Systemic insecticides are applied in the seed furrow at planting and to peanut foliage to reduce injury from tobacco thrips and decrease incidence of TSW. Research was conducted in Georgia, North Carolina, South Carolina, and Virginia in 2013 and 2014 to compare the effect of the following treatments on tobacco thrips feeding injury and expression of TSW in peanut: thiamethoxam seed treatment, thiamethoxam seed treatment followed by acephate 3 weeks after planting, phorate applied in the seed furrow at planting, and a nontreated check. Tobacco thrips feeding injury and TSW incidence were significantly higher in thiamethoxam and thiamethoxam followed by acephate‐treated peanut than peanut treated with phorate. Thiamethoxan seed treatment followed by acephate resulted in significantly lower tobacco thrips feeding injury compared to thiamethoxam seed treatment alone. Yield of Virginia market type cultivars was greater when thiamethoxam was followed by acephate applied to peanut foliage or when phorate was applied compared with nontreated peanut or the seed treatment alone. Runner market type cultivars yielded higher when phorate was applied compared with nontreated peanut while peanut treated with thiamethoxam with or with acephate yielded similar to both of these treatments.}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Monfort, Scott and Culbreath, Albert and Abney, Mark and Brandenburg, Rick and Royals, Brian and Jordan, David and Herbert, Ames, Jr. and Taylor, Sally and Malone, Sean}, year={2021}, month={Nov} } @article{brandenburg_royals_taylor_malone_jordan_hare_2021, title={Responses of tobacco thrips and peanut to imidacloprid and fluopyram}, ISSN={["2374-3832"]}, DOI={10.1002/cft2.20116}, abstractNote={AbstractTobacco thrips (Frankliniella fusca Hinds) can reduce peanut (Arachis hypogaea L.) yield if not controlled in many instances in North Carolina and Virginia. Systemic insecticides are often applied in the seed furrow at planting to suppress tobacco thrips and protect peanut yield. Foliar sprays of acephate [N‐(methoxy[methylsulfanyl]phosphoryl)acetamide] are often made regardless of the insecticide applied at planting. Imidacloprid [(NE)‐N‐[1‐([6‐chloropyridin‐3‐yl]methyl)imidazolidin‐2‐ylidene)nitramide] plus fluopyram [N‐(2‐[3‐chloro‐5‐(trifluoromethyl)pyridin‐2‐yl]ethyl)‐2‐(trifluoromethyl)benzamide])] is registered for use in peanut but information in the peer‐reviewed literature is limited regarding its effectiveness in suppressing tobacco thrips and whether or not a foliar application of acephate is needed when this product is used. Peanut injury caused by tobacco thrips was lower when phorate [diethoxy‐(ethylsulfanylmethylsulfanyl)‐sulfanylidene‐λ5‐phosphane] or imidacloprid were applied alone compared with imidacloprid plus fluopyram in 16 trials conducted in North Carolina and Virginia from 2014 to 2020. However, all insecticides applied at planting protected peanut from injury caused by tobacco thrips well enough to prevent yield loss compared with nontreated peanut. Although acephate decreased visible injury caused by tobacco thrips, yield was not affected by acephate regardless of the systemic insecticide applied at planting. The results from these trials indicate that imidacloprid plus fluopyram offers adequate suppression of tobacco thrips to protect yield. Although acephate suppressed tobacco thrips, yield was not affected by acephate.}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Brandenburg, Rick and Royals, Brian and Taylor, Sally and Malone, Sean and Jordan, David and Hare, Andrew}, year={2021}, month={Aug} } @article{royals_brandenburg_hare_jordan_taylor_malone_2020, title={Efficacy of chlorantraniliprole on southern corn rootworm in peanut}, volume={6}, ISSN={["2374-3832"]}, DOI={10.1002/cft2.20045}, abstractNote={The authors report no conflicts of interest.}, number={1}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Royals, Brian and Brandenburg, Rick and Hare, Andrew and Jordan, David and Taylor, Sally and Malone, Sean}, year={2020} }
