Influence of in-furrow or post emergent insecticide treatment on peanut yield.a. Therefore, effective control of pest populations is often essential for cost-effective crop production. Imidacloprid (Marathon), which has a water solubility of 0.51 g/L or 500 ppm, tends to be less effective against flower- and pollen-feeding insect pests including WFT. This is why acetamiprid is not included in Table 1. Acephate applied as a liquid spray and phorate applied in a granular formulation did not affect peanut response to commercial inoculant (Jordan et al., 2017; Tubbs et al., 2015). Also, given the expense of seed and the expense in correcting nitrogen deficiency following failure of commercial Bradyrhizobia inoculant (Jordan et al., 2017), research is needed to determine if negative interactions occur when Bradyrhizobia inoculant is applied in the seed furrow with imidacloprid and to determine if thrips control is compromised by this combination. Technology Transfer, North Carolina Cooperative Extension Service Pub. The experiment was also conducted in commercial production fields near Elizabethtown (2012) and Wilson (2012-2014). Studstill, W.S. Faske, B.L. 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). Lot of bad publicity and misinformation has been damaging the greenhouse industry. Peanut pods were dug and vines inverted based on pod mesocarp color (Williams and Drexler, 1981). The commercial inoculant at this rate delivers approximately 5.0 × 1012 viable Bradyrhizobia cells/ha. Imidacloprid Pesticide Imidacloprid is a systemic insecticide that acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act … In a second experiment conducted during the same time period, a commercial liquid formulation of Bradyrhizobia inoculant was applied alone or with imidacloprid in fields with and without plantings of peanut in recent years. With the increase in use of imidacloprid in peanut to control thrips, determining the need to apply acephate to emerged peanut as compared to other systemic insecticides is important. Injury from thrips feeding was recorded 2 weeks after acephate was applied postemergence using an ordinal scale of 0 to 5, where 0 = no damage, 1 = noticeable feeding but no stunting, 2 = noticeable feeding and 25% stunting, 3 = feeding with blackened terminals and 50% stunting, 4 = severe feeding and 75% stunting, 5 = severe feeding and 90% stunting (Drake et al., 2009). The insecticide imidacloprid and spinetoram resulted in fewer numbers of thrips and higher yields than profenofos and λ –cyhalothrin. The main effects of in-furrow insecticide (P = 0.0020; F = 7.4) and POST acephate application (P = 0.0349; F = 7.4) were significant for peanut yield when pooled over all experiments. 3. Tobacco thrips (Frankliniella fusca Hinds) is an important pest in peanut (Arachis hypogaea L.) in North Carolina and injury from this insect can lower yield. better, safer application and the possibility of not using some of these products… 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). Data for injury caused by thrips and pod yield were subjected to ANOVA for a 10 (experiment) by 2 (imidacloprid treatment) by 2 (Bradyrhizobia treatment) factorial treatment arrangement. Means of significant main effects and interactions were separated using Fisher's Protected LSD at P < 0.05. The question here is. 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. Levinson, K.M. See all author stories here. Jordan et al. 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. R.L. The banana thrips (Thrips hawaiiensis), which is one of the most common flower-inhabiting thrips, currently causes serious damage to banana trees in China. By blocking nicotinic acetylcholine receptors, … While I know some on the forum are against the 3 in one product, I am more interested in understanding the label as I am trying to learn. The Western flower thrips (WFT, Frankliniella occidentalis) is a global polyphagous pest that is often dependent on chemical control.Imidacloprid has been a commonly used chemical insecticide for effective control of WFT. Acephate and imidacloprid were applied in 18.9 L/ha aqueous solution immediately after seed drop but prior to slit closure. Incidence of tomato spotted wilt was sporadic and did not exceed 5% for any experiment or treatment. Generally, the insecticides contain Spinosad, Pyrethrin, Malathion, Sevin, Imidacloprid, Permethrin, Azadirachtin, Salt of fatty acid, etc. In order to develop controls, it is essential to understand the feeding behavior of these pests. Imidacloprid has also been shown to be effective against other thrips species. WFT feeding on leaves (both nymphs and adults) tend to be more susceptible to systemic insecticides than when feeding in flowers. Mahoney, P.D. 