Abstract
Genetically modified crop adoption in Canada has been the key driver in removing tillage as the lead form of weed control, due to increased weed control efficiency. Land use has transitioned from the use of summerfallow to continuous cropping, predominantly involving zero or minimum tillage practices. Prairie crop rotations have diversified away from mainly cereals to include three-year rotations of cereals, pulses, and oilseeds. Total herbicide volume applied has increased as crop production acres increased, but the rate of herbicide active ingredient applied per hectare has declined. Diverse crop rotations allow for weed control using herbicides with different modes of action, reducing selection pressure for resistant weed development. Herbicide-resistant weeds are an important concern for farmers, as the loss of key herbicides would make weed control exceedingly more difficult. The objective of this case study is to examine herbicide resistance weed development in the Canadian Prairies and to identify changes in resistance development following GM crop adoption.
期刊介绍：
GM Crops & Food - Biotechnology in Agriculture and the Food Chain aims to publish high quality research papers, reviews, and commentaries on a wide range of topics involving genetically modified (GM) crops in agriculture and genetically modified food. The journal provides a platform for research papers addressing fundamental questions in the development, testing, and application of transgenic crops. The journal further covers topics relating to socio-economic issues, commercialization, trade and societal issues. GM Crops & Food aims to provide an international forum on all issues related to GM crops, especially toward meaningful communication between scientists and policy-makers.
GM Crops & Food will publish relevant and high-impact original research with a special focus on novelty-driven studies with the potential for application. The journal also publishes authoritative review articles on current research and policy initiatives, and commentary on broad perspectives regarding genetically modified crops. The journal serves a wide readership including scientists, breeders, and policy-makers, as well as a wider community of readers (educators, policy makers, scholars, science writers and students) interested in agriculture, medicine, biotechnology, investment, and technology transfer.
Topics covered include, but are not limited to:
• Production and analysis of transgenic crops
• Gene insertion studies
• Gene silencing
• Factors affecting gene expression
• Post-translational analysis
• Molecular farming
• Field trial analysis
• Commercialization of modified crops
• Safety and regulatory affairs
BIOLOGICAL SCIENCE AND TECHNOLOGY
