摘要

1997年,加拿大西部开始商业化生产转基因耐除草剂(GMHT)油菜籽。到2007年,它为生产者带来了3.74亿至4.22亿美元的直接和间接净收益,部分原因是投入成本降低和杂草控制更好。在GMHT之前,杂草是通过除草剂和耕作来控制的。由于66%的生产者采用保护性耕作,与转基因油菜籽生产相关的大部分耕作已经被淘汰。由于化学品使用总数的减少,每年使用的除草剂活性成分减少了130万公斤。在比较1995年和2006年的油菜籽产量时,使用除草剂对油菜籽的环境影响每公顷减少53%,生产者对化学品的暴露减少56%。

Benefits of genetically modified herbicide tolerant canola in Western Canada
Commercial production of genetically modified herbicide tolerant (GMHT) canola began in Western Canada in 1997. By 2007, it generated between $374 million and $422 million in net direct and indirect benefits for producers, partly attributed to lower input costs and better weed control. Prior to GMHT canola, weeds were controlled by herbicides and tillage. Much of the tillage associated with GMHT canola production has been eliminated now that 66% of producers use conservation tillage. A reduction in the total number of chemical applications has resulted in a decrease of 1.3 million kg of herbicide active ingredient being applied annually. When comparing canola production in 1995 and 2006, the environmental impact of herbicides applied to canola decreased 53% per hectare and producer exposure to chemicals decreased 56%.
