The potential removal of imidacloprid from water by heat‐treated kerolites
Pest Management Science - Tập 59 Số 10 - Trang 1162-1168 - 2003
M. Socías‐Viciana, E. González‐Pradas, M. A. Saifi, M.D. Ureña‐Amate, F. Flores‐Céspedes, Manuel Fernández‐Pérez
AbstractThe adsorption of imidacloprid [1‐(6‐chloro‐3‐pyridinylmethyl)‐N‐nitroimidazolidin‐2‐ylideneamine] on heat‐treated kerolite samples at 110 °C (K‐110), 200 °C (K‐200), 400 °C (K‐400) and 600 °C (K‐600) from pure water solution at 25 °C has been studied. The evolution of the surface properties of the kerolite samples, such as specif...... hiện toàn bộ
Txp40, a protein from Photorhabdus akhurstii, conferred potent insecticidal activity against the larvae of Helicoverpa armigera, Spodoptera litura and S. exigua
Pest Management Science - Tập 76 Số 6 - Trang 2004-2014 - 2020
Prakash Yallapa Shankhu, Chetna Mathur, Abhishek Mandal, D. Sagar, Vishal Singh Somvanshi, Tushar K. Dutta
AbstractBACKGROUNDTxp40, a 37 kDa protein, previously characterized from the Gram‐negative bacterium Photorhabdus akhurstii (symbiotically associates with insect‐parasitic nematode, Heterorhabditis indica), conferred insecticidal activity against Galleria mellonell...... hiện toàn bộ
Field‐evolved resistance to Bt toxin Cry1Ac in the pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), from India
Pest Management Science - Tập 67 Số 8 - Trang 898-903 - 2011
S. Dhurua, G. T. Gujar
AbstractBACKGROUND: The pink bollworm is one of the most destructive pests of cotton. Transgenic cotton producing Bt toxin Cry1Ac or a combination of Cry1Ac and Cry2Ab2 has been used effectively against this pest. However, some other insects have evolved resistance to Bt toxins in the fiel...... hiện toàn bộ
Aromatic compounds that attract Meloidogyne species second‐stage juveniles in soil
Pest Management Science - Tập 77 Số 10 - Trang 4288-4297 - 2021
Yuji Oka
AbstractBACKGROUNDNematode attractants could serve in nematode control strategies by combining with chemical or biological nematicides or by interrupting the nematodes' host‐finding process. The attractiveness of some benzenoid aromatic compounds, mainly benzoic acids, alcohols, aldehydes and phenols, to second‐stage juveniles (J2...... hiện toàn bộ
Assessment of leaching potential of aldicarb and its metabolites using laboratory studies
Pest Management Science - Tập 57 Số 12 - Trang 1135-1141 - 2001
Luca L. Fava, Paola Bottoni, A. Crobe, Anna Barra Caracciolo, Enzo Funari
AbstractThe metabolites of pesticides can contaminate groundwater and pose a risk to human health when this water is used for drinking. This paper reports the results of a laboratory study on aldicarb and its main metabolites, aldicarb sulfone and aldicarb sulfoxide. Aldicarb and its metabolites showed Koc values (6–3...... hiện toàn bộ
Leaching behaviour of azoxystrobin and metabolites in soil columns
Pest Management Science - Tập 65 Số 9 - Trang 1009-1014 - 2009
Rakesh Kumar Ghosh, Neera Singh
AbstractBACKGROUND: Azoxystrobin [methyl (E)‐2‐{2‐[6‐(2‐cyanophenoxy)pyrimidin‐4‐yloxy]phenyl}‐3‐methoxyacrylate], a strobilurin fungicide, is a broad‐spectrum, systemic and soil‐applied fungicide. Azoxystrobin has been registered for rice cultivation in India, but no information is available on its leaching behavio...... hiện toàn bộ
Estimating economic thresholds for site-specific weed control using manual weed counts and sensor technology: An example based on three winter wheat trials
Pest Management Science - Tập 70 Số 2 - Trang 200-211 - 2014
Martina Keller, Christoph Gutjahr, Jens Möhring, Martin Weis, Markus Sökefeld, Roland Gerhards
Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins
Pest Management Science - Tập 68 Số 1 - Trang 16-30 - 2012
Richard H. Coupe, Stephen J. Kalkhoff, Paul D. Capel, Caroline Grégoire
AbstractBACKGROUND: Glyphosate [N‐(phosphonomethyl)glycine] is a herbicide used widely throughout the world in the production of many crops and is heavily used on soybeans, corn and cotton. Glyphosate is used in almost all agricultural areas of the United States, and the agricultural use of glyphosate has increased ...... hiện toàn bộ
Impact of Spodoptera frugiperda neonate pretreatment conditions on Vip3Aa19 insecticidal protein activity and laboratory bioassay variation
Pest Management Science - Tập 72 Số 4 - Trang 837-844 - 2016
Karen F. Da Silva, Terence Spencer, Carolina Camargo, Blair D. Siegfried, Frederick S. Walters
AbstractBACKGROUNDVariation in response to insecticidal proteins is common upon repetition of insect bioassays. Understanding this variation is a prerequisite to detecting biologically important differences. We tracked neonate Spodoptera frugiperda (J.E. Smith) susceptibility to ... hiện toàn bộ
Auxin herbicides: current status of mechanism and mode of action
Pest Management Science - Tập 66 Số 2 - Trang 113-120 - 2010
Klaus Großmann
AbstractSynthetic compounds that act like phytohormonal ‘superauxins’ have been among the most successful herbicides used in agriculture for more than 60 years. These so‐called auxin herbicides are more stable in planta than the main natural auxin, indole‐3‐acetic acid (IAA), and show systemic mobility and selective action, preferentially...... hiện toàn bộ
