由于抗除草剂杂草在粮食出口国的农田中蔓延，它们的种子可能作为进口粮食的污染物被引入其他国家。抗性基因通过种子和花粉传播会造成重大的经济损失。为了评估问题的严重程度，我们调查了西澳大利亚进口小麦中抗除草剂黑麦草（Lolium rigidum）的污染情况。从小麦运输中回收了一年生黑麦草种子，并对种子进行了生物测定，以确定其对澳大利亚常用除草剂的抗性，这些除草剂包括：双氯草甲基、乙氧基醚、氯磺隆和草甘膦。在2006年和2007年进口的20公斤小麦中检测出近4500颗黑麦草种子。2006年和2007年对双氯草畏的抗性分别为35%和15%、5%和6%，对氯磺隆的抗性分别为56%和60%。在这两年中，没有人对草甘膦产生抗性。由于抗除草剂杂草对作物的污染可能是一种普遍现象，因此有必要对进口粮食进行监测，以阻止抗除草剂杂草进一步蔓延到进口国。
As herbicide-resistant weeds have spread in the agricultural fields of grain-exporting countries, their seeds could be introduced into other countries as contaminants in imported grain. The spread of resistance genes through seed and pollen can cause significant economic loss. In order to assess the extent of the problem, we investigated the contamination by herbicide-resistant annual ryegrass (Lolium rigidum) of wheat imported from Western Australia into Japan. Annual ryegrass seeds were recovered from wheat shipments and seed bioassays were conducted to identify resistance to the herbicides that are commonly used in Australia: diclofop-methyl, sethoxydim, chlorsulfuron, and glyphosate. Nearly 4500 ryegrass seeds were detected in 20 kg of wheat that was imported in both 2006 and 2007. About 35% and 15% of the seeds were resistant to diclofop-methyl, 5% and 6% were resistant to sethoxydim, and 56% and 60% were resistant to chlorsulfuron in 2006 and 2007, respectively. None was resistant to glyphosate in either year. As the contamination of crops by herbicide-resistant weeds is probably a common phenomenon, the monitoring of incoming grain shipments is necessary to stem the further spread of herbicide-resistant weeds into importing countries.
