2005. 2001. Baumgarte, S., and C.C. 2004. Formulations that contain the surfactant polyoxyethylene amine can be toxic to some amphibians at environmentally expected concentrations and may affect aquatic organisms under some environmental conditions (Folmar et al., 1979; Tsui and Chu, 2003; Relyea and Jones, 2009); however, these formulations are labeled for terrestrial uses only with restrictions with respect to waterways. 2003. Crop Science 42:1863–1872. Glassmeyer. For. 2009b. Crop Protection 26(3):212–218. Wilson, R.G., S.D. 2008. Jones, D.R. Proceedings of the National Academy of Sciences of the United States of America 102(43):15389–15393. Dispersal potential in plant communities depends on environmental conditions. January 14. There is usually a delay between the introduction of a novel pesticide and the rapid rise in the number of species that have evolved resistance to it (Georghiou, 1986). Cr Pr 2-5 (6-05). Accessed April 20, 2009. Reddy. Weed Science 45:98–101. However, a new type of Bt corn introduced in 2003 to protect against corn rootworm (Diabrotica spp. Tucson, AZ. Stephen. Weed Science 56(1):72–80. Agricultural tillage systems: Water erosion and sedimentation. 2005. Champion, A.M. Dewar, M.S. will result in the introgression of the HR trait and thus a more competitive weedy hybrid, complicating management issues in wheat production (Hanson et al., 2005; Loureiro et al., 2008). Laboratory studies collectively have indicated longer development time and lower survival of valued insect herbivores, a category that includes charismatic species (e.g., monarch butterfly larvae) and moths of economic importance (e.g., the silkworm) (Naranjo, 2009). One important environmental impact of genetically modified (GM) foods is the threat to biodiversity resulting from the genetic transfer from GM crops to native plant … Herbicide-resistant crops and weed resistance to herbicides. As noted above, because the adoption of HR crops has facilitated an increase in conservation tillage and reduced the number of herbicides that growers use to control weeds, the selection pressures affecting weed communities has changed. 303–330. Storer, and B.D. More information on different types of tillage systems can be found in Appendix B. Glyphosate and multiple herbicide resistance in common waterhemp (Amaranthus rudis) populations from Missouri. (Hemiptera: Miridae) on Bt cotton in northern China. Proceedings of the National Academy of Sciences of the United States of America 106(29):11889–11894. Some agronomically important weeds (such as pigweed) are dioecious (having separate male and female plants) and thus are cross-pollinated. Weed science: Control of volunteer glyphosate-resistant soybean in cotton. Environmental consequences of agricultural practices can vary greatly at a subregional scale. Wang, and T.A. In locations where crop varieties occur with wild or weedy populations of the same or closely related species, interbreeding between a crop and its relatives may lead to exchange of genes between the cultivars or species involved. 2005. American Journal of Botany 94(4):660–673. For example, 38 weeds have developed resistance to some acetyl-CoA carboxylase (ACCase) inhibitors, and resistance to some acetolactate synthase (ALS) inhibitors has been documented in 107 weed species worldwide. Impact of production intensity on the ability of the agricultural landscape to generate ecosystem services: An example from Sweden. The few pests that have evolved resistance to Bt crops could remain susceptible to sprayed Bt insecticides that contain many Bt toxins, as long as the evolution of resistance to the toxins in Bt crops does not involve strong cross-resistance to all the toxins in Bt sprays. Challenges for maintaining sustainable agricultural systems in the United States. Powles, S.B., and C. Preston. Lang, A., R. Beck, J. Bauchhenß, G. Pommer, and M. Arndt. Kladivko, E.J. Ecological Economics 29(2):269–291. A higher proportion of herbicide-resistant GE soybean has been planted than of any other GE crop in the United States. Corn and cotton that produce Bt toxins can cause high mortality in insect pest populations in which Bt-resistance alleles are rare. Accessed March 31, 2010. Field studies on the environmental fate of the Cry1Ab Bt-toxin produced by transgenic maize (MON810) and its effect on bacterial communities in the maize rhizosphere. They also observed that an increase in the probability of adoption of HR cotton increased the probability of adoption of conservation tillage and vice versa. Transgenic Brassica napus fields and Brassica rapa weeds in Quebec: Sympatry and weed-crop in situ hybridization. 20. ed. Foz do Iguassu, Brazil: Brasilian Agricultural Research Corporation. 2008. Furthermore, the economic and environmental consequences of Bt resistance are difficult to assess because little information is available on the profitability of Cry1F corn in Puerto Rico and on how withdrawal of Cry1F corn in Puerto Rico has affected insecticide use. Harvesting data from genetically engineered crops. Water, Air, and Soil Pollution 27(3–4):391–401. weeds and Bt-resistant insects (Jasieniuk et al., 1996; Werth et al., 2008). Orr, D.B., and D.A. In Proceedings of the Weed Science Society of America,Vol. toxins. 2009. 2009 Jun;1168:72-99. doi: 10.1111/j.1749-6632.2009.04576.x. The role of laboratory, glasshouse and field scale experiments in understanding the interactions between genetically modified crops and soil ecosystems: A review of the ECOGEN project. Frisvold, G., A. Boor, and J.M. Roundup is the trademarked name of glyphosate sold by Monsanto. Accessed July 25, 2009. 2007. Heuberger, S., and Y. Carrière. Stewart, C.N., Jr., M.D. Determining the extent to which adoption of GE crops replaced specific pesticides over time requires incorporating a suite of factors, such as changes in pest pressure or pest-management strategies (e.g., see footnote on boll weevil eradication program), tillage practices, technology, and public policy (e.g., pesticide regulation, government programs) (Fernandez-Cornejo et al., 2009). Hanson, B.D., C.A. 2009. Gahan, L.J., F. Gould, and D.G. Stahlman, J.A. Brooks, G.T. (2007) and Naranjo (2009), research on the nontarget effects of Bt crops includes 135 laboratory studies of nine Bt crops and 22 Bt Cry proteins or protein combinations and 63 field studies of five Bt crops and 13 Bt proteins. Because conservation tillage practices improve soil-water infiltration, the volume of runoff is less than when conventional tillage is used. Zelaya, I.A., and M.D.K. Westgate, M.E., J. Lizaso, and W. Batchelor. Larson. A meta-analysis of effects of Bt cotton and maize on nontarget invertebrates.
