. The above recommendations will aid in improving pest management and peanut yields for North Carolina producers. These data can also be used to assist growers in determining the impact of poor stands on yield and the economic value of replanting.
