Rate of herbicide resistant weed development: A Canadian Prairie case study
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.
Quantifying changes in the environmental impact of in-crop herbicide use in Saskatchewan, Canada
Materials and Methods This research aims to calculate the field use environmental impact quotient (EIQ-FU) for herbicides used postemergence in the crop rotation periods of 1991 to 1994 and 2016 to 2019. The EIQ, a comprehensive tool developed by Kovach et al. (Reference Kovach, Petzoldt, Degni and Tette1992), evaluates the environmental impacts of pesticides. It encompasses three key components: farmworker impact, consumer impact, and ecological impact.
Correlating Genetically Modified Crops, Glyphosate Use and Increased Carbon Sequestration
3. Results The survey was completed by 137 Saskatchewan crop farmers. After incomplete and duplicated responses were removed, the final sample size consisted of 127 farmer data sets. Sixty-four participants provided information on land use and crop rotation practices for the 1991–1994 period, and 126 provided identical information for the 2016–2019 period. Sixty-three survey participants provided data for both time periods.
Blocking innovation: How Canada’s novel plant-breeding rules hinder progress in food production
Y ou’ve heard it before on SAIFood: Canada’s plant breeding sector is facing regulatory barriers to innovation. Today’s blog provides further evidence. Why are plant breeding and crop regulations important for Canadians? Canada is a large nation with its agricultural land comprised of different eco-zones based on soil, terrain and climate. We have hundreds of crop varieties that are capable of being grown across the country, and others that are regionally specific.
Many shoppers prefer organic food-unless GM products are cheaper, Canadian survey finds
Agricultural biotechnology produced genetically modified (GM) crops, not only provide economic benefits to farmers, but are beneficial to the environmental, human health, and consumers. At a time when no tool in agriculture can be overlooked when dealing with increasing environmental, food security, and economic pressures, what do Canadian consumers think of GM food, following over 20 years of consumption?