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. Acephate applied 3 weeks after planting generally reduced injury from thrips. However, when the interaction was explored, only the magnitude of injury was different between experiments, but similar trends were observed across experiments with respect to the imidacloprid treatment. This study, which was conducted in 2014 and 2015, demonstrated that treating corn seeds with thiamethoxam (1.0 and 2.0 g AI/kg of seeds), clothianidin (1.0 and 2.0 g AI/kg of seeds), and imidacloprid (2.0 g AI/kg of seeds) reduced thrips infestations and prevented yield losses throughout the corn growing season. Is Imidaclopridnot not Imidacloprid? It is only registered for use as foliar or sprench applications. However, it is possible that the metabolite — clothianidin — is actually responsible for killing the thrips. Such as-Spinosad– Best for killing caterpillars, leafminers, flies, thrips, and foliage-feeding beetles As I recall, some flea collars contain imidacloprid. Fields at Lewiston-Woodville and Rocky Mount had peanut planted 3 years prior. Additionally, response of peanut to Bradyrhizobia inoculant was independent of systemic insecticide applied in the seed furrow with inoculant. None of the neonicotinoid … signipennis, –– e c 5 6 Open in new tab Download slide. Use at least one card per house or one per 2,000 ft2. Thiamethoxam, Clothianidin, and Imidacloprid Seed Treatments Effectively Control Thrips on Corn Under Field Conditions December 2018 Journal of Insect Science 18(6) Plot size was 2 rows spaced 91-cm by 9 m. Production and pest management practices other than those associated with thrips control were held constant across the entire test area and were based on Cooperative Extension Service recommendations for North Carolina (Jordan et al., 2017). Definitely agree, Bill. Imidacloprid; Imidacloprid has a similar action like nicotine which is found as a natural compound in plants such as tobacco. North Carolina Cooperative Extension Service Pub. In-furrow and foliar insecticide treatments were considered fixed effects with year and replication considered a random effect. What Are the Emerging Trends Affecting Indoor Farming? Tubbs, D.L. 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. Imidacloprid is also used to control fleas in dogs and cats, although you wouldn't use the products listed above for your pets. Pod yield was similar regardless of in-furrow treatment when acephate was applied postemergence. In addition, the anthophilic (inhabiting flowers) nature of WFT limits their exposure to systemic insecticides for several reasons: The active ingredient is not readily transported into flower tissues (petals and sepals). Water solubility determines how rapidly the active ingredient is absorbed by roots and translocated throughout plant parts such as leaves and stems. The active ingredient of a systemic insecticide may degrade faster in flower parts and differences in the transpiration rates between flowers and leaves may result in flowers being less efficient sinks for the active ingredient of systemic insecticides. Systemic insecticides may not provide fast knockdown to prevent thrips damage to flowers when abundant populations are present. (2015) also reported no adverse effect of the systemic insecticide phorate on peanut yield response to Bradyrhizobia inoculant.

However, availability of aldicarb was reduced following the 2009 growing season and farmers and their advisors began using other systemic insecticides to control thrips. 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). One common question asked by greenhouse producers is associated with the effectiveness of systemic insecticides against the western flower thrips, Frankliniella occidentalis. Experiment, imidacloprid treatment, and Bradyrhizobia treatment were considered fixed effects. Additionally, the resistance of WFT to imidacloprid increased slower and decreased faster compared with resistance to other active ingredients like phoxim and emamectin benzoate [ 22 ]. Brandenburg, D.L. (2007) reported acephate did not significantly improve thrips control when preceded by phorate or aldicarb in-furrow. (2018), who reported increased peanut yield compared to non-treated peanut, but no yield increase when preceded by an in-furrow insecticide treatment. Imidacloprid … Instead, they feed within the mesophyll and epidermal cells of leaf tissues. Peanut was planted in conventionally-prepared seedbeds as described previously. What other chemical we can use that is no threatening to mammals including us? Mean (±SE) thrips feeding damage index (FDI) over four replications of each treatment in two peanut cultivars. Leaf-feeding more easily results in the insects imbibing toxic concentrations of the active ingredient of systemic insecticides.

