The North Carolina Peanut Growers Association and the North Carolina Extensive Service recognizes the highest yielding peanut producers each year at annual county production meetings. A total of 74 of these farmers were surveyed to determine their pest management and production practices during 2010-2013. The percentage of peanut yields among farmers in various yield categories (lbs/acre) included: 2,500-3,000 (2%), 3,001-3,500 (2%), 3,501-4,000 (5%), 4,001-4,500 (15%), 4,501-5,000 (24%), 5,001-5,500 (27%), 5,501-6,000 (18%), 6,001-6,500 (5%), and 6,501-7,000 (2%).

Fifty-eight percent of farmers planted before May 15 with 42% planting after this date. Several farmers planted both prior to and following May 15. Although seeding rates varied for some farmers, 30% planted between 100-120 lbs seed/acre, 45% planted between 121-140 lbs seed/acre, and 25% planted 140 lbs seed/acre or more. Eighty-seven percent of farmers reported planting in in single rows while 13% reported planting in twin rows. Twenty-two percent of farmers planted in rows spaced 38 inches apart with the balance of producers planting in rows spaced 36 inches apart (78%). Twenty percent of farmers irrigated. Seventy-five farmers disked, 47% field cultivated, 43% bedded, and 34% ripped and bedded. Only 18% of farmers chisel plowed or mold board plowed. One farmer no tilled while 27% of farmers strip tilled. All farmers had at least two crops between peanut plantings. Ten percent of farmers had 2 crops while 41% had 3 crops, and 49% planted at least 4 crops between peanut plantings. Boron was applied by 97% of farmers while 76% and 77% of farmers applied manganese and Bradyrhizobia inoculant, respectively. Forty-seven percent of farmers applied the plant growth regulator prohexadione calcium (Apogee). Twenty-eight percent of growers planted one cultivar, 30% planted two cultivars, 24% planted three cultivars, and 18% planted four or more cultivars. Popular cultivars included CHAMPS (42%), Bailey (41%), Phillips (39%), Sugg (27%), and Perry (27%). Less frequently planted cultivars included NC-V 11 (20%), Gregory (16%), VA 98R (15%), Wilson (4%), Brantley (4%), and NC 12C (3%). Farmers treating peanut with in-furrow insecticides applied Temik (57%), Thimet or Phorate (10%), and Orthene or Acephate (14%). The primary postemergence applications of insecticides included Asana XL (34%), Karate Z (19%), and Lorsban (38%). The percentage of farmers spraying less than 3, 4, 5, 6, or greater than 6 times for leaf spot/stem rot were 7%, 25%, 48%, 15% and 5%, respectively. Thirty-eight percent of farmers fumigated with metam sodium for CBR while 12% treated peanut to control spider mites.
