(2007) reported that acephate further reduced injury above that of in-furrow insecticides and increased yield compared with non-treated peanut or peanut treated only with insecticides applied in the seed furrow at planting. Acephate can also be applied in the seed furrow at planting, but in some instances slower emergence of peanut after application of acephate has been observed (Brandenburg, 2017). It may provide systemic protection to flower buds, which allows plants to flower and minimizes feeding injury resulting in good flower quality. Acephate and imidacloprid were applied in 18.9 L/ha aqueous solution immediately after seed drop but prior to slit closure. By blocking nicotinic acetylcholine receptors, … The North Carolina Peanut Growers Association, the National Peanut Board, and the Feed the Future Peanut and Mycotoxin Innovation Lab provided partial funding for this research. Registered use in onions, vegetable brassica, lettuce and grapes. Efficacy of commercially-applied inoculant can be compromised by other products applied in the seed furrow in combination with the inoculant (Jordan et al., 2010). The question here is. In summary, due to the feeding behavior of the WFT, systemic insecticides, when applied to the soil/growing medium, in general, may be less effective than when applied as foliar sprays. WFT feeding on leaves (both nymphs and adults) tend to be more susceptible to systemic insecticides than when feeding in flowers. Royals, D.J. Acephate applied in the seed furrow at planting or the POST treatment alone had increased injury compared to any combination of in-furrow insecticide followed by the POST treatment. Means of significant main effects and interactions were separated using Fisher's Protected LSD at P < 0.05. which insecticide I can use to control onions thrips? 1129-1136 The experiment was conducted in North Carolina at the Border Belt Tobacco Research Station near Whiteville (2014), the Peanut Belt Research Station near Lewiston-Woodville (2012 and 2013), and the Upper Coastal Plain Research Station near Rocky Mount (2012-2014). A highly water-soluble systemic insecticide may kill insect pests quickly; however, it may not provide long-term or sufficient residual activity compared to a less water-soluble systemic insecticide. If banned for use. AG-331, Epidemiology of spotted wilt disease of peanut caused by tomato spotted wilt virus in the southeastern US, Response of new field-resistant peanut cultivars to twin row pattern or in-furrow applications of phorate for management of spotted wilt, Epidemiology and management of tomato spotted wilt in peanut, Peanut cultivar response to damage from tobacco thrips and paraquat, American Peanut Research and Education Society, Role of insecticides in reducing thrips injury to plants and incidence of tomato spotted wilt virus in Virginia market type peanut, Management of spotted wilt virus vector Frankliniella fusca (Thyanoptera: Thripidae) in Virginia market type peanut, Sullivan peanut. Bradyrhizobia is often applied in the seed furrow at planting as a liquid formulation to ensure biological nitrogen fixation (BNF), especially in fields without a previous history of peanut plantings (Elkan et al., 1995; Morgan et al., 2014; Rhodes et al., 2008). Adequate control of tobacco thrips, Frankliniella fusca (Hinds), is necessary in North Carolina and Virginia to protect yield (Brandenburg, 2017; Drake et al., 2009; Herbert et al., 2007; Hurt et al., 2005; Marasigan et al., 2016) and minimize incidence of tomato spotted wilt (TSW) caused by tomato spotted wilt virus (family Tospoviridae, genus Orthotospovirus) of peanut (Culbreath et al., 2003, 2008; Culbreath and Srinivasan 2011). was used for both experiments. Experiments were conducted in North Carolina from 2012 through 2014 at the Peanut Belt Research Station located near Lewiston–Woodville on a Norfolk sandy loam (fine loamy, siliceous, thermic, Aquic Paleudalts) with organic matter ranging from 0.5 to 1.2% and pH 5.9 to 6.1, during 2012 and 2014 at the Upper Coastal Plain Research Station on a Goldsboro loamy sand (fine-loamy, siliceous, thermic Aquic Paleudalts), and in 2013 and 2014 in farmer fields near Wilson on an Aycock fine sandy loam (fine-silty, siliceous, thermic, Typic Paleudults).
