Prevention of glyphosate resistant kochia scoparia in Western Canada

地肤（Kochia scoparia）是加拿大南部大草原的一种重要杂草，已经对用于其控制的大多数常见除草剂具有抗性。地肤目前在加拿大西部使用草甘膦进行控制，在所有作物播种前施用，并在抗草甘膦油菜和甜菜中施用。抗草甘膦地肤已经在美国被发现，引起了人们对抗草甘膦地肤的关注，无论是在这里被选择还是通过种子被运到加拿大西部。

Kochia (Kochia scoparia) is a significant weed of the southern Canadian Prairies, one that is already resistant to most common herbicides used for its control. Kochia is currently controlled in Western Canada using glyphosate, applied pre-seeding in all crops, and in-crop in glyphosate resistant canola and sugar beets. Glyphosate-resistant kochia has been identified in the US, raising concerns about resistant kochia, either by being selected here in or introduced by seed transported to western Canada.