Field evaluation of systemic imidacloprid for the management of avocado thrips and avocado lace bug in California avocado groves Author: Byrne, Frank J., Humeres, Eduardo C., Urena, Anthony A., Hoddle, Mark S., Morse, Joseph G. Source: Pest management science 2010 v.66 no.10 pp. Thank you Raymond.Good sound information .I have commercial greenhouses .I used these products for years.I have bee hives close to my greenhouses and they flourish. What makes the Imidacloprid in Merit better for killing Chilli Thrips than Imidaclopridin any of the other products. 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). (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. Imidacloprid kills insects by contact and ingestion and is especially systemic when used as a … AGPRO Imidacloprid translocates well in the leaves and roots of plants. As they do their daily work, they get even residue on their bodies, and can kill the whole hive. I … Royals, D.J. rust thrips, the fingers were found free from blemishes in the bud injection technique that uses imidacloprid as well as bunch sleeving at the shooting stagein Poovan banana during 2009–10 and 2010–11 (Table 1). Herbert et al. When pooled over in-furrow insecticides, an application of acephate to the peanut foliage 3 weeks after planting increased yields compared to no application (180 kg/ha increase). It is necessary to evaluate the thrips species composition in Texas cotton, as well as the impact of imidacloprid and thiamethoxam seed treatments on the thrips populations. Planting date and other cultural practices affect damage to cotton from thrips injury. Herbert et al. The increase in yield was most likely associated with previous history in these fields. Proper use is key. The cultivar Bailey expresses resistance to TSW (Brandenburg, 2017; Isleib et al., 2011; Shew, 2017). Jordan, A.T. Hare, A. Sadeghpour, S.P. Means of significant main effects and interactions were separated using Fisher's Protected LSD test at P ≤ 0.05. Imida 100ML(IMIDACLOPRID 30.5% SC) Systematic Insecticide Control of Sucking PEST APHIDS, JASSIDS, Thrips, White Fly and TERMITES Powerful: Amazon.in: Garden & Outdoors I am from Sri Lanka and I have a problem due to attack from thrips to my gerbera plants which were cultivated in my net house and also to flowers.Any body pl. Acephate was applied 3 weeks after planting at 0.4 kg/ha using a CO2-pressurized backpack sprayer calibrated to deliver 140 L/ha at a pressure of 275 kPa. These data indicate that imidacloprid protects peanut as well as or more effectively than the systemic insecticides acephate and phorate and that imidacloprid is compatible with Bradyrhizobia inoculant. In contrast, in those fields where peanut had been planted no more than 2 or 3 years prior to the experiment, yield was not affected. A less water-soluble systemic may persist longer, but may not be as effective unless the rate is adjusted to compensate for the slower mobility. Marasigan, Y. Chu, H.T. WFT have piercing-sucking mouthparts, but they do not feed exclusively in the phloem sieve tubes. Johnson; Utilization of Imidacloprid to Control Thrips in Peanut in North Carolina. Corn thrips are major pests of corn sown in the summer in China, and the identification of effective control measures against thrips will help reduce economic losses. Acephate (Orthene 97, Valent USA, Walnut Creek, CA), imidacloprid (Admire Pro, Bayer CropScience, Research Triangle Park), and phorate (Thimet 20 G; AMVAC Chemical Corporation, Los Angeles, CA) were applied in the seed furrow at 1.1, 0.21, and 0.56 kg ai/ha. I am up to a professional applicator responsibility and accountability. 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). Jordan, B.R. Table 1 presents the systemic insecticides labeled for use in greenhouse production systems that can be applied to the soil/growing medium, and their corresponding water solubilities. Genfarm Imidacloprid 200SC Insecticide ... 7 days Apply at first sign of whitefly or melon thrips infestation. When pooled over the seven experiments, imidacloprid applied in the seed furrow at planting provided increased peanut yield compared to acephate, but was similar to phorate. Also a close look at target areas for which the specific greenhouse crops are to be sold and used, exposing the pesticide to bees. Peanut injury from tobacco thrips feeding was reduced by acephate, imidacloprid, and phorate applied in the seed furrow at planting compared with non-treated peanut. Peanut receiving in-furrow and/or post emergent insecticide treatment reduced injury compared to the non-treated peanut (Table 1). Stalker, C.C. Previous research (Jordan et al., 2017) also demonstrated that peanut yield response to acephate applied in the seed furrow at planting in a manner similar to the current study increased yield irrespective of Bradyrhizobia treatment.
