对59个玉米、66个甜菜和67个春油菜地进行了转基因耐除草剂（GMHT）作物管理对邻近田地边缘的影响评估。将田地分成两半，一个用GMHT作物播种，另一个用等效的常规非GMHT作物播种。边缘植被记录在三个组成部分的领域的边缘。最大的差异是在耕作面积，与更小的影响反映他们在边缘和边界。在春季油菜田，覆盖，开花和播种的植物分别低25%，44%和39%，分别在GMHT未耕作的耕作边缘。同样，对于甜菜，开花和播种分别低34%和39%，在GMHT边缘。对于玉米，效果是相反的，植物覆盖和开花分别增加28%和67%，在GMHT的一半。对蝴蝶的影响反映了这些植被的影响，在GMHT春油菜的边缘蝴蝶减少了24%。可能的原因是较低的花蜜供应在GMHT耕作的边缘和作物边缘。对于蜜蜂、腹足类动物或其他无脊椎动物，几乎没有发现大的处理差异。在常规作物旁和GMHT作物旁，除草剂喷雾漂移对植被的烧焦平均为1.6%和3.7%，这三种作物的差异都很显著。
The effects of management of genetically modified herbicide-tolerant (GMHT) crops on adjacent field margins were assessed for 59 maize, 66 beet and 67 spring oilseed rape sites. Fields were split into halves, one being sown with a GMHT crop and the other with the equivalent conventional non-GMHT crop. Margin vegetation was recorded in three components of the field margins. Most differences were in the tilled area, with fewer smaller effects mirroring them in the verge and boundary. In spring oilseed rape fields, the cover, flowering and seeding of plants were 25%, 44% and 39% lower, respectively, in the GMHT uncropped tilled margins. Similarly, for beet, flowering and seeding were 34% and 39% lower, respectively, in the GMHT margins. For maize, the effect was reversed, with plant cover and flowering 28% and 67% greater, respectively, in the GMHT half. Effects on butterflies mirrored these vegetation effects, with 24% fewer butterflies in margins of GMHT spring oilseed rape. The likely cause is the lower nectar supply in GMHT tilled margins and crop edges. Few large treatment differences were found for bees, gastropods or other invertebrates. Scorching of vegetation by herbicide-spray drift was on average 1.6% on verges beside conventional crops and 3.7% beside GMHT crops, the difference being significant for all three crops.
